To protect the public, many companies have been expanded to operate by February 10.

In addition to going out and washing your hands. It also pays attention to ventilation. Perhaps everyone is trying to find a way to buy a mask.

However, since masks have become a scarce resource. Those affected areas have been given priority. So, when face masks are lacking, how to take protective measures on the way to work?

Coronavirus Protection: How to store used N95?

Hold the mask strap with one hand, remove the mask. And do not put the mask in and out. After removing, you can hang it in a dry, well-ventilated place, or place it in a clear sealed bag.

However, if the mask is damaged or dirty, and the breathing resistance becomes larger, change it over time.

Can surgical masks be used repeatedly?

In fact, surgical masks are disposable masks, which usually change every 4 hours. Re-use is not really recommended for everyone.

However, due to special circumstances. The N95 mask and the medical-surgical mask are still in “tight balance,” and resuming work may take some time.

How to use mask scientifically and economically has become a problem for many people.

Zhong Nanshan said: This usually changes every 4 hours, but you don’t need to change it every time you wear it. You do not need to change it after eating or doing other things. Clean cell bags, etc.), you can continue to use, provided it uses the mask itself. However, to reduce the risk of infection, the masks that go to the hospital should be discarded. For now, it is appropriate to wear a mask at the source of this outbreak. Also, in densely populated areas, even if it is not the cause of the outbreak, you should wear a mask.

Does cooking mask work?

In addition, “steam” and “cooking” appear on the network to “disinfect” the mask. This method is extremely unwanted.

Its method is to dry it naturally or to ignite with UV light for half an hour.
