Abstract: A system for deodorizing and decontaminating autopsy rooms where autopsies are conducted on decomposed human remains wherein large amounts of noxious and malodorous gases are given off comprising an exhaust fan for removing large volumes of air and noxious gases substantially instantaneously from the specific autopsy environment and directing the air and noxious gases to a chamber, a burner associated with the chamber such that the flammable decomposition gases being exhausted are bombarded by a flame, ignited, burned and deodorized, and a duct associated with the chamber for directing the air and burned gases to the exterior of the building.
