Dibromofluoromethane

Dibromofluoromethane is a halomethane that is used primarily as a fire extinguisher agent. It is a colorless, nearly odorless gas, and it is one of the most effective of all the halons at extinguishing fires.

Chemical Properties

Dibromofluoromethane is a bromine compound with the chemical formula CBr2F2. It is a dense gas that is heavier than air, which allows it to effectively smother fires by displacing the oxygen around the fire. It is non-reactive and safe to use on electrical equipment.

Uses

The primary use of dibromofluoromethane is in fire suppression systems. It is particularly effective in situations where water would be damaging, such as in computer server rooms or museums. It is also used in some types of fire extinguishers.

Environmental Impact

Dibromofluoromethane is a potent ozone depleting substance. Its use has been phased out in many countries due to its potential to damage the ozone layer. Alternatives to dibromofluoromethane that are less damaging to the environment are being used increasingly.

Health Effects

Exposure to dibromofluoromethane can cause dizziness, nausea, and in high concentrations, loss of consciousness. It can also cause skin and eye irritation.
