work?
A. Medical vacuum
B. Domestic sewage only
C. Storm drainage only
D. Building lighting
Correct Answer: A. Medical vacuum
Rationale: Medical gas systems can include medical vacuum, WAGD, USP gases, and support
gas piping.
6. What is the most important reason for maintaining medical gas piping
cleanliness?
A. To improve appearance
B. To prevent contamination of the gas supply
C. To reduce ceiling height
D. To increase room lighting
Correct Answer: B. To prevent contamination of the gas supply
Rationale: Contaminants such as oil, grease, dirt, and moisture can create serious hazards in
medical gas systems.
7. Why must oil and grease be kept away from oxygen piping?
A. They can create a serious fire or combustion hazard in oxygen-rich environments
B. They reduce pipe length
C. They improve brazing
D. They increase vacuum
Correct Answer: A. They can create a serious fire or combustion hazard in oxygen-rich
environments
Rationale: Hydrocarbon contamination is particularly dangerous in oxygen service.
8. What is the purpose of cleaning medical gas tubing before installation?
A. To remove contaminants
B. To increase pipe diameter
C. To change gas identity
D. To increase building pressure
, Correct Answer: A. To remove contaminants
Rationale: Clean tubing is essential to protect gas purity and system safety.
9. What should be used to protect cleaned tubing ends during storage?
A. Open air without protection
B. Suitable caps or plugs
C. Grease
D. Paint
Correct Answer: B. Suitable caps or plugs
Rationale: Ends should be protected from dirt, moisture, and other contaminants.
10. What is the purpose of nitrogen purging during brazing?
A. To prevent oxidation inside the tubing
B. To increase oxygen concentration
C. To cool the building
D. To test alarms
Correct Answer: A. To prevent oxidation inside the tubing
Rationale: An inert gas purge helps prevent internal oxide formation during brazing.
11. Which gas is commonly used as an inert purge gas during medical gas
brazing?
A. Oxygen
B. Nitrogen
C. Hydrogen
D. Nitrous oxide
Correct Answer: B. Nitrogen
Rationale: Nitrogen is commonly used to displace oxygen and reduce internal oxidation during
brazing.
12. Why should oxygen never be used as a brazing purge gas?
A. It can intensify combustion and create a serious fire hazard
B. It is too cold
C. It cannot flow through tubing
D. It prevents all brazing
Correct Answer: A. It can intensify combustion and create a serious fire hazard
Rationale: Oxygen supports combustion and should not be used as an inert purge gas.
