B) NFPA 72
C) NFPA 101
D) NFPA 70
B) NFPA 72
Rationale: NFPA 72 is the National Fire Alarm and Signaling
Code, providing requirements for installation, testing, and
maintenance of fire alarm systems.
2. What is the primary purpose of a life safety plan?
A) To comply with building codes
B) To ensure occupant safety during emergencies
C) To reduce insurance premiums
D) To increase building aesthetics
B) To ensure occupant safety during emergencies
Rationale: Life safety plans are designed to protect building
occupants by providing clear procedures during fires or other
emergencies.
,3. Which of the following is a primary component of an effective fire
prevention program?
A) Fire drills
B) Fire extinguisher inspections
C) Risk assessment and hazard mitigation
D) Smoke detector installation
C) Risk assessment and hazard mitigation
Rationale: Identifying and mitigating fire hazards is essential to
preventing fires, which is the core of a fire prevention program.
4. How often should fire extinguishers be inspected according to
NFPA standards?
A) Monthly
B) Quarterly
C) Annually
D) Every 5 years
A) Monthly
Rationale: NFPA 10 requires visual inspections of portable fire

B) 150 feet
C) 200 feet
D) 300 feet
C) 200 feet
Rationale: NFPA 101 specifies that in fully sprinklered buildings,
the maximum allowable travel distance to an exit is generally
200 feet.
,6. What is the minimum clear width for a corridor serving as a
means of egress in most commercial buildings?
A) 24 inches
B) 36 inches
C) 44 inches
D) 60 inches
B) 36 inches
Rationale: NFPA 101 and most building codes require a minimum

C) CO2
D) Wet chemical
C) CO2
Rationale: CO2 extinguishers are non-conductive and effective

which type of facility?
A) High-rise office building
B) Healthcare facilities
C) Industrial warehouse
D) Hotel
B) Healthcare facilities
Rationale: In hospitals, patients may not be able to evacuate
quickly, so “defend in place” strategies use compartmentation
and fire barriers.
11. Which type of sprinkler system contains water in the piping
at all times?
A) Wet pipe system
B) Dry pipe system
C) Preaction system
D) Deluge system
A) Wet pipe system
Rationale: Wet pipe systems maintain water in the pipes under
pressure, allowing immediate discharge when activated.
12. Which of the following is NOT considered a life safety
