This document provides a step-by-step hazard management tool to help workplaces recognize, assess, and control workplace hazards. It was developed by several Ontario health and safety organizations. The tool involves recognizing hazards, assessing their likelihood and severity of harm, establishing control priorities, implementing controls, and ongoing evaluation of hazards and controls. Effective hazard management requires a team approach and supports Ontario's Internal Responsibility System which makes all parties responsible for workplace health and safety.
