Fire and Smoke Damage Behavior of Smoke A fire loss is very complex because of the unique behavior of smoke. It is important to have trained technicians at the loss location. SERVPRO franchisees know their smoke! Hot smoke migrates to cooler areas and upper levels of a structure. Smoke flows through plumbing systems, using holes around pipes to go from floor to floor. The type of smoke will greatly affect the restoration process. Types of Smoke The first step at a fire scene is to calm the fears of those affected. Next, SERVPRO tests the smoke to see which of the following types of fire took place. Wet Smoke - Low heat, smoldering, pungent odor, sticky, smeary. Smoke webs are more difficult to clean. Dry Smoke - Fast burning at high temperatures. Protein - Virtually invisible, discolors paints and varnishes. Extreme pungent odor. Fuel Oil Soot - Furnace puff backs cause fuel oil soot. Other Types - Tear gas, fingerprint powder, and fire extinguisher residue are other types. Pretesting After the type of smoke is known, pretesting on the property is performed to determine the following: What can be restored versus what can be replaced The most effective cleaning method Conditions to the property before the damage occurred The full extent of the loss Eliminate needless replacements Pretesting also allows the SERVPRO Professional to focus on saving precious items for you, and that is what really matters!
