After UV irradiation disinfection, it is generally recommended to enter the room for about 30 minutes. The damage of ultraviolet rays to the human body is mainly caused by direct exposure to the eyes and exposed skin, causing ophthalmia and dermatitis. Therefore, in principle, ultraviolet irradiation disinfection, as long as the germicidal uvc light is stopped, personnel can enter the room.
However, because ultraviolet rays are a type of electromagnetic waves and contain high energy, ultraviolet rays irradiate the air to completely kill pathogenic microorganisms in the air, and at the same time decompose the oxygen in the air to produce ozone, which may cause damage to the human body. Adverse effects, so it is recommended to enter the room about 30 minutes after ultraviolet irradiation disinfection.
Ultraviolet disinfection is a commonly used disinfection method in hospitals and homes. Therefore, mastering the correct operation method of ultraviolet disinfection can not only achieve the effect of disinfection and sterilization, but also reduce some unnecessary damage.
