Fire Loss in large warehouse.
Warehouses often suffer fire damage. They house chemicals, equipment, and other storage items that are flammable. During extreme heat all the materials start to let off a gas that can be ignited with a single spark. This warehouse suffered this exact scenario causing the black soot to coat the walls.
The first picture shows an area where the smoke penetrated through the ceiling escaping under the ceiling tiles. The second picture shows our crews working through the inner halls removing ceiling tiles and cleaning walls.
It is important to always clean from the top down when dealing with soot to assure that clean areas do not get dirty once more.
