Likelihood – Possibility of occurrence of risks based on present gaps (technological / operational / competence / measurement and monitoring);
Level of consequence– Refer Guidance criteria for this i.e. possible degree of damage; LC – Legal Concern - if identified OHS hazards are risks is governed by Indian OHS Legislation, DC – Domino Concern– Source or Situation can Trigger of Chain of Accidents, Non-Tolerable OHS Risks Measures –
The Substantial and Intolerable risks shall be treated as non-tolerable OHS risks, requiring risk control measures (Management Programme / OCP / Both / Emergency preparedness plan / obvious improvement / training OR competence development)
A.3 DETERMINING RISK LIKELIHOOD – GUIDANCE CRITERIA
Likelihood | Criteria |
Highly Unlikely (1) | If almost no gap exists in control of the identified OHS hazard as technology, operational control,competence,measurement monitoring in place |
Unlikely (2) | If there is any minor gap / weakness in control of the identified OHS hazard |
Likely (3) | There are unreasonable gaps in control of the identified OHS hazard with respect to adoption of technology, operational control, measurement monitoring and competence |
Very Likely (4) | There are unreasonable major gaps in control of the identified OHS hazard with respect to adoption of technology, operational control, measurement monitoring and competence |
Certain (5 ) | There are almost no controls in place in controlling the identified OHS hazard and have occurred in the past but ignored. |
4 DETERMINING RISK CONSEQUENCY LEVEL – GUIDANCE CRITERIA
Level of Harm | Human | Property | Exposure level | |
Insignificant (1) | Momentary Discomfort/ inconvenience | No action required | Below / equal to prescribed TLV (8 hrs) | |
Slightly Harmful (2) | Minor injuries (Non reportable) requires first-aid | Minor damage | Above than prescribed TLV (8 hrs); However < 20% | |
Harmful (3) | Injuries, absence from the work less or equal to 48 hrs / temporary disability/ Medical Treatment Cases | Moderate damage | Above than prescribed TLV (8 hrs); However within 20% - 40% | |
Very harmful (4) | Major injuries, absence from the work more than 48 hrs / temporary disability/ Lost Time Injuries | Severe damages | Above than prescribed TLV (8 hrs); however within 40-50% | |
Extremely Harmful (5) | Fatal / Permanent Disability. Major incidents involving large number of people | Annihilation (complete destruction) | Above than prescribed TLV (8 hrs); AND > 50%, leading to chronic notifiable disease | |
NOTE : TLV (8 hrs) As may be prescribed in The Factory Act 1948 & Equivalent Standards

A.6 DEFINITION OF LEVEL OF IMPACT / RISKS (REFERENCE IS 18001:2002)
Risk Level | Action and Time Scale |
TRIVIAL | No action is required and no documentary record needs to be kept. |
TOLERABLE | No additional controls are required. Consideration may be given to a more cost-effective solution or improvement that imposes no additional cost burden. Monitoring is required to ensure that the controls are maintained. |
MODERATE | Efforts should be made to reduce the risk, but the cost of prevention should be carefully measured and limited. Risk reduction measures should be implemented. |
SUBSTANTIAL | Work should not be started until the risk has been reduced. Considerable resources may have to be allocated to reduce the risk where the risk involves work in progress, urgent action should be taken. |
INTOLERABLE | Work should not be started or continued until the risk has been reduced. If it is not possible to reduce risk even with unlimited resources, work has to remain prohibited. |
A.7 INPUTS TO BE CONSIDERED DURING THE IDENTIFICATION OF OHS HAZARD AND RISK
Core team along with departmental managers to consider following input information for hazard identification / risk assessment purposes.
