What does a UV light that kills germs do?
UV disinfection lamps employ ultraviolet light to destroy bacteria, coronaviruses, fungus, rickettsiae, and chlamydia, among other things. UV radiation may be used to disinfect any surfaces, water, or air that have been affected by the aforementioned pathogens. It should only be operated and utilized by specialists, and it is not appropriate for public usage since it is sensitive to several variables.
UV harm to people's bodies
Infrared light from mercury lamps, which generates high amounts of UV radiation and is easily harmful to the human body if not shielded, is used by UVC lamps to perform germicidal disinfection.
These lights can cause redness, swelling, itching, and flaking when exposed skin is subjected to them. When the human eye is exposed to UV light, the cornea directly absorbs the UV light, which causes a significant amount of corneal epithelium to peel off. This condition, known medically as electro-optical ophthalmia, causes redness and swelling, tearing, the inability to open the eyes, dryness, and other symptoms.
UV light use and safety measures
UV disinfection lamps must be operated inside and unattended, and the room must be sealed off to non-disinfection staff while disinfection is taking place.
There has to be a sign outside the facility alerting people not to enter and remain when the UV lamp is being used to disinfect.
Prior to moving the UVC lamp, it must cool down and be timed from 5-7 minutes after the lamp is turned on.
After disinfection, the UV lamp must be turned off, and the windows and doors must be opened to let in enough ventilation before entering.
To prevent harm from direct UV rays, disinfection staff should wear personal protection.
