The risk assessment matrix is used to assess whether and how much risk is involved in the work to be performed. It helps in identifying the potential risk involved in any work.
The risk matrix shows the severity and likelihood of the hazards of any task through rating. The rating of what is a risk can be found by multiplying the severity and probability of the task.
Risk Assessment Matrix
Low Risk ( 1 to 4 )
Manageable and minor which can control easily.
Moderate risk ( 5 to 8 )
Efforts should be made to reduce the risk as much as possible by further reducing it. Manageable risk with identified controls.
High risk ( 9 to 12 )
Unacceptable risk to work. Urgent action is needed to reduce the risk. Significant controls are needed to reduce the risk.
Extreme Risk ( 15 to 25 )
intolerable risk. In this type of risk, work should be stopped, and immediate action needs to be taken to reduce the risk. Implement significant risk control measures to reduce the magnitude of risk to the lowest possible level.
| Activity | Risk | Likelihood (1 to 5) | Severity (1 to 5) | Risk Rating (LxS) | Control | Final Risk |
|---|---|---|---|---|---|---|
| Pest Control | Respiratory hazards | 3 | 3 | 9 ( High Risk ) | 1. Respiratory Mask 2. Chemical Gloves 3. Work Process Document (SOP) | S2 x L2 = 4 (Low Risk ) |
