What is the maximum allowed central supply temperature for nitrous oxide?

• A. -20°F
• B. 32°F
• C. 125°F
• D. 0°F

Answer: (C)

Keeping the central supply temperature within a safe limit is essential to protect gas quality and system safety. Nitrous oxide can degrade if it gets too hot, and heating raises pressure in the distribution network, increasing the risk of equipment failure or leaks. That's why there is a defined maximum: 125°F. This limit helps prevent decomposition or excessive pressure while still allowing normal operation. The other temperatures listed are too cold to be the maximum and would not address the safety concern of overheating.
