Overhaul often requires complete saturation by flooding the container. Which operation is described as usually requiring this?

• A. Breakthrough
• B. Ventilation
• C. Overhaul
• D. Salvage

Answer: (C)

During overhaul, the priority is to confirm that all heat and embers have been eliminated and to prevent rekindling. Fire can smolder in hidden pockets behind walls, ceilings, and within insulation or debris. Fully saturating the space with water ensures these concealed hot spots are cooled and wetted, reducing the chance that hidden embers will re-ignite later. That need for complete saturation is why this operation is described as usually requiring flooding. Other firefighting tasks focus on access, smoke removal, or protecting belongings, not on saturating the entire space to this extent.
