P-28: OSHA Process Safety Management and EPA Risk Management Plan Guidance Document for Bulk Liquid Hydrogen Supply Systems

The U.S. Occupational Safety and Health Administration (OSHA) Process Safety Management (PSM) standard and the U.S. Environmental Protection Agency (EPA) Risk Management Program (RMP) rule require that some U.S. industrial gas facilities comply with these regulations. For the purpose of this publication, OSHA PSM refers to Title 29 of the U.S. Code of Federal Regulations (29 CFR) Part 1910.119, “Process Safety Management of Highly Hazardous Chemicals”, and EPA RMP refers to Title 40 of the U.S. Code of Federal Regulations (40 CFR) Part 68, “Chemical Accident Prevention Provisions”.

This publication is designed to help owners and operators of liquid hydrogen bulk tanks comply with PSM and RMP rules in addition to the requirements of CGA H-5, Standard for Bulk Hydrogen Supply Systems (an American National Standard). CGA H-5 refers to NFPA 55, Compressed Gases and Cryogenic Fluids Code, for the minimum setback distances between bulk hydrogen systems and exposures. The distances for worst-case release scenarios in 7.3 and alternative release scenarios in 7.4 of this publication are not intended to replace the NFPA 55 setback distances.

More details about the application of OSHA PSM and EPA RMP to hydrogen supply systems and other com-pressed gas and cryogenic fluid systems can be found in CGA P-29, Guideline for Application of OSHA PSM and EPA RMP to the Compressed Gas Industry.
