Documented Uses

• Used as a refrigerant, fire-extinguishing agent, and control fluid; [HSDB]
• Refrigerant, fire-extinguishing agent, control fluid
• Its use as a fire-extinguishing agent(1) may result in its direct release to the environment(SRC). However, in accordance with the the Montreal Protocol of 1987, production and consumption of this substance was to be phased out in developed nations in 1994, and is scheduled to be phased out in non-developed nations by 2010(2,3).
• Production and consumption of 1,2-dibromotetrafluoroethane in developed nations was scheduled to have been phased out by 1994 in accordance with the Montreal Protocol of 1987 since 1,2-dibromotetrafluoroethane is listed as an ozone depleting chemical.
• Manufacturing processes use hydrofluoric acid from fluorospar in production of all fluorocarbons. /Fluorocarbons/
• (2000) 10 thousand - 500 thousand pounds
