Ozone is an irritant to the lungs, eyes, and mucosal tissues. The NIOSH recommended exposure limit for ozone is 0.1 ppm (0.2 mg/m 3). Ozone treatment We recommend you ozonate a glass of distilled water for about 10 minutes, which will fully saturate it. Water Ozonation Safety ... Ozone Offgassing The main safety procedure is to make sure that high concentrations of ozone gas is not released into the room or building as it will have a negative impact on people, pets, and plants.

One of the primary benefits of ozone is that it is known to destroy pathogens. Ozone (O 3) owes its biocidal effectiveness to its ability to oxidise organic materials in bacterial membranes, which weakens the cell wall leading to rupture and immediate death of the cell.
