Ozone is a reactive, strongly oxidizing and unstable gas that, in its purest form, is explosive. It is poisonous in low concentrations. Ozone is present in low concentrations in the atmosphere, where it protects the earth from the sun's ultraviolet rays.
Ozone, O3, is formed by three oxygen atoms and has a strong and irritating odour.
Ozone is used in many different applications. In the food industry it is used to kill micro-organisms in food. Ozonated water is used for surface sanitation and product disinfection.
The major hazards of ozone is that it is very poisonous and explosive.
