Secondary damage is caused by which of the following?

• A. The fire itself
• B. Firefighting actions such as water, ventilation and overhaul
• C. Wind damage
• D. Earthquake damage

Answer: (B)

Secondary damage comes from the actions taken to fight the fire, not from the flames themselves. Water used to extinguish the fire can saturate structure and contents, create electrical hazards, and promote mold or deterioration. Ventilation changes can rearrange heat and smoke, potentially exposing additional areas to damage if not carefully managed. Overhaul involves opening walls and other materials, which can cause additional physical damage while ensuring all hidden embers are found. In short, the firefighting process itself can create damage beyond the initial fire, making firefighting actions the source of secondary damage.
