OHS prevention program: what it must contain (20 workers or more)

The prevention program is the core health and safety tool for organizations with 20 people or more. Done well, it is a real management tool, not one more binder on a shelf.

Who needs a prevention program?

Since Québec modernized its occupational health and safety regime, workplaces with 20 workers or more must have a prevention program. They also set up a joint health and safety committee and have a health and safety representative (RSS).

Smaller workplaces use an OHS action plan instead, with a health and safety liaison officer.

The essential elements

  • An OHS policy and management commitments, adopted and signed
  • Roles and responsibilities: management, managers, human resources, the committee, the representative, staff, contractors
  • Identifying, assessing and prioritizing risks: physical, chemical, biological, ergonomic, psychosocial and safety risks
  • Prevention measures chosen according to the hierarchy of controls and gathered in an annual action plan
  • Planned workplace inspections
  • Health and safety onboarding, training and information
  • Managing accidents and incidents: reporting, log, investigation and follow-up
  • Emergency measures and first aid
  • Preventing harassment and violence
  • Monitoring, indicators and program review

The committee and the representative

The joint committee helps identify risks, makes recommendations to the employer, plans inspections and reviews investigation reports. The representative inspects the workplace, takes part in investigations, makes recommendations and can accompany the CNESST inspector.

Time spent on these duties is paid, and both are protected against any form of reprisal.

Psychosocial risks are now a must

The program must treat psychological health like physical health: workload, recognition, support, role clarity, civility, violence and harassment. The approach works on three levels: act on the sources, equip people and support those who are affected.

Common mistakes

  • A document copied from another organization, unrelated to its actual risks
  • A risk inventory that is never updated
  • Psychosocial risks left out or reduced to a harassment policy
  • A committee that does not meet, or whose recommendations go nowhere
  • No record of training, inspections or investigations

How often should it be reviewed?

At least every three years, and after any significant change, serious accident or CNESST recommendation. An annual report to management helps track indicators and the progress of the action plan.

Frequently asked questions

Does my 25-employee business need a prevention program?

Yes. A workplace with 20 workers or more must have a prevention program, a health and safety committee and a health and safety representative.

Is a template enough?

A template is a good starting point, but the program must reflect your workplace’s actual risks, be applied and be kept up to date. That is what matters during an inspection.

Must psychosocial risks be in the program?

Yes. They must be identified, analyzed and controlled just like physical risks.
