Safety hazard mitigation is consequent to process hazard analysis of a chemical process project; this is most frequently done using HAZOP (Hazards and operability study). HAZOP is a systematic, thorough method, using the Process Flow Diagrams, and it is designed, ideally, to find all possible specific unsafe conditions. Hazard mitigation addresses the hazards and consequent possible unsafe events identified by the HAZOP, including their probability and their consequence magnitude. It eliminates the hazard or reduces its probability and/or consequences to an acceptable level. It seeks to prevent the fatalities, injuries, illness, property damage, interrupted production and the attendant financial costs from inadequately prevented and controlled safety hazards.
Hazards mitigation is designed to protect the employees, contractors, site visitors and the public. Regular employee and contractor training in the specific process hazards and their mitigation is essential. This includes Management of Change, OSHA, EPA, DOT and DOE requirements, and mandatory Process Hazard Analysis updates every 5 years. Mitigation uses Inherently Safe Process Design, engineering controls (e.g. interlocks), personal protective equipment (e.g. respirators) and operating procedures, written for safe operation by documenting all the safety hazards and how they have been addressed. The operating procedures must ensure safe start up, normal operation, normal shut down and emergency shut down.
