Hazard Assessment

A valuable part of a health and safety program is an effective method or system of identifying and controlling hazards in the workplace. A workplace hazard can be any activity, condition, or substance that has the potential to harm a worker. Hazards are generally divided into two categories: safety hazards and health hazards.

Tasks that expose workers to a high degree of personal risk require special planning. For these tasks, the Joint Health and Safety Committee, the Health and Safety Representative, management, and affected workers, as applicable, should complete a job or task hazard analysis. The analysis and precautions to control or reduce the hazard must be communicated to workers prior to performing the tasks.
