During overhaul, removing ceiling tiles helps firefighters by providing access to:

• A. Ventilate smoke
• B. Expose electrical wiring
• C. Improve lighting
• D. Locate hidden fire

Answer: (D)

During overhaul, the goal is to ensure there are no hidden pockets of fire that could rekindle. Removing ceiling tiles opens the space above the finished ceiling—the ceiling plenum—and lets crews directly inspect for heat, smoke, and embers tucked in insulation, between joists, or in other concealed voids. By exposing these areas, they can locate and extinguish hot spots that aren’t visible from below, reducing rekindle risk and making the fire fully out.

This is the best answer because it aligns with overhaul’s purpose: sweeping concealed areas for hidden fire and ensuring complete extinguishment. Other potential benefits like venting smoke or brighter lighting can occur, but they’re not the primary reason for removing ceiling tiles, and exposing electrical wiring isn’t the objective and carries its own hazards.
