What are the precautions for using disposable medical masks

Please note that there are many things to pay attention to when wearing disposable medical masks. The first is that these masks cannot be reused. This is strictly prohibited. Not only that, the mask generally needs to be replaced after wearing it for eight hours at most. Also, when using a mask, be careful not to swap the two sides. This is very dangerous. You should know that there are bacteria on the outside of the mask, and it is very unsafe to wear them alternately. Also, when you are not wearing it, make sure to keep the clean side inside and put it in an envelope.

1. If the mask is wetted by exhaled hot air or saliva, its effect in blocking germs will be greatly reduced. Therefore, it is best to have a few extra masks ready for replacement.

2. If you are in a high-risk place such as a hospital, no matter how long you use the mask, once you take it off, do not use it again to avoid contamination from touching the mask with your hands.

3. When wearing or removing a mask, your hands may come into contact with germs attached to the surface of the mask. To reduce the chance of transmission through contact, special attention should be paid to cleaning and disinfection of your hands.

Also, you should carry a few extra masks with you at all times so that you can use them interchangeably. Another thing to note is that if you take off your mask in a place like a hospital, you must throw it away and cannot use it again, because places like hospitals may be contaminated with bacteria, viruses, etc., so you must be vigilant in advance.
