1. Which standard governs medical gas and vacuum systems in U.S.
healthcare facilities?
A. NFPA 70
B. NFPA 99
C. NFPA 101
D. OSHA 1910
Answer: B. NFPA 99
NFPA 99 is the primary standard regulating healthcare medical gas and
vacuum systems. NFPA 70 is the National Electrical Code, NFPA 101 is the Life
Safety Code, and OSHA 1910 covers general industry regulations.
2. What is the first step in medical gas system verification?
A. Pressure testing
B. Purge procedure
C. Review of installation documents
D. Alarm testing
Answer: C. Review of installation documents
Verification begins with reviewing drawings, labeling, and installer
documentation to confirm the system is ready for testing.
,3. What is the primary role of a Medical Gas Verifier?
A. Install piping systems
B. Design medical gas systems
C. Independently verify compliance and safety
D. Maintain medical gas systems
Answer: C. Independently verify compliance and safety
The verifier's role is independent inspection and testing to ensure compliance
with standards such as NFPA 99. The verifier must be independent of the
installing contractor.
4. Which gas is typically supplied at 50–55 psi in medical gas systems?
A. Oxygen
B. Medical air
C. Nitrogen
D. Vacuum
Answer: B. Medical air
Medical air is commonly regulated at 50–55 psi for patient use. Oxygen is
typically supplied at similar pressures but the question specifies the gas most
commonly associated with this pressure range in general medical gas
discussions.
5. What is the purpose of a cross-connection test?
A. Measure flow rate
B. Verify alarm function
C. Ensure no gas lines are misconnected
D. Test pipeline pressure
Answer: C. Ensure no gas lines are misconnected
,Cross-connection testing confirms each outlet delivers the correct gas without
cross-contamination. The verifier pressurizes each gas to a unique pressure
and uses gas-specific gauges to identify mismatches.
6. The first verification test performed by the ASSE 6030 verifier on the entire
system is typically the:
A. Cross-connection test
B. 24-hour standing pressure test (or confirmation of the installer's standing
pressure test)
C. Medical air dew point test
D. Alarm activation test
Answer: B. 24-hour standing pressure test
The verifier confirms a 24-hour standing pressure test with each gas
pressurized to a unique pressure. This is the foundation for the cross-
connection test that follows.
7. Which standard specifically addresses professional qualifications for
Medical Gas Systems Verifiers?
A. ASSE 6010
B. ASSE 6020
C. ASSE 6030
D. ASSE 6040
Answer: C. ASSE 6030
ASSE 6030 is the professional qualifications standard for Medical Gas Systems
Verifiers. ASSE 6010 covers installers, ASSE 6020 covers inspectors, and ASSE
6040 covers maintenance personnel.
8. Verification must be conducted by a party that is:
A. Employed by the installer
B. Employed by the owner
, C. Independent of installation
D. Certified plumber
Answer: C. Independent of installation
Independence ensures unbiased verification results. The verifier cannot be
employed by or affiliated with the installing contractor.
9. When must verification occur?
A. Before installation
B. During installation
C. After installation and before use
D. After 1 year
Answer: C. After installation and before use
Systems must be verified after installation but before being placed into
clinical service.
10. What is the maximum allowable dew point for medical air per NFPA 99?
A. +32°F at 50 psig
B. 0°F at 50 psig
C. -4°F at 50 psig
D. -40°F at 50 psig
Answer: C. -4°F at 50 psig
NFPA 99 limits medical air dew point to a maximum of -4°F at 50 psig.
Readings above the limit fail and indicate dryer problems.
11. Per NFPA 99, the maximum allowable carbon monoxide concentration in
medical air is:
A. 2 ppm
B. 10 ppm
