Epidemic Prevention Class ｜ How to prevent the risk of air -solution communication in the family

Under the new crown epidemic, home has become one of the effective measures to reduce the flow of personnel and respond to the Omikon virus. Studies have shown that under the conditions such as closed environment, high exposure concentration, long exposure time, the new coronary virus can spread and spread through gas solution and spread the risk of diffusion. Then, as a relatively closed place for the family, once a positive personnel occur, there will be risk of air -soluble gum transmission.

NO.1 What is air -soluble glue

Aerosol (Aerosol) dispersed from a small point of solid or liquid, and the colloid dispersing system formed in the gas medium, also known as the gas dispersing system. The size of gas -soluble gum particles is usually between 0.01 ~ 10 μm, which can be suspended in the air for a long time and migrate. For example, when sneezing indoors, if there is a sunlight into the house, you can see a small droplet that forms floating.

NO.2 Features of gas -soluble gel propagation

1. indoor communication risk is greater than outdoor. Most virus infections occur indoors, of which the proportion of indoor transmission in the family clustering epidemic is greater;

2. Good ventilation can significantly reduce the risk of communication;

3. The closer the distance, the higher the risk of communication;

4. The positive proportion of the environment in the family bathroom is higher;

5. There is a risk of upper and lower dissemination of the same unit in the same building.

NO.3 Family may exist

Qi -soluble gum transmission risk

1. In the case of not wearing a mask, people talk to people, laugh, and pass the risk of mixed dissemination of gas solution and droplets through breathing, coughing, sneezing, etc.

2. When using the toilet toilet flushing, excrement will generate a large amount of droplets and biological gas solution. It splashes to the toilet. It may enter the upper and lower floors of the same unit through the exhaust pipes to cause vertical transmission risk. At the same time, the air solution in the sewage pipe may also enter the same unit up and down floors through the floor drain to cause vertical propagation risks.

3. The smoke exhaust pipes in the kitchen may also cause the risk of vertical transmission of air -soluble on the same unit.

4. If you use a central air conditioner with a backwind, there is a risk of air -solving the risk of spreading to other rooms through the wind.

Measures for preventing air -soluble communication in the family

According to the characteristics of air -soluble dissemination, the area and risk behavior of the risk, the following protection measures should be made in the family:

(1) Symbol area

1. The toilet and shower drainage floor drain should be set up with a water sealing device to replenish the water in time. Water injection more than 2 times a day, at a time of no less than 350ml to prevent the gas solution from spreading through the pipeline of the pipeline. If the floor drain has no water sealing conditions, it should be covered after use, or uses silicone pads, tapes and other materials for blocking. The drainage pipeline of the shampoo and other appliances should be closely connected to the drainage system. If a inserted connection is used, a sealing treatment should be used. When the toilet flushing, cover the toilet cover first, and then flush the water.

2. The ventilation of windows should be strengthened in the bathroom to keep the air flow; if there is no natural ventilation conditions, the exhaust equipment needs to be turned on for ventilation.

(2) Kitchen area

3. When the kitchen uses range hoods and fans, the window should be kept naturally ventilated throughout the process. The drainage pipeline of the washing basin and other appliances should be closely connected to the drainage system.

(3) Cleaning and ventilation

4. Open the window to ventilate regularly, and extend the window opening time according to the climate conditions. In principle, at least 2 times a day, at least 30 minutes each time.

5. If a concentrated air conditioner is used in residential buildings such as apartments, the return wind should be turned off. All the fresh air is taken from the outdoor and runs according to the new style model.

6. The living room is cleaned at least once a day, mainly cleaning, and disinfection if necessary, especially the toilet, toilet circle, door handle, faucet and other high -frequency contact areas or parts.

(4) Personal protection

7. Keep good hygiene habits, wash your hands frequently to avoid contact with your nose and eyes with your hands; cover your mouth or nose with paper towels or elbow clothes when sneezing or coughing.The mouth and nose secretions are wrapped in paper towels and abandoned in the trash can.Final summary

There is a risk of transmission in gas solution

But anti -controlled

Don't panic!
