OSSCL Risk matrix will be used to determine the potential risk of an accident/incident in order to ensure an appropriate level of investigation is conducted. The HSSE department along with the Department Supervisor will determine the severity of an accident.
The actual severity of an incident shall be considered according to its impacts on each of the three hazard categories (people, property/equipment damage-monetary value impact and environment), with the severity rating duly assigned to each. The more severe the outcome of an incident, the higher the numbers should be. The detailed definitions behind the summarized quotes on OSSCL’s risk matrix can be seen in the Risk Management Procedure.
To determine the potential risk of an incident using OSSCL’s Risk Matrix, follow the four simplified steps below
|
|
Step 1 | Determine a potential severity rating from 1 to 5.
|
Step 2 | Using all available historical information, determine a potential likelihood from 1 to 5. This figure refers to the likelihood of the potential severity (not the actual severity) occurring.
|
Step 3 | Repeat the steps above separately for each matrix hazard category.
|
Step 4 | The product of the severity rating and the likelihood rating should then be calculated and assigned to the Risk section.
Potential Risk = Likelihood x Severity
|
Level of Investigation | Personnel Involved |
Trivial- Tolerable Risk | Supervisors/Manager |
Substantial Risk | Supervisors, Managers, HSSE Advisor and Joint HSSE Committee |
High risk | Senior Management Representative, Supervisors, Managers, HSSE Advisor and Joint HSSE Committee |
Where the circumstances determine the need of a specialist/technical person, management will appoint same.
