Is ozone sterilizer harmful to people?

Now ozone is not used for disinfection, because there are other disinfection methods, ozone disinfection is very harmful to human health, which will be introduced in detail below. As ozone is a kind of enhancer and bactericide, it can enter the germ cell, destroy its tissue structure and oxidase, and play a bactericidal role. When the effect is related to ozone concentration and action time, it is harmless to human body and can purify the air. Only staying in the environment with excessive ozone concentration for a long time will have an impact on people's respiratory system, but ozone has active characteristics and poor stability, and will be reduced to oxygen in less than 2 minutes when it meets moisture in the air.

Ultraviolet disinfection ultraviolet lamp tube will produce two different kinds of light when it works, one is visible light, which is the blue light we see, and the other is invisible light, which mainly refers to two different wavelengths of light.

The disadvantage of high temperature disinfection is also fatal. Excessive power can easily lead to uneven temperature, and high temperature can easily damage and deform the cavity and the heated object. To sum up, the hidden danger of high temperature is still relatively large, especially when the disinfection cabinet is installed under the cooker, high-temperature products such as ovens and high-temperature disinfection cabinets are very dangerous-star disinfection standard for edible fungi pressure cookers: it can kill representative strains such as Escherichia coli.

Extended data

Matters needing attention

1, ozone is irritating to human respiratory mucosa. When the ozone concentration in the air reaches 0. 15ppm, it can be smelled. According to international standards, it can cause discomfort such as dry mouth when it reaches 0.5- 1ppm; Reaching 1-4ppm can cause cough; Up to 4- 10ppm can cause a strong cough. Therefore, ozone disinfection of air must be carried out without people, and it will take at least 30 minutes to enter after disinfection.

2. Ozone is a strong oxidant, which will damage many kinds of articles. The higher the concentration, the more serious the damage to the goods, which can cause green rust spots on copper sheets, aging of rubber, discoloration and reduced elasticity, leading to brittleness and fracture, and bleaching and fading of fabrics.
