WGU C468 – Information Management and Application of
Technology (Latest 2024/2025) | Complete Solution
Question 1:
Which stage of fire development is characterized by the transition from growth to full room
involvement?
A) Ignition stage
B) Growth stage
C) Flashover
D) Decay stage
Correct Answer: C
Rationale: Flashover (C) occurs when all combustible materials in a room ignite nearly
simultaneously due to heat buildup, transitioning from growth to fully developed (NFPA 1001).
Ignition (A) is initial spark. Growth (B) precedes flashover. Decay (D) follows fuel/oxygen
depletion.
Question 2:
What is the primary purpose of ventilation during fire suppression per NFPA 1001?
A) To cool the fire
B) To improve visibility and reduce heat for firefighters
C) To supply oxygen to the fire
D) To create a draft for extinguishment
Correct Answer: B
Rationale: Ventilation (B) removes smoke/heat to enhance firefighter safety and visibility,
coordinated with suppression (NFPA 1001). Cooling (A) is secondary. Oxygen (C) feeds fire.
Draft (D) risks intensification.
Question 3:
Scenario: A firefighter locates a victim during a primary search in a smoke-filled room. What is
the first action?
A) Remove the victim immediately
B) Call for backup
C) Assess airway and breathing
D) Mark location and continue
Correct Answer: C
Rationale: Airway/breathing assessment (C) prioritizes life-threatening conditions before
extraction (NFPA 1001, PHTLS). Immediate removal (A) risks injury. Backup (B) secondary.
Marking (D) delays care.
Question 4:
What is the required hydrostatic testing interval for SCBA cylinders per NFPA 1981?
,A) 3 years
B) 5 years
C) 10 years
D) 15 years
Correct Answer: B
Rationale: NFPA 1981 mandates testing every 5 years (B) for SCBA cylinder integrity. 3 (A) for
low-pressure. 10/15 (C, D) too long.
Question 5:
During HAZMAT awareness, a spill with a strong odor and blue smoke suggests:
A) Flammable liquid
B) Oxidizer
C) Corrosive acid
D) Poisonous gas
Correct Answer: B
Rationale: Blue smoke (B) indicates oxidizer per ERG guide 140. Flammable (A) yellow/orange
flames. Corrosive (C) white fumes. Gas (D) often colorless.
Question 6:
Under ICS (NFPA 1561), the safety officer’s primary role is:
A) Resource allocation
B) Hazard identification and mitigation
C) Incident command
D) Public information
Correct Answer: B
Rationale: Safety officer (B) monitors hazards and advises IC (NFPA 1561). Resources (A)
logistics. Command (C) IC. Information (D) PIO.
Question 7:
When using a chainsaw for ventilation, a firefighter must:
A) Start in hot zone
B) Use a guide bar with safety chain
C) Operate without PPE
D) Use high speed only
Correct Answer: B
Rationale: Safety chain (B) reduces kickback (NFPA 1001). Start in safe zone (A) false. PPE
required (C) false. Speed varies (D).
Question 8:
Type I building construction is defined as:
A) Fire-resistive
B) Wood-framed
,C) Heavy timber
D) Ordinary

Wood (B) Type V. Timber (C) Type IV. Ordinary (D) Type III.
Question 9:
In EMS, the primary survey for a trauma patient starts with:
A) Scene safety and airway
B) History taking
C) Vital signs
D) Secondary assessment
Correct Answer: A
Rationale: Scene safety/airway (A) is first per PHTLS/EMT protocols. History (B) secondary.
Vitals (C) after ABCs. Secondary (D) later.
Question 10:
Fire prevention inspections prioritize:
A) Life safety code compliance
B) Electrical only
C) Appliances
D) No inspections
Correct Answer: A
Rationale: NFPA 1730/IFC requires life safety compliance (A). Electrical (B), appliances (C)
partial. Inspections required (D).
Question 11:
The fire tetrahedron includes all except:
A) Fuel
B) Oxygen
C) Heat
D) Water
Correct Answer: D
Rationale: Tetrahedron: fuel, oxygen, heat, chain reaction (A-C). Water (D) extinguishes.
Question 12:
For a Class K fire (cooking oil), the appropriate extinguisher is:
A) Wet chemical
B) Water
C) CO2
D) Dry chemical
, Correct Answer: A
Rationale: Wet chemical (A) saponifies oils (NFPA 10). Water (B) splatters. CO2 (C) ineffective.
Dry (D) for B fires.
Question 13:
Scenario: A firefighter observes puffing smoke from a door, indicating a backdraft. The
immediate action is:
A) Open the door fully
B) Evacuate and close door
C) Spray water inside
D) Ventilate immediately
Correct Answer: B
Rationale: Closing door (B) contains backdraft, then ventilate from outside (NFPA 1001).
Opening (A) triggers explosion. Water (C) steam risk. Vent (D) premature.
Question 14:
SCBA low-air alarm activates at:
A) 25% capacity
B) 50%
C) 10%
D) 75%
Correct Answer: A
Rationale: NFPA 1981 sets alarm at 25% (A) for safe egress.
Question 15:
HAZMAT operations-level response includes:
A) Defensive actions like diking
B) Hot zone entry
C) Victim rescue inside
D) No action
Correct Answer: A
Rationale: Operations (A) dike/divert without entry (NFPA 1072). Entry (B), rescue (C)
technician-level. Awareness (D) recognize only.
Question 16:
In ICS, the ideal span of control is:
A) 3-7 subordinates
B) 1-2
C) 10-12
D) Unlimited
Correct Answer: A
Rationale: NIMS recommends 3-7 (A) for manageable oversight.
