CFPS Building Life Safety Systems 2 — Questions and Answers
Question 1: Under NFPA 101, which occupancy classification requires the most stringent egress requirements due to occupants being unable to self-evacuate?
- Business occupancy
- Healthcare occupancy (Correct answer)
- Mercantile occupancy
- Educational occupancy
Correct answer: Healthcare occupancy
Healthcare occupancies have the most stringent egress requirements because patients may be bedridden or otherwise incapable of self-evacuation.
Question 2: What is the maximum travel distance to a stairwell exit door in a non-sprinklered high-rise office building per IBC requirements?
- 200 feet
- 250 feet (Correct answer)
- 300 feet
- 400 feet
Correct answer: 250 feet
IBC limits travel distance in non-sprinklered business occupancies to 250 feet to the nearest exit.
Question 3: A two-hour fire-rated corridor is required in which of the following building scenarios?
- A sprinklered assembly occupancy
- A non-sprinklered healthcare occupancy with sleeping rooms (Correct answer)
- A sprinklered high-rise residential building
- A non-sprinklered mercantile occupancy with fewer than 50 occupants
Correct answer: A non-sprinklered healthcare occupancy with sleeping rooms
Non-sprinklered healthcare occupancies with sleeping areas require two-hour fire-rated corridors to protect non-ambulatory occupants.
Question 4: Which system component is responsible for maintaining positive pressure in a stairwell to prevent smoke infiltration during a fire?
- Smoke exhaust fan
- Stairwell pressurization system (Correct answer)
- Return air plenum
- Corridor exhaust system
Correct answer: Stairwell pressurization system
Stairwell pressurization systems supply air to create a pressure differential that prevents smoke from entering the stairwell.
Question 5: Under NFPA 72, which notification appliance characteristic is defined as the minimum sound level required to awaken sleeping occupants?
- 55 dB at the pillow
- 75 dB at the pillow (Correct answer)
- 70 dB at the pillow
- 85 dB at the pillow
Correct answer: 75 dB at the pillow
NFPA 72 requires audible notification appliances to produce a minimum of 75 dB at the pillow level to awaken sleeping occupants.
Question 6: What is the primary purpose of a refuge area (area of refuge) in a high-rise building?
- To store fire suppression equipment
- To provide a temporary safe haven for mobility-impaired occupants awaiting assistance (Correct answer)
- To house the fire command center
- To serve as a staging area for firefighter equipment
Correct answer: To provide a temporary safe haven for mobility-impaired occupants awaiting assistance
Areas of refuge provide a protected space where mobility-impaired occupants can wait safely for evacuation assistance during an emergency.
Question 7: Which NFPA standard governs the installation of smoke control systems in buildings?
- NFPA 90A
- NFPA 92 (Correct answer)
- NFPA 101
- NFPA 13
Correct answer: NFPA 92
NFPA 92 is the Standard for Smoke Control Systems and covers design, installation, and testing of systems that manage smoke during a fire.
