1. PURPOSE The purpose of this Electrical Management procedure is to establish the minimum requirements for

the management of risks associated with the electrical works at CIP workplaces.

2. SCOPE The scope of this Electrical Safety procedure applies to all low voltage electrical activities that

involves electrical installation work as defined in WHS legislation. This procedure does not apply for

communications, data, telephone and extra low voltage systems however personnel performing these

works should be made aware of this procedure due to interface with electrical installations. This

procedure does not apply to high voltage electrical work which is to be conducted by specialist

electrical contractor in accordance with the requirements of respective state/territory Electricity

Regulator and Electricity Supply Authorities.

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 4 OF 24

3.2.7. Tiger tails are plastic pipe type cable covers, used to provide a useful visual indication to

people working in the vicinity of overhead electric lines or stay wires. Tiger tails do not

insulate wires.

3.2.8. Isolated means separated from all possible sources of electrical energy and rendered

incapable of being energised unintentionally.

3.2.9. Hostile operating environment is a ‘hostile operating environment’ is a term used to

describe an environment where electrical equipment is exposed to operating conditions

that are likely to result in damage to the equipment or a reduction in its expected life

span. This includes conditions that involve exposing the electrical equipment to moisture,

heat, vibration, mechanical damage, corrosive chemicals and dust. Examples include

wet or dusty areas, outdoors, workplaces that use corrosive substances, welding,

brazing, etc.

3.3. Procedure

3.3.1. This procedure aims to ensure that:

3.3.1.1. Risks to health and safety associated with the general electrical safety at

workplace and electrical work are identified and managed before the work

commences having regard to all relevant matters including:

▪ The risk to a person of death, shock or other injury caused directly or

indirectly by electricity;

▪ Contact with exposed live parts causing electric shock and burns (for example exposed leads or other electrical equipment coming into contact with metal surfaces such as metal flooring or roofs);

▪ Faults which could cause fires;

▪ Fire or explosion where electricity could be the source of ignition in a

potentially flammable or explosive atmosphere (for example working in

confined space);

▪ Work in harsh conditions e.g. outdoors, construction site, wet surroundings,

cramped spaces with earthed metalwork e.g. steelwork etc;

▪ electric shock from ‘step-and-touch’ potentials;

▪ toxic gases causing illness or death. Burning and arcing associated with

electrical equipment may release various gases and contaminants; and

▪ Use of portable electrical equipment which are particularly liable to damage.

3.3.1.2. Measures are taken to eliminate, minimise or control risks before, during and after

the performance of the electrical work as per Section 7 Site Specific Risk

Management System and Section 10 Safe Work Method Statements of the Site

Safety Management Plan.

3.3.1.3. Appropriate controls in line with the hierarchy of control are identified, put in place

and documented.

3.3.1.4. The site services plan is progressively updated as the services are installed in the

ground and is communicated to relevant workers on site to ensure they are aware

of the status of the in ground electrical services.

3.3.1.5. Training is provided to all relevant personnel in this procedure, SWMS and any

authority permit who are involved in the electrical work and a record of any

licences and training is maintained.

3.3.2. Examples of electrical specific injuries include:

3.3.2.1. Even the briefest contact with electricity at 50 volts for alternating current (V a.c.)

or 120 volts for direct current V d.c. can have serious consequences to a person’s

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 5 OF 24

health and safety. High voltage shocks involving more than 1000 V a.c. or 1500 V

d.c. can cause contact burns and damage to internal organs.

3.3.2.2. Electric shocks from faulty electrical equipment may also lead to related injuries,

including falls from ladders, scaffolds or other elevated work platforms. Other

injuries or illnesses may include muscle spasms, palpitations, nausea, vomiting,

collapse and unconsciousness.

3.3.2.3. Workers using electricity may not be the only ones at risk—faulty electrical

equipment and poor electrical installations can lead to fires that may also cause

death or injury to others.

3.4. Risk Management

3.4.1. The following risk factors associated with carrying out electrical work should be

considered:

3.4.1.1. sources of electrical risks, including energy levels at the workplace

3.4.1.2. the nature of the electrical work to be carried out

3.4.1.3. potential or actual high fault current levels (i.e. risks associated with arc flash)

3.4.1.4. availability of isolation points

3.4.1.5. work practices

3.4.1.6. the type of plant, machinery and equipment to be used

3.4.1.7. availability of suitable test instruments

3.4.1.8. availability of properly rated PPE

3.4.1.9. the workplace and working environment, for example:

▪ wet weather conditions

▪ in and around trenches, pits and underground ducts

▪ ladders, scaffolds, portable pole platforms, elevating work platforms, poles

and towers

▪ confined spaces

▪ ability to safely rescue persons

3.4.1.10. the competence of people carrying out the work, noting that licensing requirements

may apply for the electrical work under local electrical safety laws.

3.4.2. Also consider individual workers’ needs, for example:

3.4.2.1. Is the worker experienced in, and have they been properly trained for, the working

conditions?

3.4.2.2. Is the worker physically fit for the proposed work, for example are they able to

climb to heights to work on an overhead conductor or are they mentally alert and

not fatigued?

3.4.2.3. Does the worker have a visual or hearing impairment, for example do they have a

visual colour deficiency or hearing loss?

3.4.2.4. Does the worker take any medication that may increase their vulnerability to work

in electrical environments?

3.4.2.5. Is the worker working excessively long hours?

3.4.2.6. Does the worker suffer from claustrophobia?

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 6 OF 24

3.4.3. Risk controls should be implemented to eliminate, so far as is reasonably practicable,

identified risks to health and safety. If it is not reasonably practicable to eliminate risks,

risk controls should be selected in descending order from the Hierarchy of Control, and in

accordance with the Section 7 of Site Safety Management Plan.

3.4.4. Note: The WHS Regulations prohibit energised electrical work and the requirements of

this procedure must be followed for any testing and commissioning activities.

3.5. Common electrical risk control measures

3.5.1. Common measures to control electrical risks at CIP workplaces include:

3.5.1.1. ensuring only appropriately licensed or registered electricians carry out electrical

work

3.5.1.2. providing safe and suitable electrical equipment for example not using leads and

tools in damp or wet conditions unless they are specially designed for those

conditions

3.5.1.3. inspecting leads for damage before use and removing any that are damaged from

the workplace.

3.5.1.4. providing enough socket outlets—overloading socket outlets by using adaptors

can cause fires

3.5.1.5. ensuring power circuits are protected by the appropriate rated fuse or circuit

breaker to prevent overloading

3.5.1.6. if the circuit keeps overloading—not increasing the fuse rating as this creates a fire

risk due to overheating

3.5.1.7. encourage use of battery powered tools instead of mains operated where possible

3.5.1.8. so far as is reasonably practicable arranging electrical leads so they will not be

damaged:

▪ not running leads across the floor or ground, through doorways and over

sharp edges

▪ using lead stands or insulated cable hangers to keep leads off the ground

▪ using cable protection ramps or covers to protect cables and cords, where

applicable

3.5.1.9. using Residual Current Devices (RCDs) (also known as ‘safety switches’) to

protect workers using portable equipment as required by the WHS Regulations.

3.5.1.10. determining the reason why an RCD, circuit breaker or other over current

protective device disconnected the electricity before it is switched back on.

3.5.1.11. ensuring RCDs are effective by regular testing. All RCDs shall be millisecond

tested and tagged by a licenced electrician monthly and recorded on the site

electrical register.

3.5.1.12. ensuring all switchboard enclosures are fitted with a clear Perspex sheet

located on the front of the panel upon opening of the switchboard doors.

NOTE: The Perspex panel shall be removable with four screws located in each

corner with cut-outs for access to circuit breakers switches. The purpose of this

panel is to ensure that on opening the switch board, all switch gear and live

components cannot be accessed unless the Perspex panel is removed. The

Perspex should not be removed at any time while testing. The only time the

Perspex may be removed is when the power has been turned off at the source.

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 7 OF 24

3.5.1.13. carrying out preventative maintenance, inspection and testing on electrical

equipment as appropriate for example an appropriate system of visual inspection

and where necessary, testing. Inspection and testing of electrical equipment must

be performed in accordance with AS/NZS 3760.

3.5.1.14. Ensuring unsafe electrical equipment at workplace is disconnected (or isolated)

from its electricity supply and, once disconnected, is not reconnected until it is

repaired or tested and found to be safe or is replace or permanently removed from

use. Any repairs and testing of unsafe electrical equipment is completed by a

competent person.

3.5.1.15. Ensuring that in addition to regular testing, electrical equipment will also be tested

after repair or service that could affect electrical safety of the equipment and

before its first use if bought second-hand.

3.6. Consultation

3.6.1. The CIP Site Manager will ensure that consultation occurs with workers and their

representatives and other PCBUs where their duties overlap, during the hazard

identification process.

3.6.2. Consultation should include discussions on the following:

3.6.2.1. the design, construction, installation, maintenance and testing of electrical

equipment

3.6.2.2. or electrical installations

3.6.2.3. design change or modification

3.6.2.4. inadequate or inactive electrical protection

3.6.2.5. where and how electrical equipment is used. Electrical equipment may be subject

to operating conditions that are likely to result in damage to the equipment or a

reduction in its expected life span. For example, equipment may be at greater risk

of damage if used outdoors or in a factory or workshop environment

3.6.2.6. electrical equipment being used in an area in which the atmosphere presents a

risk to health and safety from fire or explosion, for example confined spaces

3.6.2.7. type of electrical equipment. For example, ‘plug in’ electrical equipment that may

be moved around from site to site, including extension leads, are particularly liable

to damage

3.6.2.8. the age of electrical equipment and electrical installations

3.6.2.9. work carried out on or near electrical equipment or electrical installations, including

electric overhead lines or underground electric services, for example work carried

out in a confined space connected to plant or services.

3.6.2.10. Exposure to high electromagnetic fields (EMF) may also present a potential

hazard for workers with some medical conditions, for example pace makers. CIP

will gather this information as part of the project induction and if applicable will

inform the concerned worker/s about EMF hazards on site.

3.7. Safety in design

3.7.1. Designers must give CIP a written report/Design Risk Assessment that specifies the

hazards associated with the design of the structure that, so far as the designer is

reasonably aware:

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 8 OF 24

3.7.1.1. Create a risk to the health or safety of persons who are to carry out electrical work

on the structure or part, and

3.7.1.2. Are associated only with the particular design and not with other designs of the

same type of structure.

3.7.2. Designers should consider possible safe electrical work methods and health and safety

control measures when producing any final design documents and the safety

report/Design Risk Assessment for the structure.

3.7.3. Each state and territory Electricity Regulators and Electricity Supply Authorities require

specific class/level of competence for undertaking electrical design and installation works

which CIP will take into account while selecting the electrical consultants and contractors

for the project.

3.8. General Electrical Safety Requirements

3.8.1. Core Balance Earth Leakage Device/Safety Switch/Residual Current Devices (RCD)

3.8.1.1. RCDs must comply with AS 3190

3.8.1.2. Protect every single phase final sub-circuit and final sub-circuits supplying hand

held or portable equipment with a core balance earth leakage device/RCD with a

rated tripping current not exceeding 30mA.

3.8.1.3. Ensure RCD is fitted at the switchboard where the final sub-circuit originates and

protects individual circuits or a group of circuits.

3.8.1.4. Where electrical supply can only be obtained from a permanent wiring power

outlet then connect the RCD at the power outlet.

3.8.1.5. Prior to connecting any electrical equipment, the RCDs must be checked by push

button test to ensure correct functioning of the RCD.

3.8.1.6. All RCDs shall be millisecond tested and tagged by a licenced electrician monthly

and recorded on the site electrical register.

3.8.1.7. Note: While RCDs significantly reduce the risk of electric shock they do not

provide protection in all circumstances. For example, an RCD will not trigger off

electricity supply if a person contacts both active and neutral conductors while

handling faulty plugs or electrical equipment and electricity flows through the

person’s body, unless there is also a current flow to earth.

3.8.1.8. There are two types of RCDs viz.

▪ Type 1 – RCDs that have residual current rating not exceeding 10mA and a tripping time within 30ms. These are most sensitive and required for electrical equipment that is directly connected to people e.g. patients in hospital.

▪ Type 2 - RCDs that have residual current rating greater than 10mA but not exceeding 30mA and a tripping time within 300ms. These are most suitable for personal protection against injury including electric shock.

3.8.2. Switchboards

3.8.2.1. Ensure that construction supply switchboards are of robust weatherproof

construction

3.8.2.2. Must have a locking device.

3.8.2.3. the protective doors or lids are attached in a way that will not damage flexible

extension cords connected to the board.

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 9 OF 24

3.8.2.4. holes provided for cord access are bushed/protected to prevent damage to the

cords.

3.8.2.5. Secured to a permanent wall or a temporary structure

3.8.2.6. Ensure that all switchboards, other than the main switchboard, have an isolating

switch that removes power from all outgoing circuits when it is in the "open"

position. Do not use RCD as the isolating switch.

3.8.2.7. Ensure all switchboard enclosures are fitted with a clear Perspex sheet

located on the front of the panel upon opening of the switchboard doors.

NOTE: The Perspex panel shall be removable with four screws located in each

corner with cut-outs for access to circuit breakers switches. The purpose of this

panel is to ensure that on opening the switch board, all switch gear and live

components cannot be accessed unless the Perspex panel is removed. The

Perspex should not be removed at any time while testing. The only time the

Perspex may be removed is when the power has been turned off at the source.

3.8.3. Sub-mains

3.8.3.1. Protect all sub-mains with circuit breakers, or HRC (high rupturing capacity) fuses.

3.8.3.2. Circuit breakers on sub-mains must be able to be locked in the ’"open" position

and tagged. This is to ensure that it cannot be accidentally closed if isolated by an

inspector or a licensed electrician.

3.8.4. Sub-Circuits

3.8.4.1. Protect final sub-circuits with an overcurrent circuit breaker labelled by a licensed

electrician to identify the outlets or equipment they supply.

3.8.4.2. Isolate all power final sub-circuits, other than those supplying portable equipment,

at the completion of work each day except for sub-circuits for amenities and

equipment which operate outside normal working hours.

3.8.4.3. Distinguish final sub-circuit wiring from permanent wiring by using cable of a

different colour or by attaching iridescent/fluorescent yellow tape printed with the

words "Construction Wiring". Space the tape at intervals of not more than 5

metres.

3.8.5. Power Outlets / GPOs

3.8.5.1. Ensure that every 240 volt three pin plug general outlet/GPO is rated at 10

amperes (10A) minimum.

3.8.5.2. GPO is controlled by a double pole switch which operates in both the active and

neutral conductors.

3.8.5.3. Use GPOs within site sheds only to supply power to plant and lighting within or

immediately adjacent to the shed.

3.8.5.4. Protect GPO with RCD and do not use them to supply power to any other part of

the building, structure or construction work site.

3.8.5.5. Do not use double adaptors, 3 pin plug ("piggy back") adaptors and similar fittings.

3.8.5.6. If portable outlet devices are connected to permanent wiring with a flexible cord

and 3 pin plug, ensure that they comply with AS 3105 have 240V socket outlets

with overcurrent and RCD protection.

3.8.5.7. Ensure that power supplied from a permanent wiring outlet has RCD protection.

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 10 OF 24

3.8.6. Extension Leads/Cords & Fittings

3.8.6.1. Ensure that 240 volt flexible extension cords are heavy duty sheathed types which

comply with AS 3199.

3.8.6.2. Ensure that 3 pin plugs and cord extension sockets used on flexible extension

cords and portable power tools are either a non-rewirable (moulded) type or a

transparent type.

3.8.6.3. Fit three pin plugs to flexible extension cords in the way described in AS/NZS

3000.

3.8.6.4. Do not use cables normally used for fixed wiring as flexible extension cords.

3.8.6.5. Do not locate flexible extension cords with plug socket connections in wet places

or places where they are subject to damage by liquids.

3.8.6.6. Locate flexible extension cords above any work area or passageway so that clear

access is provided, beneath them.

3.8.6.7. Use lead stands and or plastic hooks to suspend the extension leads above the

ground/floor to minimise trip hazard and protect leads from damage.

3.8.6.8. Ensure that fittings for flexible conductors and flexible extension cords are wired

identically and that the identity of actives, neutral and earth connections are

preserved in a like manner.

3.8.6.9. Confine flexible extension cords used in multi-storey construction to the same floor

as the power source. Obtain power for use in stairwells from the floor above or the

floor below the work area except for falsework or lift or service shafts.

3.8.7. Transportable Construction Buildings/Site Office & Amenities

3.8.7.1. Ensure that electrical installations to transportable construction buildings comply

with the following requirements:

▪ If supply is by means of a flexible cord, do not take it from one transportable building to another transportable building.

▪ Do not use flexible cords longer than 15 metres to supply a transportable building.

▪ Connect each amenities building supplied by flexible cord to a final sub-circuit protected by RCD with a rated tripping current not exceeding 30mA.

▪ Protect flexible cords from mechanical damage.

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 11 OF 24

3.8.8. Portable Generators

3.8.8.1. Ensure that all portable generators comply with AS 2790 - Electricity Generating

Sets - Transportable (up to 25 KW).

3.8.8.2. Ensure that the power supply for all construction wiring emanating from a portable

generating set complies with the Code of Practice including protection by RCD

with a rated tripping current not exceeding 30mA.

3.8.9. Safety Barriers and Signs

3.8.9.1. As required, barriers and signs may be designed, erected or installed to:

▪ protect electrical workers from inadvertently contacting energised exposed parts

▪ ensure that access to and egress from the work location of live work allows for clear, unobstructed passage

▪ warn others and direct people away from dangerous work areas.

3.8.9.2. Different kinds of safety barriers may be required for different purposes. For

example:

▪ to protect electrical workers from inadvertently contacting energised exposed parts—a physical safety barrier should consist of a non-conductive material such as wood or plastic or, alternatively, correctly earthed steel and be strong enough to withstand the impact from falling objects or loose material

▪ to exclude persons generally from a work area where there is a risk of energised exposed parts—secure housings, enclosures, doors and room may provide appropriate safety barriers.

3.8.9.3. The barrier must be erected safely. This may require switching off or isolating the

electricity supply while the barrier is installed.

3.8.9.4. A barrier may be temporary or permanent and, if applicable, should clearly

designate the safe work area by defining the approach path to the relevant piece

of equipment.

3.9. Energisation, De-energisation & Start-up Procedure

3.9.1. Electrical

3.9.1.1. Prior to Energisation

▪ Where construction work is incomplete and may impact on the integrity of the installation, an assessment will be carried out to assess the mechanical protection that may be required for additional protection of electrical equipment, including cabling that may be damaged due to the ongoing construction activities.

▪ All cable trays that are to be carrying LIVE circuits to be clearly signed “DANGER LIVE CABLES ON TRAY”. All equipment energized to be signed “LIVE EQUIPMENT UNDER COMMISSIONING”. All switchboard doors locked and clearly signed “SWITCHBOARD ALIVE CAUTION 415 VOLT” and “DANGER AUTHORIZED PERSONNEL”.

▪ All required notification to be submitted to the Principle Contractor Representative & Nominated Electrical Subcontractor 48 Hours prior to energisation requirements. Copies of all required notices to go to CIP to be distributed as required.

▪ Each contractor associated with energizing Electrical Services and following these procedures, must have at least one current Level 2 First Aider as part of the energizing crew, with a CPR refresher within the 12 month period as per the requirement of the First Aid Certificate as well as

▪ Induction will take place on site with the induction being conducted by the Principle Contractor Representative. All involved will sign off on the sheet provided at the completion of the induction. Copy of the signed Energisation Induction Register (SSMP-072) shall be made available at the Site Office.

▪ This induction procedure is to be reviewed in the first week of use and then monthly or as required until all Energisation on the project is complete.

3.9.1.3. NO WORK on Live Electrical Equipment

▪ No work is to be carried on any sub-board, switchboard or control board whilst any circuits, apparatus or part of the installation is energised

▪ Work is only to be carried out when the sub-board, switchboard or control board is de-energized at the source of the power.

▪ Locked out with padlocked and tested to confirm the power is isolated at Power source.

3.9.1.4. Testing & Commissioning of Electrical Boards

▪ Notify CIP, prior to any live testing.

▪ Live testing is only to be carried out when there is no other alternative method.

▪ After due consideration is given to the task and it is determined that testing on live equipment is required (post risk assessment), the development of a SWMS approved by the CIP Site Manager and the use of a “Live rescue Kit” and relevant PPE must be implemented.

▪ The following minimum requirements must be met:

- Post the following signs,

- Electrical commissioning in progress authorized personnel only.

- A minimum of 2 meter area to be barricaded off.

- The area to clear of rubbish and materials.

- Clearly identify emergency shut down switch location, route and how it is identified.

3.10. Inspection and testing of electrical equipment

3.10.1. Generally inspection and testing of electrical equipment may involve, in part:

3.10.1.1. looking for obvious damage, defects or modifications to the electrical equipment,

including accessories, connectors, plugs or cord extension sockets

3.10.1.2. looking for discolouration that may indicate exposure to excessive heat,

chemicals or moisture

3.10.1.3. checking the integrity of protective earth and insulation resistance

3.10.1.4. checking that flexible cords are effectively anchored to equipment, plugs,

connectors and cord extension sockets

3.10.1.5. looking for damage to flexible cords

3.10.1.6. checking that operating controls are in good working order i.e. they are secure,

aligned and appropriately identified

3.10.1.7. checking that covers, guards, etc. are secured and working in the manner

intended by the manufacturer or supplier

3.10.1.8. checking that ventilation inlets and exhausts are unobstructed

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 18 OF 24

3.10.1.9. checking that the current rating of the plug matches the current rating of the

associated electrical equipment.

3.10.1.10. A record of inspection and testing will be kept until the electrical equipment is

next tested, permanently removed from the workplace or disposed of. The

record of inspection and testing must specify name of person who carried out the

testing, date of testing, outcome of testing and date of next testing. The record of

inspection and testing could be in the form of tag, log book, register, database or

similar. Each subcontractor or PCBU is responsible to maintain record of

inspection and testing for the electrical equipment owned, hired and or used by

them. CIP will ensure that regular workplace inspections check these records.

3.10.1.11. The electrical installations on CIP project sites where construction and or

demolition activities are being undertaken will comply with the requirements of

AS/NZS 3012.

3.10.1.12. Fault finding should first be attempted in a de-energised environment using de-

energised testing methods. If unsuccessful, energised testing methods may be

used subject to meeting the requirements of the WHS Regulations, Code of

Practice and this procedure, for working energised.

3.10.1.13. Where required, CIP will ensure that any measuring and monitoring equipment

used for electrical works are calibrated and or verified prior to its use.

Subcontractors using their electrical equipment should provide copy of the

calibration or verification records for such equipment to CIP. Testing equipment

used for detecting an energised source should be trialled first to prove that it is

functioning correctly immediately before and after the test has taken place.

Proximity voltage testers are not reliable in proving de-energised and should only

be treated as an indicator. Proximity voltage testers should be tested for correct

operations immediately before use and again immediately after use, particularly if

the test result indicates zero voltage, to confirm that the instrument is still working

correctly.

3.10.1.14. All tools, instruments and equipment used for electrical work must be maintained,

appropriate and fit for purpose. Insulated tools and equipment must be suitable

for the work and be maintained in good working order, including by regular

maintenance, inspection and testing. Where any doubt exists that the insulation

of tools and equipment might not be adequate they should not be used.

Maintenance and inspection should be carried out according to manufacturer’s

instructions.

3.10.1.15. Metallic tapes, ladders, mobile scaffolds, etc. are not permitted for electrical work

and are not to be used in close proximity of electrical equipment where an

electrical hazard may result from their use.

3.10.1.16. Insulating barriers and insulating mats used for electrical safety purposes must

comply with AS/NZS 2978. Insulated barriers should be of suitable material to

effectively separate electrical workers from adjacent energised equipment.

Insulated covers and mats should be visually inspected for possible defects

before and after each use.

3.10.1.17. All RCDs shall be millisecond tested and tagged by a licenced electrician

monthly and recorded on the site electrical register.

3.10.2. New Equipment

Brand-new electrical equipment that has never been put into use (i.e. other than second hand equipment) does not have to be tested before first use however an inspection tag must be fitted to indicate the date the electrical equipment was placed into service so that the next scheduled inspection can be carried out accordingly.

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 19 OF 24

3.10.3. Hire equipment

CIP will ensure that subcontractors or PCBUs using hired equipment on site have their equipment inspected at the commencement of each hire and tested every three months. The subcontractor or PCBU using the electrical equipment hired out must ensure that, for the period of the hire, the equipment meets all applicable inspection and testing requirements under the WHS Regulations and Code of Practice. All RCDs shall be millisecond tested and tagged by a licenced electrician monthly and recorded on the site electrical register.

3.10.4. Personal Protective Equipment (PPE)

3.10.4.1. PPE for electrical work, including testing and fault finding, must be suitable for

the work, properly tested and maintained in good working order. The PPE must

be able to withstand energy at the point of work when working energised.

3.10.4.2. Training must be provided in how to select and fit the correct type of equipment,

as well as training on the use and care of the equipment so that it works

effectively.

3.10.4.3. Depending on the type of work and the risks involved, the following PPE should

be considered:

▪ Face Protection - use of a suitably arc rated full face shield may be appropriate when working where there is potential for high current and arcing.

▪ Eye Protection - metal spectacle frames should not be worn. ▪ Gloves - use gloves insulated to the highest potential voltage expected for

the work being undertaken. Leather work gloves may be considered for de-energised electrical work.

▪ Clothing - use non-synthetic clothing of non-fusible material and flame resistant. Clothing made from conductive material or containing metal threads should not be worn.

▪ Footwear - use non-conductive footwear, for example steel toe capped boots or shoes manufactured to a suitable standard.

▪ Safety Belt/Harness - safety belts and harnesses should be checked and inspected each time before use with particular attention being paid to buckles, rings, hooks, clips and webbing.

3.11. Electrical Safety for Use of Cranes and Mobile Plant

3.11.1. Use of cranes and mobile plant include mobile cranes, vehicle-loading cranes, concrete

placing booms, elevating work platforms, load shifting equipment like forklifts,

excavation and earthmoving equipment and high load transportation vehicles poses

electrical risks whilst working in the vicinity of overhead and underground electrical

services.

3.11.2. Contact with energised overhead electric lines by operating cranes or mobile plant can

cause death, electric shock or other injury to plant operators and workers.

3.11.3. It can be difficult for crane or plant operators to see overhead electric lines or judge

their height and approach distances and work zones are required for the safe operation

of cranes and mobile plant and the safety of crane or plant operators and other

workers.

3.11.4. The approach distance for each work zone will vary depending on the voltage of the

overhead electric line and the level of authorisation of each person doing the work. As

the risk increases a greater approach distance is required.

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 20 OF 24

3.12. Electrical Safety for Underground Electric Cables

3.12.1. Working in the vicinity of underground electric lines or cables may involve potential

contact with exposed energised parts. For example:

3.12.1.1. a plumber cutting a conductive water pipe that is part of the site’s electrical

installation’s

3.12.1.2. earthing system

3.12.1.3. a fencing contractor digging holes or driving posts where an electrical cable could

be buried

3.12.1.4. digging holes with metal hand tools e.g. spades, shovels, picks, forks and

hammers

3.12.1.5. driving implements into the ground e.g. star pickets where underground services

may be located

3.12.1.6. a plumber digging a trench to locate underground pipes

3.12.1.7. excavating trenches with earth moving machinery using a metal toothed bucket,

and

3.12.1.8. using mobile cranes or heavy vehicles that become bogged.

3.12.2. An injury resulting from damage to energised underground electricity cables is usually

caused by electric shock or the explosive effects of arcing current and by the fire or

flames which follow when the sheath of a cable is crushed or contact is made between

the individual phases of a cable. The presence of gas or a mixture of gases in a trench

could be ignited by an electrical charge or an electrical arc resulting in a fire or

explosion, the severity of which depends on the gaseous mixture.

3.12.3. Gas can be present in the ground due to gas pipe damage or leakage, sewerage pits,

chemical reactions or leaching and the accumulation of airborne gases in low lying

areas. Gas can be introduced by the type of work being done including oxy-acetylene

cutting or chemical grouting.

3.12.4. Before starting work, CIP will ensure that underground electrical cables which could

create a risk if contacted or damaged are identified and Permit to Excavate may be

necessary as per CIP Excavation Procedure.

3.12.5. CIP will manage the risks associated with underground electrical services at the

workplace during construction activities, including:

3.12.5.1. Implementing specific control measures before using excavators or other

earthmoving machinery for excavation as per Excavation Procedure.

3.12.5.2. Obtaining underground service plans and information on current underground

electrical services about the areas at the workplace where the construction work is

to be carried out and providing these to the relevant contractors. Information on

the location of underground services may be obtained by contacting the "Dial

Before You Dig" service

3.12.5.3. Providing other relevant parties including any subcontractors and plant operators

carrying out the construction work with information about electrical services and

other plans so the information is considered when planning all work in the area.

3.13. Emergency Management

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 21 OF 24

3.13.1. Emergency related to mobile plant & equipment

3.13.1.1. Planning work in the vicinity of overhead or underground electric lines should

include possible emergency situations and the rescue and evacuation of workers.

3.13.1.2. Emergency risk assessment will cover potential emergency situations resulting

from mobile plant or attached equipment contacting energised electric lines

including:

▪ contact with energised electric lines when the electricity trips

▪ contact with the energised electric lines when the electricity does not trip

▪ a fire starting on the mobile plant or attached equipment

▪ a grass or bushfire starting,

▪ a tyre catching fire or tyre disintegration leading to a tyre explosion, or

▪ a combination of any of the above

3.13.1.3. An emergency plan will be developed from the results of the risk assessment,

consulting with workers, the Electricity Supply Authority or the person with

management or control of the electric line or premises and emergency service

providers.

3.13.1.4. Where contact is made with an energised overhead electric line or a flash-over

occurs between an energised overhead electric line and a crane or mobile plant

following actions may be taken:

▪ Try to break the crane or mobile plant’s contact with the energised overhead electric line by moving the jib or driving the mobile plant clear only if safe to do so.

▪ If it is not possible to break the contact with the energised overhead electric line, the operator of the crane or mobile plant should remain inside the cabin of the crane or on the plant item. Contact the Electricity Supply Authority immediately to isolate electricity to the energised overhead electric line. The operator should remain in place until the electricity has been isolated and the ‘all clear’ given by the Electricity Supply Authority.

▪ If it is essential to leave the cabin or the operator’s position because of fire or other life threatening reason, then jump clear of the equipment. Do not touch the equipment and the ground at the same time. When moving away from the equipment, the operator should hop or shuffle away from the mobile plant with both feet together until at least 8 metres from the nearest part of the crane or operating plant. Under no circumstances run or walk from the crane or mobile plant as voltage gradients passing through the ground may cause electricity to pass through the body resulting in an electric shock.

▪ Warn all other people and members of the public to keep 8 metres clear from the crane or mobile plant. Do not touch or allow other people to touch any part of the crane or mobile plant. Do not allow people to approach or re-enter the vehicle until the Electricity Supply Authority has determined the site safe. Remember electricity flows through the ground, so an electric shock could be received from walking close to the scene. If the crane or mobile plant operator is immobilised, ensure the electricity supply has been isolated and the site made safe before giving help.

▪ Unauthorised, unequipped people should not attempt to rescue a person receiving an electric shock. Secondary deaths often occur because others get electrocuted trying to help earlier victims. If the crane or mobile plant operator is immobilised, ensure the electricity supply has been isolated and the workplace has been made safe before giving help.

3.13.1.5. Warning: When a crane or item of plant inadvertently contacts overhead electric

lines, circuit protective devices may operate to automatically turn the electricity off.

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 22 OF 24

However some protection devices are designed to automatically re-close, there by

re-energising the electric lines after a short period of time, typically 1-4 seconds.

3.13.2. Inspecting plant after contact with electric lines

3.13.2.1. When a crane or mobile plant has been in contact with an energised overhead

electric line, it should be checked by a competent person for damage to the

components of the crane or mobile plant. All recommended actions are to be

completed before the crane or mobile plant is returned to service.

3.13.2.2. Tyres on cranes and mobile plant that have been in contact with overhead electric

lines where electrical flash-over and current flow occurs through the rubber tyres

should be considered as a potential hazard. These rubber tyres may catch fire or

have the potential to explode. A lesser known danger is when combustion takes

place within the tyre and there are no apparent external signs. When excessive

heat is developed in or applied to a tyre as in the case from contact with overhead

electric lines, it can initiate a process known as pyrolysis, which is the

decomposition of a substance by heat. This can generate a build-up of flammable

gases and pressure within the tyre, which may rupture or explode.

3.13.2.3. Vast amounts of energy can be released by a tyre explosion often leading to

significant equipment damage, serious injuries or fatalities. Pyrolysis related

explosions are very unpredictable and have been known to occur immediately or

up to 24 hours after initiation. An explosion can occur where no fire is visible. The

danger area can be up to 300 metres from the tyre.

3.13.2.4. A crane or mobile plant with rubber tyres involved in an incident where contact is

made with overhead electric lines which results in discharges or flash-over of

electrical current through the tyres should be considered as a potential hazard. If

anyone suspects there is a danger of a tyre explosion, as in the case of a mobile

crane contacting overhead electric lines, the procedure should include:

▪ parking the crane in an isolation zone, with a minimum 300 metre radius ▪ removing everyone from the area and not allowing entry to the isolation

zone for 24 hours, and ▪ alerting firefighting services.

3.13.3. First aid – electric shock

3.13.3.1. do not touch the victim if they are in contact with live conductors.

3.13.3.2. if possible, disconnect the power source or use a LV Rescue Kit to remove victim

from electric source if disconnection not possible.

3.13.3.3. relocate victim to safe environment and call for medical assistance.

3.13.3.4. commence and maintain resuscitation until arrival of emergency services.

Section 5 of Site Safety Management Plan describes the procedure for dealing with various

emergency scenarios including electrical related emergencies. Special consideration must

also be given in relation to other higher-risk workplaces including confined spaces, working at

heights (e.g. elevating work platforms), workplaces with hazardous atmospheres which

present a risk to health or safety from fire or explosion, and trenches, shafts and tunnels.

3.14. Incident Management

3.14.1. Any incident related to electrical safety must be reported in accordance with Section 15

of the Site Safety Management Plan – Incident/Accident Management & Reporting.

3.14.2. There are four main types of electrical injuries:

CIP DEVELOPING RELATIONSHIPS BUILDING SUCCESS> C-S-MG-007>1.0>03/17 PAGE 23 OF 24

3.14.2.1. electrocution due to electric shock

3.14.2.2. electrical shock

3.14.2.3. burns

3.14.2.4. indirect injuries such as broken bones from falling, heart attack, cuts, scrapes, etc.

3.14.3. The severity of electric shock depends on the path of current through the body, amount

of current flowing through the body (Amps) and duration of the shocking current

through the body. Note: Low voltage does not mean low hazard.

3.14.4. Currents above 10mA can paralyse or freeze muscles and currents more than 75mA

can cause a rapid, ineffective heartbeat and death will occur in few minutes if effective

resuscitation or defibrillator is not used.

3.14.5. Quick action after an electrical incident that causes injury can save a life or significantly

reduce the severity of the injury. Even if an electrical incident does not appear to have

caused injury at the time, there may be some delayed effects.

3.14.6. Any person who is involved in an electrical incident involving an electric shock should

receive medical attention.

3.14.7. Incidents that expose a worker or any other person to a serious risk from an electric

shock must be notified to the regulator and may also be notifiable separately to an

electrical safety regulator.

3.15. Review

3.15.1. Site Manager should review and revise any existing risk control measures related to

electrical work during tool box or site meetings, using the same methods as the initial

hazard identification process:

3.15.1.1. When the control measure does not minimise the risk so far as is reasonably

practicable.

3.15.1.2. Before a change at the workplace that is likely to give rise to a new or different

health and safety risk that the control measure may not effectively control.

3.15.1.3. If a new hazard or risk is identified.

3.15.1.4. If the results of consultation indicate that a review is necessary.

3.15.1.5. If a HSR requests a review.

3.15.2. When reviewing control measures, Preliminary Risk Assessment, SWMS and any

authority permit must be reviewed and revised where necessary.

3.16. Monitoring

The risk controls must be regularly monitored to ensure the workplace remains safe for workers. This

monitoring is to be carried out weekly Site Manager’s Inspection (SSMP 038), SWMS Compliance

Verification (SSMP 039) and Project OHS Audit (SSMP 044). If in doubt or electrical equipment

considered to be unsafe, then stop work and seek advice from licensed electrician/CIP Site Manager

before recommencing the work.
