Scientific Wearing Masks Should Take Four Steps.

Beijing industry and Commerce Department recently found that a number of brand "anti fog haze" masks were suspected of false propaganda, and "propaganda against fog and haze", "anti PM2.5" and "100% safety" exaggerated the actual efficacy of masks. Mask is an important protection tool for many people to cope with fog and haze. Wearing a mask What's particular about it?

　 The standard of anti PM2.5 civilian mask is not published.

Recently, Beijing Haidian industrial and commercial sub Bureau North Taiping Industrial and commercial area in the area pharmacy inspection found that many brands of masks were printed on the word "PM2.5" and so on. The staff said that the state has not yet issued the production standard of PM2.5 anti respirator, and the standard of mask production is the industrial standard that must be achieved in the dust environment. The highest protection ability for PM2.5 class airborne particulate matter is 93.9%, and the publicity terms on "masks" and "filtration effect" are 99%, which exaggerates the actual efficacy of respirators.

According to the industry and Commerce Department's investigation, a brand name mask is used for "cover dust", "double microfiltration" and "peace of mind hundred percent" and other publicity terms are registered trademarks of their companies, which have not been approved yet. It is easy for enterprises to mislead consumers by using these registered trademarks and printing them on products without obtaining approval.

　　 Wearing a mask Wash your hands before you wash them.

At present, the temperature has changed greatly in the morning and evening. People who are more sensitive to climate change can choose to wear disposable medical surgical masks or 12 or more gauze masks.

Scientific wearing masks should be divided into four steps. One wash: clean hands, so as to avoid dirty hands polluting the inside of the respirator; two hang: put the mask on the face and nose, hang the ends of the rope on the ears with both hands; pull the hands together: pull the wrinkles of the mask at the same time, and make the mask completely cover the mouth and nose and chin; four pressure: press the metal strip on both sides of the nose bridge with the index finger of both hands, so that the top of the mask can be tightly attached to the bridge of the nose. Four. In addition, medical surgical masks have both sides. When wearing masks, they should have a darker side, that is, blue or green, facing outwardly, with a lighter face, facing the face. The mask is also divided up and down. One side of the metal strip is on the upper end. When wearing it, it should stick to the bridge of the nose.

　　 Choose fashion color mask carefully.

Some young and beautiful girls like beautiful color masks. Guo Xiheng, Professor of Department of respiration at Chaoyang Hospital, said that generally qualified respirators are colorless masks. Their materials are made of gauze and non-woven fabrics, without any chemical treatment, no odor, and good ventilation and filtration. Therefore, they are safer and cleaner. Most of the fashionable color masks are made of chemical fabrics, and the patterns and colors are also dyed by dyestuffs. There may be some stimulating odors. Some of the color masks are different in color and air permeability. although The use is beautiful, but there are health risks.

Guo Xiheng suggested that when buying masks, it is best to go to regular hospitals or pharmacies and never buy them at roadside stalls. If you choose to purchase medical, dust and other special function masks, you should also check whether there is a production license number on the packaging, try to require suppliers to produce the inspection report of the goods and the manufacturer's production license.

Haze days, children must be protected.

In response to fog and haze, apart from mask, air purifier is also one of the sharp weapons. Many parents have bought home air purifiers for their children, and some parents have also raised funds to purchase air purifiers for kindergartens. As we all know, there are quite a few of them.

Xu Rongqian, a professor at Beijing University of Chinese Medicine, said that infants under ten years old had short nasal cavity and less filter hair in the nasal cavity. Their ability to filter harmful substances was very limited, while their immunity was low. They really needed special protection.

Therefore, it is necessary to make proper protection for children in haze days. However, due to the fragile respiratory system of children, special attention should be paid to purify the air purifier. Specifically, we should do three things: first, see the filter grade; second depends on the thickness of the filter element, the thicker the natural, the third is the design of the air duct, the stronger the wind, the stronger the purification capacity.
