1. Which code primarily governs medical gas and vacuum systems in
healthcare facilities?
A. IPC
B. UPC
C. NFPA 99
D. NEC
Rationale: NFPA 99 is the Health Care Facilities Code that establishes
requirements for medical gas and vacuum systems.
2. Medical gas piping systems must be installed using materials that are:
A. Galvanized steel
B. Copper tubing, type K or L
C. PVC
D. Black iron
Rationale: NFPA 99 requires Type K or L copper tubing for medical gas
systems due to cleanliness and strength.
3. Which gas is considered a medical vacuum system component?
A. Oxygen
B. Nitrous oxide
C. Medical vacuum
D. Carbon dioxide
, Rationale: Medical vacuum is a distinct system used for suction and
evacuation.
4. What brazing alloy is required for joining medical gas copper tubing?
A. 15% silver
B. 35% or higher silver content
C. Lead-based solder
D. Tin solder
Rationale: High-silver brazing alloys ensure strong, clean joints suitable
for medical gas systems.
5. During brazing of medical gas piping, the tubing must be:
A. Filled with compressed air
B. Left open to atmosphere
C. Purged with nitrogen
D. Purged with oxygen
Rationale: Nitrogen purging prevents oxidation and contamination inside
the tubing.
6. Which document must be provided after completion of a medical gas
installation?
A. Plumbing permit
B. Verification and test reports
C. Manufacturer warranty
D. Inspection checklist only
Rationale: Verification and test reports confirm system integrity and
compliance.
7. Who is authorized to perform final verification testing of medical gas
systems?
A. Installer
B. Facility maintenance staff
C. ASSE 6030 certified verifier
D. General inspector
Rationale: NFPA 99 requires verification by a certified medical gas verifier.
8. What color is used to identify oxygen piping?
A. Yellow
, B. Green
C. Blue
D. White
Rationale: Green is the standardized color for oxygen identification.
9. Medical gas piping must be labeled:
A. Only at source equipment
B. Every 100 feet
C. At intervals not exceeding 20 feet
D. Only at outlets
Rationale: Frequent labeling ensures safety and proper identification.
10.Which pressure is typical for oxygen distribution systems?
A. 25 psi
B. 50–55 psi
C. 100 psi
D. 150 psi
Rationale: Oxygen systems operate around 50–55 psi per NFPA 99.
11.Which gas is considered a medical air system?
A. Oxygen
B. Nitrous oxide
C. Medical air
D. Nitrogen
Rationale: Medical air is a specific system used for patient respiration.
12.What is the primary purpose of an alarm system in medical gas
installations?
A. Control gas flow
B. Provide warning of abnormal conditions
C. Reduce pressure
D. Purify gas
Rationale: Alarms alert staff to unsafe pressure or system failures.
13.Where must master alarms be located?
A. Mechanical room only
B. Patient rooms
C. Area of continuous supervision
