CFM CFM Life Safety & Egress Systems 2 — Questions and Answers
Question 1: Emergency lighting in a means of egress must provide a minimum illumination of how many foot-candles at floor level per NFPA 101?
- 0.1 foot-candle
- 1 foot-candle (Correct answer)
- 5 foot-candles
- 10 foot-candles
Correct answer: 1 foot-candle
NFPA 101 requires emergency lighting to provide a minimum of 1 foot-candle at floor level along the path of egress for 90 minutes after power failure.
Question 2: What is the primary purpose of a fire door assembly in a means of egress?
- To prevent sound transmission between occupancies
- To compartmentalize fire and smoke to protect the egress path (Correct answer)
- To provide additional structural support to exit corridors
- To meet ADA accessibility requirements for door hardware
Correct answer: To compartmentalize fire and smoke to protect the egress path
Fire door assemblies create barriers that prevent fire and smoke from penetrating exit enclosures and corridors, protecting occupants during evacuation.
Question 3: Delayed egress locks are permitted under NFPA 101 in certain occupancies provided the delay does not exceed:
- 10 seconds
- 15 seconds
- 30 seconds (Correct answer)
- 60 seconds
Correct answer: 30 seconds
NFPA 101 permits delayed egress locks with a maximum 30-second delay (15 seconds in some occupancies) provided specific detection and alarm conditions are met.
Question 4: In a high-rise building, which system works with the fire alarm to direct occupants to use stairwells by controlling elevator recall?
- Standpipe booster pump
- Firefighters' emergency operations (Phase I recall) (Correct answer)
- Pressurization fan system
- Stairwell communicator
Correct answer: Firefighters' emergency operations (Phase I recall)
Phase I elevator recall automatically returns all elevators to the ground floor (or alternate recall floor) when the building fire alarm activates, preventing occupants from using elevators during a fire.
Question 5: What is the maximum number of egress doors that may require a single additional releasing operation (e.g., a latch) in addition to the door's normal hardware on an egress door per NFPA 101?
- Zero — no additional hardware is permitted
- One additional releasing operation (Correct answer)
- Two additional releasing operations
- Three additional releasing operations
Correct answer: One additional releasing operation
NFPA 101 allows egress doors to require no more than one additional releasing operation beyond the normal latch operation to ensure escape is not impeded by complex hardware.
Question 6: Stairway enclosures that serve more than three stories in a non-sprinklered building must have a minimum fire resistance rating of:
- 30 minutes
- 1 hour
- 2 hours (Correct answer)
- 3 hours
Correct answer: 2 hours
NFPA 101 requires stairway enclosures serving more than three stories in non-sprinklered buildings to have 2-hour fire resistance-rated construction.
