Ozone Gas • Reddening of skin • Headaches • Sore eyes If any symptoms appear, investigations should be carried out. First Aid Skin - No treatment can be made immediately. However, soothing cream can be applied to the affected area. Eyes - For exposure, seek medical attention immediately. Ozone is generated by the reaction of short-wave UV radiation with air. Ozone is a gas that readily reverts to oxygen when mixed with atmospheric air as it is removed from the source of UV radiation. The quantity of ozone produced equals 0.001 cu.ft/kWHr. Ozone checks using a Draeger measuring device should be carried out every 6 months, or immediately if an operator can smell ozone. Outlet duct concentration is 0.3 PPM in a typical system. The threshold limit value (TLV) is 0.1 PPM in a working atmosphere. Precautions Ozone has an irritant action on the mouth and throat and the Factory Inspectorate recommendation is that the level of ozone in the atmosphere of a factory should not exceed 0.1 PPM (TLV). Most people can smell ozone at about one third of the TLV. If there is any doubt as to whether the TLV is being exceeded, the company should take measurements to check whether the extraction system is adequate to keep the atmosphere well below 0.1 PPM. If ozone is detected: 1 Shut down the system. 2 Check the ducting for leaks. 3 Before restarting, check the working area with an ozone meter. First Aid If a person is overcome by ozone, take the following precautions: 1 Remove the patient to a warm uncontaminated atmosphere and loosen tight clothing at the neck and waist. 2 Keep the patient at rest. 3 If the patient has difficulty in breathing, oxygen may be administered provided that suitable apparatus and a trained operator are available. 4 If breathing is weak or has ceased, contact Emergency medical services immediately. 5 Seek medical aid. 15
