5. HIRA CONCEPT AND METHODOLOGY:
Hazard Identification is a systematic process of examining each work area and work task for the purpose of identifying all the hazards which are ‘inherent’ in the activity/job.
Risk Analysis is a systematic process of appreciating the risks associated with each of these hazards identified so that the nature of risk can be understood. This includes the nature of the damage/harm that may result from the hazard, the severity of that damage/harm and the likelihood of this occurring.
Risk Control details out taking actions to eliminate safety and health risks as far as is reasonably practicable. Where risks cannot be eliminated, then implementation of control measures is required, to minimize risks as far as is reasonably practicable. Hazard: Anything (condition, practice, behavior etc.) that has potential to cause harm, including injury, disease, death, environmental, property and equipment damage. Few examples of various types of hazards are as under:
• Slips and trips • Workplace transport • Moving heavy object • Sharpening tools • Working at height • Manual handling • Noise • Electricity • Confined spaces • Fire
Risk: The likelihood, or possibility, that harms(injury, disease, death, damage) may occur from exposure to a hazard.
KEYWORDS
• Activity : It defines the basic work being carried out. • Concern : It defines the possible hazard that may occur
during carrying out the activity. • Impact explanation : It defines the consequence/loss that may occur
because of the hazard. • Probability Rating : It defines the chances of occurrence of a particular
hazard. • Severity Rating : It defines the extent of damage/loss in case a
hazard occurs.
HIRA Report of GAIL Gas Limited, CGD Network, Sonepat
CEIL/9530/15-16/HIRA/GAIL Gas Sonipat/AKS/20 Page - 9 - of 55
• Overall Risk Rating : It is overall figure of Probability Rating times the Severity Rating.
• Existing Control Measures : It defines those control measures which are already in place/existing to mitigate a particular hazard.
• Additional Control Measures : It defines those control measures which need to be taken over and above existing control measures to mitigate a particular hazard.
• Residual Risk/Impact : It defines the assessment of risk after the implementation of existing control measures and additional control measures, if required.
RISK MATRIX
The Risk Matrix defines various levels of Severity and Probability of Occurrence which are as under. The CEIL and GAIL Gas Team discussed and decided upon various levels as under:
Categorization of Probability of occurrence:
Probability of occurrence
Rating
Once in a year 1
Once in six months 2
Once in three months 3
Once in a month 4
Categorization of Severity:
Severity
Rating
No injury only material loss 1
Minor to moderate injury or health effects OR Minor asset damage
2
Moderate to severe injury or health effects OR Major asset damage
3
Permanently disabling injury or fatality OR complete loss of asset
4
The overall Risk Matrix is as under:

CEIL/9530/15-16/HIRA/GAIL Gas Sonipat/AKS/20 Page - 11 - of 55
Note:
After implementing Existing Control Measures and Additional Control Measures, if the Risk Ranking decreases to less than 4, the Residual Risk will be treated as Tolerable.
Even after implementing Existing Control Measures and Additional Control Measures, the Risk Ranking decreases but remains in the range of 4-16, the Residual Risk will be treated as Intolerable.
However, as ‘Fatality’ is considered as the most serious consequence, hence, if there is an Overall Risk of 4 wherein ‘Fatality’ is involved, such risk will still be treated as ‘Intolerable’.
Intolerable risks have been classified as having potential for single or multiple fatalities. For such risks where the hazard involves loss of human life, remedial action of some kind has to be undertaken. There are four ways of handling any type of risks:
• Terminate • Treat • Tolerate • Transfer
All operational risks fall under these four categories. Suitable mitigating measures are devised and implemented to contain the risks. For the risks which are intolerable, an Incident Management Plan is prepared and activities are carried out in case of an incident, the Incident Management Plan is activated. In no case, an activity related to intolerable risks are stalled merely because they are intolerable as there is a well-defined Incident Management Plan in place.
CEIL Team Leader carried out planning together with GAIL Gas Limited Noida and Sonipat HSE Coordinator in terms of Methodology, Team members, Time Schedule and Special requirements of the contract. Following points were considered.
i. Scope of HIRA Study ii. Special requirements of the contract iii. Type & nature of installation iv. Acceptance criteria v. Deployment Schedule
