FIREFIGHTER 1 & 2 AND HAZMAT
OPERATIONS PRACTICE TEST #3
QUESTIONS & VERIFIED ANSWERS
2026/2027 UPDATE. A+ GRADE
1. During a structural fire, at what temperature does flashover typically occur as the thermal
layer reaches its peak?
A. 600°F to 800°F
B. 1800°F to 2000°F
C. 400°F to 500°F
D. 1100°F to 1200°F
Answer: D
Conceptual Explanation: Flashover occurs when all combustible surfaces in a
compartment are heated to their ignition temperature, typically around 1100°F (593°C).
2. A liquid with a specific gravity of 0.8 will behave in what manner when spilled into a body
of water?
A. It will sink to the bottom
,B. It will mix completely with the water
C. It will float on the surface
D. It will react violently and explode
Answer: C
Conceptual Explanation: Specific gravity is the ratio of the weight of a liquid to the weight
of water; water is 1.0, so 0.8 will float.
3. According to NFPA 1981, how often must a composite SCBA cylinder be hydrostatically
tested?
A. Every 5 years
B. Every 10 years
C. Every 3 years
D. Annually
Answer: A
Conceptual Explanation: Composite cylinders require hydrostatic testing every 5 years
and have a 15-year service life.
4. When placing a ladder for a window rescue, where should the tip of the ladder be
positioned?
A. Just below the windowsill
B. In the center of the window opening
, C. Three rungs above the roofline
D. At the top of the window frame
Answer: A
Conceptual Explanation: Placing the ladder tip just below the sill allows for easier access
and egress for victims and firefighters.
5. What is the flow capacity of a fire hydrant painted with a light blue bonnet according to
NFPA 291?
A. 1500 GPM or greater
B. 500–999 GPM
C. 1000–1499 GPM
D. Less than 500 GPM
Answer: A
Conceptual Explanation: Light Blue represents Class AA hydrants with a flow of 1500
GPM or greater.
6. In the Emergency Response Guidebook (ERG), which section provides the Initial Isolation
and Protective Action Distances for toxic materials?
A. Blue pages
B. Yellow pages
C. Green pages
