Bromochlorofluoromethane

Bromochlorofluoromethane is a type of halocarbon that is often used in fire suppression systems. It is a colorless, non-flammable gas that is heavier than air and has a slightly sweet odor. It is also known by its CAS number, 353-59-3, and its trade name, Halon 1211.

Chemical Properties

Bromochlorofluoromethane is a halogenated hydrocarbon that is made up of one carbon atom, one bromine atom, one chlorine atom, and one fluorine atom. It has a molecular weight of 165.36 g/mol and a boiling point of 3.7°C (38.7°F). It is soluble in alcohol and ether, but not in water.

Uses

Bromochlorofluoromethane is primarily used in fire extinguishers and fire suppression systems. It is effective at suppressing fires because it interferes with the chemical reaction that allows a fire to burn. However, due to its potential to deplete the ozone layer, its use is being phased out in many countries.

Health Effects

Exposure to bromochlorofluoromethane can cause dizziness, nausea, and headache. In high concentrations, it can cause unconsciousness and even death. It is also a potential carcinogen.

Environmental Impact

Bromochlorofluoromethane is a potent greenhouse gas and can contribute to global warming. It also has the potential to deplete the ozone layer. As a result, its production and use are regulated under the Montreal Protocol.
