Containing chlorofluorocarbons

Chlorofluorocarbons (CFCs). Prior to 1978 most aerosol products contained chlorofluorocarbon propeUants. Since that time, the use of chlorinated fluorocarbons for aerosols has been seriously curtailed. These compounds have been impHcated in the depeletion of the ozone (qv) layer and are considered to be greenhouse gases (see Airpollution Atmospheric modeling). 

Some physicians recommend epinephrine metered-dose inhalers as an alternative to epinephrine autoinjectors. While a few inhalations might relieve mild or moderate respiratory symptoms, for relief of life-threatening airway obstruction or shock, adults need to inhale 20-30 puffs and children need to inhale 10-20 puffs, which is hard to do [35]. Epinephrine metered-dose inhalers contain chlorofluorocarbon propellants. For environmental reasons, they might not be manufactured in the future.

Some states draw their prohibitions more narrowly. New Jersey, for instance, prohibits selling or offering to sell minors products containing chlorofluorocarbon that is used in refrigerant. 

In the USA, the Environmental Protection Agency (EPA) additionally requires the following information on all aerosols containing chlorofluorocarbons as the propellant ... 

Chlorodifluoroethane is usually encountered as a liquefied gas and appropriate precautions for handling such materials should be taken. Eye protection, gloves, and protective clothing are recommended. Chlorodifluoroethane should be handled in a well-ventilated environment. Chlorofluorocarbon vapors are heavier than air and do not support life therefore, when cleaning large tanks that have contained chlorofluorocarbons, adequate provisions for oxygen supply in the tanks must be made in order to protect workers cleaning the tanks. 

A different result, however, was reached in United States v. Falcon Safety Products (D.N.J. January 27,1981). In that case, the District Court upheld the Commission s use of Section 27(e) to require a warning for all aerosolized consumer products containing chlorofluorocarbon propellants. The Commission s warning, which was similar to warnings adopted by the Food and Drug Administration and the Environmental Protection Agency for products within their jurisdictions, stated as follows ... 

Pbarmaceutical PropeUants Many inhaled medications used to treat asthma contained chlorofluorocarbon (CFC). However, the Montreal Protocol called for a ban ofCFCs as a propellant in pharmaceutical products by 2008. Two hydro-fluoroalkanes (HFAs) appear to be effective in delivering asthma medications to the lungs. However, the medication dosage had to be cut in half with the new HFA propellents. 

Existing pMDIs contain chlorofluorocarbon (CFCs) propellants. These are a class of organic chemicals containing chlorine, fluorine, and carbon. The main... 

Both the aerosol sprays and the aerosol foam products originally tended to contain chlorofluorocarbons (CFCs) like Freon as the pressurized propellant phase (which in foam applications becomes the dispersed gas phase). With increasing environmental awareness and concerns, formulation practices have changed in... 

Paint removal is accomplished by either chemical or blast depainting. Dichloromethane is the most common solvent used for this application. Aerospace industry estimates that 15,000 to 30,000 different materials are used for manufacturing some of which are potentially toxic, volatile, flammable, and contain chlorofluorocarbons. Some of these substances may result in air emissions, waste-waters, and solid waste. 

Hydrohalocarbons are hydrogen-containing chlorofluorocarbons (HCFCs) and hydrogen-containing fluorocarbons (HFCs) that are now produced as substitutes for chlorofluoroearbons. These eompounds include CH2FCF3 (HFC-134a, a substitute...
