Determine tolerability of risks:
Category of risk |
Evaluation of tolerability |
Very low |
Acceptable |
Low |
Tollerable |
Medium |
Risks should be reduced so that they are tolerable or acceptable |
High |
|
Very high |
Unacceptable |
Details:
Very low risk: Considered acceptable. No further action is necessary other than control measures are maintained.
Low risk: No additional control measures necessary. Actions to further reduce these risks considered low priority.
Medium risk: Consideration to be given where risk can be lowered to a tolerable level and preferably, acceptable level.
High risk: Substantial efforts should be implemented urgently to reduce the risk.
Very high risk: Considered unacceptable. Substantial improvement in risk control measures is necessary to reduce risk at tolerable or acceptable level.
