CNA Certification (Written Exam)Infection Control and SafetyMedium
During a fire evacuation drill, staff members are taught to close all doors behind them as residents are moved to safety. What is the primary purpose of this action?
- ATo prevent residents from re-entering their rooms
- BTo keep noise levels down during the evacuation
- CTo slow the spread of smoke and fire to other areas
- DTo conserve air conditioning within the building
Show answer & explanationAnswer & explanation
Correct answer: C. To slow the spread of smoke and fire to other areas
Closing doors during a fire helps contain smoke and flames within a room or section, slowing their spread and protecting areas not yet affected, which supports safe evacuation. This is a core principle of fire safety and part of the Confine step embedded in facility fire protocols.
Why the other options are wrong
- A. Preventing re-entry is a secondary effect, not the main safety purpose.
- B. Noise control is not the purpose of closing doors during a fire.
- D. Energy conservation is irrelevant during an emergency evacuation.
Fire Containment (Confine Step)
Closing doors during a fire emergency to slow the spread of smoke and flames, protecting unaffected areas of the building.
- Part of the RACE fire protocol (Confine)
- Closed doors act as physical barriers against smoke/fire
- Helps buy time for full evacuation
Memory trick: Shut the door, slow the fire — buy time to get everyone out.
