What are the precautions for using UV germicidal lamps?


Ultraviolet germicidal lamp is a very convenient sterilization equipment. It does not use chemicals, nor does it require spraying and other operations. Just turn on the switch to complete disinfection, and the killing efficiency of pathogenic bacteria is very high. However, although it is convenient and safe, there are still some things to pay attention to when using it.

UV TUBE

The first is that when the ultraviolet germicidal lamp is turned on, people cannot be exposed to ultraviolet rays. This germicidal lamp is mainly used indoors, such as wards or laboratories, or production workshops. Require personnel to leave the room before opening, and it is best to keep the door closed after opening for sufficient opening time. The general power germicidal lamp needs to be turned on for half an hour to achieve the purpose of thorough disinfection, and because a small amount of ozone will be generated while irradiating, it is necessary to wait another twenty minutes to half an hour after the germicidal lamp is turned off at the time of arrival. It takes time for the ozone in the room to be completely decomposed before people can enter the room. Places like laboratories need to be disinfected every day, so it is best to arrange experiments and disinfection plans in advance to prevent work delays due to long waiting times.


Due to its own principle, the ultraviolet germicidal lamp will contain a small amount of mercury in the lamp tube. Under normal use, the mercury is enclosed in the lamp tube, which is not harmful to people, but if the lamp tube is accidentally broken, the mercury in it will spill into the room, and the mercury vapor generated after volatilization has a serious toxic effect on people. Therefore, you must be careful when installing and wiping the lamp tube, and once it is broken, you must handle it carefully, and try to recover the sprinkled mercury particles. It can also be treated with sulphur powder, as sulphur can react with mercury to form mercury sulphide.


Generally speaking, the safety of ultraviolet germicidal lamps is still very high. As long as you are careful not to be exposed to the lamp when it is turned on and just turned off, and at the same time be careful not to break the lamp tube, then it can be used with confidence.
