Occupational implications of the chlorofluorocarbon ban in Sweden.

Limitations on the use of full halogenated chlorofluorocarbons (CFCs) may create occupational environmental problems. These are currently largely unknown, because the toxicology of most CFC substitutes is unknown. Therefore, toxicity testing of CFC substitutes is necessary, and this can best be done before their use commences. Destruction of CFC and materials containing CFC could generate new chemical compounds, especially during incineration. In addition, problems with higher noise and vibration levels may occur when CFC substitutes are employed, and we should keep in mind that occupational environment problems could also develop when new routines are introduced for transporting, storing, and handling new materials.
