What are the options for indoor air disinfection?

Indoor air disinfection selection method:

1. Natural ventilation is the most economical, simple and effective way to keep indoor air fresh and reduce the concentration of bacteria. It can be used with or without people. for the prevention of SARS.

is of great significance.

2. In the presence of respiratory tract.

After infectious people, a single air disinfection method is used, even if all the microorganisms in the air are killed, because the microorganisms that pollute the surface are not killed, the air can soon be polluted again. In this case, a more reasonable method should be to disinfect the surface of the object and disinfect the air at the same time, and peracetic acid can be used.

or disinfectants such as hydrogen peroxide for spraying or fumigation.

3. The air disinfection method when people are in the time can choose a circulating air sterilizer or an air sterilizer such as static electricity.

Carry out continuous dynamic disinfection treatment. When using this air disinfection method, it should be combined with the hygienic cleaning treatment of indoor surfaces or disinfectant to disinfect the contaminated surfaces first to ensure the air disinfection effect.

Choose a fixed irradiation method, or you can choose a mobile one, which can achieve the effect of disinfection. At the same time, it is also necessary to understand the choice of air disinfection machine. There are many options for air disinfection methods, such as natural ventilation is a very common and simple method, and you can also choose the method of disinfectant, or the method of air disinfection machine.

If you want to disinfect indoor air, you can open the windows every day for ventilation to purify the indoor air, or you can use more old-fashioned methods, vinegar fumigation or ultraviolet lamps can kill 90% of the microorganisms in the air in the room.

1: Open windows regularly for ventilation to reduce the density of indoor microorganisms.

2: Purify with an air purifier.

3: Disinfect with disinfectant spray and fumigation.

Ventilation and keeping the room clean: Regularly opening windows for ventilation is an effective way to reduce the density of microorganisms in the room.

Peracetic acid, chlorine dioxide, hydrogen peroxide.

In the case of respiratory infectious diseases, a single air disinfection method can quickly pollute the air again because all the microorganisms in the air are killed, because the microorganisms on the contaminated surface are not killed. In this case, the more reasonable method should be to disinfect the surface of the object and disinfect the air at the same time, and spray or fumigation can be carried out with disinfectants such as peracetic acid or hydrogen peroxide.

Precautions for indoor air disinfection.

1. It is forbidden to use spray disinfection indoors, and the wiping method should be used for disinfection and spillage should be avoided during the disinfection process, and the concentration in the air should not exceed 3 to prevent fire and keep indoor ventilation.

2. Open flames must be prohibited when spraying disinfection methods are used outdoors to prevent excessive local spraying concentration and the risk of burning in case of open flames.

3. It is forbidden to spray alcohol on the body, clothes or masks to prevent the clothing from being burned or caused by static electricity, and the wiping method can be used for disinfection.

4. After use, towels and other cleaning tools should be rinsed with plenty of water and stored tightly or placed in a ventilated place to dry.

Natural ventilation. Natural ventilation of doors and windows can effectively reduce the number of microorganisms in the indoor air, improve the indoor air quality, and adjust the microclimate of the room, which is the simplest and most effective indoor air disinfection method.

There are physical disinfection methods for indoor air disinfection. 1. Opening windows regularly for ventilation not only helps to enhance indoor air circulation, but also reduces or removes indoor pathogens. Of course, the ventilation time can be extended in summer, and the windows should be opened 2 to 3 times in winter, and each time it should not be less than 20 minutes.

Second, the ultraviolet disinfection method, the method is very simple, that is, the object to be disinfected is exposed to strong light. Of course, with the intensity of sunlight, the irradiation time should also be appropriately extended, so that the sterilization effect is better. However, during the exposure process, it is necessary to turn the item over at regular intervals so that all sides of the item can be exposed to sunlight.

Normally, the disinfection effect can be achieved in 4 to 6 hours. In addition, you can also use ultraviolet lamps to irradiate them, which can also have a good disinfection effect on objects. However, before disinfection, the room must be cleaned, and in order to consider the safety of the bedroom, people must leave the room during the irradiation process, and the disinfection time must be more than half an hour.

Chemical disinfection-wipe-to-wipe methodOf course, you can also use chemical solutions to clean contaminated objects, especially floor displays. The fumigation method uses the gas of disinfectant to disinfect, which is mainly suitable for disinfection of the living room and the surface of the living room where the patient has stayed. The spray method begins by filling the container with disinfectant liquid, then spraying the space, and after spraying, the doors and windows are closed for an hour and the person is temporarily removed.

Summary of the knowledge points in the chapters of the licensed pharmacist exam, I wish you an easy way to obtain evidence.

1. Chlorine-containing disinfectant, glutaraldehyde has a large molecular weight, and is liquid at room temperature. 84 disinfectant, disinfectant powder, bleaching powder, bleach, bleaching solution, fast-acting net, Jianzhisu, sodium hypochlorite disinfectant or chlorine-containing effervescent tablets.

2. Commonly used compound preparations based on sodium hypochlorite are mostly liquid disinfectants. Compound preparations based on sodium dichloroisocyanurate or sodium trichloroisocyanurate are mostly powders or tablets.

E, the first floor said, in fact, this is generally not poisoning, but the oral cavity should not be contacted, and glutaraldehyde has a large molecular weight, and the room temperature is liquid, so it is ......Not very good as an air disinfectant!

Generally, it is sprayed with chlorogen and 84 disinfectant: it can also be irradiated with ultraviolet lamps indoors.
