Ozone ^O₃

Hazard pictograms

Ozone (O3) plays a crucial role in the atmosphere, particularly in the ozone layer, where it protects against the sun’s UV rays. Ozone is also found closer to the Earth’s surface and is formed as a result of chemical reactions between various air pollutants, especially nitrogen oxides and organic compounds in sunlight.

Ozone is a highly toxic gas and is typically used in the pharmaceutical industry, laboratories, and educational institutions. Ozone affects the respiratory system, and exposure typically causes burning and pain in the nose, mouth, throat, and airways, along with fatigue and palpitations.

It is therefore important to understand the characteristics of ozone and act proactively to ensure a healthy and safe working environment.
