Exam Questions
Domain 1: Firefighter Safety, Health, and Wellness (10 questions)
1. You are the second-due engine at a working residential fire. As you advance the
attack line through the front door, your PASS device begins to sound. You are not in
distress and are moving with the line. What is your first action?
A. Immediately transmit a mayday over the radio
B. Stop moving for 30 seconds to allow the PASS to reset automatically
C. Check that the PASS is not false-alarming, reset it if necessary, and notify your officer
D. Remove your SCBA facepiece to hear radio traffic more clearly
Correct answer: C
,Rationale: A sounding PASS requires immediate investigation. If the firefighter is not in
distress, the device should be reset and the officer notified to prevent confusion on the
fireground. Option A is incorrect because a mayday is reserved for actual emergencies,
not a potentially false alarm. Option B is dangerous because stopping movement in a
hazardous environment without communicating status creates uncertainty. Option D is
a critical safety violation that exposes the firefighter to toxic products of combustion.
2. During rehab operations at a commercial building fire, a firefighter reports dizziness,
nausea, and a pounding headache. His skin is flushed and dry. The ambient temperature
is 95°F. What is the most likely condition, and what is the priority intervention?
A. Hypothermia; wrap the firefighter in blankets and apply heat packs
B. Heat stroke; initiate rapid cooling with ice packs to the neck, armpits, and groin, and
call for EMS
C. Carbon monoxide poisoning; administer 100% oxygen via NRB and monitor SpO2
D. Dehydration; have the firefighter drink water and return to the line
Correct answer: B
Rationale: Flushed, dry skin, dizziness, nausea, and headache in high heat indicate heat
stroke—a medical emergency requiring rapid cooling and EMS activation. Option A is
incorrect because hypothermia presents with cold, clammy skin. Option C is possible
but less likely given the dry, flushed skin and environmental conditions; CO poisoning
typically does not cause dry, flushed skin. Option D is insufficient because heat stroke
requires aggressive cooling beyond oral hydration, and returning to the line is
dangerous.
,3. You are donning your structural firefighting PPE for a reported structure fire. Your
officer notices you have not pulled your hood over your ears and that your coat collar is
exposed. Why is this a critical error?
A. It reduces the thermal protection rating of the coat by 50%
B. It creates a gap in the protective envelope, exposing skin to thermal injury and
products of combustion
C. It violates NFPA 1971 standards for coat length only
D. It prevents the SCBA facepiece from sealing properly
Correct answer: B
Rationale: The hood, coat, and SCBA facepiece must overlap to create a continuous
protective envelope. Exposed skin at the neck and ears is vulnerable to steam burns and
toxic gases. Option A overstates the thermal rating reduction. Option C is too narrow
because the issue is not coat length but the interface gap. Option D is incorrect because
the facepiece seal is against the face, not the hood.
4. At a motor vehicle accident on an interstate, you are directed to block traffic with the
engine. Where should the apparatus be positioned to provide the greatest protection for
the rescue crew working on the shoulder?
A. Park the engine 50 feet past the incident on the shoulder, angled away from traffic
B. Park the engine at an angle across the travel lane immediately upstream of the
incident, creating a physical barrier
C. Park the engine directly behind the damaged vehicle, facing oncoming traffic
D. Park the engine 200 feet past the incident and walk back to the scene
, Correct answer: B
Rationale: Angling the apparatus across the upstream travel lane creates a physical
barrier that absorbs impact from distracted or impaired drivers, protecting the rescue
work zone. Option A places the engine past the incident where it does not block
approaching traffic. Option C leaves the engine vulnerable to rear-end collision and does
not block the lane. Option D creates an excessive walk-back distance and offers no
immediate protection.
5. You are inside a commercial structure performing overhaul when a partial ceiling
collapse occurs, trapping your legs under debris. You can still breathe and your radio is
functional. What is the correct mayday transmission sequence?
A. "Mayday, mayday, mayday. Firefighter Smith, Engine 3, second floor, trapped by
collapse, legs pinned, air at 50%."
B. "Engine 3 to command, I need help, I'm stuck under some stuff on the second floor."
C. "Command, this is Smith, mayday, I'm trapped and need a RIC team right now."
D. "Mayday, mayday, mayday. Engine 3 has a man down on the second floor."
Correct answer: A
Rationale: A proper mayday follows the LUNAR protocol (Location, Unit, Name,
Assignment, Resources needed) and begins with three "mayday" calls to clear the radio
channel. Option B lacks the critical "mayday" prefix and is too vague. Option C is
incomplete because it omits location specifics and air status. Option D fails to identify
the trapped firefighter by name and does not specify the nature of the emergency or air
status.
