Description
A, pungent, reactive gas that exists as an allotropic form of Oxygen containing three atoms. Ozone is produced when an electric spark, lightening, or ultraviolet light is passed through air or oxygen. It is found in the lower atmosphere in minute quantities especially after a thunderstorm. In the upper atmosphere, it absorbs ultraviolet rays, preventing them from reaching the surface of the earth. Ozone is a powerful oxidizing agent. It is used for bleaching waxes, textiles, oils as well as for sterilization and disinfection. Ozone readily oxidizes organic materials such as Rubber, cellulosics, and proteins along with some inorganic materials such as Marble, Limestone, and frescos. Potential sources of ozone in indoor environments are old style electrostatic copy machines, electrostatic precipitator type air filtration units, and arc welders.
