FCTC Test Verbal & Visual Comprehension Questions and Answers 2 — Questions and Answers
Question 1: A fire department apparatus diagram labels component A as the discharge manifold and component B as the intake manifold. Water is being pumped from a hydrant into the apparatus. Which manifold receives the water from the hydrant?
- Component A — the discharge manifold
- Component B — the intake manifold (Correct answer)
- Both manifolds simultaneously
- Neither — water goes directly to the hose lines without passing through a manifold
Correct answer: Component B — the intake manifold
The intake manifold receives water coming into the apparatus from the hydrant; the discharge manifold sends pressurized water out to the hose lines.
Pump anatomy uses consistent terminology: the intake manifold receives the incoming water supply from the hydrant, tender, or drafting source, and the discharge manifold distributes pressurized water to hose lines. Correctly identifying intake versus discharge components is essential for pump operations and troubleshooting.
Question 2: A diagram shows four building cross-sections labeled Type I through Type V. Type I shows concrete columns, Type II shows unprotected steel, Type III shows masonry exterior with wood interior, and Type V shows wood frame throughout. A fire burns for 20 minutes. Which type is MOST likely to still have intact structural members?
- Type V wood-frame construction
- Type III ordinary construction
- Type II non-combustible unprotected steel
- Type I fire-resistive protected concrete (Correct answer)
Correct answer: Type I fire-resistive protected concrete
Type I fire-resistive construction with protected concrete and steel maintains structural integrity far longer under fire exposure than any other construction type.
After 20 minutes of fire exposure, Type V wood framing may have failed completely, Type II unprotected steel may be softening and losing strength, Type III wood interior is likely failing, and Type I protected concrete and steel is rated to resist fire for 2 or more hours.
Question 3: A firefighter reads a map legend showing: filled blue circle equals hydrant, open blue square equals standpipe, red triangle equals fire department connection. The firefighter sees two filled blue circles and one red triangle on a pre-plan map. What does this indicate?
- Two standpipes and one hydrant
- Two hydrants and one fire department connection (Correct answer)
- Two FDCs and one hydrant
- One hydrant and two FDCs
Correct answer: Two hydrants and one fire department connection
Per the legend: filled blue circle equals hydrant (two of them) and red triangle equals FDC (one of them).
Pre-fire plan map reading requires precise application of legend definitions. Two filled blue circles equal 2 hydrants and one red triangle equals 1 FDC. Misreading map symbols can lead to incorrect resource positioning and critical delays during fire suppression operations.
Question 4: A photograph shows a firefighter's SCBA facepiece with condensation and fogging on the inside of the lens. What does this most likely indicate?
- The SCBA is operating correctly and condensation is normal under heavy breathing
- The facepiece seal may be compromised, allowing outside air and moisture to enter (Correct answer)
- The air cylinder pressure is too high and causing excess moisture
- The regulator is over-pressurizing the facepiece
Correct answer: The facepiece seal may be compromised, allowing outside air and moisture to enter
Internal facepiece fogging or condensation suggests ambient moisture is entering the mask, which may indicate a seal compromise that must be evaluated before IDLH entry.
A properly sealed positive-pressure SCBA facepiece should not show condensation from ambient air. Interior fogging indicates ambient moisture is entering through a seal failure caused by a damaged seal, facial hair, incorrect sizing, or improper donning. A compromised seal in an IDLH atmosphere allows toxic gases to enter.
Question 5: A training diagram shows a fire burning in the lower-left corner of a room. Arrows indicate smoke rising to the ceiling and banking down. The neutral plane is shown at mid-room height. Where should a firefighter crawl to remain below most of the toxic smoke?
- Above the neutral plane
- At the neutral plane level
- Below the neutral plane (Correct answer)
- In the center of the room at standing height
Correct answer: Below the neutral plane
The neutral plane separates the upper hot toxic smoke layer from the lower cooler air layer. Firefighters must stay below the neutral plane to reduce heat and toxin exposure.
In a compartment fire, hot gases and smoke rise and bank down from the ceiling. The neutral plane is the boundary between the upper hot and toxic smoke layer and the lower cooler air layer. Staying below this plane reduces heat exposure and CO and smoke inhalation, which is a fundamental firefighter survival technique.
Question 6: An equipment schematic shows a centrifugal pump with arrows indicating water flow entering from the left at the center of the impeller and exiting at the outer edge. What principle drives water from the center to the outer edge?
- Magnetic force from the motor housing
- Centrifugal force — the spinning impeller flings water outward from the center (Correct answer)
- Atmospheric pressure pushing water inward toward the center
- Gravity pulling water downward from the center hub
Correct answer: Centrifugal force — the spinning impeller flings water outward from the center
Centrifugal pumps use a spinning impeller to impart centrifugal force on water, flinging it outward from the center to the discharge outlet at higher velocity and pressure.
In a centrifugal pump, the rotating impeller imparts velocity or kinetic energy to water, flinging it outward by centrifugal force. The volute casing then converts velocity to pressure. Fire department centrifugal pumps can move thousands of GPM at high pressure and are the standard pump type for structural firefighting apparatus.
A fire department apparatus diagram labels component A as the discharge manifold and component B as the intake manifold.
Water is being pumped from a hydrant into the apparatus.
Which manifold receives the water from the hydrant?
