Hazard Identification Formula: Risk × Exposure

Formula

Hazard = Risk × Exposure

The severity of a hazard is determined by the likelihood of an adverse event (risk) multiplied by the extent to which people or property are exposed to it.

Example

• High hazard: High risk of a chemical spill in an area with many workers.
• Lower hazard: Low spill risk with only a few workers present.

Purpose

Identifying and assessing hazards allows organizations to develop appropriate controls to prevent or mitigate harm.
