건강 유해성	Excerpt from NIOSH Pocket Guide for 1,1,1,2-Tetrachloro-2,2-difluoroethane:
유해성 요약	Rats exposed to 10,000 ppm for 2 hours show signs of intoxication. At 20,000 to 30,000 ppm, all rats die within 1.5 to 2 hours. There are signs of kidney and liver injury, but no signs of pulmonary injury. [ACGIH] See CHLOROFLUOROCARBONS
FDA 요건	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/
