If you feel unsure about any of the above, and have reasonable cause, you need to stop and inform your supervisor of your concerns.
Reasonable cause means a worker has an honest belief, based on objective facts that a situation presents a danger to their health or safety, and that belief would be shared by a reasonable person in the same situation.
Dangerous work can include any of the following:
- Lack of PPE such as not having the correct respirator cartridge to work around hazardous products or not having PPE at all when using a chemical
- Equipment that is faulty or defective, such as a scaffold missing a toe board.
- Working at heights with out fall protective equipment
- Working alone at night in a high crime area with no security measures
- Working outdoors in extreme heat or extreme cold
- Being untrained for a task, such as using a forklift

Each jurisdiction outlines similar processes for exercising the right to refuse:
- Identify and stop the task when dangerous work is identified.
- Report the concern to your supervisor or whomever company process requires.
- Employer investigates the concern, often with the involvement of the health and safety committee or health and safety representative.
- If the concern is not addressed, the issue is escalated to the provincial authority, who will investigate and provide a written decision.
- Perform safe work or appeal the decision.
