What are the precautions when wearing a mask?

It should not be worn for too long. If you wear a mask for a long time, the nasal mucosa will become fragile and lose the original physiological function of the nasal cavity, so you cannot wear a mask for a long time. Masks should only be worn in special settings, such as in crowded places with poor air circulation.

Of course, when walking in the wild, a mask can also protect against wind, sand and cold, or when moving in an environment with air pollution, you need to wear a mask, but it should not be too long.

The outer layer of the mask often accumulates dust, bacteria and other harmful substances in the outside air, while the inner layer is responsible for blocking the exhaled bacteria, saliva, etc., so the two sides cannot be used alternately, otherwise the dirt contaminated by the outer layer will be directly attached to the face, thus inhaling the human body and becoming a source of infection.

1. Wash your hands before putting on a mask and after taking it off.

2. Pay attention to the front and back and up and down when wearing the mask, the mask should cover the mouth and nose, and adjust the nose clip to fit the face.

3. During wearing, avoid touching the inside and outside of the mask with your hands, and take off the mask by taking off the two ** ropes.

4. Wearing multiple masks does not effectively increase the protective effect, but increases breathing resistance and may destroy the tightness.

5. There is no evidence to prove the effectiveness of various measures such as cleaning and disinfection of masks.

6. Disposable medical masks and surgical masks are limited to use, and the cumulative use does not exceed 8 hours.

When wearing a mask, you need to be careful not to let your mouth and mask come into contact too much.

Wear a mask close to your face.

Change your mask frequently.

Precautions for wearing a mask:

The first is to wear the mask correctly, make sure the mask covers the mouth, nose and chin, and the nose clip should be compacted.

Second, when the mask is dirty, deformed, damaged, or smelly, it needs to be replaced in time, and the cumulative wearing time of each mask does not exceed 8 hours.

Third, it is not recommended to reuse the mask that has been used in cross-regional public transportation or in hospitals and other environments.

Fourth, masks that need to be reused should be hung in a clean, dry and ventilated place when not in use.

Fifth, if you feel uncomfortable such as suffocation and shortness of breath during wearing a mask, you should immediately go to an open and ventilated place to remove the mask.

Sixth, when you go out, you should carry spare masks and store them in the original packaging bag or a clean storage bag to avoid squeezing and deformation, and the discarded masks should be classified as other garbage for disposal.

New requirements for key occupational groups to wear masks:

The first category is personnel in high-risk positions of overseas import and pollution transmission, with special emphasis on strengthening the protection of customs staff, cleaners, porters, drivers and other positions related to overseas cold chain food and transportation, and wearing particulate matter protective masks throughout the work period to prevent the risk of transmission through objects, the environment and people.

The second category is the staff of medical institutions, in addition to the key protection of medical personnel, staff in direct contact with patients or infected people, personnel who are in contact with potential pollutants, such as cleaners, nurses, plumbers, laboratory staff, etc., wear particulate matter protective masks, and other hospital staff, such as security guards, medical guides, etc., wear medical surgical masks or masks with a higher level of protection.

The third category is service personnel in public places, such as flight attendants, police officers, couriers, etc., who were previously required to wear disposable medical masks, but this revision has been upgraded and strengthened, requiring them to wear medical surgical masks or masks with a higher level of protection during work.

In order to avoid the infection of the new pneumonia, we need to wear masks when we go out to effectively prevent human-to-human transmission, because the transmission of pneumonia is mainly the transmission of droplets, and masks can block droplets to a certain extent. But masks are not a panacea, especially the way to wear masks, if you don't have a blind and correct wearing of masks, there is no protective effect. So what are the precautions for wearing a mask?

Let's talk about it in detail now.

Note 1:

We should do our hands before wearing the mask, or do not touch the inside of the mask with our hands during the whole process of wearing the mask, because the inside of the mask will be in contact with our mouth and nose, and if it is contaminated, it will have a great impact, so washing hands and avoiding touching the inside of the mask is the most noteworthy point.

Note 2:

Before wearing a mask, we must distinguish the front and back of the mask before wearing it correctly, generally we often use medical surgical masks are mostly white on the inside, and the direction of the side with the metal strip is the top, and the metal strip needs to be pressed and the nose wing is closely fitted in order to play a better protective role.

Note 3:

When taking off the mask, do not touch the surface of the mask, because the surface of the mask is the side that touches the most pollution sources, and if you touch it easily, it may become cross-infection, so we need to take off the rope on the ear when taking off the mask, and then fold it from the inside of the mask before processing, so as to reduce the danger of taking off the mask and touching the virus.

1. Friends with medical protective shields and respiratory protective equipment should be replaced for a maximum of 8 hours of continuous use. If there is damage and the air tightness is not good, it is recommended to replace the mask immediately.

2. Friends who wear disposable surgical masks should change their masks every 4 hours, and if they are damaged, please change the masks immediately.

3. Friends who need the best type of protective mask, to choose a medical protective mask, it is recommended to choose N9X or KN9X masks, and at the same time choose a mask with a standard number of GB19083-2010.

4. It is necessary to pay attention to the tight-fitting choice of a mask with a breathing valve, which is designed as a one-way valve to allow the expiratory airflow to be discharged, but not to let the inhalatory airflow through. In particular, people with the virus do not have the option of wearing a mask with a breathing valve.
