Ansul is a corporation headquartered in Marinette, Wisconsin that manufactures fire suppression systems, extinguishers, and administers fire training. Ansul's initial activities included production of cattle feed, refrigerants and selected specialty chemicals. The name Ansul comes from ANhydrous SULfur dioxide (SO₂), which was sold to die works and fruit preservers, and later as a refrigerant.^[5] Production of fire suppression chemicals began in 1934. Virginia Chemicals, Inc. (now part of Celanese Corporation) acquired the Refrigeration and Air Conditioning Products Division of The Ansul Company in 1967,^[6] and by 1983 Ansul had discontinued all other production at the facility in Marinette. The US government is a major customer for Ansul.^[4][7]

The ANSUL name is a premium brand of Tyco Fire Protection Products. The full line of ANSUL special hazard fire protection products includes fire extinguishers and hand line units; pre-engineered restaurant, vehicle, and industrial systems; sophisticated fire detection/suppression systems, and a complete line of dry chemical, foam, and gaseous extinguishing agents.^[8] A common hand-held fire extinguisher produced by Ansul is the SENTRY brand stored-pressure fire extinguisher.^[9]
