Which of the following best describes the typical layers of fire protection in a facility?

• A. Surveillance, Access Control, Alarm Monitoring, and Incident Response.
• B. Detection, Containment, Suppression, and Safe Egress/Evacuation Measures.
• C. Prevention, Detection, Alarm, and Insurance Compliance.
• D. Prevention, Protection, Patrols, and Post-Incident Review.

Answer: (B)

Fire protection in a facility is built in layered defenses that cover warning, barrier control, active response, and safe exit. Detection provides early warning through smoke and heat detectors and fire alarms, so occupants can begin to evacuate and responders can act promptly. Containment focuses on slowing or stopping the spread by compartmentalizing spaces with fire barriers and doors, keeping flames, heat, and smoke contained to reduce damage and preserve safe areas. Suppression is the active response to control or extinguish the fire, using systems like sprinklers, extinguishers, or other extinguishing media. Safe egress and evacuation measures ensure people can leave the building safely, with clearly marked exits, emergency lighting, and well-planned evacuation procedures.

These layers work together in sequence: detect early, contain the spread, suppress the fire, and get occupants to safety. Other options mix in security or administrative tasks that aren’t part of this standard fire protection framework, so they don’t describe the typical layered approach.
