An Introduction to Chemical Hose
Disposable masks are one of the most economical and practical dust masks on the market. They are accepted by the public because they are cheap and easy to wear. However, when many people wear disposable masks, because they do not know the correct method, the masks do not have a protective effect at all. Here I will introduce the correct wearing method of disposable masks and several points that require special attention when using masks.
1. Disposable masks have white and blue sides, with the white side facing in, the side with the metal strips facing up, and attach the mask horizontally to the mouth and nose of the face, and use both hands to hang the rope on the ears at both ends;
2. Pull up the upper edge strap of the disposable mask, cover the mouth and nose with the mask, and pull the two upper straps behind the ear to fasten to the head, not to the ear;
3. Use both index fingers to press the wire on the nasal root of the disposable mask to make it close to the skin of the nose, and then gradually move the forefinger to both sides. The entire mask is close to the facial skin.
4. After taking off the disposable mask, put it in tape or paper bag and wrap it, then put it in a covered trash can and discard it, and wash your hands in time. Do not reuse the disposable mask.
