[Real-time] The new "national standard" for civilian masks was implemented on the 1st

As the weather turned cold, more and more Linfen citizens wore masks. Masks not only keep warm and keep warm, but also block the spread of germs. In recent years, haze weather has become the focus of social attention. Due to the lack of a unified standard, products on the market are mixed, and finding a mask that can really prevent it has become a pressing need for many citizens. On November 1st, the national standard for protective masks for civilian use - "Technical Code for Daily Protective Masks" was formally implemented. In the future, masks will be purchased and produced.

Originally sold masks have not been removed

On the 1st, at a pharmacy in the east section of Gingershan Road, the reporter found that the pharmacy mask counter had nearly 10 kinds of masks. Varieties include ordinary cotton masks, medical disposable masks, N95 masks, anti fog masks and so on. Its price ranges from a few yuan to tens of yuan. As long as there are masks with the words “anti-fog and haze” on the packaging, the price is obviously higher than that of ordinary masks, and the price is generally more than 20 yuan.

According to the staff, she has learned about the "national standard" mask for civilian masks, but the current "national standard" masks have not arrived yet and the original masks for sale have not been removed.

From the perspective of packaging, various masks are implemented in different standards, including YZB. The reporter learned that most of the standards implemented on the market before the masks were corporate standards. Some of them implemented the "industrial respiratory protective equipment self-priming filter particulate respirator" industrial mask standard, but also "medical protective mask technical requirements" medical product standards, market The sign is confusing and there is no uniform standard for judging.

At a pharmacy in Luzhou Road, Ms. Song is purchasing masks. Ms. Song told reporters that she bought masks simply based on the outer packaging of the masks. He had also purchased disposable medical masks and anti-fog masks. "Especially anti-fog and smog masks, there is no uniform production standard, is it really able to play the role of anti-fog and haze, as consumers are really unclear." Ms. Song said.

Ordinary medical masks have little effect in preventing caries

“Before industrial masks standards have been introduced, and now national standards for protective masks have been issued to allow mask manufacturers and consumers to have a unified standard and basis.” 13 years of labor protection mask business, Linyi Xin Minghui Safety Technology Co., Ltd. Chairman Li Hui said.

According to Li Hui, industrial masks and civilian masks have strict differences and limitations. In general, industrial masks can protect PM0.3, that is, they can protect particles with a diameter of 0.3 microns. A civil mask can protect PM2.5, which is to protect particles with a diameter of 2.5 microns. From this point of view, the implementation of industrial masks is higher than the civil masks, but in terms of structure, wearing time, etc., there are strict differences between the two, so can not simply say that in order to prevent haze, ordinary people can wear industrial masks . Li Hui said that after the introduction of the new civilian “national standard”, it can promote industry regulation, and both industrial and civilian standards can “perform each other”.

Li Hui told reporters that whether or not a mask can prevent haze is mainly determined by its structure. Medical disposable masks can play a role in preventing saliva splashing and keeping warm; ordinary cotton masks mainly play a role in keeping warm, but both prevent haze. The role is not great.

Li Hui said that the use of masks for the new "national standard" is an ordinary person other than children. "The reason why children are excluded is because children are in a period of growth and development, and their physical characteristics are quite different, so they cannot be applied to adult standards."

People choose masks to consider adhesion, etc.

It is understood that, according to the new "national standard", the protective effect level of masks is divided into A, B, C, D four levels; corresponding protective effect of each level is not less than 90%, 85%, 75%, 65%; The applicable air quality index categories are: severe pollution, severe and sub-pollution, heavy and sub-pollution, moderate and sub-pollution. According to the new “National Standard”, masks can be used to reduce the concentration of inhaled PM2.5 to 75 micrograms per cubic meter or less, so that the quality of the air after inhalation in the filtered body reaches a good or above level, which is a qualified mask.

"Now consumers have to buy masks based on the judgment, will not blindly choose." According to an industry source, the new "national standard" after landing, consumers can choose according to air pollution and mask protection level suitable mask to wear.

“Choose a mask that suits you. People should consider three aspects of the filtering efficiency, closeness and comfort of masks.” According to industry sources, the filtering efficiency is related to the material structure. The adhesiveness is whether the mask can be closely attached to the face. Together. In addition, comfort is also an aspect that consumers should refer to, and should allow them to breathe more smoothly. “The consumer should buy masks from regular, qualified companies and don’t blindly buy expensive masks.”
