Which of the following is a factor that involves deficiencies in equipment or the facility's structure?

• A. Fire alarms
• B. Emergency lights
• C. Fire extinguishers
• D. Self contained breathing apparatuses

Answer: (B)

Deficiencies tied to equipment or the facility’s structure refer to problems with the building’s own systems or permanent infrastructure. Emergency lights are part of that life-safety infrastructure; if they’re not working, the exit paths and visibility during an emergency are compromised, signaling a facility-level deficiency. The other items—fire alarms, fire extinguishers, and self-contained breathing apparatuses—are individual pieces of equipment used by people, so issues with them are equipment-specific rather than failures of the building’s structure or permanent systems.
