NFPA | 2023 | 157 |
Help improve industrial safety around compressed gases and cryogenic fluids with the latest edition of NFPA 55, Compressed Gases and Cryogenic Fluids Code. Working with and around industrial gas calls for a specialized skill set and understanding of general operating and safety requirements. The 2023 edition of NFPA 55, Compressed Gases and Cryogenic Fluids Code, demonstrates how to mitigate physiological, over-pressurization, explosion, and flammability hazards relating to these highly combustible materials in all types of occupancies. This NFPA® publication is essential for everyone from installers, contractors, and engineers to code enforcers, inspectors, and environmental health and safety personnel. NFPA 55 provides comprehensive coverage of the fundamentals for safer and more effective installation, storage, use, and handling of gases in portable and stationary containers, cylinders, equipment, and tanks. Code content covers: General requirements for emergency readiness and response Classification of hazardous materials Building control areas and fire and hazard protection systems Storage, use, and handling of compressed gases and cryogenic fluids Bulk oxygen, gas hydrogen, bulk liquefied hydrogen, gas generation, and carbon dioxide systems Storage, handling, and use of ethylene oxide for sterilization and fumigation General requirements and special considerations for acetylene cylinder charging plants Provisions and maintenance procedures for liquid nitrous oxide systems Cryogenic fluid central supply systems in health care facilities Be confident you have the most current information you need to stay code-compliant and help safeguard lives and property. The 2023 edition includes the following changes: Updates to clarify the proper doubling allowances associated with cabinet storage Expanded flammable gas requirements to include refrigerants with lower global warming potential Expansion of the definition for flammable gas to include Category 1A and Category 1B flammable gases, which have been added to the table in Chapter 6 on the maximum allowable quantity (MAQ) of hazardous materials per control area Revised requirements to reduce the risk of excessive stacking of small cylinders and to clarify the proper electrical classification of gas cabinets Revised temperature extreme requirements for compressed gas cylinders to account for manufacturers with facilities that expose cylinders to sub ambient temperatures during filling New requirements for bulk hydrogen gas system installations in 3- and 4-walled enclosures or courts
