Proper use, storage and cleaning of masks are the key to maintaining their effectiveness. What are the precautions for citizens to wear masks on a daily basis:
1. Wear the mask correctly to ensure that the mask covers the mouth, nose and chin, and the nose clip is pressed tightly;
2. The mask is dirty, deformed, damaged and has peculiar smell, which needs to be replaced in time. The cumulative wearing time of each mask shall not exceed 8 hours;
3. Masks used in cross regional public transport or hospitals are not recommended to be reused;
4. Masks that need to be reused should be hung in a clean, dry and ventilated place;
5. In case of suffocation, shortness of breath and other discomfort when wearing the mask, take off the mask immediately and place it in an open and ventilated place;
6. When going out, carry a spare mask and store it in the original packaging bag or clean storage bag to avoid extrusion and deformation. Waste masks belong to other garbage disposal.
The continuous demand for masks and the expanded production of masks may make hundreds of millions of masks circulate. Then these disposable masks can not be reused after wearing. What should we do to avoid new infections?
In hospitals, medical waste is usually divided into black, yellow and red. Among them, domestic waste in black plastic bags, medical waste in yellow plastic bags (including infectious waste), radioactive waste in red plastic bags and other special medical waste. These used disposable masks are put into clean and sealed bags and thrown into the Yellow dustbin.
Masks belong to medical waste. According to the classification catalogue of medical waste, cotton balls, cotton swabs, drainage surfaces, gauze and other dressings; Disposable sanitary articles, disposable medical articles and disposable medical devices belong to infectious waste. In addition, more masks are used outside the hospital to prevent and avoid infection. They may not be infected with the virus. How should we deal with them?
In cities with strict regulations on waste classification and treatment, it is suggested to put used masks into plastic bags and other sealed bags and put the sealed bags into harmful garbage cans in accordance with the principle of prudence and from the perspective of maximizing the protection of public life and health.
In city where there is no strict garbage classification, the respirator with alcohol spray can be bagged and sealed. 75% of high temperature and medical alcohol can kill COVID-19.
In the new version of the mask wearing guide, key occupational groups mainly involve high-risk posts of overseas input and pollution transmission, staff of medical institutions and service personnel in public places.
The first category is the high-risk personnel imported from abroad and the diffusion of pollution, focusing on the posts related to overseas cold chain food transportation, such as customs officers, cleaners, porters, drivers, etc. Strengthen protection, wear particle protective masks at work to prevent the transmission risks of economic substances, environment and people.
The second category is the staff of medical institutions. In addition to the key protection of service personnel and staff in direct contact with patients or infected persons, personnel exposed to potential pollutants, such as cleaners, nurses, plumbers, laboratory staff, etc., wear anti particulate masks, and other hospital staff, such as security guards, doctors, etc. Wear a medical surgical mask or a higher level of protective mask.
The third category is the service personnel in public places, such as stewardess, police, couriers, etc. in the past, they needed disposable medical masks. This revision is upgraded and strengthened. It is required to wear medical surgical mask or higher-level protective mask during work.
In recent years, due to overseas tourism, entry and exit and other reasons, some places have added some new ones. At present, it has involved many fields in many cities. In order to prevent the epidemic from fighting back, people should pay attention to wearing protective masks.
It has been more than two years since the outbreak. From inadequate preparation to strict control, China has invested a lot of manpower and energy, and finally achieved good results. However, in other countries, the epidemic prevention and control is not strict, resulting in very serious consequences.
It can be seen from the figure that the cumulative number of deaths from the epidemic abroad is very terrible.
No matter where you go or in which city, please remember to wear a protective mask to ensure your safety.
In the past, few people used to wear masks when traveling. Now people wear masks for health reasons. What kind of masks do we usually use? Most of us use disposable medical masks.
1. There are many kinds of disposable medical masks, which can be used by adults and children. They are very suitable for wearing.
2. The mask is mainly composed of non-woven fabric. Its production process is strictly sterile, which can reduce people's adverse reactions when wearing.
3. It can effectively block dust, dust, particles, droplets and other substances in the air and play a good protective role.
4. It is mainly composed of three layers with good air permeability. It can prevent the mask of harmful substances from entering our respiratory system and protect users.
5. There are many kinds of medical masks, including medical protective masks, medical surgical masks and ordinary medical masks, which can be purchased on demand.
With the outbreak of the epidemic, we need to wear masks every day. Have you ever observed the mask you're wearing? Most of them are medical masks, which have a good protective effect and have a good protective effect on us. Let's see. 1. There are many kinds of medical masks. We usually use medical protective masks and kf94 masks. In addition, medical surgical masks and ordinary medical masks are also included.
Disposable products are disposable. You can't use it!
Disposable masks should not be reused, because the protection time of disposable masks is limited, generally about 4 hours. If it is reused for more than 4 hours, the protective effect will be reduced, which is not conducive to the prevention of infectious diseases.
If the disposable mask is worn many times, it is relatively harmful. First, the filtration efficiency will be greatly reduced, and the droplets in the air cannot be effectively separated, which greatly reduces the effect of preventing virus infection. Then wear it many times. If disinfection is not timely, cross infection is easy to occur, which is very dangerous.
