FIREFIGHTER 1 & 2 AND HAZMAT
OPERATIONS PRACTICE TEST #2
QUESTIONS & VERIFIED ANSWERS
2026/2027 UPDATE. A+ GRADE
1. Which stage of fire development occurs when all exposed combustible surfaces in an
enclosed space have been heated to their ignition temperature and ignite nearly
simultaneously?
A. Incipient stage
B. Flashover
C. Growth stage
D. Fully developed stage
Answer: B
Conceptual Explanation: Flashover is the transition between the growth and fully
developed stages, characterized by the simultaneous ignition of all combustible contents in
the room.
2. According to NFPA 1901, what is the minimum pump capacity for a vehicle to be classified
as a fire department pumper?
A. 500 gpm (1900 L/min)
,B. 750 gpm (2850 L/min)
C. 1000 gpm (3800 L/min)
D. 1250 gpm (4750 L/min)
Answer: B
Conceptual Explanation: NFPA 1901 specifies that a pumper must have a minimum pump
capacity of 750 gpm.
3. In the Incident Command System (ICS), which section is responsible for providing facilities,
services, and materials support for the incident?

extinguishing agent?
A. Class A
B. Class D
, C. Class B
D. Class K
Answer: B
Conceptual Explanation: Class D fires involve combustible metals and require specialized
dry powder agents.
5. What is the expansion ratio of most standard firefighting foams used for structural fires?
A. 2:1 to 5:1
B. 20:1 to 200:1
C. Low-expansion foam, typically up to 20:1
D. 200:1 to 1000:1
Answer: C
Conceptual Explanation: Low-expansion foam has an expansion ratio of up to 20:1 and is
the primary type used for structural and hydrocarbon fires.
6. Which type of building construction is known as ‘Noncombustible or Limited Combustible’?
A. Type II
B. Type I
C. Type III
D. Type IV
