What is ozone poisoning?

Ozone is an allotrope of oxygen and consists of three oxygen atoms. This is a light blue gas with a pungent smell. When the concentration is low, it is harmless to human body. If the concentration is higher than 100ppm, it will cause respiratory disorder and headache, which is called ozone poisoning.

Ozone (O), also known as peroxide, is an allotrope of oxygen (O). It is a light blue gas at room temperature and has a special smell. Ozone is mainly distributed in the stratospheric atmosphere at the height of 10~50km, and the maximum value is between 20~30km. Under normal temperature and pressure, it has poor stability and can be decomposed into oxygen by itself.

Ozone is a harmful gas. When the concentration is 6.25× 10-6mol/L(0.3mg/L), it can irritate eyes, nose and throat. When the concentration is (6.25-62.5) ×10-5 mol/L (3-30 mg/L), headache and local paralysis of respiratory organs occur. When the ozone concentration is 3.125×10-4 ~10-3 mol/l (15 ~ 60 mg/l), it is harmful to human body.

Extended data:

Symptoms of ozone poisoning: ozone can play the role of disinfection and sterilization, but it will do harm to human body if it exceeds a certain dose. Ozone poisoning, mild respiratory irritation symptoms, such as chest tightness, sore throat and discomfort; In severe cases, bronchitis and pneumonia occur; The most serious result is pulmonary edema, which is life-threatening.

First-aid measures for ozone poisoning: The best way to treat ozone poisoning is to leave the poisoned environment, ventilate, control symptoms in severe cases and avoid severe pulmonary edema.

Nursing knowledge of ozone poisoning: treatment should be carried out according to the principle of irritating gas poisoning, with the focus on preventing and treating pulmonary edema as soon as possible.

Measures to prevent ozone poisoning: reform the technological process, such as adopting automatic welding; The workshop should provide adequate ventilation and local exhaust devices. Strengthen personal protection, such as wearing a gas mask.
