FCTC Verbal & Visual Comprehension 3 — Questions and Answers
Question 1: A passage states: 'Upon arrival, the incident commander conducted a 360-degree size-up.' What is the primary purpose of a 360-degree size-up?
- To gather comprehensive visual information about all sides of the incident (Correct answer)
- To rotate the command post location during the incident
- To assign sectors to four different companies
- To document the incident on a circular diagram
Correct answer: To gather comprehensive visual information about all sides of the incident
A 360-degree size-up means walking completely around the structure to observe conditions on all sides before committing resources.
Question 2: A paragraph reads: 'Class A fires involve ordinary combustibles such as wood, paper, and cloth. Class B fires involve flammable liquids and gases.' A firefighter encounters a burning pile of wooden pallets. Which class does this fire belong to?
- Class A (Correct answer)
- Class B
- Class C
- Class D
Correct answer: Class A
Wood is listed as an ordinary combustible, which is the definition of a Class A fire.
Question 3: An aerial photograph of an incident scene shows multiple hose lines running from the street into a building entrance. One hose line branches at a wye fitting. How many separate hose streams does the wye fitting create from that single line?
- Two (Correct answer)
- Three
- Four
- One — it only extends the line
Correct answer: Two
A wye fitting splits one hose line into two separate outlet lines.
Question 4: A training manual states: 'When reading a fire behavior diagram, arrows pointing upward along a wall indicate convective heat transfer.' In the diagram, you see arrows traveling upward along the wall toward the ceiling. What process is being illustrated?
- Convection (Correct answer)
- Conduction
- Radiation
- Pyrolysis
Correct answer: Convection
Upward-moving arrows along a wall in a fire behavior diagram represent convective heat transfer as described in the passage.
Question 5: The following sentence appears in a department SOP: 'Personnel shall maintain radio communication with command at intervals not to exceed five minutes during interior operations.' A crew enters at 09:00. By what time must they make their first radio check?
- 09:05 (Correct answer)
- 09:10
- 09:15
- 09:30
Correct answer: 09:05
The SOP requires contact within five minutes, so from 09:00 the first check must happen no later than 09:05.
Question 6: A hazard symbol shows a skull and crossbones inside a diamond. Which hazard class does this symbol primarily communicate?
- Toxic or poisonous material (Correct answer)
- Flammable material
- Explosive material
- Radioactive material
Correct answer: Toxic or poisonous material
The skull and crossbones symbol is universally used to indicate toxic or poisonous hazards.
Question 7: A passage describes: 'Thermal imaging cameras display heat signatures where lighter colors represent higher temperatures.' On a TIC image you see a dark gray door frame with a bright white glow at the base of the door. What does this indicate?
- Intense heat accumulating at the base of the door, indicating fire on the other side (Correct answer)
- Cold air is entering under the door from outside
- The door itself is made of a heat-reflective material
- The floor is wet, causing a temperature anomaly
Correct answer: Intense heat accumulating at the base of the door, indicating fire on the other side
A bright white glow at the door's base on a TIC means high heat is present there, strongly suggesting an active fire on the other side.
