There are many types of masks, and different types of dust masks are worn differently. Mastering the correct way of wearing masks can more effectively prevent dust and other fine particles from harming the human respiratory tract.
1. The mask does not fit the face
- The fogging of the glasses after wearing the mask indicates that the face of the mask is not close to the face, and the exhaled gas ran to the glasses.
- There is a gap between the mask and the face. When breathing, the airflow will flow to the gap, reducing the filtering effect of the mask.
Correct practice: Press your nose when wearing a mask, and press it firmly against your chin. The stricter the better.
2. Wear a mask regardless of positive or negative
- Masks with white faces facing out are typical of wearing anti-masks.
- If you wear a reverse, the exhaled water vapor will not be able to pass through. If you wear the mask for a while, the barrier will be lost.
Correct practice: Dark side faces outward, and light (white) side faces in.
3. Touch the outside of the mask when removing it
- The outer layer of the mask is the dirtiest. Taking it out by hand directly will open the channel for the virus to spread.
Correct practice: Do not touch the outer side of the mask, just hold the ear strap to remove it; wash your hands after taking off the mask, and do not remove the mask if you do not have hand washing conditions.
4. Wear masks wherever you go
- Such masks wear out quickly.
Correct practice: When healthy adults are alone, such as driving and walking on their own, there is no intensive personnel contact, and they may not wear masks.
5. The mask is sprayed with alcohol or steamed for high-temperature disinfection
- Doing so will cause the outer material of the mask to be denatured, and the filtering function of the mask will be reduced or even invalid.
- If you do n’t go to a crowded public place, you do n’t need to sterilize the masks for recycling.
Correct practice: Dry in a clean and ventilated place, or store in a clean and breathable paper bag.
6. Mask disinfection in the sun
- The new coronavirus will only be killed when it is at a temperature above 56 ° C for 30 minutes, or under a certain dose of ultraviolet radiation.
- When the sun irradiates the mask, it can not reach 56 ° C, and the UV intensity is not enough in the current season.
Correct practice: Discard the used mask, do not disinfect it yourself.
7. After the mask is used, cut it up
- Masks can block droplets, but it is not clear how long and how long the virus will remain on the outside of the mask.
- Shredding the mask is likely to touch the outside of the mask, increasing the risk of infection.
Correct practice: Masks that are used up daily are discarded in closed garbage bags.
8. The thicker the mask, the better
- Medical-surgical masks are thin to the touch, but can effectively block virus invasion.
- The ordinary cotton masks on the market, although thick, have little effect in preventing infectious diseases.
Correct practice: choose the appropriate mask type without excessive protection.
9. Do not remove the mask during security
- During security screening, face recognition requires a short time to remove the mask, and there is generally no risk of infection.
Correct practice: Pay attention to keeping a certain distance from others, and wear a mask quickly after the security check.
