Limitations

A. Ozone should not be used a high humidity areas unless dehumidified air is supplied to the generator. Ozone reacts with moisture to create hydrogen peroxide (0₃ + h₂0 = h₂0₂ and 0₂). If ozone procedures must be done in high humidity areas bleaching of fabrics and rusting of metals may occur.

B. Ozone oxidizes natural rubber (latex) products. In clothing and or other materials elastic is usually a natural rubber product. Ozone can also dry out and bleach untreated leather products. Very few appliances or products contain natural rubber. Most are made of plastic and are unaffected by ozone. (if in doubt check with the product manufacturer)

C. Ozone in high enough concentrations can be an irritant. Concentrations of 1.0 ppm (parts per million) can produce a sulfur-like odor and may cause headache, and irritation of the eyes and upper respiratory tract. These symptoms should disappear shortly after leaving the exposure area. Ozone should be used in unoccupied areas only when concentrations exceed .04 ppm. If an individual complains of eye, throat, or nose irritation when in the presence of ozone they are likely sensitive to it and should be removed from that environment. Once removed the irritation should subside. Should it persist seek medical advice.

D. Plants and animals should also be removed from areas that are to be treated with ozone.

Note: Professional technicians should never expose themselves or others to concentrations of ozone exceeding 0.04 ppm. If you can smell it in the air, you are above that level. Unlike most other cleaning products, which have caused fatalities, there are no know such incidents attributable to ozone. Used with care and the proper respect it is a wonderful tool for the cleaning professional.
