Preventing accidental ozone poisoning in workers.
Division of Occupational Health, 1966 Jan; :1-6
Ozone is a form of oxygen. At ordinary conditions it is a colorless or pale blue gas and has a characteristic pungent odor. In high concentrations it is extremely flammable and in liquid form it becomes a dangerous explosive. Ozone is acutely and chronically toxic to humans, and workers in enclosed spaces where ozone is produced or used should be on guard against its potential hazards to which they may be accidentally exposed. There are two general sources of exposure to ozone. Ozone is produced by the discharge of high tension electrical current in air or oxygen, such as form electrical equipment, welding operations, ultraviolet light spectrographs and plasma jet operations. Exposure to ozone may also occur form ozone generators developed for use in industrial processes. Examples of this type include ozone produced for use as a disinfecting germicide, or to control growth of fungus, molds, and bacteria in food processing.
