What are the hazards of UV lamps? Precautions for the use of ultraviolet disinfection lamps
I believe that everyone is familiar with UV lamps. This was originally a medical and sterilization appliance, but now it is gradually being used in various public places and homes. Among them, unscrupulous merchants do not clearly show the harm of UV disinfection lamps for profit. As a result, most consumers now have no idea about the hazards of ultraviolet disinfection lamps. So what are the hazards of UV lamps? What are the precautions for the use of ultraviolet disinfection lamps? Next, BENWEI will explain it for you, let's take a look.
What are the hazards of UV lamps?
1. Since ultraviolet rays can kill cells, be careful not to directly irradiate human skin, especially human eyes, when sterilizing ultraviolet rays. Do not look directly at the tube when the ultraviolet germicidal lamp is on. Short-wave ultraviolet rays do not pass through ordinary glass. Wear glasses to avoid eye injury. If the eye is accidentally injured, it is generally not a major problem, just like being burned by the sun, serious eye drops can be used to help recover.
2. The ultraviolet lamp uses the ultraviolet light emitted by the mercury lamp to achieve the sterilization and disinfection function. The ultraviolet energy radiated by it is relatively large. If there is no protective measure, it is easy to cause great harm to the human body. If the bare skin is irradiated by this type of ultraviolet light, redness, swelling, itching, and scaling will occur in the lighter ones; the more severe ones can even cause cancer and skin tumors. At the same time, it is also an invisible killer of the eyes. It can cause inflammation of the conjunctiva and cornea, and long-term exposure may cause cataracts. For some small ultraviolet lamps used in restaurants and homes to kill mosquitoes, their light-emitting principles are different. Consumers No need to worry.
3. If there are severe patients such as leukemia in the home, a relatively sterile environment is needed to purchase ultraviolet lamps. The ultraviolet lamps must not be used for ordinary home lighting. When it is necessary to use ultraviolet light for disinfection, it is also necessary to avoid direct contact between skin and eyes with ultraviolet radiation. In public places, if you encounter ultraviolet disinfection, you should avoid it in time, especially to prevent children with thin skin stratum corneum from entering the ultraviolet operating area by mistake.
Precautions for the use of ultraviolet disinfection lamps
1. The role, hazards and methods of use of ultraviolet disinfection lamps
The ultraviolet disinfection lamp should be used carefully. When it is used for air disinfection, the doors and windows should be closed. The time is 5-7 minutes after the light is on. The disinfection time should not be less than 60 minutes each time. During the irradiation of the ultraviolet disinfection lamp, people are prohibited from entering the room. The ultraviolet disinfection lamp should be stopped first, especially young unmarried ladies should keep this in mind.
2. Effective distance
When disinfecting items with ultraviolet disinfection lamps, spread or hang the items to expand the irradiation surface. The effective distance is one meter, and the irradiation is about 30 minutes.
3. Extend the time when the humidity is high
When using ultraviolet disinfection lamps, the environment should be kept clean. There should be no dust and water mist in the air. When the indoor temperature is lower than 20 degrees Celsius or the relative humidity exceeds 50%, the irradiation time should be extended. After scrubbing the floor, wait until the floor is dry before disinfecting with ultraviolet light.
4. Keep it clean
The surface of the ultraviolet disinfection lamp tube should be kept clean and free of dust. Wipe it with a 95% ethanol cotton ball once a week, and it is best to keep a record.
5. Protect your eyes
Ultraviolet rays have certain damage to human skin and mucous membranes. When using ultraviolet disinfection lamps, pay attention to protection. The eyes must not look directly at the ultraviolet light source, otherwise the eyes will be harmed.
The above is the knowledge of the hazards of UV lamps and the precautions for the use of UV disinfection lamps. The content is for your reference only, and I hope it can be helpful to everyone.
