Ozone has been known for almost a century now, so quite a lot is known about it. Several regulatory agencies, including OSHA Occupational safety and health agency - have stipulated that the safe allowable level of residual is .1 ppm based upon the historical safety of ozone. Note that this permissible level is for continuous exposure throughout an entire 8 hour day for 5 days a week. If anyone is exposed to that concentration of ozone, it is usually as the by-product of an industrial process like arc- welding. The temporary affects of such a low exposure would range from headaches, to sore throats, irritation in the eyes, nose and the like, similar again to what we would experience in a traffic jam. In almost a century of use however, there has never been a worker's compensation claim resulting from ozone exposure.
