The chlorofluorocarbons (CFC) used in refrigeration systems decompose on heating and produce substances that are highly irritating to the airways (eg, chlorine, carbonyl fluoride, and hydrogen fluoride). This study examined persistent respiratory symptoms among several workers exposed to thermal decomposition products of CFC.
