Guizhou dispatched helicopters to carry out aerial killing operations. How can aerial killing be carried out?

aerial disinfection needs to be carried out when no one is around, so it is necessary to issue relevant notices in advance to let residents close their doors and windows and not stay in the aerial disinfection area.

as we all know, the disinfectant tank of helicopter contains a large amount of chemical disinfectant, especially 1 ton disinfectant. When spraying from the air, the concentration of disinfectant in the air will be sharply increased, and the setting of the disinfectant tank can make the disinfectant stay in the air for a longer time, so that the chemical disinfectant in the air can more effectively pounce on the germs in the air.

However, we also need to be clear that these chemical disinfectants can kill bacteria, and also have an impact on our bodies, causing damage to our skin, respiratory tract and so on.

Therefore, when the operation is in progress, there should be no one outside, and people indoors should also take precautions and close the doors and windows. And you need to kill your homework in the air for a while before you can go out.

In fact, after the outbreak of COVID-19, many communities built their own disinfection channels, so that residents and visitors need to pass through the disinfection channels when they go in and out. Many netizens say this is? Hard core protection? Can improve the safety of residents in the community.

However, most disinfection passages in the residential area use 84 disinfectant as disinfection materials. When the concentration is not enough, it is impossible to kill the virus. When the concentration is too high, there is no guarantee that it will not cause harm to human body. Especially a semi-closed disinfection channel, which is easy to cause cross infection?

Therefore, after the news media reported the relevant disinfection channels, the leading group (headquarters) for handling the pneumonia epidemic situation infected by novel coronavirus in Jinan issued a notice prohibiting the establishment of disinfection channels in the community, and other cities began to respond.

At present, there is no chemical disinfectant used for spray disinfection of human body, so care must be taken when spraying with disinfectant.
