Smoke damage cannot be overestimated. It requires expertise in removing debris, shoring and bracing, board-up, and tarping for safety. Outbreaks can give off harmful carcinogens and chemicals that, though silent and often unseen, can be tremendously dangerous for your staff’s health. This is especially true for people with sensitive breathing.
Soot, on the other hand, is acidic, a byproduct of incomplete combustion that can contain Polycyclic Aromatic Hydrocarbons (PAH) which is considered carcinogenic and can cause further damage if not removed soon after a fire.
In a fire event, smoke and soot affect floors, walls, upholstery, ceilings, even HVAC units, and air ducts which spread damage and harmful gases across the entire building. If the central heat and air system was on during the fire or was turned on after the fire, it can carry soot to other parts of the building, spreading not only to physical damage but dangerous gases.
