Bromochloromethane such as halon 1211 and 1301 were developed. Due to its ozone depletion potential its production was banned from January 1, 2002, at the "Eleventh Meeting of the Parties for the Montreal Protocol on Substances that Deplete the Ozone Layer". It can be biologically decomposed using the hydrolase enzyme alkylhalidase by the reaction: In the "Enter the Matrix" video game, the player can find a "Chloro-Bromo Methane Gun", which is used as a fire extinguisher. It fires a pressurized cartridge of CBM gas to put out fires. However, due to its chemical properties, firing a cartridge near people causes their
Montreal Protocol Parties every year to assess and evaluate various technical issues including evaluating nominations for essential use exemptions for CFCs and halons, and nominations for critical use exemptions for methyl bromide. TEAP’s annual reports are a basis for the Parties’ informed decision-making. Numerous reports have been published by various inter-governmental, governmental and non-governmental organizations to catalogue and assess alternatives to the ozone depleting substances, since the substances have been used in various technical sectors, like in refrigeration, air conditioning, flexible and rigid foam, fire protection, aerospace, electronics, agriculture, and laboratory measurements Under the Montreal Protocol on Substances that Deplete the Ozone
