Often referred to as O3, ozone is a gas with an antiseptic smell and no colour that, mostly, forms naturally in the environment. It is the substance prevalent within the ozone layer; a protective shield that stops the sun’s harmful rays (UV-B) penetrating to the earth’s surface and damaging life on the planet.
Emitted from vehicles, industrial facilities, plants, household supplies, cleaning products and refineries.
Colourless gas that is difficult to trace without an effective detection system in place.
On exposure a person should be taken to a warm and uncontaminated environment and given looser clothing.
