As we all know, the spread of the epidemic has repeatedly delayed the date of returning to work, but with the passage of time, the tide of rework will still come as scheduled. At this time, in order to avoid crowd gathering, returning by car will surely become the first choice for most people. So, as a private car user, how to prevent novel coronavirus on this return trip?
1. Do private cars need disinfection?
The Temporary Guide for Preventing Private Cars from Infecting novel coronavirus issued by China CDC points out that under normal circumstances, private cars do not need to be disinfected, and they should be ventilated in the open air. When opening windows for ventilation in winter, we should pay attention to the cold caused by the large temperature difference between inside and outside the car. In a closed environment such as an underground parking lot, it is recommended to close the windows and turn on the internal circulation mode of the air conditioner for ventilation.
As pointed out in the guide, because private cars are a relatively closed environment, viruses are not easy to enter the car except by opening the window for ventilation, otherwise the air entering the car through the air conditioning outlet must pass through the air conditioning filter. As we all know, viruses don't live long in the air. In an open place, with the flow and renewal of air, it is not conducive to the breeding and accumulation of viruses, thus preventing viruses from reaching a certain concentration and making people sick; On the contrary, in a closed environment, the air is not circulating, and it is easy to accumulate viruses. At this time, it is very important to open the internal circulation and not to have too much contact with the air outside the car. Therefore, the biggest role of ventilation is to keep the air in the car fresh and clean, and don't let the occupants in the car be in a space that is easy to get sick.
Does this mean that you don't need any disinfection to drive out?
No, drivers and passengers may have viruses on their clothes or hands after returning from public places, and they will also bring viruses to the surfaces of these things after contacting the items in the car, thus causing drivers and passengers to be infected during driving. At this time, a certain degree of disinfection is necessary.
It is also known from the guide that drivers and passengers had better use hand disinfectant for hand hygiene after getting on the bus. Effective disinfectants such as iodophor, chlorine-containing disinfectant, hydrogen peroxide disinfectant or quick-drying hand disinfectant can be selected for wiping disinfection. When relatives and friends ride together, it is necessary to disinfect their hands and skin, and it is also necessary to disinfect related items in the car after use. At the same time, qualified car owners can replace air-conditioning filter elements with better protective effect and virus suppression effect for their private cars in time.
Second, what should I pay attention to when driving?
1, also need to keep ventilation, the reason is the same. When driving in an open place or an open road, properly open the window or skylight for ventilation; However, in closed underground parking lots and other places, or in residential areas and commercial areas where traffic jams and crowds are highly concentrated, it is necessary to close the windows and skylights and open the internal circulation of air conditioners to avoid air pollution in the car.
2. Many people must wear masks when riding, just like wearing masks in public places. Masks can effectively avoid cross-infection. Drivers can wear masks in most cases when driving alone, but it is still recommended to wear masks when they need to pass through crowded places.
3. Keep masks and disinfection supplies on the car so that people can put on masks in time and disinfect the inner surface of the car in time.
During the epidemic, refusing to lend private cars is also one of the ways to prevent their vehicles from being infected with too many viruses.
3. What should I do if I have carried someone with suspicious symptoms?
This is also mentioned in the guide:
1. There are suspicious patients among drivers and passengers. All passengers in the car must wear medical surgical masks that meet the specifications. Colleagues should try their best to avoid the spread of virus caused by the spray and communication of droplets, and don't eat or drink in the car. At the same time, keep a certain distance from the passengers in the car, turn off the internal circulation function of the air conditioner, and open the window for ventilation in time when conditions permit (that is, pass through an open place and clear the road, etc.). ) Avoid viruses in the air inside the car.
2. After the suspicious patient gets off the bus, ventilate the whole car in an open place and disinfect any items (such as seats, door handles, steering wheels, windows, buttons, etc.). ) Suspicious patients may be exposed in the car.
4. What should I do if I have carried novel coronavirus patients?
1. The same protective measures should be taken in the car. People in the car should keep their distance from the patient and avoid any contact.
2. After the patient gets off the bus, the private car should be disinfected in time. When you don't know how to disinfect, you can go to a professional in the local disease control agency or a qualified third party to operate. Do not use the vehicle before it is disinfected.
3. Passengers with patients need to undergo 14 days of medical observation according to the requirements of local disease control institutions.
therefore
Although private car travel is relatively safer than public transportation, the premise is to do all kinds of protection and disinfection measures. Facing the epidemic, we are facing a wave of rework. I hope everyone will cheer up, remember to wear masks when going out, go to crowded places less, do disinfection protection before using the car, wash their hands frequently and maintain good personal hygiene. I believe in the country, let's fight against the epidemic together!
Finally, I wish you all a happy Spring Festival and good health!
