TCFP FIREFIGHTER I & II
COMPREHENSIVE EXAM PREP 2026
QUESTIONS AND ANSWERS
1. Which phenomenon is characterized by the spontaneous ignition of hot gas layers
accumulated at the ceiling level, often serving as a precursor to flashover?
A. Backdraft
B. Flameover
C. Rollover
D. Smoke Explosion
Answer: C
Conceptual Explanation: Rollover (or flameover) occurs when the unburned fire gases
accumulated at the top of a compartment ignite and flames propagate through the hot gas
layer or across the ceiling.
2. In accordance with NFPA 1901, what is the minimum pump capacity required for an
apparatus to be classified as a ‘pumper’?
A. 500 gpm
B. 750 gpm
,C. 1000 gpm
D. 1250 gpm
Answer: B
Conceptual Explanation: NFPA 1901 specifies that a pumper must have a permanently
mounted fire pump with a minimum capacity of 750 gpm.
3. When calculating friction loss in a fire hose, which factor has the most significant impact on
the resulting pressure drop?
A. Hose length
B. Hose diameter
C. Flow rate (Gallons per minute)
D. Coefficient of friction
Answer: C
Conceptual Explanation: Friction loss varies with the square of the flow rate (Q^2).
Doubling the flow quadruples the friction loss, making it the most influential variable.
4. Which type of building construction features load-bearing walls, floors, and roofs made of
noncombustible or limited-combustible materials, but lacks the fire-resistive ratings of Type
I?
A. Type IV
B. Type III
, C. Type II
D. Type V
Answer: C
Conceptual Explanation: Type II (Noncombustible) construction materials do not
contribute to fire spread but do not meet the stricter fire-resistive requirements of Type I.
5. What is the expansion ratio of most standard low-expansion firefighting foams?
A. 2:1 to 10:1
B. 20:1 to 200:1
C. 200:1 to 1000:1
D. 1000:1 to 2000:1
Answer: A
Conceptual Explanation: Low-expansion foam has an expansion ratio up to 20:1, though
2:1 to 10:1 is the common operational range for most nozzles.
6. Under the ICS system, which section is responsible for providing facilities, services, and
material support for the incident?
A. Operations
B. Planning
C. Logistics
