NFSI Information Ordering Application 5 — Questions and Answers
Question 1: A hazmat response rule ranks decontamination corridor setup: (I) establish cold zone boundary, (II) position decon stations within warm zone, (III) identify hot zone perimeter, (IV) brief decon team. The rule: III before I, and I before II. Which is valid?
- III, I, IV, II (Correct answer)
- I, III, II, IV
- III, IV, I, II
- IV, III, I, II
Correct answer: III, I, IV, II
Hot zone identified first, cold zone boundary set, team briefed, then decon stations positioned within the warm zone.
Question 2: A building search rule for a smoke-filled floor requires: (A) orient at doorway before entering, (B) search in a systematic wall-following pattern, (C) communicate clear or victim found to IC, (D) stay low below smoke layer. Which order is correct?
- A, D, B, C (Correct answer)
- D, A, B, C
- B, A, D, C
- A, B, D, C
Correct answer: A, D, B, C
Orient at the doorway first, then stay low, use a systematic search pattern, and report findings to IC when complete.
Question 3: A fire investigation scene preservation rule states: (1) photograph scene before anything is moved, (2) identify point of origin, (3) collect evidence samples, (4) allow salvage operations. The rule: step 4 only after steps 1, 2, and 3 are complete. An investigator skips step 2 and goes to 3. What is wrong?
- Step 3 cannot occur before step 1
- Salvage operations were started too early
- Point of origin must be identified before evidence is collected (Correct answer)
- Photography must follow evidence collection
Correct answer: Point of origin must be identified before evidence is collected
The protocol requires point-of-origin identification before collecting samples so that evidence context is preserved.
Question 4: A hose load deployment drill specifies four actions: (W) pull the load from the bed, (X) advance toward the fire, (Y) bleed air and open nozzle, (Z) connect to discharge outlet. The rule: Z before W, W before X, Y is last. Correct order:
- W, Z, X, Y
- Z, W, X, Y (Correct answer)
- X, Z, W, Y
- Z, X, W, Y
Correct answer: Z, W, X, Y
Connect to discharge outlet first, pull the load, advance to the fire, then bleed air and open the nozzle.
Question 5: A night shift turnover protocol requires: (α) review open incidents log, (β) inspect apparatus and equipment, (γ) brief incoming crew, (δ) sign apparatus check sheet. The rule: β must precede δ; α must precede γ; δ and γ can happen in either order after their prerequisites. Which is NOT a valid sequence?
- α, β, γ, δ
- β, α, δ, γ
- α, β, δ, γ
- γ, α, β, δ (Correct answer)
Correct answer: γ, α, β, δ
Starting with γ (brief incoming crew) violates the rule that α (review open incidents) must precede γ.
Question 6: A foam application rule for flammable liquid fires states: (1) apply foam gently to avoid splashing fuel, (2) build a foam blanket from the near edge, (3) allow blanket to flow across surface, (4) do not direct stream directly into burning liquid. Which statement correctly applies this rule to a scenario where a firefighter streams foam directly into the center of the tank?
- This satisfies rule 2 by covering the center first
- This violates rule 4 and risks fuel splash that breaks the blanket (Correct answer)
- This violates rule 1 only; direction of stream does not matter
- This is acceptable if the foam expansion ratio is high enough
Correct answer: This violates rule 4 and risks fuel splash that breaks the blanket
Directing foam into burning liquid violates rule 4 and creates splash that disrupts the blanket, worsening the fire.
Question 7: A mayday rescue protocol assigns roles in this sequence: (1) IC designates Rapid Intervention Team leader, (2) RIT leader briefs team on downed firefighter's last known location, (3) RIT activates and enters structure, (4) IC broadcasts mayday acknowledgment to all units. The rule: step 4 must occur before step 1. A new IC broadcasts acknowledgment after designating the RIT leader. What error occurred?
- The RIT entered without a briefing
- IC acknowledged the mayday out of sequence after designating the RIT leader (Correct answer)
- The RIT leader briefed before IC acknowledged
- No error occurred; order is flexible
Correct answer: IC acknowledged the mayday out of sequence after designating the RIT leader
Per the protocol, IC must broadcast mayday acknowledgment before designating the RIT leader, so doing it after violates the sequence.
