Salvage • Operations that aid in reducing primary and secondary damage during fire fighting – Primary damage is caused by the fire – Secondary damage is caused by fire suppression activities (Continued) Firefighter I 11

Salvage • Both primary and secondary damage can be minimized through salvage • Some damages cannot be avoided • Starts as soon as adequate personnel are available • May be done simultaneously with fire attack Firefighter I 12

Overhaul • Consists of operations involved in searching for and extinguishing hidden or remaining fires • Protecting the scene and preserving evidence are components of overhaul (Continued) Firefighter I 13

Overhaul • If possible, do not start overhaul operations until – Fire is under control – Fire cause has been determined – Evidence has been identified and protected Firefighter I 14

Salvage • Methods and operating procedures by which firefighters attempt to save property and reduce further damage – Removing property – Covering property – Other means (Continued) Firefighter I 15
