Several aerosol propellant and related applications of fluorocarbons were examined to identify existing and technologically feasible alternatives. Associated cost factors were also considered. Interested parties brought these fluorocarbon applications to the attention of an interagency work group (EPA, FDA, and CPSC) as being possible 'essential uses' of these substances. The applications examined under the task were: flying insect insecticides, other pesticides, spray paints, air brushes, mine safety devices, mold release agents, lubricants, battery terminal protection, paper frictionalizing indicator, electronic cleaners, burglar alarm system, portable acoustic warning devices, pressurized cleaners, aerosol computer tape developer, diamond grit spray, electronic diagnostic chillers, fire alarm system, fire extinguishing agents, and drain openers.
