It is reported that China
Spin
The product commerce association has just released the PM2.5 respirator group standard, which is the first official release to the public in China, which can effectively protect haze hazards.
Mask
Standard.
Li Jianhua, President of the China Textile Business Association, issued a group standard for "PM2.5 respirator". In recent years, air pollution in China has become more and more serious. Respirators can be said to be the necessary basic protective equipment for outdoor activities. But as we have just mentioned, there are many problems in the market of PM2.5 respirators in China. There are no relevant standards for domestic PM2.5 respirators. There are only industrial dust respirators (GB2626-2006) and medical masks, and some masks are based on N95 standards, or European standards.
Therefore, the unreasonable standards and the confusion of the standard system, on the one hand, have caused the market of the unprotected Shanzhai PM2.5 masks.
But this kind of respirator has strict wearing conditions, and it can easily cause dizziness and other physical discomfort when it is used for more than 4 hours.
Therefore, the standard of PM2.5 respirator is very necessary.
Dr. Zheng Yuming of the Institute of urban environment of the Chinese Academy of Sciences said that PM2.5 protective masks should also be more comfortable in addition to focusing on the protective effect, which is what we call high interception and filtration efficiency, that is to say, respiratory resistance should be relatively small.
In addition, the direct contact between PM2.5 respirator and human nose and mouth requires the consideration of microbiological and pH values. However, the existing GB2626-2006 standards do not require these indicators.
The newly released "PM2.5 respirator" group standard takes into account the above requirements, and also decomposes the dyes of carcinogenic aromatic ammonia into the assessment index, which requires that it be not detectable.
These standards can effectively protect the health of the general population wearing the respirator that meets the standard.
