Y1 - 2018 N1 - T2 - Poisoning & Drug Overdose, 7e AB - Methyl bromide, a potent alkylating agent, is an odorless, colorless, extremely toxic gas used as a fumigant in soil, perishable foods, cargo containers, and nonresidential buildings. Commercially known as Halon 1001, methyl bromide was used (until the 1960s) as a refrigerant and fire extinguisher. Fields or buildings to be fumigated are evacuated and covered with a tarp, and the gas is introduced. After 12–24 hours, the tarp is removed, and the area is ventilated and then tested for residual methyl bromide before reoccupation. Methyl bromide is a major source of ozone-destroying bromine in the stratosphere, and most production and use were scheduled to be phased out by 2005 in developed countries and by 2015 in developing countries; however, it is still being used in the United States owing to EPA critical use exemptions.
