Cars are not absolutely safe! How to do well the epidemic prevention work of private cars?

I wonder how many car owners will pay attention to the health and epidemic prevention in the car?

I heard from some friends that when I really couldn't stay at home, I went downstairs for two laps without wearing a mask!

There are also friends who come back from afar, saying that as long as you don't open the window, the virus can't get in and the mask doesn't cost money. ......

Don't think that the car is a safe haven as soon as the door is closed!

Tell everyone how to do a good job of epidemic prevention in the car in one minute.

Although the tightness has become a major standard to measure the design of new cars, it is impossible to achieve absolute tightness no matter how strict it is, and the air outside the car will still leak into the car from the air conditioning duct. Many people think that turning on the internal circulation mode can stop harmful gases and even viruses, but this is actually a misunderstanding. The internal circulation of the vehicle only blocks the outside air from entering the air conditioning pipeline through a flap, but the wind will destroy the seal of the flap when the vehicle is driving, and the outside air will still enter the compartment.

As can be seen from the structural diagram, the internal and external circulating damper is located at the outermost end of the air conditioning pipeline, and the rotating shaft of the damper is driven by a motor. When the flap is in the black position, the outside air can directly enter the pipeline, which is external circulation; When the flap is located at the red mark, the pipeline is communicated with the air inlet in the car and is in an internal circulation state.

The walls will be ventilated, not to mention plastic plates. High-speed wind will enlarge the gap of the flap. However, judging from the influence of internal and external circulation on PM2.5 value, the barrier rate of internal circulation is indeed slightly better than that of external circulation, but it is not conducive to eliminating harmful gases in the car.

First, you must also wear a mask in the car.

1. Be sure to wear a mask when you are used to opening the window or need to get on and off the bus many times.

2. Don't take off the mask casually in the car, and don't use it repeatedly.

3. If the old mask is removed, it must be replaced with a new mask in time.

4. If the environment inside the car is sanitary, you must take off the mask outdoors before getting on the bus outdoors, and never bring the used mask into the car.

5. Wipe the steering wheel and internal parts with alcohol regularly to achieve effective disinfection effect.

Second, choose an air-conditioning filter element with antiviral effect.

Air-conditioning filter element is the umbrella of air in the car, and it is also an important part of epidemic prevention in the car. You can replace the air conditioning filter element with virus suppression effect.

Third, disinfect the whole vehicle in time.

Vehicles with high frequency of use and vehicles that have transported patients are recommended to be disinfected in time. You can spray the car with disinfectant to remove germs.

For example, use diluted 84 disinfectant (available 1: 200), 75% alcohol or lysol to wipe and spray.

Fourth, pay attention to ventilation.

1, open the window for ventilation. Lower the window a few centimeters, leaving a gap. Vehicles with skylights can also be ventilated with skylights. It is recommended to open the skylight for ventilation at regular intervals.

2. Ventilation with air conditioner. It is not enough to turn on the air conditioner to the automatic gear. The air in the car is not circulating, which is very harmful to the health in the long run. The correct way is to start the engine in the car, open the window for ventilation during the hot car, adjust the air conditioner to the external circulation, adjust the air inside the car, then slowly start the car, close the window and adjust the air conditioner to the internal circulation.

Key points: sit around, touch less, wear gloves and wash your hands frequently.

Chief expert of disinfection of China CDC and expert of disinfection center of environmental institute suggested? When taking public transport such as cars, trains, planes, ships, etc., you should sit as far away as possible or separately, and keep your distance from strangers.

The risk of taxis, online car rides and other means of transportation is lower than that of trains and planes. Passengers are advised to open the door for ventilation before riding, and disinfect the seat and hand contact parts with disinfectant paper towels.

What if it is inconvenient to wash your hands outside? Can disinfection wipes and sprays play a disinfection role?

It is recommended to wear gloves to reduce contact with the outside world. You don't need professional rubber gloves, just wear ordinary gloves, and pay attention to washing frequently after you go home.

No matter what kind of transportation you take, you can wash your hands at any time after the trip. You can carry a disinfectant paper towel or hand sanitizer with you without washing, and wipe the palm, back of hand, fingers, fingertips, thumb and other parts. If you are allergic to alcohol, you can use alcohol-free hand disinfectant.

Strong protection, no need to panic, the epidemic can be prevented!
