Ultraviolet light is an important physical disinfection method for clinical disinfection. The main equipment for disinfection is the ultraviolet lamp, which is mainly used for disinfection by direct irradiation of the object surface. Disinfection is characterized by the irradiated parts can be disinfected, but no irradiated parts, can not play a disinfection role. Therefore, when using UV disinfection, the UV lamp must be placed in the location where the disinfected part can be irradiated, or the location where the largest area can be irradiated. If you want to use UV lamps for irradiation, try to close the room airtight, of course, when using UV radiation, people must leave the room. Because the ultraviolet ray on the one hand can kill poison sterilization, but also on the skin, eyes can also produce harm. So when using UV lamps, personnel must leave the room. UV disinfection effect lies in the duration. If the exposure time of the UV lamp is too short, it will not play a role in killing and sterilizing. Therefore, it must be irradiated according to the specified time. After the irradiation, the first thing is to ventilate the room to reduce the ozone stimulation caused by the UV lamp.
