Hazard control

Once the hazards have been corrected, the employer, in collaboration with the workers, must ensure that they remain under permanent control. This is the step of the prevention process that is most often neglected, resulting in repeated work accidents in companies.

To avoid going back to square one, it is important that preventive measures remain in place and remain effective.

How to proceed

To control hazards effectively, the employer must:

  1. identify and describe a minimum of 2 appropriate controls for each preventive measure chosen
  2. include these controls in the template or prevention program, indicating:
    • the controls in place or to be implemented
    • the target completion date or frequency
    • the people responsible


The employer must ask the following questions:

  • How do I verify that what I have done, stays done (inspection, maintenance, training reminders, etc.)?
  • How can we avoid introducing new hazards when implementing corrective measures (purchasing policy, training of new employees, etc.)?

The following is a list of controls that can be put in place:

  • preventive maintenance
  • training, refresher training
  • information
  • inspection
  • purchasing policy
  • engineering policy
  • outsourcing policy
  • supervision
  • workplace quality monitoring
  • worker health monitoring

It is recommended that evidence or documentation be kept at all stages of the prevention process. For example, photos taken before and after the corrective and control measures are implemented.
