Rationales
Exam Coverage Overview (10 Key Points)
1. Exam Structure & Licensing – Administered by Massachusetts Department of Fire
Services; 100 questions, 2-hour time limit, open-book with approved references. First
Class license is for high-pressure boilers > 15 psig .
2. Boiler Types & Classifications – Fire-tube vs. water-tube boilers, cast iron boilers,
electric boilers, and classification by pressure and application .
3. ASME Boiler & Pressure Vessel Code – Section I (Power Boilers), Section IV (Low-
Pressure Heating), Section VI (Care and Operation), Section VII (Power Boiler Care),
Section VIII (Pressure Vessels), Section IX (Welding) .
4. Boiler Operation & Startup – Proper startup sequences, warm-up procedures, water
level management, and preventing thermal shock .
5. Safety Devices & Controls – Safety valves (spring-loaded pop-type), low-water cutoffs
(tested weekly), pressure gauges, water level gauges, pressuretrols, and aquastats .
6. Water Treatment & Chemistry – pH control (8.5-9.5), dissolved oxygen management
(sodium sulfite/hydrazine), scale prevention, corrosion control, blowdown procedures .
7. Combustion & Fuel Systems – Fuel/air ratios (optimal O₂ 1-2%), burner operation,
combustion efficiency, soot buildup, stack temperature analysis .
8. Boiler Efficiency & Calculations – Boiler horsepower (34.5 lb/hr), heat transfer
calculations, efficiency formulas, and fuel consumption analysis .
9. Inspection, Testing & Maintenance – Hydrostatic testing (1.5 × MAWP), safety valve
testing (monthly), low-water cutoff testing (weekly), NBIC repair/alteration forms .
10. Massachusetts Regulations & Safety – 527 CMR 1.00 regulations, OSHA requirements,
confined space safety, and Massachusetts-specific requirements .

1. What is the primary agency responsible for issuing Fireman licenses in Massachusetts?
A) Massachusetts Department of Labor
B) Massachusetts Department of Fire Services
C) Massachusetts Board of Boiler Rules
D) Massachusetts Department of Public Safety
Correct Answer: B
Rationale: The Massachusetts Department of Fire Services, through its Boiler Inspection Unit, is
responsible for issuing Fireman licenses (First, Second, and Third Class) in Massachusetts. The
Board of Boiler Rules establishes regulations under 527 CMR 1.00 .
2. A First Class Fireman license in Massachusetts is required to operate boilers with a
maximum allowable working pressure (MAWP) of:
A) 0-15 psig
B) 15-100 psig
C) Over 100 psig
D) Over 15 psig
Correct Answer: D
Rationale: A First Class Fireman license is required for boilers operating at pressures exceeding
15 psig. This includes high-pressure steam boilers and high-temperature hot water boilers .

3. What is the minimum age requirement for a Massachusetts First Class Fireman license?
A) 18 years old
B) 21 years old
C) 25 years old
D) 30 years old
Correct Answer: B
Rationale: The minimum age requirement for a Massachusetts First Class Fireman license is 21
years old. This is consistent with requirements for high-pressure boiler operator licensing .
4. What is the experience requirement for a Massachusetts First Class Fireman license?
A) 1 year of experience on high-pressure boilers
B) 2 years of experience on high-pressure boilers
C) 3 years of experience on high-pressure boilers
D) 5 years of experience on high-pressure boilers
Correct Answer: C
Rationale: Massachusetts requires 3 years of experience on high-pressure boilers for a First
Class Fireman license. This experience must be documented and verified by previous employers
.

5. What is the maximum allowable working pressure (MAWP) for a low-pressure steam
boiler?
A) 10 psig
B) 15 psig
C) 30 psig
D) 50 psig
Correct Answer: B
Rationale: Low-pressure steam boilers are defined as those operating at ≤15 psig. This is a
fundamental distinction in boiler licensing and code requirements .
6. What is the maximum allowable working pressure (MAWP) for a low-pressure hot water
boiler?
A) 100 psig at 200°F
B) 125 psig at 225°F
C) 160 psig at 250°F
D) 200 psig at 300°F
Correct Answer: C
Rationale: The maximum pressure and temperature for a low-pressure hot water system is
typically 160 psig at 250°F per ASME Section IV .
