Students in elementary and middle schools in most parts of Canada have started to go to school. This is the first time students have stepped onto campus since the pneumonia epidemic has raged in half a year. However, the students and teachers came back wearing masks. What kind of mask to wear, how to wear a mask, and how long a mask can last have become the concerns of parents of students with underage children.
As the new crown pneumonia epidemic continues to spread, masks have become a mandatory public health necessity in many parts of the world. Due to the dwindling supply of medical surgical masks and N95 masks (they are being properly transferred to medical care facilities), the general public is often urged to cover their mouth and nose with anything that can be used when going out to public places. Ideally, self-made masks should have two to three layers, but in the absence of any better options, health departments around the world propose to use headscarves, scarves, or neck sleeves as substitutes for masks. Some experts agreed: "Any mask or covering is better than nothing."
The medical standard protective masks have a life span, and the masks are dedicated for special use and cannot be used interchangeably.
Medical standard protective masks cannot be cleaned. Spraying disinfectants, including medical alcohol, will reduce the protection efficiency. Therefore, it is not appropriate to use alcohol spray to disinfect masks, nor to use heating and other methods for disinfection; cotton masks can be cleaned and disinfected, and other non-medical masks are handled according to the instructions.
Hold the protective mask with one hand, with the nose clip side facing away. Cover the nose, mouth and chin with the protective mask, and the nose clip should be close to the face upward. Use the other hand to pull the lower strap over the top of the head and place it under the ears behind the neck.
