Beijing Chewen Powder uses alcohol and 84 disinfectant, so we must pay attention to these safety issues.

Bian Xiao published a tip about car disinfection before. Because of novel coronavirus's in vitro activity, Guangzhou CDC found virus nucleic acid on the doorknob of a patient's house, so it is particularly important for household and car disinfection. ?

There are two main disinfection methods we can use, 75% medical alcohol is always used and 84 disinfectant is used. These two methods can kill viruses well, and they are relatively easy to produce, relatively cheap and simple to use. They have become widely used disinfectants and are used by many people at home. ?

However, if alcohol and 84 disinfectant are used improperly, it is very likely to cause safety accidents. For example, using medical alcohol may cause fire, and 84 disinfectant may cause human poisoning. Therefore, Bian Xiao combined the nature of alcohol and 84 disinfectant to talk about how to carry out disinfection work safely. ?

Pay attention to fire prevention when using medical alcohol?

First of all, we should know that medical alcohol is a mixed solution of ethanol and water, in which the concentration of ethanol is 75%. Medical practice has proved that 75% medical alcohol has the best disinfection effect, which can kill a variety of bacteria and viruses, as well as novel coronavirus. ?

In addition to disinfection, ethanol is mainly used as fuel in industry. For example, ethanol gasoline, as its name implies, is a mixture of ethanol and gasoline as automobile fuel, which means that gasoline and ethanol are highly volatile and easy to burn. Although the medical alcohol used in the disinfection process is not pure ethanol, its concentration has reached 75%, and it is also extremely flammable. When using alcohol, be sure to stay away from the fire source to prevent accidental ignition of alcohol from causing fire accidents. ?

Medical alcohol should not only prevent direct contact with fire sources, but also pay attention to the combustion and explosion caused by alcohol vapor. Therefore, when you use medical alcohol for spray disinfection, don't spray a lot in a closed space, such as a room with closed doors and windows. Pay attention to open the window for ventilation during disinfection, and do not have open flames. The same is true for disinfecting cars. It is very important to open the window to keep the air circulating. ?

Use 84 disinfectant to prevent poisoning?

We should also know that 84 disinfectant is a mixed solution of sodium hypochlorite and sodium chloride. Sodium hypochlorite can play an effective disinfection role, while sodium chloride is a by-product of production and does not play a disinfection role. Under the chemical reaction, 84 disinfectant can effectively kill bacteria and viruses, and it is also effective for novel coronavirus. ?

But it can not only kill bacteria and viruses, but also has strong corrosiveness to human cells. Therefore, when using 84 disinfectant, it should be diluted according to the use requirements and protected with gloves to avoid physical contact and inhalation. ?

So when you use 84 disinfectant for spray disinfection, don't spray a lot in a closed space, such as a room with closed doors and windows. Pay attention to window ventilation when disinfecting, as well as disinfecting your car. It is very important to open the window for ventilation and keep the air circulating. ?
