Documentation of hazard and operability studies

Abstract

The recently enacted Clean Air Act Amendments of 1990 [1] and the proposed OSHA Process Safety Management Standard [2] both require that hazard evaluations be completed on all facilities that handle hazardous chemicals. Reports of the hazard evaluations must be kept on file and will be subject to inspection during an OSHA compliance audit. This paper outlines those concepts that are important in the preparation of the documentation of a Hazards and Operability (HAZOP) study.
