    How to Put on a Medical Mask

Medical masks are mainly used by health care professionals to protect themselves and others. The masks can prevent the spread of infectious diseases. During a bad disease outbreak, that the public wear masks to protect themselves is also recommended. Here are some steps to wearing a mask properly.

Clean your hands. Before touching a clean medical mask, wash your hands thoroughly with both soap and water. Once you've applied soap, you should rub your hands together to wash them for at least 20 seconds. Always use a clean paper towel to dry your hands. 1.

Check the medical mask for imperfections. Once you've taken a new medical mask from the box, check it to ensure it doesn't contain any imperfections, holes or tears in the material. 2..

Orient(确定方向) the top of the mask properly. In order for the mask to fit as close to your skin as possible, the top portion of the mask will have a bendable, but stiff edge that can be shaped around your nose. Ensure this bendable side is facing upwards before applying the mask to your face.

Pick up this type of mask by the loops(环), put one loop around one ear and then put the other loop around your other ear. If it is a mask with ties, pick up the mask by the upper ties, place the ties around the back of your head and attach them together with a bow.
