SECTION ONE: QUESTIONS 1–100
Question 1
What is the primary function of a low-water fuel cutoff device on a steam boiler?
A. To relieve excessive pressure in the boiler
B. To prevent too high a water level
C. To shut off the burner in the event of a low water condition
,D. To measure the boiler water temperature
🟢 C. To shut off the burner in the event of a low water condition
🔴 RATIONALE: The low-water fuel cutoff is a critical safety device that automatically
shuts off fuel supply when water level drops below a safe threshold, preventing
overheating of heating surfaces and potential boiler failure [web:20][web:23].
Question 2
Which ASME section governs the construction of power boilers?
A. ASME Section IV
B. ASME Section I
C. ASME Section VIII
D. ASME Section IX
🟢 B. ASME Section I
🔴 RATIONALE: ASME Section I contains the rules for the construction of power boilers,
including thickness and pressure calculations, safety valve requirements, and inspection
standards [web:1][web:11].
Question 3
What does MAWP stand for in boiler terminology?
, A. Maximum allowable water pressure
B. Maximum allowable working pressure
C. Minimum allowable working pressure
D. Maximum operating water pressure
🟢 B. Maximum allowable working pressure
🔴 RATIONALE: MAWP is the highest pressure permitted under the design code (CSA B51 or
ASME), specified by the manufacturer to ensure safe boiler operation [web:19][web:25].
Question 4
A fusible plug is primarily installed in a boiler to:
A. Improve combustion efficiency
B. Prevent scale formation
C. Protect against low water conditions
D. Measure boiler temperature
🟢 C. Protect against low water conditions
🔴 RATIONALE: Fusible plugs contain a metal core that melts when overheated due to low
water conditions, providing a warning signal and preventing catastrophic boiler failure
[web:19].
