FCTC Test Technical Reading and Recall Questions and Answers 2 — Questions and Answers
Question 1: According to NFPA 1981, what is the minimum rated service duration required for a firefighter's SCBA used in IDLH conditions?
- 15 minutes
- 30 minutes (Correct answer)
- 45 minutes
- 60 minutes
Correct answer: 30 minutes
NFPA 1981 requires a minimum 30-minute rated service time for SCBA used in IDLH atmospheres during structural firefighting.
NFPA 1981 requires SCBA to provide at least 30 minutes of rated service time for structural firefighting. Most departments use 30 or 45-minute cylinders. Actual duration depends heavily on work rate since a firefighter working at maximum exertion can exhaust a 30-minute cylinder in 15 to 20 minutes.
Question 2: A technical bulletin states: 'The maximum load on a single roof ladder hook shall not exceed the ladder rated load.' A 24-foot roof ladder is rated for 250 lbs. Two firefighters each weighing 200 lbs with gear attempt to use the ladder simultaneously. What does the bulletin require?
- Both firefighters may use the ladder since 200 lbs each is under the 250 lb rating
- Only one firefighter may be on the ladder at a time to remain within the 250-lb rating (Correct answer)
- The ladder must be replaced with a higher-rated model
- Both firefighters may use the ladder with a spotter present
Correct answer: Only one firefighter may be on the ladder at a time to remain within the 250-lb rating
The bulletin limits total load to the rated capacity. Each firefighter weighs 200 lbs with gear, so combined weight of 400 lbs exceeds the 250-lb rating. Only one at a time is permitted.
Two firefighters at 200 lbs each equals 400 lbs total, exceeding the 250-lb rating. The technical bulletin requires that the load not exceed 250 lbs at any time, so only one firefighter may use the ladder at a time. Exceeding rated ladder loads causes structural failure and is a significant cause of firefighter falls.
Question 3: A firefighting manual states: 'The five building construction types (Types I through V) are classified by the fire resistance of structural components, not by material alone.' Type I is most fire-resistive and Type V is least. Which type would maintain structural integrity longest in a fire?
- Type V wood-frame construction
- Type III ordinary construction
- Type II non-combustible construction
- Type I fire-resistive construction (Correct answer)
Correct answer: Type I fire-resistive construction
Type I construction uses fire-resistive rated structural members (protected steel and reinforced concrete) that maintain structural integrity under fire conditions for the longest period.
Type I (Fire-Resistive) construction uses protected steel or reinforced concrete rated to resist fire exposure for 2 to 4 hours. Type V uses unprotected combustible wood framing that can fail in minutes. Understanding construction types allows firefighters to estimate how long a structure will remain tenable.
Question 4: A hose specification sheet states: 'Service test pressure for 2.5-inch attack hose is 300 psi.' A pump operator charges the line to 250 psi during a fire. Is the hose being operated within safe parameters?
- No — service test pressure is the maximum allowable operating pressure
- Yes — 250 psi is below the 300 psi service test pressure (Correct answer)
- No — 2.5-inch hose cannot be used above 200 psi
- The service test pressure does not apply during actual fire operations
Correct answer: Yes — 250 psi is below the 300 psi service test pressure
Service test pressure (300 psi) is a periodic proof-test pressure, not the maximum operating pressure. Operating at 250 psi is within normal safe limits.
Service test pressure verifies hose integrity at periodic intervals per NFPA 1962. Operating pressure is typically well below service test pressure. 250 psi is within normal operating range for 2.5-inch attack hose and is below the service test pressure of 300 psi.
Question 5: A TIC user guide states: 'TIC displays relative temperature differences. A completely dark image indicates all objects are at uniform temperature, NOT that the area is cool or safe.' A firefighter scans a smoke-filled room and sees a uniform dark TIC image. What should they conclude?
- The room is at ambient temperature and safe to enter
- The TIC camera is too dark to function in this room
- All surfaces are at the same temperature — the absence of differential may mean fire is not present
- Uniform temperature does not confirm safety and additional verification is required before concluding anything (Correct answer)
Correct answer: Uniform temperature does not confirm safety and additional verification is required before concluding anything
The user guide warns that a dark TIC image means uniform temperature, not a cool room. Additional verification is required before drawing any conclusion about safety.
TICs show temperature differentials. If all surfaces have reached the same potentially very high temperature, the image appears uniformly dark. This may mean a compartment has already flashed over and is uniformly hot throughout. Never rely solely on TIC for safety decisions.
Question 6: An ICS organization chart states: 'The span of control should be between 3 and 7 subordinates per supervisor, with 5 being optimal.' A sector officer is managing 9 units. What should occur according to the chart?
- Nothing — 9 units is within the acceptable range
- The sector should be split or another supervisory level added to restore proper span of control (Correct answer)
- All 9 units should operate without any sector officer oversight
- The sector officer should delegate all authority to a single unit leader
Correct answer: The sector should be split or another supervisory level added to restore proper span of control
9 subordinates exceeds the ICS maximum span of control of 7 — the sector should be divided or an additional supervisory level should be inserted.
ICS span of control (3 to 7, optimal 5) ensures supervisors can effectively monitor and communicate with their subordinates. At 9 units, the sector officer is overloaded. ICS doctrine requires splitting the sector or adding a branch or division level to bring each supervisor within the 3 to 7 range.
