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

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.
