NEWEST CERTIFIED FIRE PROTECTION
SPECIALIST (CFPS) CERTIFICATION EXAM
OFFERED BY NATIONAL FIRE PROTECTION
ASSOCIATION | COMPLETE EXAM Q&A WITH
RATIONALES
1. A building's egress system fails to meet the
required occupant flow rate. Which element is most
likely the bottleneck?
A) Exit stair width
B) Door opening force
C) Travel distance to the exit
D) Illumination of the exit sign
Correct answer: A
Rationale: Exit stair width directly limits the number
of people who can pass per minute; NFPA 101 sets
capacity based on width.
2. A warehouse stores Class III commodities with an
18‑foot ceiling. The building code requires a specific
sprinkler system. Which type is most appropriate?
A) Ordinary (12‑15 ft)
B) Extended coverage
,C) In‑rack (intermediate level)
D) ESFR (Early Suppression Fast Response)
Correct answer: D
Rationale: ESFR sprinklers are designed for high‑pile
storage of Class III commodities in buildings with
ceilings up to 45 ft.
3. After a fire, investigators determine it started in a
high‑pressure oxygen line. What is the primary
hazard of oxygen?
A) It is highly flammable
B) It lowers the autoignition temperature of materials
C) It vigorously accelerates combustion
D) It reacts explosively with water
Correct answer: C
Rationale: Oxygen is not flammable but strongly
supports and accelerates combustion of other
materials.
4. The detector that responds earliest to a
fast‑growing fire with no visible smoke is:
A) Photoelectric smoke detector
B) Ionization smoke detector
,C) Ultraviolet flame detector
D) Rate‑of‑rise heat detector
Correct answer: C
Rationale: Ultraviolet flame detectors sense the
radiant energy of a flame within milliseconds, long
before smoke or heat reaches the ceiling.
5. A 5‑story office building has open stairs that
connect all floors. The building is not sprinklered.
According to IBC, how must these stairs be treated?
A) As open exit access stairways not requiring
enclosure
B) As exit stairways that must be enclosed with
fire‑rated walls
C) As convenience stairs with no restrictions
D) As part of the building's HVAC plenum
Correct answer: B
Rationale: In unsprinklered buildings, vertical
openings must be enclosed to prevent fire spread
between floors.
6. Which extinguishing agent is most suitable for a
fire involving lithium batteries (Class D)?
, A) ABC dry chemical
B) Carbon dioxide
C) Class D dry powder (e.g., sodium chloride, copper
powder)
D) Clean agent (e.g., FM‑200)
Correct answer: C
Rationale: Class D fires require special dry powders
that smother and cool the metal without reacting.
7. The physical phenomenon by which a fire spreads
upward inside an elevator shaft, stairwell, or atrium is
called:
A) Conduction
B) Radiation
C) Stack effect
D) Flashover
Correct answer: C
Rationale: Stack effect is the vertical movement of air
due to buoyancy; it spreads smoke and fire upward
through vertical shafts.
8. A hospital's fire alarm system uses a single control
panel. After a small fire, a duct smoke detector
