The Application of Bow Ties for a Robust PSM Program

Abstract

The fourteen elements of OSHA’s Process Safety Management (PSM) program underpin so much of facility operations. PSM programs grow in complexity over time and can become increasingly disembodied from the operational elements that form their robustness. Often new PSM programs are modeled from organically grown existing programs rather than tailored to the specific risks of the operation introducing more than necessary complexity from the beginning. Barrier-based approaches can revitalize an existing PSM program or serve as a platform to build a simplified PSM program. Bow ties reestablish direct connections to operations in a quickly visualized way transforming the perception of a PSM program from an operational albatross into an engagement tool to inspire ownership at all levels of the organization. This paper walks through each of the fourteen PSM elements highlighting the application and value of applying a barrier-based approach to the development or implementation of a PSM program. Whether working with a robust PSM program that has become more complex over time or building a simple program based on the broad PSM concepts, bow ties can help a company focus their efforts on efficiently addressing deficiencies in their management systems and managing their most important risks.
