NFSI Information Ordering Application 4 — Questions and Answers
Question 1: A wildland fire triage rule ranks suppression priorities: (1) structures with people inside, (2) unoccupied structures in immediate flame path, (3) natural resources, (4) roads and infrastructure. A crew faces: burning timber (T), evacuated cabin (C), occupied farmhouse (F), access road (R). Correct priority order:
- F, C, T, R (Correct answer)
- C, F, T, R
- F, T, C, R
- R, F, C, T
Correct answer: F, C, T, R
Occupied farmhouse is priority 1, evacuated cabin priority 2, timber (natural resources) priority 3, and road last.
Question 2: A water supply rule for rural fires states: (I) establish a tanker shuttle, (II) calculate flow demand, (III) identify the nearest water source, (IV) assign fill site and dump site. The rule says III must precede IV, and II must precede I. Which order satisfies both rules?
- II, III, IV, I (Correct answer)
- III, II, IV, I
- II, IV, III, I
- I, III, II, IV
Correct answer: II, III, IV, I
Calculate flow demand first, then locate the water source, assign fill/dump sites, then establish the shuttle.
Question 3: A confined space rescue protocol requires: (A) test atmosphere, (B) lower retrieval line, (C) post attendant at entry, (D) don rescue harness. The rule states A and C must both be completed before B or D begin. Which is a valid sequence?
- A, D, C, B
- C, A, D, B (Correct answer)
- B, A, C, D
- D, C, A, B
Correct answer: C, A, D, B
Both atmosphere testing (A) and posting an attendant (C) must finish before lowering a line or donning harness; C then A satisfies this.
Question 4: A ventilation decision tree states: if the fire is in a basement, ventilate horizontally before vertically. Steps: (P) open windows on opposite side of fire, (Q) open roof hatch, (R) confirm basement fire location, (S) open windows on fire side. Correct sequence for a confirmed basement fire:
- R, P, S, Q (Correct answer)
- R, S, P, Q
- Q, R, P, S
- R, Q, P, S
Correct answer: R, P, S, Q
Confirm location, open opposite-side windows first (horizontal ventilation), then fire-side windows, then roof hatch if needed.
Question 5: An EMS-assist protocol for firefighters states: (1) ensure scene safety, (2) perform CPR if no pulse, (3) apply AED, (4) contact medical direction. The rule: step 4 is required before step 3 only if patient is under 8 years old. Patient is 45 years old. Correct sequence:
- 1, 2, 3, 4 (Correct answer)
- 1, 4, 2, 3
- 4, 1, 2, 3
- 1, 2, 4, 3
Correct answer: 1, 2, 3, 4
For an adult patient, medical direction contact before AED use is not required; the standard sequence applies.
Question 6: A post-incident accountability rule requires: (α) verify all personnel accounted for, (β) release mutual aid units, (γ) transfer command to investigation team, (δ) notify dispatch of incident termination. The rule: α must precede β and γ; δ is last. Valid sequence:
- α, γ, β, δ
- β, α, γ, δ
- γ, β, α, δ
- α, β, γ, δ (Correct answer)
Correct answer: α, β, γ, δ
Account for all personnel first, then release mutual aid, then transfer command, then notify dispatch to terminate.
Question 7: A high-rise fire protocol orders elevator, stairwell, and lobby control as: (1) lock out elevators two floors below fire, (2) post stairwell control at fire floor minus one, (3) establish lobby control, (4) identify fire floor via annunciator panel. Correct sequence:
- 4, 3, 1, 2 (Correct answer)
- 3, 4, 1, 2
- 1, 2, 3, 4
- 4, 1, 3, 2
Correct answer: 4, 3, 1, 2
Identify the fire floor first, then establish lobby control, lock elevators, then post stairwell control at the correct floor.
