FDA-Anforderungen	The Food and Drug Administration (FDA), after consultation with the Environmental Protection Agency (EPA), is amending FDA's regulation on the use of ozone-depleting substances (ODSs) in selfpressurized containers to remove the essential-use designations for flunisolide, triamcinolone, metaproterenol, pirbuterol, albuterol and ipratropium in combination, cromolyn, and nedocromil used in oral pressurized metered-dose inhalers (MDIs). The Clean Air Act requires FDA, in consultation with the EPA, to determine whether an FDA-regulated product that releases an ODS is an essential use of the ODS. FDA has concluded that there are no substantial technical barriers to formulating flunisolide, triamcinolone, metaproterenol, pirbuterol, albuterol and ipratropium in combination, cromolyn, and nedocromil as products that do not release ODSs, and therefore they will no longer be essential uses of ODSs as of the effective dates of this rule. MDIs for these active moieties containing an ODS may not be marketed after the relevant effective date. DATES: Removal of Part 2.125(e)(2)(iii) and 2.125(e)(4)(vii) is effective June 14, 2010. Removal of Part 2.125(e)(1)(v) and 2.125(e)(4)(iv) is effective December 31, 2010. Removal of Part 2.125(e)(1)(iii) is effective June 30, 2011. Removal of 2.125(e)(2)(iv) and Part 2.125(e)(4)(viii) is effective December 31, 2013. /Ozone-Depleting Substances/

Anwendungen & Verwendung

Beschreibung

Trichlorofluoromethane is a chlorofluorocarbon (CFC) which is commonly used as a refrigerant, a foaming or blowing agent in industry, a solvent, an aerosol propellant, and in chemical syntheses.Trichlorofluoromethane is a colorless, odorless gas at normal temperatures and pressures. Under high pressures as in cans, tanks or refrigerators it is in liquid form. When released from a pressurized container it evaporates almost instantly and can cause freezing at the point of release. At very high concentrations in air it may smell like ether. It is slightly soluble in water but evaporates quickly if exposed to air. The chemical formula for Trichlorofluoromethane is CFCL3.

Occurrence

Trichlorofluoromethane is man-made and its presence in the environment is due to releases from common household and industrial uses. It is extremely stable in the atmosphere and does not degrade naturally. It can also be produced as an industrial by-product wherever chlorine products are used; including small quantities which are formed by reaction of chlorine disinfectants with organic pollutants in water. It is released into the air by leaking refrigeration units and air conditioners and by spray paint, spray varnish, spray cosmetics and other sprays in which it has been used as a propellant. Since 1978 many uses of trichlorofluoromethane as a propellant have been prohibited by law in the U.S. It can still be used as a propellant in some specialized products used in businesses and industries. It may also be found in air emissions and waste waters from a number of industries particularly refrigeration, electronics and foam manufacturing.

Verwenden

Trichlorofluoromethane is a coolant in conditioning systems. It is a bulking agent for polymer foams. It is also used as a degrease solvent for printed circuit boards and to dry clean textiles. It is used as an aerosol propellant in various industries.
