Incorporation of inherently safer design principles in process safety assurance: Association with risk assessment and use of risk-based approach

Research output: Contribution to journalConference articleScientificpeer-review

Abstract

Inherently safer design (ISD) is a proactive approach in which hazards are eliminated or lessened so as to reduce risk with decreased reliance on engineered (add-on) safety devices and procedural measures. Four basic principles can lead to an inherently safer design - minimization, substitution, moderation and simplification. The main idea of this study is the application of all four principles to key areas of process safety management. Discussions are provided on how to link risk assessment with the implementation of ISD design principles in process safety management. A risk-based approach framework is also developed to support the selection of alternative ISD options. The ultimate objective is to provide a bridge between inherent safety principles and new strategies for process safety assurance. The motivation for this work stems from the gap that exists between accepted theory (the hierarchy of risk control measures) and industrial practice.
