Physical description & handling notes

• Methyl fluoride (or fluoromethane) is a colorless flammable gas which is heavier than air. It has an agreeable ether-like odor. It is narcotic in high concentrations. It burns with evolution of hydrogen fluoride. The flame is colorless, similar to alcohol. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.

GHS Hazard Classification

Reported hazard statements	H220 (99.2%), H280 (99.2%)

Documented Uses

• Hydrofluorocarbons are increasingly being used as substitutes for chlorofluorocarbons, e.g., refrigerants, propellants in aerosols, and blowing agents for foams; they do not deplete the ozone layer of the atmosphere. [Ullmann]
