ESSENTIALS OF FIRE FIGHTING FINAL
EXAM 2026/2027 QUESTIONS AND
ANSWERS
1. What is the term for the chemical decomposition of a solid fuel through the action of heat?
A. Pyrolysis
B. Combustion
C. Fusion
D. Vaporization
Answer: A
Conceptual Explanation: Pyrolysis is the chemical decomposition of a solid material by
heating, which precedes combustion in solid fuels.
2. The heat transfer method that travels through space as an electromagnetic wave is known
as:
A. Direct Flame Contact
B. Convection
C. Conduction
,D. Radiation
Answer: D
Conceptual Explanation: Radiation is the transfer of heat energy by electromagnetic
waves, which can travel through a vacuum or air.
3. Which building construction type is characterized by the use of large-dimension lumber
(Heavy Timber)?
A. Type I
B. Type II
C. Type IV
D. Type V
Answer: C
Conceptual Explanation: Type IV construction, or Heavy Timber, uses large-dimension
lumber for structural members and lacks concealed spaces.
4. A fire that has consumed all available oxygen and is pulsing with yellowish-gray smoke may
undergo:
A. Backdraft
B. Flameover
C. Rollover
D. Flashover
, Answer: A
Conceptual Explanation: A backdraft is an explosive ignition of fire gases when oxygen is
introduced into a ventilation-limited compartment.
5. What is the minimum Thermal Protective Performance (TPP) rating required for structural
firefighting coats?
A. 40
B. 35
C. 20
D. 50
Answer: B
Conceptual Explanation: NFPA standards require a minimum TPP rating of 35 for
firefighting turnout gear, representing the time until a second-degree burn occurs.
6. At what percentage of cylinder capacity is the End-of-Service Time Indicator (EOSTI) alarm
on an SCBA required to trigger?
A. 33%
B. 25%
C. 50%
D. 10%
Answer: A
