Inherent Safety & the Elements of a RBPS Program

This chapter describes the relationship between the four main inherent safety (IS) strategies, i.e., substitution, minimization, moderation, and simplification and each element of a process safety management/risk-based process safety (PSM/RBPS) program. The four IS strategies are usually applied in the context of the chemicals and the hazards/risks that they present, e.g., substituting one chemical with another that presents less of a process safety hazard, or minimizing the inventories of the chemicals that can create process safety hazards. Conduct of Operations is a PSM/RBPS element that covers a broad range of process safety program activities. The relationship between process safety culture and IS is close. The quality assurance portion of an asset integrity program is often where the traditional uses of IS strategies are employed because it is the when equipment is designed. Management of Change is required to be used whenever IS changes to existing equipment are being proposed.
