HSE POLICY,OBJECTIVES OF THEPTW SYSTEM AND

ITS CUSTODIANSHIP



CHAPTER 1

HSE POLICY, OBJECTIVES OF THE PTW SYSTEM AND CUSTODIANSHIP

The GASCO HSE Policy includes the statement that ‘GASCO shall conduct activities in a manner designed to minimise HSE risk to a level which is As Low As Reasonably Practicable (ALARP)’.

Amongst its activities, GASCO requires to carry out work, which may be in Operational or Non-Operational Areas of Plant facilities or Pipelines. In order to manage the potential risks associated with this activity to ALARP, GASCO has developed a Management System of Control, called the “GASCO Permit to Work (PTW) System”. The GASCO Permit to Work System is described in this Manual.

The United Arab Emirates Law No. 8, for year 1980, on Conservation of Petroleum Resources Chapter V, Articles 91 & 92, and Ministerial Order No. 32 for year 1982,

Protection of Employees Against Occupational Hazards Article-1, state that:

“Every employer shall provide adequate preventative equipment to protect workers against the dangers of employment accidents and occupational diseases that may occur during the work and also against fire hazards that may result from the use of machines and other equipment. He shall also adopt all other preventative methods ordered by the Ministry of Labour and Social Affairs.”

“Every worker shall use the protective equipment and the clothing supplied to him for this purpose, shall comply with all the instructions given by the employer to protect him against hazards and shall not take any action liable to hamper compliance with such instructions.”

“Every employer shall display detailed instructions in a conspicuous position at the work place indicating the measures to be taken to prevent fire and protect the workers against the hazards to which they may be exposed while performing their work.”

The GASCO PTW system is a key part of the measures implemented by GASCO to comply with these legal requirements.

1.2 LEGAL REQUIREMENTS

1.1 GASCO HSE POLICY



The prime objective of the GASCO PTW system is to ensure that potentially hazardous work is properly controlled and co-ordinated. It is the means of providing written instructions and authorisation to people carrying out such work.

It is a key part of the measures taken to safeguard people doing the work, others who may be affected by the work, and the facilities themselves.

It uses documents to define the work, the associated hazards and the precautions to be taken for those hazards, and includes a system of authorised signatories for the preparation of the documents.

It defines the roles and responsibilities of persons in the GASCO Organisation, and those of Contractor management, with respect to the GASCO PTW System.

1.3 OBJECTIVE OF THE PERMIT TO WORK SYSTEM



The purpose of the GASCO PTW System is to ensure that a safe working environment is achieved by providing management control over the various work activities, which may be potentially hazardous.

The PTW System provides a formal and controlled process that identifies and communicates hazards and risks associated with planned work and ensures that appropriate precautions and control measures are implemented so that the work can proceed and be completed safely.

It is important to note that a Permit to Work is not a permission to carry out hazardous work. It is an essential part of a procedure that provides instructions on how to carry out any potentially hazardous work safely and in a managed, controlled way. The PTW System has the following key features:

1.4 PURPOSE AND SCOPE

It allows personnel to be aware of the potentially hazardous activities being undertaken under PTW by providing a systematic overview. The specific arrangement for the display of Permits allows identification of potentially conflicting work tasks, both on a geographical and time basis;

It defines the controls required to prevent threats from releasing hazards during the work as well, as the recovery controls that will mitigate the effects should a hazard be released;

It sets limits to the duration and extent of the work;

It encourages formal and careful attention to safe systems of working by requiring the signature of specified individuals, who must confirm satisfactory completion of the various stages of the Permit lifecycle, viz:

o Hazard Assessment and Risk Assessment

o Precautions and Controls

o Worksite Preparations

o Handover and Handback

•

•

•

•



The GASCO PTW System requires that appropriate ‘Custodians’ within the GASCO Organisation undertake responsibility for the PTW System.

The Principle Custodian, responsible for authorising all changes to the GASCO PTW System, is the Senior Vice-President Operations, (SVP (O)).

The Custodian responsible for the development of the PTW System and the co-ordination across GASCO is the GASCO HSE Vice-President (HSE).

Custodians responsible for the implementation of the PTW System are the Plant and Pipeline Vice-Presidents (the Asset Owners).

1.5 CUSTODIANSHIP OF THE PTW SYSTEM



Deviation from the PTW System may be necessary in special circumstances, but the safety of personnel, the protection of the environment and assets must not be jeopardised. Once the situation is normalised, the PTW System must be re-applied.

If anybody involved in the PTW System is unsure of a course of action, he must consult a higher authority and not take risks.

Any planned deviations from the procedures contained in this document must be requested by the Plant or Pipeline Vice-President, in writing, to the Senior Vice-President Operations (SVP (O)).

Approved derogations will be issued as a Supplementary PTW procedure, authorised by SVP (O) and approved for issue by the Plant or Pipeline Division Manager for subsequent inclusion in Chapter 10 of the PTW System Manual.

The PTW Supplementary procedure will normally only apply to the location that has requested derogation from the procedure. The Supplementary PTW procedure will inculde a description of the deviation and the expiry and is to be issued, by the Plant or Pipeline Division Manager, to all registered holders of the PTW System Manual at that location.

During the validity period of the authorised derogation, the PTW Suppliementary procedure is to be filed in the Deviation Chapter of the PTW System Manual by each respective manual holder.

The required validity period of any PTW Supplementary procedure is to be agreed with SVP (O). Upon reaching the expiry date, unless further approval is obtained in writing from the SVP (O) for an extension to the original expiry date, the PTW Supplementary procedure is to be rescinded and copies removed by the registered holder of each controlled copy of the PTW System Procedures Manual at that location.

1.6 DEVIATIONS FROM THE PTW SYSTEM



Only controlled copies of the PTW System Manual are to be used.

The latest revision of the PTW System Manual will be available on the GASCO Intranet for all staff.

To ensure that the PTW Manuals in circulation are current the following document management procedure is to be complied with:

1.7 CONTROL OF PTW SYSTEM MANUAL

Hard copies of the PTW Manual will be circulated to registered holders only. Each copy of the PTW Manual will have a unique number and will be registered as a controlled copy.

No uncontrolled copies of Manuals, or sections of Manuals, should be made;

The PTW Manual is designed in Sections to allow easy revision and update without the need for reissue of the complete manual. Each section will have a revision number and effective issue date;

Only the register holders of the PTW Procedures Manual will be issued with updates; A transmittal note will accompany original manuals, and subsequent revisions to manuals, to each holder of the controlled copy of the manual

The holder of the controlled copy of the manual has the responsibility for:

Inserting revisions, Removing and destroying superseded pages,

Updating the history page at the front of the controlled manual;

Completing the amendment record;

Completing the return section of the transmittal note to HSE/S;

Advising all his staff who are ‘users’ of the PTW System with regard to the changes.

There must be sufficient overlap to allow proper review and discussion of all permitry on the facility.The Shift Controller is to ensure that the PCF status display boards reflect at all times the current status of Permits on the facility. There should be a formal record in the shift handover logbooks of all relevant information pertaining to permits and any worksite preparations/ de-isolations.Permits may be transferred between shifts providing the endorsement of the Permit is done. (see Chapter 5) This is a two-step process, which requires:

Where applicable, obtaining the Counter Signature of the Area Authority on the Gas Test Certificate after the initial, and any subsequent gas test;

Taking immediate steps to prevent or halt work if gas tests results are outwith the expected range, and bringing it to the attention of the Area Authority and/or the Asset Operator

CHAPTER 3


3.1 INTRODUCTION

3.2 Restricted and Unrestricted Areas

For the purposes of this Permit to Work System, work can be described as an activity that comprise one or more tasks. It is implicit that the work has been agreed as necessary, having been through the planning stage of the work management process. The Permit to Work System is concerned with authorising and managing this work.

The issue of a Permit does not, by itself, make a job safe. Those preparing for the work can only achieve that, together with those supervising and executing the work. In addition to the PTW System other precautions may need to be taken, e.g. in relation to Plant Operations and Worksite Preparation phases. All levels in the organisation must clearly understand both the PTW System and their roles within it.

GASCO facilities handle both flammable and hazardous materials. To differentiate those areas where these specific hazards exist; the GASCO PTW System requires that each Plant and Pipeline Division classify specific areas as either a Restricted Area or an Unrestricted Area. Additionally, there is a requirement to further define zones within the Restricted Areas where there is an identified Hydrogen Sulphide (H2S) hazard.

Each Plant or Pipeline Vice-President is responsible for producing a plot plan of the site or pipeline, indicating the Restricted and Unrestricted Areas and highlighting any H2S hazard zones.



3.2.1 Restricted Areas

3.2.2 Unrestricted Areas

3.2.1.1 H2S Zones

These are areas, defined by the Plant or Pipeline Vice-President, under control of the duty operations shift or pipeline operations staff, which has restrictions on the access of personnel, and which requires the application of the GASCO PTW System for defined work activities. Examples are:

These are all other areas within the Plant or Pipeline perimeter fence, which have not been defined as Restricted, and which do not normally require formal control under the PTW System.

Unrestricted (Operational) Area

An area of the plant or pipeline, under control of the duty operations shift or pipeline personnel, which does not normally require the application of the GASCO PTW System, other than for specific, identified higher risk activities The appointed Operations Asset Operator, where required, issues the Permit.

Unrestricted (Non-Operational) Area An area of the plant or pipeline, not under the control of the duty operations shift or pipeline staff, which does not normally require the application of the GASCO PTW System, other than for specific, identified higher risk activities. The appointed Asset Operator, normally Maintenance/ Engineering, where required, issues the Permit

H2S Zone An area of the operational plant or pipeline, within a restricted area, where there is, or there is potential for, high levels of H2S (>500ppm mole) to be present in the process stream. Whenever work involves breaking into the operating envelope in an H2S zone, then the area measuring 10 to 15 metres, horizontal and vertical, shall be termed the ‘H2S Sterile Area’ and persons entering this H2S sterile area shall wear a BA set and a personal monitor.

Operating areas of the Plant and thus require precautions and controls. These may, or may not, include access roads;Areas deemed to be hazardous under Hazardous Area Electrical Classification and, therefore, requiring further controls;Critical for the operation of the facility, e.g. Control Rooms and Electrical substations

(i).

(ii).

(iii).



3.3 CONTROL OF WORK WITHIN CLASSIFIED AREAS

3.3.1 Work in Restricted Areas not normally requiring a Permit

All work in a Restricted area is normally subject to full PTW System controls.It is not, however, intended that the full PTW procedures be applied to all activities.It is, therefore, sensible and practicable that work activities, for which the ActivityRisk Assessment process has shown to be of Low Risk, be permitted with a minimum of controls. Examples of work in Restricted areas not normally requiring a Permit are:

It is also permissible for Plant or Pipeline Vice-Presidents, to add to the list, for their specific location, if a risk assessment of the work shows that a Permit would not add value. The Plant or Pipeline Vice-President, must maintain a register of ‘Work in Restricted Areas not normally requiring a Permit’.

A Permit is not needed when urgent action is required to prevent/minimise/limit loss or damage of personnel or equipment, i.e. actions in emergency situations;

Normal routine activities, conducted by competent personnel, in accordance with agreed operating procedures;

Visual inspection of areas and equipment, except for confined spaces;

Operation of equipment for approved operational training activities;

Handling of non-hazardous materials;

Routine housekeeping activities inside restricted operating areas, but excepting electrical substations, where electrical engineering authorisation is required for entry;

Routine sampling of hydrocarbon products (excluding product streams containing high levels of H2S) as per approved procedures by competent laboratory staff.

3.3.2 Control of Work (requiring a Permit) in Unrestricted Areas

3.3.1.1 Control of Work (not requiring a Permit) in Restricted AreasIn order that Operations staff may be aware of people visiting RestrictedAreas, or working in Restricted Areas without a Permit, a control mechanism is required. Each site is to implement a ‘Restricted Area Access and Work Register’. Suggested outline content for the register is:

It is further recommended that the agreed list of work (as per 3.3.1), which can be undertaken without a Permit, be appended to the Restricted Area Access and Work Register, for reference purposes.

In general, work in Unrestricted Areas is not required to be subject to the PTWSystem. There will, however, be some work activities in Unrestricted Areas, which are considered to be of a higher risk, which require further controls to be applied.

3.3.1.2 Control of Work in the Vicinity of PipelinesIn Pipeline Division, 30 metres either side of a designated pipeline, or pipeline corridor, is defined as a Restricted Area. The intent is that no work may take place within 30 metres of any Pipeline containing hazardous material without GASCO PTW controls being applied.

In Pipeline Division, a specific form, the Authorisation to Work (ATW), is provided (see Chapter 5, Section 5.9). The Purpose of an ATW is to provide a process for the control of work being undertaken in the vicinity, but not directly on, GASCO pipelines by GASCO, Third Parties or Contractors, and to communicate this to other interested parties. A flowchart is provided in Appendix G to aid the Permit Originator and Permit Issuing Authorities in determining Pipeline Division PTW requirements.

3.3.2.1 Authorisation of Work in Unrestricted Areas

Work in Unrestricted Areas requiring a Permit is

Depending on circumstances, Plant or Pipeline Vice-Presidents, may require certain other work in Unrestricted areas to be subject to the PTW System. In this case a Register of such work must be maintained. As with the 'Work in Restricted Areas not normally requiring a Permit' (see 3.3.1) details are to be maintained by the Plant or Pipeline Vice-President.

In Pipeline Division, where the distance from the pipeline exceeds 30 metres, but is less than 200 metres, Third Parties and Contractors are required to advise GASCO of proposed work activities and to obtain a No Objection Certificate (NOC) prior to commencing work. After evaluating the risk, the Asset Owner decides what PTW System controls (if any) are required.

Work involving naked flame, grinding or welding (other than in defined, approved areas e.g. Maintenance Workshops);

Confined Space Entry, e.g. sewers, pits or tanks;

Activities which introduce an electrical hazard;

Excavations, which are in proximity to underground services or pipelines.

Work involving a radiographic source

Any work where a hazard requiring controls is identified by the Originator, e.g. working at heights on buildings or structures, and this list is not exhaustive.

Where work in Unrestricted Areas is subject to the PTW System, the authority for authorisation of work will normally be the Asset Holder of that particular section of the site or facility.

Where there is potential to affect Plant Operations, the Operations Shift Controller (the Asset Operator for Restricted Areas) should also countersign the Permit.

The Plant/ Pipeline Vice-President, is responsible for authorisation of the Asset Holders and Asset Operators, who will sign permity, for defined areas of the site or facility.

3.3.3 Work Requiring a Permit

3.3.4 Permits Covering more than one Work Activity

All work to be done in a Restricted Area or H2S Zone, that is not included in 3.3.1, or is in an Unrestricted Area requiring controls, then the work is subject to the PTW System.

At the discretion of the Asset Holder, a Permit may be issued to cover more than one simultaneous work activity within a designated area, subject to the following criteria:

A Risk Assessment has shown the site conditions and hazards are of a similar nature and can be covered on one Permit;

There are clear isolation/ master isolation boundaries;

The same GASCO Maintenance/ Engineering discipline or Contractor is involved, or, where considered appropriate, a lead Trade discipline has been appointed with agreed responsibilities for overseeing the work activities;

The jobs/ activities are all under the supervision of a single designated PICWS (as per (iii) above) and there is no conflict with the PICWS role as the ACCEPTOR of the Permit.

The area covered by the Permits is clearly defined on marked up drawings (and attached to the Permit) and can be adequately supervised by one person;

In general, the PICWS should have clear line of sight to all activities undertaken under a single Permit, and have adequate access to, and communication with all persons involved in the activities.

Gas tests, where required by the Permit, must be carried out as appropriate to cover all activities within the designated area. The results are to be recorded on the Gas Test Certificate (see Chapter 5, Section 5.2). If any measurement is outside permissible levels, then the Permit must be suspended and, if necessary, separate Permits issued.

(ii).

(iii).

(iv).

(v).

(vi).

(vii).



3.3.5 Work which requires Interface Procedures

Typically, no more than four simultaneous activities, which meet the aforementioned criteria, should be included on a Permit that is under the supervision of a single PICWS. In special circumstances, the Asset Owner may give dispensation to deviate from this standard, e.g. during major Plant shutdowns, where the Plant is positively isolated and declared free of hazardous and flammable materials, and it is deemed reasonable to expand the work under the control of a single PICWS.

Interface procedures apply whenever there is a risk of interference or mutual risk between two parties working within close vicinity of each other. They exist to ensure that all parties are aware of each others activities and that the risks and potential hazardous interactions have been jointly identified and communicated, and that satisfactory control measure have also been jointly identified and implemented to allow the work activity to continue safely.

PTW Interface procedures (see 3.3.5.1 to 3.3.5.5) apply for all work being undertaken within the following designated interface areas:

Within 30m of the boundary between two different GASCO Area Authorities who are responsible for a section of the plant within the responsibility of the same Asset Operator;

Within 30m of the boundary between two different GASCO Asset Operators, e.g. Habshan Plant/ Facility having different Shift Controllers;

Within 30m of an ADNOC Group Company administered area, facility or pipeline;

Where the work is conducted within the designated boundary of an ADNOC Group Company facility, pipeline corridor or administered area by GASCO or GASCO contractors;

Where the work is conducted within the designated boundary of an GASCO administered area, facility or pipeline corridor by an ADNOC group company or their contractors;

Where the work is conducted within the designated boundary of a shared PTWInterface Area by GASCO, or by GASCO contractors.

NB. A shared PTW interface area is one that is jointly administered by both GASCO and another ADNOC Group Company (such as the Joint Pipeline Corridor).

(vi).



3.3.5.1 Interface Procedures between Asset Operators/ Area Authorities

3.3.5.2 Interface Procedures for ADCO working within GASCO Controlled Areas

Any hot work being conducted within 30 metres of the boundary between two separate Areas (Habshan) requires the countersignature of the adjacent Asset Operator (the Area Shift Controller) as well as that counter endorsement (initial) of the adjacent Area Authority.

For hot work being conducted within 30 metres of the boundary between two distinct areas within a defined Plant or facility, having different Area Authorities, e.g. between two separate Process Trains, the counter endorsement (initial) of the adjacent Area Authority is required.

Work by ADCO within GASCO controlled Areas, or within 30 metres of GASCO Pipelines, requires the use of the GASCO PTW System.

The GASCO Asset Owner (the Plant or Pipeline Vice-President,) should have an updated list, from the ADCO Division Manager, of ADCO personnel who are Authorised signatories under the GASCO PTW System having satisfied GASCO Competency requirements.

Prior to work commencing, the Issuing Authority (Asset Operator) is to jointly visit and check the work site with the ADCO Authority to confirm that all work site precautions required by both Authorities are in place.

The GASCO Permit must be referenced to any ADCO Permit which has been issued, and which is related to the same work activity. In such cases, the GASCO Authority is to countersign the Issue Section of the ADCO Permit or Hot Permit.

The ADCO Authority is to countersign the Issue Section of the GASCO Permit and any supporting Hot Work Permit(s).



3.3.5.3 Interface Procedures for GASCO working within ADCO Controlled Areas

3.3.5.4 Interface Procedures for Working in Shared PTW Interface Areas

All personnel who have to enter areas under ADCO control for monitoring or checking their equipment must obtain permission from the relevant ADCO Area Authority. Where GASCO has to work in ADCO controlled areas, either on their existing plant, on ADCO plant or new construction, they must first obtain an ADCO PTW.

The ADCO Permit request must be signed and submitted by a GASCO Permit Originator. The GASCO Permit Originator must meet the equivalent job grade criteria (minimum supervisory Grade 11) as required by ADCO PTW procedure. The GASCO Permit Originator must be authorised on a written list submitted to the relevant ADCO Area Manager by the respective GASCO Asset Owner (the Plant or Pipeline Vice President) to request work to be undertaken within ADCO controlled areas.

Prior to work commencing, the ADCO PTW Procedure requires the ADCO Issuing Authority to jointly visit and check the work site with the GASCO Authority to confirm that all work site precautions required by both Authorities are in place. The GASCO Authority (the Asset Operator) is to countersign the Issue Section of the ADCO Permit or Hot Permit.

The ADCO Permit must be referenced to any GASCO Permit which has been issued, and which is related to the same work activity. In such cases, the ADCO Authority is to countersign the Issue Section of the Work Permit or Hot Work Permit.

Shared PTW Interface Areas of GASCO and another ADNOC Group Company, are those areas specifically designated on maps/ drawings where both Companies have plant and/ or equipment and where neither Company has overall responsibility. In general, these areas are commonly where flowlines and pipeline are in close vicinity to each other or cross (see Appendix A).



3.3.5.4 Interface Procedures for Working in Shared PTW Interface Areas (Cont.)

3.3.5.5 Requirements for Identification of PTW Interface Areas with ADCO

Interface procedures also apply to the Joint Pipeline Corridors when working in the vicinity of ADCO, GASCO or ADNOC pipelines. Joint Pipeline Corridors will be bounded by an area 30m either side of the outmost pipelines.

Within a Shared PTW Interface Areas, including the Joint Pipeline Corridor, the PTW system of the Company undertaking the work will apply, i.e. if GASCO, or GASCO contractors, are working a GASCO PTW will be required; if another ADNOC Group Company is working then their PTW will be required.

In all cases the work activity and PTW must be discussed with the Asset Operator of the other ADNOC Company (in ADCO the Area Authority) sharing the area before the work commences. The other ADNOC company’s Asset Operator must countersign the PTW prior to issue. All Permit Signatories authorised to sign/ countersign PTW, within Joint PTW Interface Areas, must be authorised by the Asset Owner (the Plant or Pipeline Vice-President,). This is to be on a written list submitted to the other ADNOC company’s equivalent Asset Owner (in ADCO, the Area Manager).

Work in the Ruwais Easement Areas is under the control of TAKREER

All areas within ADCO’s concession area are designated ADCO administered areas, except for those areas specifically agreed and marked up on approved drawings. ADCO PTW procedures and requirements apply for all parties working within ADCO administered areas.

Drawings clearly detailing the agreed designated boundaries of ADCO, other ADNOC Group Company PTW administered areas, and agreed PTW Interface Areas as specifically referred to in this section must be available for all sites.

A simplified layout drawing, depicting GASCO/ ADCO PTW Interface areas is included as a reference in Appendix A at the end of this Chapter.



3.4 RISK MANAGEMENT PROCESS FOR WORK

3.4.1 Introduction to the Activity Risk Assessment (ARA) Process.

There are, in general, three types of work activity:

In all cases, the initial Risk Assessment should be undertaken prior to the origination of the Work Permit and any supporting Permits or Certificates (see Chapter 5). It is the responsibility of the Maintenance/ Engineering Authority to initiate the process and record the Risk Assessment An overview of the risk assessment process for work activities, and its application within the PTW System is provided in flowchart form in Appendix B at the end of this section.

The following sections describe, for each of these types of activities, the steps that must be taken in order to ensure the integrity of the risk assessment process.

Whenever work has to be undertaken by GASCO, Third Parties or Contractors on GASCO sites, or in the immediate vicinity of GASCO pipelines, it is necessary to make a suitable and sufficient assessment of the risks to the health and safety of employees and others, for the purpose of identifying the necessary control measures. Practically this involves four basic steps, which are to:

Work activities that have had a Risk Assessment previously completed and recorded in procedures or in Maximo;

Work activities that are new or have not been risk assessed, and

Work activities that can be covered by individual’s competence, skills and training.

•

Identify the possible hazards associated with the work activity;

Assess the consequences of the hazardous event(s) and the likelihood of their happening, i.e. evaluating the risks arising from them;

Introduce control measures (precautions) to prevent or reduce the risks to a level ‘As Low As Reasonably Practicable’ (ALARP). See 3.4.1.3 for further explanation and guidance on demonstrating ALARP;

Specify recovery measures in case the controls fail.

•

•

•



3.4.1.1 Assessing the Risks

The process of identifying the hazards, evaluating risks and applying controls and specifying any recovery measures will be referred to as ‘Activity Risk Assessment’ (ARA). This is shown diagrammatically in Fig. 3.4/1 below.

In practice, these steps are not always distinct and many decisions about the overall process will be taken as part of the Activity Risk Assessment. Completing the four steps of the ARA will produce risk reduction measures that both prevent incidents, by reducing the probability of occurrence, and mitigate chronic and acute effects by reducing the consequences.

Assessing risk involves considering how likely it is that each hazard could cause harm, by considering the threats which may lead to the release of the hazard, what the consequences could be, and, in some cases, the potential for the event to escalate.

The extent of any risk assessment will depend on the nature of the risks, the complexity associated with the activity, and on whether the risks are well understood. The ARA in the workplace can be as basic as deciding how to go about doing a task safely for simple routine jobs.

GASCO has developed a Risk Assessment Matrix (RAM) as a tool to help categorise the risk, based on its consequences and the probability of the potential consequence occurring (see Appendix C).

3.4.1.2 Controlling the Risks

Figure 3.4/ 2 - Degree of Control versus Initial Risk

Controlling risk involves eliminating the hazard wherever possible, or applying measures to prevent the hazardous event and/or the harm from happening.

In all cases, the extent of any risk assessment and the controls arising from it should be proportionate to the risks. The higher the risk, the greater the degree of control required and the more senior the management level required to approve the activity.

Figure 3.4/ 2 below illustrates that, as the risk increases, the necessary level of control for the activity can be achieved by adding controls or by strengthening existing ones.

As the risk increases, a documented risk assessment is required and the competency and skills may need to be strengthened and/or a procedure implemented.

At higher levels of risk, Permit to Work Controls will be required. Ultimately, Senior Management Authority will be necessary (see 3.4.5).

3.4.1.3 Demonstrating ALARPALARP means to reduce a risk to a level, which is as low as reasonably practicable. This involves balancing reduction in risk against the time, trouble, difficulty and cost of achieving it. This level (ALARP) represents the point, objectively assessed, at which the time, trouble, difficulty and cost of further reduction measures becomes disproportionate to the additional risk reduction obtained.

A key concept in identifying the ALARP level is to ensure that all possible options for risk reduction have been identified. It is often the case that only the obvious or easy options are considered. It is important, however, to look at all options even if at first they appear difficult or costly.

The Risk Assessment Matrix (RAM), (see Appendix C) is a tool that provides a standard approach to the qualitative assessment of risk. All activities, which fall in the yellow (medium) or red (high) sectors of the RAM, require documented evidence that they have been reduced to ALARP. An Activity Risk Assessment (ARA) form is provided for this purpose (see Appendix E).

Specific guidance on the completion of the ARA form is given in 3.4.3, Stage 6, and Appendix D.



3.4.2 Performing an ARA for Previously Assessed Activities

3.4.3 Performing a New Activity Risk Assessment

Most activities that are undertaken are not new, they are routine, or common tasks that have previously been risk assessed and/ or are covered by existing procedures. They have probably been developed through established good practice and with due consideration for the hazards that may be present.

Such activities do not need a new risk assessment each time they are carried out, but do require that the assessment is subject to periodic review, primarily to identify if anything has changed that would affect the outcome of the assessment.

Some questions, which should be asked, are, for example:

If new controls are identified then the Permit Originator should update the ARA and the date of the review should be recorded.

This section describes the steps required to perform a risk assessment for an activity, or combination of concurrent activities, which have not been previously assessed. This process should also be used if a previously assessed routine or common task has been reviewed and the risk assessment found to be not appropriate for the particular job.

When a new risk assessment is performed, all hazards and threats should be identified and the risk assessed such that controls can be identified to reduce the risk to ALARP (see 3.4.1.3). If the risk cannot be reduced to ALARP, the activity should be redefined or not undertaken.

Have the persons doing the activity changed and are any new persons competent?

Have new hazards been introduced?

Are new tools being used or new procedures introduced?

•

3.4.3 Performing a New Activity Risk Assessment (Cont.)Stage 1: The Originator will Identify and form the ARA Team.

The ARA is normally conducted within the Department responsible for doing the activity and should include personnel who are:

Stage 2. Identify the Hazards and Effects.

Each task is to be studied to identify the hazards, hazardous events and potential incidents whether they arise from the actions of people or from the conditions surrounding the activity.

The assessment should identify who or what might be harmed and the findings recorded.

Stage 3. Identifying Risk Ratings for Initial Risks

Risk rating is a means whereby the risks associated with a particular hazard or hazardous activity can be expressed as a value and compared with acceptable limits.

The initial risk rating should be assessed on the situation that prevails before any controls are implemented for each hazard. The Risk Assessment Matrix (see Appendix C) should be used to calculate risk ratings.

The ARA should be undertaken prior to origination of the permitry. Where appropriate, the team should visit the worksite. The activity can be broken down into a number of smaller tasks where it is considered necessary.

Responsible for the task;

Competent to conduct an ARA;

Have sufficient knowledge, expertise and competence in the activity to be performed to have an understanding of the hazards it presents;

Knowledgeable about the location, and the hazards that are present;

To be Involved in carrying out the task.

•

•

•

•

•



Stage 4. Identify Control and Recovery Measures.

Taking each hazard in turn, the ARA team should develop ways to either, eliminate the hazard or provide appropriate control and recovery measures to mitigate them. In practice, a mixture of different controls often produces effective control, e.g. engineering controls, personnel protective equipment and procedures.

Stage 5 Review Residual Risks.

The residual risk is any risk that remains after all the control measures are applied. The Risk Assessment Matrix (RAM) should again be used and the results entered in the ARA Worksheet. The residual risk should be ALARP (see 3.4.1.3).

Stage 6 Document and Record.

The ARA should be recorded using the ARA Worksheet. A copy of the ARAWorksheet is included in the Appendices (see Appendix E). An annotated version of the ARA is also provided in Appendix D, which provides guidance on its completion.

The ARA Worksheet can be used to:

Communicate the outcome and actions to those responsible for implementing the control measures and performing the activity

Ensure the information is available to others who may have to perform the activity.

It is recognised that some low risk activities are adequately covered by the competency and skills of the individual. Therefore, where a formal risk assessment would not produce any significant findings it is not necessary to formally record the risk assessment.

3.4.4 Activities covered by Individuals Competence



3.4.5 Responsibility for ARA process

3.4.6 Linking the ARA and the Permit to Work

STEP 1 Work Description and Risk Assessment

The Plant and Pipeline Vice-Presidents are responsible in their respective areas for the ARA process as described in 3.4.1. In addition, for certain activities, they are personally responsible for approving the ARA where there is a higher level of initial risk, such as, (though not exhaustive):

This section should be read in conjunction with the Work Permit (see Chapter 5, Section 5.1, Fig. 5.1).

A matrix diagram, which provides an overview of the Work Permit Lifecycle versus Signatory Responsibilities, is provided in Appendix F.

Before work commences following the ARA, authorisation must be obtained through the Permit to Work system by issuing a Work Permit together with any necessary supporting documentation.

The Work Permit has a number of consecutive steps that are all part of the overall Risk Management process and are in addition to the ARA. These steps are as follows:

Following completion of the ARA, the person who is requesting the work, the Originator, has to describe what work is to be done and what equipment is to be used. The work scope must be clearly defined in order that the persons undertaking the worksite preparations are clear as to the intent.

The results of the ARA are also recorded on the Permit in terms of the hazards associated with the work and the controls necessary during its execution. Where the work activity covers several tasks, or is of a more complex nature requiring sequential controls, with different persons responsible for individual tasks, an Activity Sequence Control Sheet (ASC) should be completed (see

Hot tapping on live hydrocarbon process streams

Disjointing and/ or spading on live flare lines or lines containing H2S

Confined space entry in oxygen deficient or toxic atmospheres

Heavy lifting operations over live hydrocarbon process lines

It is the responsibility of the Area Superintendent to bring such high-risk activities to the notice of the Plant/Pipeline Vice President

•

•

•

•



Continuous attendance of the PICWS, with signed transfer of responsibility when one PICWS is replaced by another. Work MUST stop when no PICWS is present. The PICWS is not to hold any other Permit whilst nominated as a Category A, PICWS presence.

A Hot Work - Category 1, Permit and other designated high-risk jobs(e.g. Vessel Entry) would normally require a Category A presence.

As Category A, but work may continue during short (e.g. not more than 45 minutes) absence of the PICWS. One person cannot be responsible for more than one Permit when nominated as a Category B, PICWS presence, unless the other Permit is in close proximity to the first one and can be safely supervised by one person.

The PICWS is to make an initial visit, and is then required to make only periodic visits to the worksite. The number of Permits, with a Category C PICWS presence, which can be held by one PICWS, should be limited to a maximum of six and is further dependent on the PICWS ability to provide adequate supervision for all Permits under his control.

As a guideline, each worksite should be visited by the PICWS at least three times during a shift/ normal work period.

The holding of several Category C Permits and one Category B Permit is permissible providing the rules for Category B are satisfied

Chapter 6) and submitted with the permitry.

One of the controls to be specified is the requirement for the supervision of the work, defined as the Person in Charge of the Worksite (PICWS). The level of supervision (the category of worksite presence required) should be appropriate to the risk of the job being undertaken.

The category of worksite presence is defined as follows:

Category A:

Category B:

Category C:



STEP 1 Work Description and Risk Assessment (Cont.)

Supporting documentation may also be originated at the same time as the Permit because the Risk Assessment Process (ARA) may also have identified particular hazards introduced by the work, which require further formal controls. Examples are:

Where such risks are identified, then Supporting Permits or Certificates are needed. These are listed in Table 3.4/ 1 for specific activities and provide the mechanism for defining the controls required.

Illustrations of all Permits and Supporting Certificates are given in Chapter 5, Figure 5.1 to Figure 5.8.

STEP 2 Permit Review and Validation

DAILY PTW MEETING*

Objective:

3.4.6 Linking the ARA and the Permit to Work (Cont.)

Following the origination stage of the Permit, it is necessary to present the Permit to Operations (the Asset Operator) so that agreement can be reached with respect to the timing of the work. This is normally done at the daily Permit to Work meeting.

This PTW meeting is the forum for Maintenance/ Engineering and Operations to review all new permitry submitted for work that has been agreed as necessary in the Maintenance/ Engineering Work Plan. It is here that any risk assessment which has been previously undertaken (as described under 3.4.1) and which requires submission of a formal Activity Risk Assessment sheet is discussed, and further elements of the overall Risk Management process are developed. Because of the importance of this daily PTW meeting it is described here in more detail.

At weekends, or where permitry is not submitted via the daily PTW Meeting, the Asset Operator and Authorised Maintenance/ Engineering Authority must undertake the process of reviewing and validating of permitry.

To provide a daily overview of all ongoing and planned work under the control of the Permit to Work System and to identify any potential conflicting activities.

For Operations to review and agree new Permits, including any Activity Risk Assessments previously undertaken, time scales and resource requirements.

Note that the daily PTW meeting is not the forum for undertaking the ARA.

To provide an effective handover mechanism to duty shift teams through the recording of work that is to be undertaken in the Operations Area.

To provide a Maintenance/ Engineering and Operations interface for Permit to Work requirements.

(i)

(ii)

(iii)

(iv)



As a minimum, the daily PTW Meeting will be attended, by the Operations Coordinator, who will normally be the Chair Person, Shift Controller (as available) and appointed Maintenance / Engineering staff.

Further attendees, for example Technical Support and/ or HSE, will be present if requested by the Operations or Maintenance/ Engineering attendees, when it is recognised that further expertise or advice is relevant.

A check must be made to ensure that there is no foreseen conflict, both geographically (i.e. across other work boundaries) or on a time basis (activities which may start later). This is to be done by the Asset Operator.

Once the permitry has been discussed at the daily PTW Meeting and controls agreed, the Permit can be VALIDATED, that is, accepted by the Asset Operator as an agreed piece of work that has been risk assessed and is to be undertaken in an area controlled by Operations (or for Unrestricted Areas the appointed Asset Operator).

* Pipelines Division may hold the meeting at a lesser frequency, as workload requires but not less than weekly

The meeting will be held daily, taking into account weekend working.

Key input mechanisms to the daily PTW Meeting will be work details/ status of ongoing work and any new activities. Any preparatory requirements for new activities should be highlighted.

As far as is possible/ practicable, all new Permits should be processed through the daily PTW meeting, unless it is HSE or production critical and cannot wait. In such cases, Permits may be processed outside of the PTW Meeting, but the Maintenance/ Engineering Authority and the Asset Operator must still adhere to the same review and validation process.

Permitry must be submitted with adequate advance warning to allow Operations the required timescale for detailing and recording of isolation procedures and for equipment preparation.

STEP 3 Permit Issue

STEP 4 Permit Acceptance


When the worksite preparations are complete, and any additional Permits/ Certificates prepared, the final stage of the authorisation process can take place, that is, the ISSUING of the Permit.

It is important to note, however, that although the Permit is issued, work may not start until all of the necessary Permits are accepted and endorsed (see Steps 4 & 5).

The person responsible for the work activity ACCEPTS the Permit. This is the Person who will be, or will hand over to, the Person In Charge of the Work Site (PICWS) and he must arrange any necessary Toolbox Talk(s).

The Toolbox Talk is the last step in the Risk Management process and is the final opportunity to discuss the hazards and controls with the persons who will execute the work. Generally speaking, a Toolbox Talk is required for all activities undertaken under a Permit, although for routine, lower risk, activities need not necessarily be formally recorded.

Guidance notes on undertaking Toolbox Talks is given in Chapter 7, which includes an example of a Toolbox Talk record sheet.



The PICWS must now sign the Permit to demonstrate that he understands the hazards of the work and the controls necessary. He has the responsibility for making sure everyone in the work party understands his particular role in the work, and that they understand the relevant hazards and the required controls. Should the PICWS change, or there be more than one PICWS, e.g. if there are different shift teams, the same criteria of accepting responsibility apply.

The Maintenance/ Engineering Authority, who has accepted the Permit, must take it to the worksite and obtain the endorsement of the Area Authority that it is safe for the work to start. This is a control as it gives the Area Authority the opportunity for a further discussion of the work and to identify any activities in the area, which may conflict with the work.

The Permit is then endorsed by the PICWS, who accepts responsibility for the worksite prior to work start, and is the final opportunity to discuss the work prior to its commencing.

Once all parties have initialled for work start, the Permit is now ENDORSED.

When work has stopped at the worksite, normally at the end of the Maintenance/ Engineering work period, this is recorded on the Permit by the PICWS. Once the PICWS has initialled for Work Stop, the Permit is termed as SUSPENDED.

STEP 7 Permit Closure

6.3 Permit Re-endorsement

3.4.7 Visibility of Permits

At the start of each new shift, a further re-endorsement is required by:

When work has been completed, or requires Permit renewal, the CLOSURE portion of the Permit must be completed.

In particular, when work has been completed or will lapse for an extended period, but isolations must remain in force, it is important that the controls associated with the isolations remain valid. Such controls must be visibly continued and displayed in the PCF.

Once the PICWS has initialled the Closure portion of the Permit it is now termed as CLOSED.

The Asset Operator to confirm there is no conflict with any other activity;

The Area Authority to confirm that there is no change to worksite conditions;

The PICWS to accept responsibility for the continued safety of the worksite.

As part of the Risk Management process, Permits must be displayed in a systematic arrangement, clearly showing work in progress or work suspended, for each defined Operating Area. The display should be at a suitable Permit Control Facility (PCF) (see Chapter 8). Management and Operations staff can therefore readily see the activity status for all work subject to the PTW system.

Included in Chapter 8, Appendix A is a simplified flowchart showing the various stages in the Permit lifecycle and how the continued safety of the worksite is managed and administered.

References should be made to Permit and Supporting Certificate examples, Chapter 5, Figure 5.1 through to Figure 5.8.

The Work Permit is designed as a double A4 format to provide a sequencing of signatures as the Permit passes through its various stages.

The Work Permit is the core the PTW System and is the only Permit which can be 'stand-alone'.

Supporting Permits and Certificates are designed to identify specific hazards and controls, additional to those recorded on the Work Permit. A Work Permit MUST accompany all supporting Permits and Certificates.

For visibility purposes, and to aid identification of documents, different colours are used on the border of Permits and Certificates as per Table 3.4/ 2 below.

The key steps of Validating, Issuing, Accepting and Endorsing of Permits is done by Persons who have been assessed as competent to execute the Risk Management Process associated with these separate steps.

Certain activities, namely those that require supporting Permits, have a higher level of risk and consequently higher levels of authorisation exist.

Permit Signatories are those who have had sufficient training and experience and have been duly authorised as those Permit Signatories by Plant and Pipeline Vice-President.

The Authorised Signatories, who are responsible for signing the various sections of the Work Permit and Supporting Permits or Certificates, are tabulated in Table 3.4/ 3.

The Work Permit and the Supporting Permit or Certificates are printed to allow 2 copies for display purposes as follows:

To ensure that precautions required for tasks of a long duration are reviewed regularly, limits are set on the validity periods that Authorised Permit Signatories may set for Permits. These are:

Work Permits..................................... 7 consecutive (calendar) days.

Hot Work Permit, Category 1 & 2…… 7 consecutive (calendar) days

Radiation Permits............................... 24 hours

Isolation Confirmation Certificate....... No Validity period

Excavation Permit.............................. 28 consecutive (calendar) days

Confined Space Entry Certificates… 28 consecutive (calendar) days

Gas Test Certificate………………… No Validity period

Pipeline Authorisation to Work (ATW)… 28 consecutive (calendar) days (max. extension of 3 x 28 days)

The maximum endorsement period for Permits, supporting Permits and Certificates is 12 hours. An endorsement may not straddle an Operations Shift change. Where a shorter endorsement period is required, a statement in the 'Particular Hazards and Additional Precautions' section of the Permit should indicate where this is required.

Pipeline ATW Forms have endorsement periods but are subject to worksite checks by the Area Authority on a frequency defined by the Asset Operator (see Chapter 5, Section 5.9.4).

In normal circumstances, there should be a sensible limit on the maximum number no of Permits to be administered and issued by the Asset Operator and each Area Authority on a shift basis. Guidelines for the maximum number of Permits are given in Table 3.5/ 1 below. Preferably, the number of Permits should be managed below these recommended figures.

The recommendation covers only the numbers of Work Permits and Hot Work Permits to be managed, and does not take account of any other supporting Permits or Certificates issued.

In other circumstances, e.g. during major shutdowns when Permit requirements are greater, special arrangements for the control and administration of Permits should be made and agreed with the Plant or Pipeline Division Manager.

At the daily PTW meeting, the Asset Operator should review the current number of Permits per operational area prior to accepting new Permits. Any increase beyond these criteria should first ensure that the quality control, safety and individual responsibility is not compromised.

All work is to cease immediately on initiation of any Plant alarm or advised change of Plant status away from normal by the Area Authority or Asset Operator.

On the re-establishment of normal status, the PICWS is to obtain the verbal authorisation of the Area Authority before restarting work except where there has been an escape of H2S when the Permits issued in H2S zones must be re-endorsed.

For Hot Work activities, or where there has been an escape of H2S, the PICWS is to return the Hot Permit to the Permit Control Facility for subsequent re-endorsement of the Asset Operator before restarting work.



If changes are required to the work details on any Permit prior to the Work Permit validation, the Originator must initial them. If changes are required after the Work Permit validation, they are to be initialled by the Originator and the Validating Authorities (the Asset Operator and Authorised Maintenance/ Engineering Authority).

Precautions and controls may be added to, but not deleted from, a Permit. These should be agreed with the Validating and Issuing Authorities prior to making changes on the Permit details. All Permit signatories must then initial against the agreed changes.

HOW TO USE THE RISK ASSESSMENT MATRIX (RAM) 1. Assess the POTENTIAL CONSEQUENCES of the hazard for each of the four categories (People, Assets, Environment, Reputation)2. Assess the PROBABILITY of these POTENTIAL CONSEQUENCES occurring for each of the four categories (People, Assets, Environment,

Reputation) 3. Classify the risk on the matrix for each of the four categories (People, Assets, Environment, Reputation) from the intersection of the chosen row

(POTENTIAL CONSEQUENCES) with the chosen column ( PROBABILITY) 4. In order to document the risk classification, first record the PROBABILITY (A - E), then the POTENTIAL CONSEQUENCES (1 - 5), and finally the

category to which the classification applies (People = P, Assets = A, Environment = E, Reputation = R ), for example C3P. 5. Based on the risk classification, identify and implement appropriate remedial action for each of the four categories (People, Assets, Environment,

Reputation) as indicated below: • LOW risk – manage for continuous improvement • MEDIUM risk – demonstrate that the risk is at a level that is as low as reasonably practicable (ALARP) • HIGH risk – take action to reduce the risk to a level that is as low as reasonably practicable (ALARP)

CHAPTER 4


4.1 INTRODUCTION

4.2 STANDARD OF ISOLATION

4.2.1 Isolation Requirements

Once the hazards associated with a particular job have been identified, it will be necessary to consider how they can be separated or isolated from the equipment or plant to be worked on. Flammable, toxic, pressurised, high temperature, or low temperature fluids will normally have to be removed from the isolated plant before working on it.An essential ingredient of any Safe System of Work is the integrity of the isolation procedure. Whilst the Work Permit identifies the isolation requirements it does not provide the specific isolation details. These are to be documented and appended to Permits as per existing, Plant specific, Isolation and re-instatement procedures.All sites must ensure that the latter are controlled in accordance with specified standards. These should be in compliance with the following.

In general, Plants are built with isolation provisions an integral part of the design (for example, DGS-0000-020) with the basic premise that the isolations prevent leakage. In case this premise in practice is not confirmed additional controls are required to manage risk to As Low As Reasonably PracticableThere are two main methods of isolation:

Positive isolation. There are specific situations where positive isolation is required such as Confined Space Entry and Hot Work with a Naked Flame. This means incorporating the use of spades, spectacle blinds, or removable spools and blind flanges. Spades and blinds must be fully rated; use of thin blinds must be with site management approval. Positive isolations must be at the closest point possible to the work.

a)

Valved isolation Under less hazardous situations a valved isolation may be applied:i) Double Block and Bleed. • Breaking of the hydrocarbon or toxic gas envelope should be against a double block and bleed with the tightness of the isolation confirmed by testing. Residual pressure must be zero at the work location.

b)



4.2.2 Establishment of Isolation Boundaries

4.2.3 Control of Equipment Preparation

4.2.4 Documentation of Isolations

The Operations Superintendent is responsible for ensuring that a comprehensive suite of documented procedures is in place, which define the mechanical (process) system isolations for all plant and equipment.The Maintenance Superintendent is responsible for ensuring a comprehensive suite of documented procedures is in place, which define the electrical and instrument Isolation boundaries for plant equipment.The Shift Controller is responsible for the authorisation of the isolation of equipment to be worked on, and any action necessary to prepare the equipment for safe working, such as de-pressurising or purging. He is also responsible for the authorisation of de-isolations on completion of work.

The preparation and isolation / de-isolation of equipment can introduce particular hazards. The Shift Controller must ensure that controls are in place to manage the risks associated with these hazards at each step of the preparation, isolation and de-isolation process.

4.2.4.1 Mechanical and Instrument Isolations

Where isolations form part of the preparations for work, there must be a clear description of the isolation procedure, including a detailed list of all items (e.g. valves, spades, blinds, pipework removed, blank flanges fitted, vents and drains opened, breakers racked out, etc.), utilised in the isolation. These are to be documented on the Isolation Confirmation Certificate

When work is to be undertaken which requires isolation of equipment a formal written scheme of isolation must be prepared with isolations documented on the Isolation Confirmation Certificate The isolations must provide control of all hazardous energy sources within the defined system and/or equipment isolation boundaries including electrical power, process fluids, hydraulic, pneumatic, thermal, chemical and mechanical systems. Where appropriate (e.g. where there are no tag numbers or where the isolation is complex), a P&ID showing the isolations must accompany the isolation procedure.

• If the breaking of the hydrocarbon or toxic gas envelope has to be done against a single isolation valve a risk assessment is required involving as a minimum Superintendent level. Tightness of the isolation must be confirmed by testing and if not 100% tight, additional barriers are required.ii) Single valve isolations • Single valve isolations may be used for less hazardous materials e.g. water and nitrogen.



Where appropriate (e.g. where there are no tag numbers or where the isolation is complex), a P&ID showing the isolations must accompany the isolation procedure.The Isolation Confirmation Certificate together with any P&IDs used to show isolations, must be kept in the PCF with the copies of the relevant Work Permits.Any changes to the isolation procedure or isolation boundaries are to be approved and initialled, after the relevant section of the procedure, by the Maintenance/ Engineering Authority and the Shift Controller. This should be done prior to making any change in the isolation.

The document for recording electrical isolation and de-isolation operations, for the purpose of the PTW System, shall be the Isolation Confirmation Certificate. (See Chapter 5, Section 5.7) The use of any Sub-Station/ Switching Logs and Switching Programmes required for by the Electrical Safety Rules, to record isolations and de-isolations, are additional to the PTW System requirement.

The only exception to the rule that specifies the need for an Electrical Isolation on an Isolation Confirmation Certificate to be raised is when an electrical isolation is required for low voltage (<50 volts) electrical work. An Electrical Person, having the required level of competence, may carry this out providing he has been duly authorized by the Senior Electrical Engineer to undertake this type of work.

A Master Isolation may be used to establish isolation boundaries for major tasks, which encompass more than one process system and/or piece of equipment. This is so that a number of tasks can be undertaken within a single boundary. Recommended standards for controlling work under A Master Isolations are as follows:(i) Each Master Isolation Boundary should be clearly defined in a written procedure. The specific isolation details covered in the procedure should indicate the isolated and de-isolated position of each isolation device and the equipment and/ or system affected.

4.2.4.2 Electrical Isolations

4.2.5 Master Isolations



4.2.6 Minor Mechanical Isolations

4.3 PHYSICAL SECURING AND TAGGING OF ISOLATIONS

4.3.1 Requirements for Securing Valve Isolations

The recording of isolation details is not mandatory for Small Bore Instrument Mechanical Isolations carried out by an Instrument Person, assessed to the required level of competence, provided ALL the following conditions are met:

The Operations Co-ordinator has the responsibility for approving this procedure. Final authorisation for its use rests with the Operations Superintendent.(ii) Control of the Permits in use within the boundary is to be maintained by the Shift Controller.(iii) When a Master Isolation is in place, the Shift Controller is to ensure that all Permits in use within the boundary have been closed out before the Master Isolation integrity is compromised, i.e. prior to allowing any de-isolations to be undertaken.

Valves require to be immobilised in such a manner that they cannot be inadvertently operated. In this case the interference with the isolation will be immediately obvious.

The work is minor routine maintenance work, i.e. work that is considered to present no more risk than that associated with achieving a physical isolation;

A Work Permit exists to cover the work, endorsed by the Shift Controller and Area Operator;

The isolations are listed on a suitable document to the satisfaction of theShift Controller;

The isolations are of such a minor nature that they will not degrade the integrity of any Safety/ Emergency System;

The work to be done under the isolation will be undertaken by the person who applied the isolation, who will not leave the worksite whilst the isolation is in place. If the isolation is to remain in place beyond a single shift, then the isolation details must be recorded and the isolation points secured and labelled.

The isolation does not form part of an isolation boundary for other work;

4.3.1.1 Immobilising Devices

4.3.1.2 Securing, Locking and Tagging

a) Securing

b) Locking

c) Isolation Tagging

a)

b)

The range of valves fitted on GASCO facilities would require a number of different methods of Immobilisation. Some valves may already have fixed, immobilising devices fitted, e.g. Castell Locks, Ellis Locks, etc. As it is not practical to provide such devices for all valves, the recommended method is to use simple securing mechanisms with locking and tagging.

Multi part labels, as shown below, are to be utilized to identify isolation and break points. Each Vice President for Plant and Pipelines is responsible for developing detailed procedures for the labels.

A tamper-proof seal to be used to lock the securing mechanism or where appropriate to directly lock the immobilizing device in position is the nylon Grip Rip seal

A visible Isolation Tag (see Fig.1) is to be used for valve isolations which is:

Red in colour printed with a unique number on each of 3 parts part so that the stubs and counterfoils can be kept with isolation details in the PCF when the label is attached to the isolation point.

d) Fitted with large secure eyelet to enable the sealing device to fit through it, thus making it an integral part of the securing arrangement.

e) Identified with the Work Permit number related to the isolation, and the Labels own unique serial number on all the three parts of the label.

Valves and other isolation devices required to be physically secured in such a manner that they cannot be inadvertently operated without destroying the securing mechanisms (e.g. chain and lock arrangements). The preferred method is to use Red and white high strength polycarbonate chain. This has good visibility, is easily handled and secured, and is sufficiently strong to provide adequate integrity of the isolation.

Made up of material which cannot be torn off easily.

c) Capable of being written on with a permanent marker.



Spades, spectacle blinds and blanks will be identified by a similar design label, but Yellow in colour (see Fig.2).

Figure: 1

!



Spade and Blank insertion is generally the preparatory activity for other work and is identified in the approved Method Statement supporting a Work Permit and Isolation Confirmation Certificate To assist in the identification of spading points, and to identify the spacers that may be removed when a spade is fitted; a blue spade location tag is attached to the spading point at the planning stage (see FIG.3). When the spade is fitted, the Blue tag is attached to the removed spacer. This ensures the spacer is refitted into correct location. Spade location tags do not have stub and counterfoil portions.

All flanges/joints above 10” that have been ‘broken’ by Maintenance Department are required to be torqued /tensioned. These are to be positively identified in order to record the location, re-instatement and final pressure testing of the joint.

Operations will maintain a ‘Joint Broken’ register in the to control room and record compliance to these requirements. A unique 3-part, multi-colored, Joint Assembly Tag, is to be utilized for this purpose (see Fig.4)

4.3.1.3 Common IsolationsWhere a single valve is used as isolation for more than one isolation boundary, a tag label relating to each Work Permit is to be applied to the device. In this situation the securing device fitted SHALL NOT be removed until the last isolation label applicable to the valve or spade is removed.

4.4 LOSS OF ISOLATION RECORDSWhere isolation is found with some, or all, of its documentation missing, an investigation will be required before the isolation can be removed. The following procedure should be followed:

The Shift Controller is to double-check the Permit, in the PCF and the archive for the relevant documentation;

The Area Authority is to carry out an onsite check of the system against a P&ID for any other isolations, for valves not in their normal operating position, or breaks/open ends in the system;

(i)

(ii)



4.5 EXTENDED PERIOD ISOLATIONS

Extended Period Isolations (EPI's) are isolations, which are required to remain in place although no work is being carried out within their boundary. They may be required for two main reasons

Where work has commenced but is, or is likely to be, suspended for a period exceeding the validity period of the Work Permit, for example, when awaiting spares for a repair;

Where an item of equipment becomes redundant and is to be isolated pending a Plant Change Proposal to remove it or provide a more permanent means of isolation.

(i)

(ii)

4.5.1 Documenting of EPI's

The procedure for the documenting of EPI’s is as follows:

The Shift Controller is to record the EPI in an EPI Register in the PCF. The white copies of the Work Permit and the Electrical Isolation Certificate and/ or other isolation details are to be retained in the EPI section of the Permit Rack in the PCF.

When it becomes possible for work to restart within the EPI boundary the Originator is to raise a new Work Permit. The isolation details are then to be attached to the new Work Permit, and handled by the Originator in the normal manner.

The Shift Controller will record the fact that the EPI has been cancelled in the EPI Register.

COMPLETION OF THE WORK PERMIT, SUPPORTING PERMITS ANDCERTIFICATES

5.1 COMPLETION OF THE WORK PERMIT

5.1.1 Work Description and Risk Assessment

Box 1a. Identification of the Task and its location

The work order number should be entered into the space provided

Box 1b.

This procedure should be read whilst referring to the Work Permit (see Chapter 5, Figure 5.1). The responsibilities of the Permit of Work Signatories are explained in Chapter 2, Section 2.2.

An overview of the task so that is easily visible from the Work Permit’s slot position in the Permit display rack, and the date that the Work Permit is required;

Permit Originator is to enter:

The Originator enters the Location/ Tag number and Area/ Worksite in order to clearly identify the equipment and area where the work is to take place. The Originator ticks the Boxes relevant for the Area (and if he does not know, then the Asset operator will tick the boxes).

Box 2 Work Description and Equipment

The Originator is to describe the work in summary form but containing sufficient detail so that appropriate worksite preparations can be made. Any special equipment to be used, especially where it may introduce a threat or hazard, is to be entered. Reference may be made to engineering method statements and if this is the case the engineering method statement should be attached to the Permit.

•



Box 3 Particular Hazards and Special Precautions

Box 4 Worksite Supporting Documents

Box 4a

When the Originator undertakes the Activity Risk Assessment (ARA) process and subsequently the review with the Validator, hazards may be identified that require to be highlighted on the Work Permit. Provision is made for this in Box 3.

Whenever a protective function is being disabled or a Safety/ Emergency system being isolated, it is mandatory to enter in Box 3 the controls necessary to prevent escalation should a hazard be released.

The Originator will also enter the category of worksite presence by the PICWS, after agreement with the Asset Operator during the PTW Planning Meeting. This is a worksite control.

The Originator enters the reference number of any supporting Permits or Certificates required as a result of the ARA process These supporting documents will accompany the Work Permit when presented to the daily PTW meeting, or, where the work is of an urgent unplanned nature, directly to the Asset Operator.

Box 4b The Originator enters the reference number of any related Work Permits including the Trade that the related Work Permit has been issued to. Where the Work Permit is a continuation then the previous Work Permit reference number is also entered.

Box 4c The Originator is to tick the relevant Boxes for any other supporting documentation that is to be submitted with the Permit.

Box 5 Specific HSE Requirements

The Originator will tick the relevant Boxes in the ‘required’ column of Box 5 thus indicating the HSE equipment/ resources necessary as precautions for the work. These will have been identified during the Activity Risk Assessment step



Box 6 Work Permit Originator

Box 7 Worksite Preparations

Box 8

5.1.2 Permit Review and Validation

The Originator completes Box to signify the end of the origination steps.It should be noted, however, that the subsequent Permit review, Validation and Issue steps might identify a need to add to Boxes 3, 4 or 5. If this is the case, the Originator must initial any such change to signify that he is aware of them and accepts them.

When the Work Permit is presented to Operations, the Asset Operator (Operations Co ordinator or his deputy) will decide what preparation and isolations are to be made on the equipment (refer to Chapter 4, Worksite Preparations) and tick the required Box.

When the preparation is complete the Area Operator or Assistant Shift controller will initial the check Box.

In the case of Protective Function Disable or Safety Systems isolations, the Asset Operator ticks the requirement in Box 7. The Shift Controller records the detail in the Trip and Safety System Defeat Register, which is held in the Main Control Room, when the protective function is disabled.

The Maintenance/ Engineering Authority completes Box 8. When more than one Maintenance/ Engineering Authority is involved, the Maintenance/ Engineering Authority who signs does so on behalf of the others and assumes overall responsibility for the permitry aspects.

Box 9 The Asset Operator (the Operations Co-ordinator or Shift Controller) completes Box 9. This validation step is normally completed at the Permit Planning Meeting when the Activity Risk Assessment (ARA) is reviewed. The Asset Operator then sends the Validated Work Permits to the PCF for display in the Validation slot of the display rack.



5.1.3 Permit Issue by Operations

5.1.4 Permit Acceptance by Maintenance/Engineering Authority

5.1.5 Worksite Responsibility

Box 10

Box 11

Once it is confirmed that:

(i). The worksite preparations are complete, and

(ii). There is no conflict with any other Work Permit or work activity.

The Shift Controller completes Box 10.

(If the work requires any type of isolations, then ICC certificate must be completed prior permit issue).

When the work involves an interface activity (defined in Chapter 3, Section 3.3.5) or the work involves a higher degree of risk (see Chapter 3, Section 3.4.3) then a countersignature is required, by the other Asset Operator or the Asset Holder, in the space provided in Box 10.

The Maintenance/ Engineering Authority accepts the Permit from the Shift Controller and completes Box 11.

Box 12 The Maintenance/ Engineering Authority will enter the name of the Person in Charge of the Worksite (PICWS) in Box 12(a). The PICWS will sign to acknowledge he understands his responsibilities after Area Authority endorsement at the worksite.

Normally the PICWS will remain in charge for the duration of the job, but to cater for a change in the designated PICWS, extra spaces are provided in Box 12(b). Also if there is more than one designated PICWS, e.g. to cater for shift working, then the name of the additional PICWS should be entered in Box 12(b). In both cases the PICWS must sign Box 12(b).



Box 13

Box 13 Shift Handovers:

Further Endorsements:

5.1.6 Endorsement for the Continued Safety of the worksite

The Maintenance/ Engineering Authority will take the top (white) copy to the worksite for endorsements in Box 13 by the Area Operator and PICWS. The PICWS will display the Permit at the worksite. (Note for Pipelines the endorsement may take place in the PCF)

The 2nd (yellow) copy is retained in the Permit Control Facility and visibly displayed by the Shift Controller, or Assistant Shift Controller, in a slot in the Endorsed section of the display rack.

At the end of the Engineering work period, the PICWS initials the space in Box 13 (Work Stop) on the top (white) copy displayed at the worksite to state that work has stopped. The PICWS takes the top (white) copy to the Maintenance/ Engineering Authority for return to the Permit Control Facility.

The original and the copy are now brought together by the Operations Shift Co-ordinator and placed in a slot in the Suspended section of the PCF display rack, with the white top (white) copy uppermost. This allows Operations Department to gain an overview of Suspended Permits and the following days commitments.

When a shift change occurs within an Engineering work period (e.g. 8 hour shifts) the work must stop until both the oncoming Asset Operator and Area Authority have endorsed the Work Permit prior to endorsement of the PICWS

Where work has to continue on the following day the Asset Operator will again check for conflict and approve the work continuation by initialing Box 13. The top (white) copy is then issued at the Permit Control Facility to the Maintenance/ Engineering Authority, who again takes it to the worksite for endorsements as described above



5.1.7 Permit Closure

5.1.8 Archiving

Box 14a When the work is completed, the PICWS will initial the space provided in Box 14a and take the copy to the Maintenance/ Engineering Authority. The Maintenance/ Engineering Authority takes the copy to the Permit Control Facility and completes Box 14a.

Box 14b The Area Authority will confirm the worksite conditions and initial the space in Box 14b for the worksite.

The Asset Operator completes Box 14b, including the statements on isolations.

Box 15a If the work is not completed, the PICWS will initial the space provided in Box 15a and take the top copy to the Maintenance/ Engineering Authority. The Maintenance/Engineering Authority takes the copy to the PCF and completes Box 15a indicating the work status.

Box 15b If the Maintenance/ Engineering authority has indicated in Box 15a that the worksite has been cleared the Area authority will confirm the fact and sign Box 15b. The Asset Operator then completes Box 15b.

After close-out, the Asset Operator is to file the original (white) copy of all Permits, together with the top copies of any supporting Permits or Certificates, as per archiving requirements (see Chapter 8).



5.2 COMPLETION OF THE GAS TEST CERTIFICATE

5.2.1 Archiving

This Section should be read whilst referring to the Gas Test Certificate (See Chapter 5, Figure 5.2).

If not specified by the Operations Co-ordinator at the Daily PTW meeting, the Shift Controller should complete the Gas Test Certificate sections, relating to:

After close out the Gas Test Certificate will be automatically archived with the Work Permit

The results of the gas test will be entered on to the Gas Test Certificate which is on the backside of the Work Permit, at the worksite, by the Authorised Gas Tester, and (if the Area Operator is not undertaking the gas test) advise the Area Authority of the result.

If the Area Authority is not undertaking the gas testing, then he must initial the Certificate in the space provided to show he is aware of the test result(s).

For higher risk activities, such as Confined Space Entry and Hot Work-Category 1, the Issuing Authority is to witness the initial gas test prior to the issue of the supporting Permit or Certificate.

Subsequent gas test results, as stipulated in the Test Frequency requirements section, are to be recorded in the Additional Gas Test Record Section.

The Gas Testing Requirements;

The Test Frequency;

The gas or gases to be tested for Worksite Certification.

CHAPTER 6


6.1 OBJECTIVE

The Activity Sequence Control (ASC) form provides a useful tool in the PTW System for work that involves several stages, or is complex, by allowing the work to be described in a stepwise sequence, whereby:

• the hazards are identified for each work activity

• the controls to mitigate the associated risks are defined

• the responsible parties at each stage are identified

The use of an ASC is recommended whenever a Work Permit covers more than one work activity (see Chapter 3, Section 3.3.4), which requires clear identification of boundaries of responsibility, e.g. more than one Trade discipline is involved.

6.2 Use of ASC in the Permit to Work System

The ASC is not intended to be a substitute for a Maintenance/ Engineering Method Statement, but more a sequential listing of tasks so that hazard identification and application of controls is structured. In particular, it provides a control mechanism should any stage of the work require a signature of approval before proceeding to the next stage.

An annotated version of the ASC, which provides guidelines for its completion, is given in Figure 6.1.

A blank copy of the ASC Form is provided in Figure 6.2.

6.2.1 Responsibility for Identifying the Need for an ASC

The Activity Risk Assessment (ARA) team will normally be responsible for identifying the need for, and the writing of an ASC (see Chapter 3, Section 3.4.2). An ASC will normally be presented with the Permit at the PTW

planning meeting for review and discussion, and is to be cross-referenced in Box 4c of the Work Permit. Where incorporated, it is to be included in the Toolbox Talks associated with the work.

CHAPTER 7

TOOLBOX TALKS

7.1 INTRODUCTION

This Section supports the Activity Risk Assessment Process described in Chapter 3, Section 3.4 and should be read whilst referring to the Work Permit (Chapter 5, Figure 5.1).

One of the last steps in the Activity Risk Assessment (ARA) Process is to discuss the Work Permit, and any supporting Permits or Certificates, with the persons who will actually be carrying out the work, and therefore be directly exposed to possible release of hazards. This is achieved by holding a 'Toolbox Talk '.

Toolbox Talks are an essential element of safe working practices in GASCO’s sites for both GASCO and contractor staff. The purpose of the talk is to discuss with the working party:

• What the work activities will be; • What hazards have been identified that will require controls during the course of the work; • What those controls are and how the work party will be affected.

The work party may, by virtue of their experience identify further hazards or may be able to suggest alternative, or improved, controls. Where this is the case, the hazards and additional precautions section of the Permit should, if necessary, be modified and initialled after consultation and agreement with the validating and issuing authorities.

The Originator of the Permit should formally capture this feedback by updating the ARA, which can then be utilised the next time the work is undertaken.



7.1.1 Deciding on the need for a Toolbox Talk

The requirement for a Toolbox Talk will be decided by the Permit Originator, based on his judgement of the risks involved and the work party’s experience and familiarity with the task.

A formal Toolbox Talk is not normally required for routine jobs, covered by maintenance procedures, which are carried out by competent staff and which are undertaken frequently.

If the job is unusual, complex, is done infrequently, or, is being done by new persons then a formal Toolbox Talk is required. The Toolbox Talk need not cover all of the work at the same time. The Toolbox Talks may be given at different stages of the job and should, where applicable, be linked to the Activ-ity Sequence Control Form (ASC).

7.1.1.1 Checklist for identifying the need for a Toolbox Talk

To help the Originator decide if a formal Toolbox Talk is required guidance is given in the matrix below

Work AspectAre there any Inexperienced (work experienced) Membersin the Work Party?Is the Task unfamiliar to the Work Party?Is the Work Site unfamiliar to the Work Party?Is the Work Scope of a complex nature?

Is Multi-Trade Co-ordination required?Is the Task HSE Critical?Is the Task Operationally Critical?Are hazards, or potential hazards, present?Has there been any change to Work Scope?Can Adverse Weather Conditions affect the Task?Are Operations or Specialist Personnel to bepresent?

If the answer to all questions is NO, a formal Tool Box talk is not required.

Yes No



7.1.2 Format of the Toolbox Talk Where there is a perceived higher risk, the Permit Originator should stipulate the

requirement for a formal record of the Toolbox Talk. In such cases, the Toolbox Talk is to be recorded on the Toolbox Talk Record Form on the back of the PTW

The Toolbox Talk Record Form provides an effective communication means for ensuring the work party are:

• Aware of the work scope; • Aware of the hazards; • Knowledgeable as to the methods/ procedures to be adopted; • Aware of the PTW precautions/ controls; • Aware of any constraints; • Aware of what tools and equipment are to be used; • Aware of Environmental considerations; • Aware of any potentially conflicting activities; • Able to clarify any issues and provide comments.

Where included, the Toolbox Talk Record Form should be cross-referenced by ticking the box in Section 4c of the Work Permit.



7.1.3 The Presenter of the Toolbox Talk

The presenter of the Toolbox Talk(s) is to be agreed at the Daily PTW Meeting. It is normally the person who knows most about the job. Depending on the circumstances, it may be more than one person. For example, an Operations person rather than an Engineering member of staff can better describe hazards that may arise from Operations.

All members of the work party must indicate that they understand the Toolbox Talk. Where different nationalities are involved, it may be necessary to appoint an additional person who is conversant in that language, to assist the presenter in the talk, in order to overcome any language barriers or literacy issues.

The Toolbox Talk should be repeated if: (i). The work party changes or new personnel are assigned to the work party; (ii). Circumstances, or conditions, relating to the work activity change; (iii). The work enters a different phase.



7.1.4 Checklist for the Toolbox Talk Presenter After giving the Toolbox Talk, the Presenter should confirm the understanding of

the Work Party by using the following checklist as an aide-memoir:

Can all the personnel in the Work Group answer YES to the following questions?

� Are all members of the work party aware of the hazards involved with the work activity?

� Are all members of the work party aware of the control measures required to mitigate the risks associated with the hazards?

� Are those people in the work party who are responsible for implementing these control measures aware of their responsibilities?

� Are these control measures in place?

� Is everyone aware of what is being done at the worksite?

� Is the work party aware of what everyone else is doing at the worksite?

� Is there other work ongoing in close vicinity to the worksite, which the work party need to be aware of?

� Does the Person in Charge of the Worksite (PICWS) know an additional Toolbox Talk is required should there be any significant change to the work scope?

� Does the PICWS understand the requirement to provide a Toolbox Talk to any new people joining the work party?

� Are there any Language/ Literacy Issues?

� Does everyone know what to do in the event of a site alarm or emergency?

If the answer to any of these questions is NO, then the safety of people is at risk and must be addressed.

CHAPTER 8

PERMIT CONTROL FACILITY AND ADMINISTRATION OF THE PTW SYSTEM

8.1 OBJECTIVE

A fundamental requirement of any PTW System is that it provides a suitable display of permitry on the facility, in a central location, to allow staff an overview of current status. It is also required that all closed out permitry be archived in a systematic fashion for easy reference and follow-up auditing purposes.

This section contains the detailed procedure for the handling of Work Permits, supporting Permits and Certificates, and other related documents as they pass between signatories and are administered through the Permit Control Facility (PCF).

8.1.1 Permit Control Facility Requirements

8.1.1.1 Purpose of the Permit Control Facility

The Permit Control Facility (PCF) will be provided in a central point of the Plant or Pipeline facility through which all Permits pass each time their status changes, i.e. when Authorised, Endorsed, Suspended or Closed.

This enables a check to be made that the work specified does not conflict with any ongoing Permit work. It also allows a continuous display of work in progress to be maintained.

It can, in addition, provide the venue for the daily Permit-to-Work (PTW) meeting whereby all work requirements will be discussed and agreed.



8.1.1.2 Layout and Location of the PCF

The size and layout of the PCF will depend upon the complexity and configuration of the facility. For a small and less complex facility it may be a

section of the Control Room, whilst for a more complex facility, if space permits, it may merit a separate room.

The PCF should ideally be located in, or in close proximity to, the Control Room or other central facility. Where this is impractical, the location should be selected carefully to ensure that it is readily accessible to users, and will not cause excessive additional journeys for personnel obtaining signatures.

A PCF has to be of sufficient size to house, in one location, all the information displays boards, permit racks, and all the relevant files and data

that are required to be stored, for the Asset under the authority and control of the Asset Operator. Where there is more than one Asset, with several Asset Operators (e.g. Habshan), it is permissible to have separate PCF

facilities, providing the Shift Superintendent (the Asset Holder) can maintain an overview.

Within the PCF, there should be physical separation between the occupants and the customers so that only nominated personnel can alter the displayed data.



8.1.1.3 Facilities Within the PCF

Permit Rack: As a minimum, there are to be conventional racks for the display of paper copies of all Permits from all departments on the Plant or Pipeline.

It is to be arranged in such a way that Permit location and status are readily visible. This enables staff to readily check which equipment is under

maintenance and is not available for operation.

Permit Location Board: Ideally, there should be a plan of all areas and units of the facility showing, as appropriate, the Hazardous Areas in correct geographical orientation. The location of all Permit work in progress can be indicated with suitable markers, together with safety system inhibits and the position of barriers and scaffolding work.

Firemain and Fire & Gas System Schematic Diagrams: It is useful for schematic diagrams of the Firemain and Fire & Gas System network to be

displayed in the PCF. These can be arranged in such a way that equipment for maintenance or repair can be indicated in a highly visible manner. This provides an indication of fire and safety systems not available for operation.

Desk and Counter Arrangement: This should be arranged to suit the configuration of the PCF. It is recommended that it provide physical separation

between the customers and the Issuing Authority. This will allow the customers visibility of the information displayed whilst ensuring that only authorised personnel can alter the displayed data.

The Shift Controller, who is the Asset Operator responsible for shift operations, will manage the PCF. The Assistant Shift Controller may assist him but there must be clear understanding as to their individual roles and responsibilities, when changing Permit status and updating displays, to avoid potential conflict situations arising.



8.1.2 PCF - Principles of Operation

In the PCF, for each asset under the control of the Asset Operator (Shift Controller), all Permits and systems isolation boundaries will be systematically

displayed in one location, so that operators can readily see and check which equipment is isolated for maintenance and not available for operation.

At the PCF, staff will be able to obtain key information to aid their decisions with respect to Permits and the isolating and de-isolations of equipment. Data displayed will cover the whole facility.

The facilities of the PCF are to be available throughout periods when work is in progress on the Plant. When unattended, the PCF should be secured to

maintain the integrity of the information it contains.

8.1.3 Review and Control of Work under PTW

No work under a Permit is to be commenced until that Permit has been reviewed by the Asset Operator (Shift Controller) to give confirmation that:

(1) The work does not clash with that being undertaken under the authority of any other Permit or isolation.

(2) The Authorised Signatory is correct for the category of work and that the Permit is correctly filled in.

No isolation or De-isolation is to be started until the appropriate isolation/deisolation details are documented and agreed by the Shift Controller.

The Shift Controller should confirm that the proposed isolation boundary is compatible with any other isolation boundaries in force under the PTW System.

Only when the above has been properly completed may the Permit be issued.

All Suspended and Closed Permits are to be displayed separately from those Endorsed and Validated in the PCF Permit Display Racks.



8.1.4 Segregation of Permits in Permit Display Racks

The Permit Control Facility (PCF) is to provide a Permit Rack system, suitable for the display of permitry, sub-divided by Area of the Plant or Pipeline facility.

The Permit Rack arrangement should allow for the further segregation and visual presentation of permitry status within the following sections (see also diagrammatic representation, Figure 8.1):

VALIDATED Section

After validation, by the Maintenance/ Engineering Authority and the Asset Operator (normally the Operations Co-ordinator), the Work Permit, together with its additional supporting certificates are placed in the 'VALIDATED' section of the Permit Display Rack.

Operations staff is now aware that planned work in the Operations area has been approved but has not yet started.

The Shift Controller shall, prior to arranging for any worksite preparations, check the Permit against other Permits displayed in the PCF for conflicting activities. If any conflicts are identified, he is to advise the Originator and Operations Co-ordinator who will agree either to:

a) Withdraw the new Work Permit, or,

b) Arrange for other Permits to be Suspended or Cancelled, dependent upon relative priorities.

Once this step is completed the Shift Controller may authorise Worksite preparations to proceed. He is to ensure that any other supporting documentation

(e.g. isolation/ blind lists) is retained in the Permit Rack along with the associated permitry.



8.1.4 Segregation of Permits in Permit Display Racks (cont.)

ENDORSED Section

When the worksite preparations and checks for conflict are complete, the permit is issued by the Asset Operator (Shift Controller) and accepted by the Maintenance/Engineering Authority who then takes the top, original (white) copy to the worksite for Area Endorsement.

The 2nd (yellow) is transferred to the 'ENDORSED' section of the Permit Display Rack

Operations staff is now aware that the planned work is actually proceeding in the Operations Area.

At the start of each new shift period, prior to each subsequent endorsement of the Work Permit, the Asset Operator will again check for conflict with any other Work Permit or ongoing activity prior to releasing the Permit.

NB. It is permissible for the Assistant Shift Controller to carry out subsequent endorsements of permitry on the agreement of the Shift Controller who is the principle Asset Operator.

SUSPENDED Section

At the end of the Maintenance/ Engineering work period the original top copy, is returned to the PCF and, together with the other copy, is transferred to the

'SUSPENDED' section of the Permit Display Rack. The permitry is to be arranged with the top original (white) copy on top.

Operations staff are now aware that work which was in progress will/ has been suspended but is to continue and isolations will/may be in place.

In the event of the Maintenance/Engineering Authority not returning permitry for re-endorsement at the end of a shift period, the Asset Operator (Shift Controller or Assistant Shift Controller) should change the display to SUSPENDED. As the yellow copy will be displayed (instead of the white), it will be evident to the

incoming Asset Operator that action must be taken to follow-up with the responsible Maintenance/Engineering Authority.



CLOSED Section

When work has been completed, or a new permit is required, all the permitry is transferred to the ‘CLOSED’ section of the Permit Display Rack.

Operations staff is now aware that the work is completed or requires new permitry.

Prior to arranging for any de-isolations of equipment, the Shift Controller is to check that de-isolations will not conflict with any other Work Permit or work activity in progress.

NB. The permitry can be archived only once it is confirmed that all de-isolations are complete.

8.1.5 PTW Administration and Document Control

8.1.5.1 Permit Return

The persons working under the PTW (the Accepting Authorities) should have no direct access to Permit Display Racks. Only the Shift Controller (or his nominated Assistant) may alter permit displays.

To provide a workable system for the return of completed, or suspended, permits at the end of the working period, or on completion of the job, it is recommended to provide a tray system in the PCF.

The tray system should have (as a minimum) two trays to accept the return of all original permitry:

• One for CLOSED - for completed and/or expired Permits out with validity periods.

• One for SUSPENDED - where work is to continue.

The Shift Controller (or his assistant) will then transfer them to, and update, the Permit Display racks.

Closed permitry is to remain in the CLOSED section of the rack until it is confirmed that the worksite conditions are as stated and, where applicable, de-isolations have been completed and equipment returned to normal status.



8.1.5.2 Archiving of Permitry

All permitry is to be archived, by Area, in the PCF, or other adjoining facility, which has a controlled access. The retention period for all permitry is 6 months from the date of closure.

The recommended method of filing is to have a short term (monthly) archive and long term (6-monthly) archive system. Closed out Permits are placed by the dayshift Shift Controller into the short-term archive for later filing in the long-term archive.

The long-term archive will have all Permits archived by month and area. Each month the short-term archive contents will be transferred to the long-term archive, replacing all permitry from the first month of the preceding 6-month period. Such permitry removed from the Archive is to be destroyed.

HSE Division will prepare an Annual Programme of PTW System operation checks (one per site). The programme will:

• Confirm that the level 1 audit programmes are being maintained;

• Confirm lateral learning is being maximised between sites in the review of RAP's;

• Identify areas for improvement on sites and/ or the PTW System arising from RAP's.

HSE is responsible for:

• Preparing an overview report at the end of the Level-2 programme and submitting to SVP (O)

• Producing any Remedial Action Plan resulting from the Level 2 audit.



9.4 AUDITING OF PTW TRAINING COURSES

9.4.1 Types of PTW Training Course Audits

There are to be three PTW courses:

(1) User.

(2) Permit Signatories.

(3) PICWS

The Plant or Pipeline Vice-President is responsible for ensuring a comprehensive training programme is in place (see Chapter 2)

9.4.2 Scope of PTW Training Course Audits

The audit provides a mechanism for ensuring that the Training Standards are maintained across all courses. At least one audit of each course should be conducted every year. The Plant or Pipeline Vice President has the responsibility for ensuring the Audit of Training is carried out.

9.5 PTW SYSTEM REVIEW PROCEDURE

9.5.1 Introduction

The PTW System is subject to continuous reassessment and regular review.

Though there will be information collated throughout the year, it is required that no more than one amendment is issued per year (unless operational reasons demand otherwise). The amendment needs to obtain the same authorisation/approval level as the original PTW System Manual.



9.5.2 Contributing Sources for the Review Mechanism

Information for incorporation in the review will come from the following sources:

(1) Proposals for Change.

(2) Audit Reports.

(3) Incident Reports.

(4) PTW training course feedback.

(5) Feedback from GASCO and Contractor Personnel.

All information from whatever source must be submitted in the form of a Change Proposal (see 9.8) to enable it to be incorporated in the review mechanism.

When the VP-HSE believes that sufficient changes to the PTW System have been agreed to warrant it, he will request SVP (O) to authorise the issue of an amendment to all controlled copies of the PTW System manuals.

9.5.3 Annual Review of Gasco PTW System

Proposals for changes to the PTW System Manual and/or procedures therein should be submitted, in writing, by the respective Plant or Pipeline Vice President, to the HSE custodian for initial review and approval. Any subsequent amendments may then be authorised for issue by SVP (O), if urgent, or, where not urgent, incorporated as part of the annual review process.

There will be a formal annual review of the PTW System, and its operation, led by the HSE Vice President. This review will encompass but will not necessarily be limited to:

• Incidents relating to PTW violations and non-compliances;

• Level 1 and Level 2 Audit results;

• The review of proposals for change to the PTW System;

• All deviations applied for;

• Lateral learning opportunities from the Industry and sharing of Best Practice.



9.6 PROPOSALS FOR CHANGE TO THE PTW SYSTEM

Proposals for change or improvement to the PTW System and/or Manual can be made at any time. The proposal should be raised and documented on the

standard PTW

System Change Proposal Form (see Fig. 9.1). This is to be discussed, agreed and countersigned by the Plant or Pipeline Vice-President before being forwarded to the HSE Vice-President. The HSE Superintendent will keep a copy of the Change Proposal on location for reference purposes

The HSE Vice-President will review such proposals on a regular basis. Approved proposals will be incorporated in the Annual review of the PTW System Manual.

Originators will receive notification of the action taken on their proposal or reasons for rejection.
