Question 3

When a new medical gas system installation is complete, the required sequence of testing before patient use is:

Accepted Answer

Pressure/leak test, then purity/concentration test, then labeling verification

Answer

NFPA 99 mandates pressure/leak testing followed by gas concentration verification and outlet labeling checks before any system is placed in service.

Question 4

What is the correct color code for a medical-grade Nitrous Oxide cylinder in the United States?
