Human Health Risk Assessment (HHRA) evaluates potential health effects from workplace hazards by identifying risks, assessing exposure levels and outcomes, estimating worker exposure, and characterizing overall risk. This helps employers determine if workplace conditions pose significant health risks to employees.

Conducting HHRA is essential for preventing occupational illnesses by identifying and mitigating risks early. It underpins the development of workplace health regulations and safety standards, guides risk management decisions, and ensures resources are allocated effectively.
