OSHA's Compliance Guidelines and Recommendations for the PSM Standard states "A PHA is an organized and systematic effort to identify and analyze the significance of potential hazards associated with the processing or handling of highly hazardous chemicals."1 It goes on to say "A PHA is directed toward analyzing potential causes and consequences of fires, explosions, releases of toxic or flammable chemicals and major spills of hazardous chemicals."1 OSHA does not give any additional guidance; they just refer you to 18 additional "Sources of Further Information". I would like to present a process on how to develop scenarios (causes and consequences), tips on creating credible and realistic scenarios and the pitfalls to avoid during the process, commonly encountered during a PHA.

Process safety information (PSI) needs to be evergreen and must contain the relief system design and design basis per OSHA 1910.119. Cooling water is used as a cooling medium in heat exchangers, often on the low-pressure side. During analysis of overpressure scenarios on the low-pressure side, there is often times debate about the quantity of relief credit that can be taken for flow out of the protected system and into the cooling water network. Current industry practice offers guidance that is generic and might be applied incorrectly without appropriate relief systems knowledge. This paper provides a flowchart-based approach and methodology that can be used for qualifying and quantifying relief credit through the cooling water side of heat exchangers. Source

API 520 Part I & API 521 provide guidance for designing emergency relief devices for the external pool fire scenario for pressure vessels built to ASME Code Section VIII, Div.1. Current API standards provide vapor generation and/or two-phase flow sizing models assuming that the relief valve is installed in the top of the vessel. ASME Code Section VIII, Div.1, UG-135, provides guidance in the installation of the relief device. However, the current standards do not limit the location of relief devices to only the top of the vessel. Certain pressure vessels, such as filters or vertical heat exchanger shells may have relief devices installed at a location below the liquid level for maintenance access, space limitations, or piping constraints. The use of traditional sizing methods can grossly undersize the valve as the relief device will need to pass fluids at a rate equal to the volumetric rate of vapor generated by the fire. Existing literature provides limited guidance on sizing and disposal requirements. This paper provides general guidance, sizing method strategies, mitigation, and design of relief devices used in such services. Source
