0 a type of gas used especially in aerosols (= containers that force out liquids in very small drops) -- 氫氟氯碳化物
Where a leak occurs or major maintenance work is being undertaken in equipment which uses chlorofluorocarbons or hydrochlorofluorocarbons, these are replaced by ozone-friendly refrigerants.
Information on emissions of ozone-depleting substances from the sectors concerned or on companies which view hydrochlorofluorocarbons to be the only alternative is not available.
In particular, there are proposals for an earlier phase out of methyl bromide, to introduce controls on the production of hydrochlorofluorocarbons and to ban the sale and use of chlorofluorocarbons.
The use of chlorofluorocarbons and hydrochlorofluorocarbons within the department continues to be reduced, with the aim of total elimination within the time scale of the protocol.
We will be seeking to obtain agreement to limit production to the minimum necessary to meet demand for hydrochlorofluorocarbons in uses where ozone-benign alternatives are not available.
