1. Cover the nose and mouth carefully with a mask and fasten it to minimize the gap between the face and the mask;
2. Avoid touching the mask during use-After touching the used mask, for example, to remove the mask, wash your hands with soapy water or alcohol hand sanitizer;
3. After the mask is wet or contaminated with moisture, put on a new clean and dry mask;
4. Do not reuse disposable masks. Disposable masks should be replaced after each use and disposed of immediately after removal.
The specific steps are:
Preliminary: distinguish between positive and negative and up and down
The mask is divided into front and back sides, the upper side and lower side, the front side is darker (outward), and the back side is lighter.
Step 2: Wash your hands
You need to wash your hands before wearing a mask, because the mask is relatively sterile. If your hands are dirty, touch the mask. The dirt on your hands will get on the mask, and the mask will be worn white.
Step 3: Put it on
Make sure that the face of the mask is facing inwards and the metal strip is facing up, and hang a pair of ropes over your ears.
Step four: compaction and stretching
Use both hands to press the metal strips on both sides of the bridge of the nose so that the upper end of the mask is close to the bridge of the nose, and then stretch the mask downwards so that the mask does not leave wrinkles and better cover the nose and mouth.
The correct wearing method can prevent gas from entering and exiting from both ends of the bridge of the nose, thus exerting the filtering and ventilating functions of the mask, protecting yourself and protecting others.
What needs to be expert is that no matter what type of mask is, the protective effect is limited and needs to be replaced regularly, it is best to replace it every 2 to 4 hours.
