3 In the daily use of ultraviolet lamps for sterilization work, the What do we need to pay attention to?
1、Applicable area and objects. Before using the UV lamp for disinfection, be sure to read the product manual carefully to see the applicable area and objects of the UV lamp, otherwise, it will lead to some parts of the room are not disinfected, therefore reducing the effectiveness of the use.
It should also be noted that some people want to disinfect their masks with UV lamps so that the masks can be reused. In fact, UV lamps do have a disinfecting effect on masks, but it is not recommended that you do so. Many masks (especially N95 masks) are now made of polypropylene melt-blown material, which is very sensitive to UV light and has poor aging resistance. After receiving ultraviolet radiation, the internal structure of the mask will be damaged, i.e. oxidative degradation, and the filtration performance will be significantly reduced.
2, irradiation distance. When using the UV lamp, we should also pay attention to the irradiation distance, that is, the distance from the lamp to the object to be illuminated. Generally speaking, the appropriate distance of the UV lamp is between 1-2 meters, so when using it, it is best to place the UV lamp to the center of the space. Since the disinfection feature of UV lamps is coverage, that is, the place covered by the light will be disinfected, so when using to minimize the blockage of light, some items (such as quilts, etc.) can be spread out to irradiate disinfection.
3, no one is in the room when you use it, open the window for ventilation after use. Although the UV lamp Although the disinfection effect is good, if used improperly will cause damage to humans, The first thing to do is to make sure no one is in the room. Therefore, the first thing to do is to make sure that no one is in the room when you use it and Close the windows and doors, and after enough irradiation time (depending on the intensity of the UV lamp used) (depending on the intensity of the use of UV lamps and different, the specific need to refer to the product instructions), the Open the windows and ventilate for a period of time before someone enters. The reason for this is that the UV lamp will produce ozone in the process of use. Ozone will be generated during the use of UV lamps, and the high concentration of ozone will cause dizziness, nausea, and other symptoms, and even cause respiratory pathology. And long-term wrong use of UV lamps can be harmful to the eyes, inducing conjunctival and corneal diseases, and in serious cases, even affecting vision. Not only that, if long-term Is irradiated to the skin for a long time, the light will appear red, swollen, itchy and other symptoms, and the heavy In serious cases, it can even cause skin cancer.
