Which standard does not establish material requirements for check valves in the Emergency Oxygen Supply Connection?

• A. NFPA 70
• B. NFPA 93
• C. NFPA 99
• D. NFPA 101

Answer: (C)

The main idea here is where the standards specify the actual materials that components must be made from. For the Emergency Oxygen Supply Connection, check valves must be compatible with oxygen service and meet the requirements for medical gas equipment, but not every standard does this in terms of exact materials. NFPA 99 focuses on safety management, operation, testing, and maintenance of health care facilities and their medical gas systems. It governs how the system is run and verified, but it does not prescribe the precise materials that check valves must be made from. That kind of material specification is handled by standards that address the equipment itself and oxygen-service compatibility, rather than the facility-wide safety program. So NFPA 99 is the standard that does not establish those material requirements.
