What is the maximum allowable pressure drop across a zone valve when fully open in a medical gas distribution system?
Answer: 2 psig
NFPA 99 permits a maximum pressure drop of 2 psig across a fully open zone valve to ensure adequate gas flow to patient care areas.
When storing compressed gas cylinders, full and empty cylinders must be separated and stored how?
Answer: In separate areas with clear labeling indicating full or empty status
Full and empty cylinders must be stored in physically separate, clearly labeled areas to prevent accidentally using an empty cylinder in an emergency.
Under NFPA 99, a Level 1 medical gas system is defined as one that supports patients who are:
Answer: In danger of loss of life if gas supply is interrupted
Level 1 medical gas systems support patients whose lives depend on the continuous supply of medical gases, requiring the highest reliability standards.
Which of the following materials is NOT acceptable for use in medical oxygen piping systems per NFPA 99?
Answer: Galvanized steel pipe
Galvanized steel pipe is not permitted in medical oxygen systems because zinc coatings can react with oxygen and contaminate the gas supply.
An RMGA must ensure that after any repair to a medical gas piping system, which test is performed before returning the system to service?
Answer: Cross-connection test, pressure test, and purity test
NFPA 99 requires cross-connection testing, pressure testing, and gas purity testing before a repaired medical gas system is returned to service.
What is the correct method for identifying a suspected cross-connection between two medical gas systems?
Answer: Pressurize one system and close all others, then test outlets with a gas analyzer
The cross-connection test involves pressurizing one gas system while keeping all other systems at low or no pressure, then verifying gas identity at each outlet with an analyzer.
Which organization must be notified when a medical gas system alarm activates and the source of the alarm cannot be identified within a reasonable timeframe?
Answer: The facility safety officer and clinical staff responsible for patient care
When a medical gas alarm cannot be resolved quickly, the facility safety officer and responsible clinical staff must be notified to assess patient safety implications.
