The hazards associated with industrial exposure to ozone (10028156) were discussed in this pamphlet. Topics included the characteristics of ozone, industrial uses of ozone, occurrence of ozone, health risks of ozone exposure, exposure control, symptoms, management responsibilities, and employee responsibilities. Ozone has been used industrially to age wood rapidly, age liquor, dry varnish, produce peroxides, bleach oils, and deodorize feathers. It has been used as a disinfectant for water supplies, industrial wastes, and food products. Ozone could be produced from oxygen by an electrical discharge in the air or by photochemical reactions with ultraviolet radiation. Ozone exposure caused irritation of the throat, headaches, coughing and pain in the chest. It impaired the sense of smell, altered taste, reduced the ability to think clearly, depressed the nervous system and slowed the heart and respiration. An adequate ventilation and exhaust system should be in place wherever ozone is suspected of forming. Management has the responsibility of instituting hazard controls for ozone exposures and maintaining a proper medical program. The employee should be aware of the possible dangers, avoid exposure to ozone in poorly ventilated areas, be certain that the ventilation system is working, wear recommended protective gear, cooperate with management regarding medical examinations, report symptoms of exposure, and alert any physician seen about ozone exposure.
