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.

  • Up to date site layout diagram/ process flow sheets for identification of activities
  • All activities where previous records of Incidents, Accidents occurred.
  • Inputs from regular Plant & Management Review meetings/ Safety inspections/ records.
  • All routine activities (those activities which are scheduled & carried out frequently)
  • All non-routine activities (those activities which are not done in scheduled time or done occasionally)
  • Examination of all existing OHS procedures and practices.
  • Activities of all personal having access to work place (including sub contractors & visitors).
  • Facilities at the work places, whether provided by the organization or others.
  • Material Safety Data Sheets to identify the possible OHS Hazards
  • Past OHS monitoring and health data.
  • Records of safety audits.
  • Records of correspondence with legal & regulatory bodies.
  • Previous records of incidents or accidents if any.
  • Prevailing applicable Acts and legislation.
  • Facility layout chart
  • Equipment Manufacturers Documents / IS codes for corresponding electrical equipment
  • Accidental hazards (such as slip/ trip/ fall/ struck by/ hit by etc. due to unsafe conditions/ practices)
  • Electrical hazards
  • Fire hazards
  • Mechanical hazards
  • Physical hazards (including Radiological hazards)
  • Chemical hazards
  • Biological hazards
  • Ergonomic hazards
  • Any other issue as relevant
