Which statement correctly distinguishes active versus passive fire protection?

Which statement correctly distinguishes active versus passive fire protection?

• A. Active protection is not necessary in many buildings
• B. Active protection involves a proactive response to detect, control, or extinguish fire.
• C. Passive protection uses alarms and sprinklers
• D. Active protection only applies to outside structures

Answer: (B)

Active protection relies on systems that require energy or action to respond to a fire, such as alarms, detection systems, and automatic extinguishing devices. Passive protection, on the other hand, is built into the structure itself to resist fire without needing active systems—things like fire-rated walls and doors, seals, and compartmentalization that slow or contain spread. The statement that describes active protection as a proactive response to detect, control, or extinguish fire matches this distinction because it emphasizes the action-oriented, system-driven response to a fire event. The other options don’t fit: alarms and sprinklers are active protections, not passive; active protection is not limited to outside structures, since many buildings rely on active systems inside as well; and claiming active protection isn’t necessary in many buildings ignores the complementary use of both active and passive measures in effective fire safety.
