NFSI Information Ordering Application 3 — Questions and Answers
Question 1: A fire station receives four simultaneous alarms. Rule: respond to alarms in order of (1) confirmed structure fire, (2) gas leak with ignition risk, (3) vehicle accident with injuries, (4) trash fire. The calls are: Call A=gas leak, Call B=trash fire, Call C=structure fire, Call D=vehicle accident. Correct dispatch order:
- C, A, D, B (Correct answer)
- A, C, D, B
- C, D, A, B
- D, C, A, B
Correct answer: C, A, D, B
Structure fire (C) first, gas leak with ignition risk (A) second, vehicle accident (D) third, trash fire (B) last per the priority rule.
Question 2: A rescue protocol states: (E) extricate victim, (F) treat airway, (G) move victim to safe zone, (H) perform primary assessment. The rule requires H before F, F before E, and G only after E. Which is correct?
- H, F, E, G (Correct answer)
- F, H, E, G
- E, H, F, G
- H, E, F, G
Correct answer: H, F, E, G
Assessment (H) precedes treatment (F), which precedes extrication (E), and the victim moves to safety (G) only after extrication.
Question 3: A multi-unit response rule states Engine 1 stages at hydrant, Ladder 1 positions for aerial, Engine 2 enters the block last after both are set. Units arrive in order: Ladder 1, Engine 2, Engine 1. What is the correct positioning sequence?
- Engine 1, Ladder 1, Engine 2 (Correct answer)
- Ladder 1, Engine 1, Engine 2
- Engine 2, Engine 1, Ladder 1
- Engine 1, Engine 2, Ladder 1
Correct answer: Engine 1, Ladder 1, Engine 2
Engine 1 must secure the hydrant first regardless of arrival order, Ladder 1 positions for aerial second, and Engine 2 enters last.
Question 4: Post-fire overhaul rules state: (1) confirm fire is fully extinguished, (2) open walls and ceilings to check for extension, (3) remove smoldering debris, (4) apply water to hot spots. The rule states step 4 only follows step 3 if hot spots are found. No hot spots are found. Correct sequence:
- 1, 2, 3, 4
- 1, 4, 2, 3
- 1, 2, 3 (Correct answer)
- 2, 1, 3, 4
Correct answer: 1, 2, 3
Without hot spots, step 4 is skipped; the correct sequence is confirm extinguishment, open walls, then remove debris.
Question 5: An evacuation alarm procedure requires: (W) account for all personnel, (X) sound evacuation tone, (Y) withdraw all crews, (Z) establish rehab area. The rule states Y must immediately follow X with no other steps between them. Which ordering is valid?
- Z, X, W, Y
- X, Y, Z, W
- X, Z, Y, W
- Z, X, Y, W (Correct answer)
Correct answer: Z, X, Y, W
Rehab is set before evacuation tone, tone is sounded, crews withdraw immediately after, then accountability is taken.
Question 6: A ladder placement rule states: place the ladder so the tip is at or just above the windowsill, with a 75-degree climbing angle. Steps are: (A) foot ladder, (B) raise to height, (C) select placement spot, (D) adjust angle. Correct sequence:
- C, A, B, D (Correct answer)
- A, C, B, D
- B, C, A, D
- C, B, A, D
Correct answer: C, A, B, D
Select the placement spot first, foot the ladder, raise to the correct height, then adjust angle to 75 degrees.
Question 7: A company officer receives four tasks: (1) file incident report, (2) debrief crew, (3) return apparatus to service, (4) conduct equipment inspection. The rule: apparatus must be returned before filing the report, and inspection before returning apparatus. Correct order:
- 2, 4, 3, 1 (Correct answer)
- 4, 3, 1, 2
- 3, 4, 2, 1
