The document discusses recommendations for improving the task risk assessment (TRA) process within ADGAS. It recommends that all job planners attend TRA meetings, that TRA members receive training, and that accident registers be used to determine risk likelihood. Site visits by TRA members prior to assessments are also recommended to properly identify hazards. The document then outlines the 8 step TRA process, including developing work method statements, identifying hazards and their effects, determining risk levels, and implementing and monitoring controls.

2. INTRODUCTION AND BACKGROUND
• DV (P) / I&Q Manager Advices to review the task risk
assessment process within ADGAS.
• A preliminary survey on TRA process has been carried out by
assigned task force from HSED, operation and maintenance.
• The objective of survey was to check on how this process is
tackled within other ADNOC groups and define any areas of
improvements and deliver the recommendations and
accordingly changes required.

3. RECOMMENDATIONS
• All job planners must be attend the TRA meeting.
• All TRA members including job planners must attend TRA & hazards
awareness course delivered by Adgas HSED.
• Accidents / incident register for last 5 years to be used during TRA, this
will help on probability rate (likelihood) decision.
• Hazards check list documents to be utilized during conducting TRA as a
guideline to identify the potential hazards for each activity.
Ref. Adgas HSE manual chapter 02 page 66 table 2-5.
• General safety notes in TRA form to be amended.
• TRA members must visit the site prior to conduct the TRA.
• The job officers will ensure that, the TRA mitigation control is briefed
to all workers on site prior to start the activities (task briefing talk).

5.  MS is developed by job planner.
 MS will explain on how the main task will be carried out.
 MS will break down the main task to sub tasks (activities).
 Each sub task has potential hazards.
 MS will be reviewed and approved by TRA team.
 MS will be briefed by job officers during site visit.

6.  TRA team must visit the site prior conducting TRA.
 Who should attend the TRA meeting ?
HSED –operation –engineering – job officer- job planner - Das fire rescue TL as per required.
 Job officers at site will brief TRA team on how the task will be carried out using MS
document.
 Site visit will help team to gather information and get full and clear pictures of how
the work will be carried out.
 Site visit will help team to indicate the associated hazards with each sub task.
 ADGAS hazards check list can be utilized as a guideline during site visit

7.  On completion of site visit, the team now can conduct the TRA in the office.
 Documents should be available during conducting TRA are:
TRA form – Hazards check list - Accidents/incidents register.
Risk matrix – MS.
 List each sub task (activity) in task column in (TRA form).
 List associated potential hazards against each sub task.
 List the relevant effect / harm for each hazards.
 Information about hazards and effects can be obtained from:
Adgas HSE manual, MSDS, Hazards substances manual, O&M standing instructions,
observation during site visit.

8.  In general, severity rate can be identified by experience, judgment and guidance.
 Guidance for severity rate is given in risk matrix on the scale from 1 to 5
(negligible to catastrophic)
 Severity rate will be identified for each effect on:
People, assets, environment & reputation.
 Examples of factors affecting severity rate:
Numbers of people in the activity, voltage, speed, weights, height ……...
 Examples of severity rate:
(5) Multiple fatalities: work on scaffolding, confined space.
(4) Single fatality: work at height above 2 meter, use 240 voltage.
(3) Major injury: work at height till 2 meter, use grinder, welding.
(2) Minor injury: manual handling, trips, harmful substances.
(1) Slight injury: this is including first aid case.

9.  In general, probability rate can be identified by accidents / incidents history register
and guidance.
 Guidance for probability rate is given in risk matrix on the scale from A to E.
 Examples of factors affecting probability rate: duration of exposures, quantity of
hazards materials involved, number of people involved in the activity, condition of equipment.
 Accidents/incidents register will help TRA team to take right decisions of likelihood.
 The risk register will provide information on the number of accidents/incidents
occurred in ADGAS per year (Average).

10.  Based on the severity and probability rate, now we can identify the risk level from
risk matrix.
 Product of severity and probability = risk level.
 Risk will be falling into one of three regions. L, M & H.
 High Risk: work should not be undertaken unless steps can be taken to minimize risk
and move it into the medium or low risk category.
 Medium Risk: as low as reasonably practicable (ALARP).
 Low Risk: this is considered an acceptable level of risk.
8/13/2011 10Prepared by Najeh Issa Sr. SSS ( P& SD).

11.  For each single potential hazard should be adequate mitigation control.
 Mitigation control should be adequate to minimize the risk level from high to
medium or from medium to low.
 If existing mitigation control cannot mitigate the high risk to medium risk ALARP, the
team will then develop ideas or additional mitigation control that will reduce the risk
to as low as reasonably practicable (ALARP). If they cannot, then the final
assessment will be NOT ACCEPTABLE.
 Final risk will be either low or medium.
 Final assessment (residual risk) will be either acceptable or not acceptable depend
on residual risk level identified.

12.  TRA document should given a reference number from HSED.
 At worksite, TRA document will be utilized as task briefing talk.
 If condition at worksite changed or/and introduce new hazards, then work will be
stopped / suspended.
 In above condition, Site safety specialist (SSS) to be informed, job officer and SSS
will decide the need for further TRA, if TRA is required, job officer will call for TRA
meeting (TRA Revisit).
 Implementation of Mitigation control should be monitored and followed up at
regular time to ensure effective implementation.

13.  All generic cautions that are covered during safety induction should not be included in the TRA.
 All safety checks and general site safety preparation that are covered by the work permit should
not be included in the TRA.
 TRA related documents are: TRA procedures, MS, TRA form, Risk register list. List of tasks that are
to be assessed, risk Matrix, accidents register list.
 Some example of what should be included in the General precautions in TRA format first page:
• Adhere strictly to ADGAS PTW System and HSE Manual.
• All concerned TRA and Method Statement must be attached with all permits.
• Follow ADGAS Emergency Procedure and be aware about the nearest and safest Marshalling
Point.
• Hold workplace talk prior to commencement of work and discuss the Task Risk Assessment
content.
• Check all equipments/tools for safety and soundness prior to use at site.
• Maintain close work supervision.
• Heat stress arrangement, SIMOPS and personnel evacuation to be checked.
• SIMOPS.
• ERP.
