4.1 Hazard

Source with a potential to cause injury and ill health, including physical, chemical, biological, ergonomic, and psychosocial factors.

4.2 Risk

A concept that combines the probability of exposure to hazards and the severity of resulting injury or ill health.

4.3 Risk Assessment

The overall process of identifying hazards and analyzing and evaluating related risks.

4.4 Acceptable Risk

Risk that has been reduced to a level that can be tolerated by the organization having regard to its legal obligations and HSE policy.

4.5 Residual Risk

Risk remaining after risk treatment measures have been implemented.
