Hazard Identification, Risk Assessment, and Control ...

Risk assessment is the process of evaluation of the risks arising from a hazard, taking into account the adequacy of any existing controls and deciding whether or not the risks is acceptable. It is impossible to eliminate all hazards, so the goal is to eliminate and/or control the hazards with critical and high potential risk to the lowest reasonable risk level so as to protect workers from harm.
