What can't be irradiated with ultraviolet disinfection lamp?

Ultraviolet disinfection lamp can not directly irradiate human skin and eyes, otherwise it will easily cause electro-optic ophthalmia and skin damage. Because short-wave ultraviolet rays can't penetrate glass, wearing glasses can avoid causing too much damage. Try to avoid the presence of people when carrying out irradiation disinfection.

note:

Ultraviolet disinfection method

1, air disinfection: Please close the doors and windows when using, keep the room clean and dry, and start counting after turning on the light for 5-7 minutes. The effective distance is less than 2 meters, and the disinfection time is 30-40 minutes each time.

If it needs to be turned on again after turning off the lights, it should be turned on intermittently for 3-4 minutes; No one is allowed to enter the room during the ultraviolet lamp irradiation, and ozone will be generated during ultraviolet disinfection. After irradiation, windows should be opened for ventilation. When you need to enter, you should turn off the ultraviolet disinfection lamp first.

2. Disinfection of the surface of the article: spread or hang the article so that it is fully exposed to direct radiation, and ultraviolet rays cannot penetrate the object; When the surface of the object is disinfected, the distance between the lamp tube and the polluted surface should not exceed 1m, and the irradiation time should not be less than 30min when the ultraviolet radiation intensity of the lamp tube meets the requirements. High-intensity and low-ozone ultraviolet germicidal lamp is irradiated for 30-60 minutes within an effective distance.
