Ozone cleaning: dangers & protective equipment - O3 PPE - …

25/08/2020· Ozone gas detector. The ozone odor is perceptible by human smell, however smell perception does not replace a clear measurement of the gas concentration in a room or an enclosed environment. To preserve workers’ health during all phases of ozone cleaning, it is therefore necessary to have equipment able to precisely measure trioxygen presence in the air. For the detection of …
