How to Drive a Car Safely Without Getting Caught by COVID-19?

by copytalkie

Scientists have studied how to travel in a vehicle without catching COVID-19 and what methods are effective. Accordingly, opening all the windows in the vehicle significantly reduced the risk of particles reaching the other person.

Over a year in our lives new type of coronavirus outbreakcontinues to spread around the world. People who want to be protected from the virus want to minimize the risk by taking measures such as masks, hygiene and social distance. However, instead of public transport by special means traveling is also one of the factors that reduce the possibility of getting the virus.

So what if you are traveling with others rather than alone in a private vehicle? Physicist from the University of Massachusetts Amherst Varghese Mathai and Brown University researchers modeled how particles can move inside vehicles with different ventilation levels.

Which windows should be opened?

Earlier this month Science Advances The most effective way to remove potentially virus-laden particles from a car, according to simulations published in open all windows. The tiny particles inhaled by a person with all windows closed 8% to 10% If the other person in the vehicle can be reached and all four windows are open, this number 0.2% to 2%It was observed that it fell up to.

Of course, opening all windows on the cold winter days is not a logical option, so the researchers tried different alternatives and made some suggestions. Accordingly, if two windows are to be opened, driver and passenger seats opposite it was recommended to open the windows.

The simulated vehicle was assumed to have a driver in the left front seat and a passenger in the right rear seat. At this point, although a passenger intuitively chooses to open the window closest to him when they get in the car of the driver (front right window) and passenger (left rear window) Opening the windows opposite showed better results in the model.

The most effective method of protection is wearing a mask:

In a moving vehicle, fresh air typically flows through the rear window and out the windshield, Mathai said. In such a situation, opening the windows opposite the passengers not only provides an entry and exit point for particles, but also a stream of air separating the passenger from the driver creates.

On the other hand, if you are traveling in a car with someone else, Wearing mask and lowering the windows at least half might be a good option. Regardless, Mathai said opening the windows was not a perfect way to avoid the risk of contamination, and leaving them ajar would not work well.

Between driver and passenger plastic barriers can also help stop particles. While these potential barriers were not taken into account in the simulation, Mathai stated that barriers help prevent any particle penetration, while at the same time, a good ventilation system can reduce the risk to much lower levels.
