Name a type of protection that is considered active fire protection.

• A. Fire detection and alarm
• B. Compartmentation
• C. Fire-resisting walls
• D. Self-closing doors

Answer: (A)

Active fire protection includes systems that take action in response to a fire, such as detecting smoke or heat and issuing alerts or triggering controls. Fire detection and alarm fits this because once smoke or heat is detected, alarms sound and occupants are warned, often coordinating a rapid response. The other options are passive protection—they’re built to resist or slow the spread of fire without requiring an active response once in place: compartmentation and fire-resisting walls create barriers, and self-closing doors help contain a fire automatically, but none of these require an active action to operate the protection in the moment.
