Ozone - O3
This page brings together the main information concerning ozone (O3) or "trioxygen", its physical characteristics, its effects on health, the means of detecting it (O3 gas detector) as well as the appropriate respiratory protection equipment (gas mask or assisted ventilation device with combined filter type ABEKHg-P3 ).
Main characteristics of ozone (O3)
Naturally present in the atmosphere, " trioxygen " (O3), better known as ozone, is a gas naturally released by the release of nitrogen oxides (NOx). On an industrial scale, ozone is produced by electrical discharges in tubular generators. It is found in water treatment for its oxidizing properties (ozonization of water) but also in printing works (laser radiation) and arc welding activities with inert gases.
Health effects of ozone
Ozone (O3) is a colorless to bluish gas with a pungent odor reminiscent of bleach, detectable from 0.01 ppm. Non-flammable , ozone has a strong oxidizing power , which can be a source of explosions. Although its toxicity depends on several factors (temperature, pressure, concentration), ozone is a very harmful gas for the respiratory tract (lungs, nose and throat) and irritating to the eyes.
O3 (Ozone) gas detection
Although ozone is an odorous gas, only an O3 gas detector can accurately measure the concentrations of this extremely toxic gas, so we will move towards portable or fixed ozone fluoride detection in ppm.
Ozone (O3) respiratory protection
Ozone is an eye irritant, so a full-face mask is recommended for short-term interventions or a more comfortable assisted ventilation device with combined filters such as ABEKHg-P3. If concentrations exceed 60 times the OEL, an isolating breathing apparatus will be essential.
