The next stage after the hazard has been identified is to carry out risk analysis and assessment. When carrying out risk analysis and assessment the parameters used are CONSEQUENCES and OPPORTUNITIES (frequency). Consequences are the possible severity of an incident involving people, property, the environment or the company’s reputation.
Example:
- Which results in humans such as fatal, disability, medical treatment, first aid.
- Which resulted in property such as damage to factory facilities.
Opportunity is the frequency of occurrence of an incident which is usually expressed in units of time.
Example:
- Never happened to a similar company
- This has happened to this company
- This has happened several times a year
Some of the references used in risk assessment are information about work activities, control measures that have been carried out, equipment used, accident statistical data, etc.
Types of risk analysis are divided into Qualitative, Semiqualitative and Quantitative. Qualitative is analyzing and assessing risks by comparing the parameters of consequences and opportunities by comparing predetermined matrices. The semiquantitative method used is almost the same as the quantitative method, the difference lies in a certain value/score that has been determined according to the risk. Quantitative is done by determining the value of each parameter which is obtained from the results of representative analyzes such as statistical analysis, simulation, fault tree analysis, etc.
Risk Management
Next, it is determined whether the risk is acceptable (acceptable risk) or unacceptable (non-acceptable risk). If the risk is unacceptable, the company must determine corrective steps to the lowest risk using the control hierarchy principle:
- Elimination
- Substitution
- Manipulation
- Administration
- Personal Protective Equipment
Monitor and Review
Risk management that has been determined must always be monitored, whether it is in accordance with the implementation in work activities, if not, a review or review must be carried out and it is ensured that it is always updated.
