Which of the following is identified as an equipment deficiency hazard related to lighting?

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

Answer: (B)

The key idea is that lighting problems create hazards by undermining safety signaling equipment. Fire alarms are a crucial life-safety signaling device that people rely on to know when to evacuate. If lighting is deficient, these signals may not be easily seen or located, which can delay or prevent a proper response. In safety practice, a deficiency in lighting that affects the effectiveness of warning systems like the fire alarm is categorized as an equipment deficiency hazard, because the equipment itself (the fire alarm system) is compromised by inadequate lighting.

Emergency lights are themselves lighting devices, so they clearly relate to lighting hazards, but the focus here is on how lighting shortfalls impair the signaling that fire alarms provide. Fire extinguishers and self-contained breathing apparatuses are not primarily tied to lighting concerns, so they don’t fit this specific category.
