SECTION 2: HAZARD IDENTIFICATION, RISK ANALYSIS AND RISK CONTROL (HIRARC)
The HIRARC Team has to determine the most appropriate way(s) of identifying hazards. These may include brainstorming, systemat ic process reviews, Job Hazard Analysis (JHA), Job Observations and Job Safety Analysis (JSA). When identifying hazards, the HIRARC Team has to consider if the hazards could cause harm beyond the immediate area of their work.
2.1 Hazard Identification
a) Select a “Work Activi ty” from the project works master schedule or “Work Breakdown Structure” (WBS) or project work method statement master list for analysis and all information required has to be documented in HIRARC Form.
b) Break down work activity into its sub-activities to facilitate the identification of all foreseeable hazards associated with the work. These sub-activities constitute the different steps that make up the work activity.
c) For each sub-activity, identify the potential hazard(s) and record them in the “Hazard” column. List each hazard in a separate row in the table.
d) The following categories of hazards should be considered:■ physical (e.g., fire, noise, ergonomics, heat, radiation);■ mechanical (e.g.,moving and dangerous parts, rotating parts);■ electrical (e.g., voltage, current, static charge,magnetic fields);■ chemical (e.g., flammables, toxics, corrosives, reactivematerials);■ biological(e.g.,airorblood-bornepathogens,vector-bornedisease,virus,bacteria);and■ psychosocial (e.g., stress, fatigue).
4
e) Workplace or Work-related Factors to consider when identifying hazards:■ proximity of hazardous activities to one another;■ compatibility of work activities;■ non-routinework activities and situations; and Environmental conditions
2.2 Risk Analysis
2.2.1 Risk Matrix
This CIS recognises the various risk evaluation methods and matrices practised and preferred by contractor. While this CIS does not restrict workplaces to its choice of matrices, the numeric 5x5 Risk Matrix is recommended. An example is given in Tables 1.
2.2.2 The Matrix recommended by this CIS is as follows:
Table 1: 5x5 Risk Matrix with numeric (quantity) and word (quality) ratings
Likelihood
SeverityRare (1)
Remote (2)
Occasional (3)
Frequent (4)
Almost Certain (5)
Catastrophic (5) 5 (Med) 10 (Med) 15 (High) 20 (High) 25 (High)
Major (4) 4 (Med) 8 (Med) 12 (Med) 16 (High) 20 (High)
Moderate (3) 3 (Low) 6 (Med) 9 (Med) 12 (Med) 15 (High)
Minor (2) 2 (Low) 4 (Med) 6 (Med) 8 (Med) 10 (Med)
Negligible (1) 1 (Low) 2 (Low) 3 (Low) 4 (Med) 5 (Med)
2.2.3 Existing Controls
Existing controls are control measures that are already in place, or required to be implemented to carry out the work activity. Assessment of severity and likelihood should be made on the assumption that existing (or required) controls are in place. Existing (or required) controls that do not influence severity should not be taken into account when assessing severity. Existing (or required) controls that do not influence likelihood should not be taken into account when assessing likelihood. For the purpose of CARA-HIRARC, existing control measures were assumed not available.
2.2.4 Assessment of Severity
Taking the existing risk controls into consideration, the HIRARC Team has to rate the severity of the possible injury or ill-health. When using the 5x5 matrix, the guidance given in Table 2 should be used when selecting the level of severity. When using other matrices, equivalent guidance for severity should be used and described in adequate details for adoption by users of those matrices.
5
Table 2: A guide to severity rating
Level

Severity
Catastrophic
Description
Death, fatal diseases or multiple major injuries.
4 Major Serious injuries or life-threatening occupational diseases (includes amputations, major fractures, multiple injuries, occupational cancers, acute poisoning, disabilities and deafness).
3 Moderate Injury or ill-health requiring medical treatment (includes lacerations, burns, sprains, minor fractures, dermatitis and work-related upper limb disorders).
2 Minor Injury or ill-health requiring first-aid only (includes minor cuts and bruises, irritation, ill-health with temporary discomfort).
1 Negligible Negligible injury.
Should HIRARC Team have difficulty developing a consensus to the severity level, the Team is to gather more information and/or consult an industry expert.
2.2.5 Assessment of Likelihood
Taking the existing risk controls into consideration, the HIRARC Team has to rate the likelihood the hazard may cause injury or ill-health. When assessing likelihood, the HIRARC Team has to consider personal risk factors - existing medical condition(s) of the person(s) involved in the activity that may affect the likelihood level. When using the 5x5 matrix, the guidance given in Table 3 should be used when selecting the level of likelihood.
Table 3: A guide to likelihood rating
Level Likelihood Description
1 Rare Not expected to occur but still possible.
2 Remote Not likely to occur under normal circumstances.
3 Occasional Possible or known to occur.
4 Frequent Common occurrence.
5 Almost Certain Continual or repeating experience.
When using other matrices, equivalent guidance for likelihood should be used and described in adequate details for adoption by users of those matrices. Should HIRARC Team members have difficulty developing a consensus to the likelihood level, the Team is to gather more information and/or get advice from an industry expert.
6
2.2.6 Risk Prioritisation Number (RPN)
The RPN is obtained by multiplying the values of Severity and Likelihood level (Values in the “S” and “L” columns of the HIRARC table), that is, RPN = S x L.
2.2.7 Classification of Risk—Risk Matrix
Compare the RPN against the Risk Matrix in Table 4. Risk controls must be implemented so that the risk levels are not in the red zone (“High Risk”) before work commences. Additional Risk Controls should be implemented till:
■ Riskcontrols for thehazard in theyellowzone (“MediumRisk”)arealreadyAsLow As Reasonably Practicable (ALARP); or
■ The risk level is in the green zone (“LowRisk”).

Moderate (3) 3 6 9 12 15
Minor (2) 2 4 6 8 10
Negligible (1) 1 2 3 4 5
Which are the areas within the Matrix to be classified as Low (green), Medium Yellow) and High risks (Red). The categorisation of risk may be done based on, but is not limited to, industry practice, policies of the workplace and risk appetite of the organisation.
7
2.2.8 Action for Risk Levels
The following actions are to be implemented based on the current risk level.
Table 5: Low, Medium and High Action for Risk Level
Risk level Risk Acceptability Recommended Actions
Low Acceptable • No additional risk controlmeasuresmay be needed.• Frequentreviewandmonitoringofhazardsarerequired
to ensure that the risk level assigned is accurate and does not increase over time.
Risk level Risk Acceptability Recommended Actions
Medium Tolerable • A careful evaluation of the hazards should be carriedout to ensure that the risk level is reduced to as low as reasonably practicable (ALARP) within a defined time period.
• Interim risk control measures, such as administrativecontrols or PPE, may be implemented while longer term measures are being established.
• Management attention is required.
High Not acceptable • High Risk level must be reduced to at least Medium Risk before work starts.
• There should not be any interim risk control measures. Risk control measures should not be overly dependent on PPE.
• If practicable, the hazard should be eliminated before work starts.
• Management review is required before work starts.
2.2.9 Risk Evaluation for Health Hazards
Exposure assessments should be conducted to estimate employees’ exposure to health hazards where appropriate. Exposures can be estimated by qualitative assessment or quantified by direct measurement. All exposure measurements should be conducted by competent persons using recognised methods, acceptable standard procedures and standard calibrated equipment. Exposure estimates are then compared to established Permissible Exposure Level (PEL) or other health standards to establish the likelihood of the ill-health effects. Based on exposure assessment and risk evaluation, health exposure risks can be ranked to enable prioritisation of action plans to lower these risks. When assessing the risk of health hazards (e.g., noise, chemicals, biological agents and ergonomics), relevant risk factors should be taken into consideration. It is also important to consider other factors which may influence likelihood such as: potential cumulative exposures; potential synergistic effects between certain health hazards (e.g. exposure to excessive noise and trichloroethylene [TCE] will increase likelihood of hearing impairment); or any limitation in health standards if they do not consider all exposure routes. (e.g., potential dermal or ingestion risks are generally not taken into account when setting PELs).
2.3 Risk Control
Selection of risk control measures should be based on the Hierarchy of Control. Elimination of hazard should take precedence, where practicable. Where elimination is not feasible, measures should be
8
taken to reduce the risk by following the Hierarchy in the recommended order: substitution, isolation, engineering controls, administrative controls and personal protective equipment. For the purpose of this CIS: 25 2018 CARA-HIRARC, the last three hierarchy of control such as Engineering Control (EC), Administrative Control (AC) and Personal Protective Equipment Control (PC) are adopted as the Recommended Control Measures (RCM).
RCM in HIRARC Table of this CIS are the generic good practices and should not be taken as sole mandatory control measures. Contractor should determine their own customized RCM in accordance with the nature of their work activities. There is three most common Personal Protective Equipment’s Control (PC) recommended by this CIS i.e. Safety Helmet, Safety Shoes/boots and safety vest for all work activities spelled.
2.3.1 Additional Controls
Check the risk level (or RPN) for acceptability. If the risk level “High” or RPN is in the “High” zone, the risk must be eliminated or reduces to at least a “Medium” level by additional controls. When considering additional controls to reduce risk, control measures that are higher up in the Hierarchy of Control should be considered first.
2.3.2 Hierarchy of Control (HOC)
The control of hazards and reduction of risk can be accomplished by following the hierarchy of Control (see figure 2).
Figure 2: HOC form
PPE(Provide safety
helmet, safety shoes, earmuff etc)
ELIMINATION(Remove the sources of hazard completely)
SUBSTITUTION(Replace hazardous work activity
with less hazardous)ISOLATION
(Separate the hazard from people or people from hazard)
ENGINEERING(Physical changes, e.g redesign
by adding safeguards)
ADMINISTRATIVE(Provide training procedure, signage, work
rotation, safe work procedures etc)
More Effective
Less Effective
A control measure that is higher on the Hierarchy is often more effective as the risk is reduced at or close to the source. The Control measures in the Hierarchy are not to be taken as isolated or single solutions. Generally, it is more effective to use a combination of control measures. For example, engineering controls work better with administrative controls like training and Safe Work Procedures.
9
SECTION 3: HIRARC Approval
Completed HIRARC table must be approved by the Project/Construction Manager of the contractor of the respective project. As far as is practicable, the contractor has to implement the recommended risk control measures as soon as possible. Contractor must ensure that an action plan is prepared to implement the measures. The plan to include a timeline for implementation and the names of the persons responsible for implementing the safety and health control measure. The contractor must ensure that the plan is monitored regularly until all the measures are implemented. The contractor must ensure that regular inspections and process audits are carried out to make sure that risk control measure have been implemented and are functioning effectively. After the implementation of additional controls, the “Existing Controls” and “Recommended Controls Measures” columns of the HIRARC table have to be updated.
SECTION 4: RECORDS OF HIRARC
The contractor shall ensure that the HIRARC records are kept safe and available at the duration of their project. The contractor needs to ensure that Risk Register is readily available for review by interested party or regulatory agencies.
SECTION 5: RE-EVALUATION WITH ADDITIONAL CONTROLS
When additional control(s) have been decided, re-rate the Severity, Likelihood and Risk Levels (or RPN values) and record them in the “S”, “L” and “RPN” columns in “Risk Control” section of the HIRARC table. The re-evaluated RPN should not be HIGHER than the initial RPN. The revised Risk levels (or RPN values) should preferably be kept within the low Risk (Green) zone, where feasible.
SECTION 6: CONSTRUCTION ACTIVITIES
There are 9 construction activities have been identified for the development of HIRARC under this standard. These 9 construction activities are identified as common activities for the purpose of developing HIRARC for construction project.
The user of this document may include other construction activities which may have potential hazards and suit the construction activities.
