Which firefighting strategy requires restricting the use of water hoselines, especially at the area of origin?

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

Answer: (A)

During overhaul, the focus is on locating and extinguishing hidden pockets of fire while carefully examining the scene to prevent rekindling and preserve evidence. Limiting water use at the area of origin helps achieve this by reducing water damage and avoiding disturbance that could obscure the ignition source or other forensic details. Water can wash away or spread evidence, flood the area, or alter burn patterns, making it harder to determine how the fire started. By restricting hoseline use in the origin area and directing cooling efforts where necessary, investigators can more accurately assess the cause while ensuring the scene remains as intact as possible. This approach contrasts with other strategies: ventilation is about smoke control and can involve independent water considerations, suppression is active fire attack where water use is the primary tool, and salvage focuses on protecting property, not on preserving the origin for investigation.
