The Ozone Colorimetric SafeAir badge is a monitoring system designed to indicate the presence of ozone at concentrations below the permissible exposure limit. The SafeAir ozone badge detects the presence of ozone by forming a color change in the shape of an exclamation mark inside the triangle. This indication is produced by a color-forming reaction that occurs when ozone reacts with a flat indicator layer.

Ozone is a bluish gas with a pleasant, characteristic odor in concentrations of less than 2 ppm. In higher concentrations, the odor is pungent and irritating. Ozone is a severe irritant to the eyes and the mucous membranes. Long-term exposures will cause pulmonary edema (abnormal fluid buildup in the lungs) and chronic respiratory disease. OSHA and NIOSH exposure limit for ozone is 0.1 ppm (TWA). Ozone is used as a disinfectant for air and water. It is also used to bleach waxes, textiles and oils.
