What are the pros and cons of different sterilization methods: alcohol, 84 disinfectant, UV lamp (Using an UVC meter to detect its intensity).

Recently, the development of the epidemic has finally stabilized and many small partners have begun to return to work one after another. Although it has not yet entered the full resumption of work, we should still take care to the sterilization.  During the epidemic, various disinfection methods were turned over by everyone. 84 disinfectant, alcohol, ultraviolet germicidal lamp and even smoked white vinegar were used for disinfection. But many people do have some negligence in use. Especially when using an ultraviolet germicidal lamp, it is necessary to use an UVC meter to detect whether the ultraviolet germicidal lamp can achieve the disinfection effect.

UVC energy meter

1. Alcohol

Many people usually use medical alcohol to spray directly on their bodies when they use alcohol. This is true in the car and at home. Although 75% of medical alcohol can achieve the purpose of killing viruses, spraying alcohol on such a large area is actually very dangerous. Whether at home or in a car, if there is an open flame, such as the use of lighters, smoking, etc., it is easy to cause a fire.

2. 84 disinfectant

There are two main components of the common 84 disinfectant, one is sodium hypochlorite and the other is sodium chloride. Although the disinfectant can also achieve the purpose of disinfection, these two substances are corrosive. For example, when disinfecting a car, these two substances have a certain degree of corrosiveness to the tires, bare metal parts and interior parts of the car. 

3. UV germicidal lamp

It was mentioned in the "Fourth Edition of the New Coronavirus Infected Pneumonia Diagnosis and Treatment Program (Trial)" published by the National Health Commission and the State Administration of Traditional Chinese Medicine. % Ethanol, chlorine-containing disinfectants, peracetic acid, chloroform and other lipid solvents can effectively inactivate viruses. In other words, ultraviolet germicidal lamps are not only effective in sterilization and disinfection, but also effective in the face of new coronaviruses. At that time, the prerequisite for killing the new coronavirus was to detect and ensure that the anti-virus effect of the ultraviolet lamp was qualified. An UVC meter is usually recommended.
       Ultraviolet germicidal lamp disinfection has the advantages of colorless, odorless and chemical substances left behind. But if there are no protective measures in use, it will still cause great harm to the human body. As for how much damage is caused, it also depends on the power of the UV lamp and the exposure time. The UVC meter can accurately detect the specific power of the ultraviolet lamp.
       In fact, the use of ultraviolet germicidal lamps has a long history. For hospitals, the use of ultraviolet germicidal lamps to sterilize the air has been in the hospital for decades. Of course, you need to regularly use an UVC meter to detect its intensity to ensure the efficacy of the ultraviolet lamp. Although the ultraviolet lamp is very harmful to the human body, there is no problem if it is only exposed to ultraviolet rays. Its penetration ability is relatively weak, the injury will be reduced when the glass is separated.
