CFC's (chlorofluorocarbons) and HCFC's (hydrochlorofluorocarbons) were used extensively as refrigerant gases and aerosol propellants since the 1930's, until they were identified as ozone depleting substances (ODS) and phased out in accordance with the Montreal Treaty, signed by 180 countries in 1987.
Halon gases were used as fire suppressants and extinguishers in Australia from the early 1970's, until a complete ban on their use in new equipment in most jurisdictions in 1995. Halon gases are very damaging to ozone, and considered to be 10 times worse than CFC's.
Halons, CFC's and HCFC's have also been shown to present human health effects, particularly on the respiratory tract.
HFC's (hydrofluorocarbons) were introduced as a non-ozone depleting refrigerant, but were since identified as a potent synthetic greenhouse gas (SGG).
Handling, use, storage & disposal of halons and refrigerant gases is strictly controlled in Australia.
BENSS provides Halon & Refrigerant Gas Identification; Risk Assessments & Management Plans for in-use equipment; and advice on safe removal and disposal.
