1. What is the primary purpose of a smoke control system in a
building?
A. Reduce energy consumption
B. Protect structural steel from heat
C. Control smoke movement to aid occupant evacuation
D. Improve indoor air quality
Rationale: NFPA 92 defines smoke control systems as systems
designed to limit smoke spread to facilitate safe evacuation and
firefighting operations.
2. Smoke control systems are classified into which main types?
A. Fire suppression and fire detection
B. Exhaust, pressurization, and combination systems
C. Sprinkler and standpipe systems
D. Natural and mechanical ventilation
Rationale: NFPA 92 categorizes smoke control into exhaust systems,
pressurization systems, and combination systems depending on the
method of smoke management.
3. Which of the following is a primary component of a mechanical
smoke control system?
, A. Fire extinguisher
B. Smoke exhaust fans
C. Fire hose
D. Sprinkler head
Rationale: Mechanical smoke control relies on fans to move or
pressurize air, directing smoke away from exit paths.
4. What is the minimum design objective for smoke control in exit
stairwells?
A. Maintain temperature below 200°F
B. Prevent smoke from entering for a specified duration
C. Maintain humidity below 50%
D. Keep doors unlocked
Rationale: Smoke control systems are required to keep stairwells and
exit paths smoke-free for the duration of occupant evacuation.
5. In a smoke exhaust system, what is the purpose of the smoke
reservoir or plenum?
A. Store water
B. Collect smoke to be exhausted
C. Contain sprinklers
D. Support structural loads
Rationale: The smoke reservoir temporarily holds smoke so fans can
efficiently remove it from the building.
6. Which NFPA standard primarily governs the testing of smoke
control systems?
A. NFPA 72
B. NFPA 13
C. NFPA 92
D. NFPA 101
, Rationale: NFPA 92 outlines requirements for design, installation,
testing, and maintenance of smoke control systems.
7. How often must smoke control systems undergo performance
testing according to NFPA 92?
A. Every month
B. Every 5 years
C. Annually
D. Only at installation
Rationale: NFPA 92 requires annual testing to ensure the system
functions as intended under design conditions.
8. What is a common method for controlling smoke in large
atriums?
A. Sprinkler activation
B. Mechanical exhaust and pressurization
C. Fireproofing ceilings
D. Fire doors only
Rationale: Atrium smoke control commonly uses exhaust fans at the
top and pressurized areas at lower levels to direct smoke upward and
away from occupants.
9. What is the term for a space where smoke is temporarily held
before exhaust?
A. Stairwell
B. Smoke reservoir
C. Fire zone
D. Air plenum
Rationale: A smoke reservoir is designed to contain smoke and
reduce its spread until it can be mechanically removed.
