Risk Assessment for Testing Pre-Commissioning & Commissioning of Generators

 

BASIC JOB STEP / ACTIVITY POTENTIAL ACCIDENT OR HAZARD Initial Risk Rating Probability x Severity Risk Factor CONTROL  MEASURES / MITIGATION  ACTIONS Final Risk Rating Probability x Severity Residual Risk Factor Risk Acceptable
1 Electrocution 2 3 6 Electrocution – Only suitably experienced/qualified competent personnel to be used to carry out testing.  1 3 3 Low
2 Fall from height May cause death or permanent disability 2 3 6 1. Use of PPE and safety belts 2. Tool talks and trainings to workers.  3. Combination stepladders to be fully extended & operatives will not to use the top three steps alternatively podium towers may be used. 4. Inspections to take place before use. 1 2 2 Low
3 Working with rotating machinery May cause death, permanent disability or bodily injury 3 3 9 Permit to work, Controlled issue of keys 1 2 2 Low
4 Testing & Commissioning of Generator  Risk of scalding and burns 2 3 6 -care to be taken when working on generator plant, Gloves to be worn where required. 1 2 2 Low
5 Testing & Commissioning of Panels potential to electric shock, death/Serious injury 2 3 6 Only trained & experienced persons performed testing & commissioning 1 2 2 Low
6 Scaffolding, ladder & false work Collapse of Scaffolding, ladder & false work 2 3 6 Regular periodic inspection & certification for safe to use tag shall be used for scaffolding & ladder and instruction boards for uses 1 2 2 Low
RISK FACTOR MATRIX
 

 

Probability4 -Probable-Likely to occur immediately or shortly 3 -Reasonably probable-Probably will occur in time. 2 -Remote-May occur in time 1 -Extremely remote–Unlikely to occur Severity4 – Catastrophic – Imminent danger exists, hazard capable of causing death and illness on a wide scale3 – Critical – Hazard can results in serious illness, severe injury, property and equipment damage 2 – Marginal -Hazard can cause illness, injury or equipment damage, but ht results would not b expected to be serious 1 – Negligible – Hazard will not result in serious injury or illness, remote possibility of damage beyond minor first aid case.

Probability RISK PRIORITY  

Methodology1. Identify Hazards 2. List Hazard Event 3. Calculate risk factor with initial risk rating i.e., probability x severity 4. Detail controls 5. Calculate residual risk factor with final risk rating 6. Enter risk priority 7. Evaluate acceptability of risk

s e v e r i t y 4 3 2 1 8-16 High Risk
4 16 12 8 4 6 Medium Risk
3 12 9 6 3 1-4 Low Risk
