The effectiveness of controls must be checked regularly. Evaluate and monitor hazard controls during inspections, routine maintenance, and other activities. Ask the following questions :
- have the controls solved the problem?
- is any risk to workers posed by the controls contained?
- are all new hazards being identified?
- are significant, new hazards appropriately controlled?
- are accident reports being analyzed?
- are any other measures required?
Document control activities to track their effectiveness, if necessary re-evaluate hazards and implement new control measures.
