Determine how NFPA 99 and NFPA 55/CGA requirements interact for a bulk oxygen supply system at a health care facility

Steps

1. Confirm NFPA 55 (Compressed Gases and Cryogenic Fluids Code) governs bulk oxygen system siting/storage generally, defining a bulk oxygen system as an assembly with a storage capacity greater than 20,000 SCF terminating at the source valve
2. Confirm NFPA 55 Chapter 17 addresses cryogenic systems specifically in health care facilities but requires compliance with the general provisions in NFPA 55 Chapters 1-16 as well
3. Confirm NFPA 99 governs the health-care-facility-specific piping distribution, alarms, EOSC, and use requirements once the bulk source terminates at the source valve
4. Confirm CGA publishes supporting technical pamphlets/standards (e.g., relevant to bulk oxygen system design and cleanliness) that are commonly referenced by both NFPA 55 and NFPA 99 as supporting technical guidance — verify the specific CGA document number relevant to the project scope rather than assuming a single blanket CGA reference
5. Confirm siting requirements (distances from buildings, combustibles, paving materials, etc.) with the local fire marshal/AHJ, since bulk oxygen storage siting is a fire-code (NFPA 55) function coordinated with, but distinct from, the healthcare-facility code (NFPA 99)
