Hazard Identification, Risk Assessment and Risk Control (HIRARC) HAZARD IDENTIFICATION A source or situation with a potential for harm in terms of injury or ill-health, damage to property, environment or a combination of the above. DANGER - Relative exposure to the hazard Risk: The likelihood that a specified undesired event will occur due to the realisation of a hazard by, or during work activities or by the products and services created by work activities. Assessing the Risks Quantitative risk assessment *Commonly used in the high technology industries - Qualitative risk assessment involves making a formal judgement on the consequence and probability using: Risk = Severity of harm x Likelihood of occurrence RISK A combination of the likelihood of an occurrence of a hazardous event with a specified period or in specified circumstances and the severity of injury or damage to the health of people, property, environment or any combination of the above Purpose of HIRARC • to identify all the factors that may cause harm to employees and others (the hazards). • to consider what the chances are of that harm actually being falling anyone in the circumstances of a particular case and the possible severity that could come from it (the risks). • to enable employers to plan, introduce and monitor preventive measures to ensure that the risks are adequately controlled at all times. HIRARC activities shall be plan and conducted – a. for situation – i. where hazard appear to pose significant threat; ii. uncertain whether existing controls are adequate; or/and iii. before implementing corrective or preventive measures. b. by organization intending to continuously improve OSH Management System. Documenting process Instructions to team leader and persons conducting HIRARC – 1. Complete HIRARC Form. It is recommended to use a single form for each work process; 2. Record the names and designation of HIRAC team members; 3. Outline the process workflow and indicate in the form under ‘process/ location column; 4. List all activities ( routine and non-routine) for each work process under the “Work Activity” column; 5. Identify the hazards associated with each activity and record in “Hazard” column; 6. Determine the effect of each hazard identified and record in “Effect” column; 7. Record any existing hazard control measures; 8. Determine likelihood (L) and severity (S) from each hazard (Refer tables). Assign the rating in each column. The existing control measures should be taking into consideration while determine (L) and (S); 9. By using Risk Matrix ( refer table ) assign one risk and record in “Risk” column; 10. Based on the risk assigned, recommend appropriate risk control measures 11. Assign a suitable person to implement the recommended risk control and indicate the follow up action date and status; 12. Repeat the HIRARC for other activities and process; 13. Conduct another round of HIRARC after control measures have been implemented; 14. Review HIRARC for every three years or whenever there are changes in process or activities. SEVERITY RATING LIKELIHOOD RATING DETERMINE THE RELATIVE RISK: Relative Risk = Likelihood (L) x Severity (S) *To use this matrix, first find the severity column that best describes the outcome of risk. *Then follow the likelihood row to find the description that best suits the likelihood that the severity will occur. *The risk level is given in the box where the row and column meet.
