California Fire Prevention Officer
Examination with Practice Questions And
Correct Answer
1. During a routine inspection of a high-rise office building, you observe that a
stairwell door is propped open with a wooden wedge. The door is equipped with a
magnetic hold-open device that releases upon fire alarm activation. Which of the
following violations under the California Fire Code is most appropriate?
A. Obstructing a means of egress
B. Failure to maintain fire door assembly
C. Improper storage in exit enclosure
D. Deficient fire alarm initiation
Answer: B. Failure to maintain fire door assembly
Rationale: The door is a fire door assembly; propping it open defeats its fire-resistance
rating, violating CFC Section 703.2. While it also obstructs egress, the primary violation is
failure to maintain the fire door assembly. The hold-open device is functioning correctly, so
it is not a fire alarm issue.
2. A plan review for a new assembly occupancy with an occupant load of 1,200 reveals
a single main exit. According to the California Building Code, what is the minimum
number of exits required?
A. 2
B. 3
C. 4
D. 1 if sprinklered
Answer: C. 4
Rationale: CBC Table 1006.3.2 requires at least 4 exits for an occupant load of
1,001-1,200 in assembly occupancies. Two exits are insufficient for this load; three is below
the threshold; and sprinklers do not reduce the required number of exits.

,3. A fire investigation reveals a pattern of charring on a floor joist that is deepest on
the underside and decreases toward the top. This pattern most likely indicates:
A. The fire originated above the joist
B. The fire originated below the joist
C. The fire burned laterally across the joist
D. The fire was ventilation-limited
Answer: B. The fire originated below the joist
Rationale: Char depth is greatest on the side exposed to the fire; deeper char on the
underside indicates the fire was below the joist. Lateral burning would produce uniform
char, and ventilation-limited fires do not produce this specific directional pattern.
4. When calculating the required fire flow for a building using the California Fire
Code, which factor is NOT considered in the formula?
A. Building construction type
B. Occupancy hazard classification
C. Sprinkler protection
D. Distance to nearest hydrant
Answer: D. Distance to nearest hydrant
Rationale: The fire flow formula in CFC Appendix B considers construction type,
occupancy, and sprinkler protection. Distance to the nearest hydrant is used for hydrant
placement and water supply analysis, but it is not a variable in the fire flow calculation
itself.

,5. An inspector finds a 55-gallon drum of flammable liquid stored in a warehouse
without secondary containment. The drum is labeled 'Acetone.' Which hazard class
does acetone fall under, and what is the maximum allowable quantity per control area
for a non-sprinklered storage area?
A. Class IB, 120 gallons
B. Class IC, 120 gallons
C. Class IB, 60 gallons
D. Class IC, 60 gallons
Answer: A. Class IB, 120 gallons
Rationale: Acetone has a flash point of -20°C and boiling point of 56°C, making it a Class
IB flammable liquid. CFC Table 5003.1.1(1) allows 120 gallons of Class IB liquids in a
non-sprinklered control area. Class IC and lower limits are incorrect.
6. A fire prevention officer is developing a public education campaign targeting a
community with a high incidence of unattended cooking fires. Which of the following
strategies is most effective based on NFPA's community risk reduction model?
A. Distributing pamphlets at a local fair
B. Conducting a door-to-door smoke alarm installation program
C. Hosting a fire extinguisher training at a community center
D. Broadcasting public service announcements on radio
Answer: B. Conducting a door-to-door smoke alarm installation program
Rationale: NFPA's community risk reduction model emphasizes direct intervention for
high-risk populations. Door-to-door programs allow personalized education and
immediate risk reduction (smoke alarms), which is more effective than passive methods like
pamphlets or PSAs. Extinguisher training is less directly tied to unattended cooking.

, 7. During a plan review for a new hazardous materials storage facility, the applicant
proposes a 2-hour fire-rated separation between a Class I flammable liquid storage
room and an adjacent office area. The building is fully sprinklered. Is this acceptable?
A. Yes, 2-hour separation is always required.
B. No, 1-hour separation is sufficient when sprinklered.
C. Yes, but only if the office is not occupied.
D. No, separation is not required if sprinklered.
Answer: B. No, 1-hour separation is sufficient when sprinklered.
Rationale: CFC Table 5003.1.1(1) allows a 1-hour separation for Class I liquids in
sprinklered buildings. A 2-hour rating is overly restrictive; omitting separation entirely is
not permitted. Occupancy of the office does not change the requirement.
8. An inspector observes that a commercial kitchen hood suppression system has not
been serviced in 8 months. According to NFPA 96, what is the required inspection
frequency for this system?
A. Monthly
B. Quarterly
C. Semi-annually
D. Annually
Answer: C. Semi-annually
Rationale: NFPA 96 requires semi-annual inspection and servicing of hood suppression
systems. Monthly and quarterly are too frequent, while annual is insufficient for this
high-hazard equipment. The 8-month gap represents a violation.
