Ozone - O3
Find here the essential information on ozone (O3 gas) – also known as trioxygen – appropriate detection equipment - O3 ozone detector - and respiratory protective equipment - gas mask or powered air purifying respirator with ABEK-P3 combined filter.
Ozone properties (O3)
Naturally present in the atmosphere, trioxygen (O3) - most commonly known as ozone - is naturally released by nitrogen oxides (NOx). Ozone is also industrially produced through electrical shocks in tubular generators. It is used for wastewater treatment (water ionization) but also for printing works (laser radiation) and arc welding with inert gases.

Ozone health effects
Ozone (O3) taint varies from colorless to blue with a bleach-like pungent smell, detectable from 0.01 ppm. Non-flammable, ozone is a strong oxidizer and can ignite explosions. Although its toxicity depends on several factors (temperature, pressure, concentration), ozone is very harmful for the breathing system (lungs, nose, throat) and can irritate the eyes.

Ozone detector - O3
Although O3 is odorous, only an ozone meter (or ozone sensor) can accurately measure concentrations of this highly toxic gas. Thus it is recommended to use the proper fixed or portable ppm ozone detection equipment.
O3 gas respiratory protection - ozone
As ozone is irritating to the eyes so it is advised to use a full face mask for short interventions, or a complete powered air purifying respirator (or PAPR), equipped with an ABEK-P3 combined filter. If concentrations exceed 60 times the OEL, a self-contained breathing apparatus (SCBA) is required.
