Description
A colorless, noncorrosive, and nonflammable gas that is used as a leak detecting agent and as a fire suppressant. Dichlorodifluoromethane was formerly used as an aerosol propellant and a refrigerant. Its use was banned in the late 20th century because of damage to atmospheric Ozone.
See also Chlorofluorocarbon.
