Useful:

• Chemical Classes: Pesticides -> Fumigants
• Canonical SMILES: O=S(=O)(F)F
• Inhalation Risk: A harmful concentration of this gas in the air will be reached very quickly on loss of containment.
• Effects of Short Term Exposure: Rapid evaporation of the liquid may cause frostbite. The substance is severely irritating to the respiratory tract. The substance may cause effects on the central nervous system. This may result in convulsions and respiratory failure. Inhalation of high concentrations may cause lung oedema. The effects may be delayed. Exposure could cause death.
• Uses: Sulfuryl fluoride is another promising chemical, which is widely used for control of termites, and stored-product insects. This chemical shows considerable promise and is undergoing registration procedures as replacement for methyl bromide in several countries including the United States, Great Britain, Italy, and France. The fumigant has vapour pressure of about ten times higher (13,442 mm of Hg at 25oC) than that of methyl bromide and hence it is more penetrative into treated commodities which is a significant benefit in situations where insect infestations are located deep within cracks or machinery in premises such as flour mills . The fumigant has several other advantages as a replacement for methyl bromide; it is nonreactive with structural materials and components of electronic equipment, is non flammable and has not caused problems of taint following treatment of a wide range of materials. However the sulfuryl fluoride was found to be less effective in controlling the insect eggs. Insect fumigant Fumigant insecticide; termiticide.
