Top toxic materials found in smoke and soot during fire restoration:
Asbestos fibers, which can cause Mesothelioma (cancer), are found in building materials used in the 1950s-1980s. If your home was built during this time there is a good chance it would contain these asbestos fibers.
Carbon, which can be found in many household items, can produce carbon monoxide, hydrogen, ammonia, nitrogen oxides, and tar.
PVC used throughout the home may create hydrogen chloride, phosgene, dioxin, chloromethane, bromomethane, and halocarbons.
Sulfur may form hydrogen sulfide, sulfur dioxide, and thistles that can cause residual smoke odor.
