Xinhuanet, Shenyang, November 12 (Reporter Xu Yang) The northern region has entered a period of frequent smog. An important way for the public to deal with smog is to wear masks. The reporter’s investigation found that there are many kinds of masks on the market, good and bad, and there are no national standard mask technical specifications for haze prevention.
The reporter’s interview found that there are basically two types of masks commonly used in the market. One is medical masks, whose main function is to prevent saliva infection between doctors and patients, but has little effect on preventing and controlling haze; the other is industrial protective equipment, which can protect against haze. Particles in the air act as interceptors.
Bi Deli, director of the Low Carbon Development Institute of the Liaoning Academy of Social Sciences, said that the national standard “Respiratory Protective Equipment, Self-priming Filtering Anti-Particulate Respirators” (GB2626-2006) released by my country in 2006 was basically formulated for labor protection equipment and was not Completely suitable for public haze prevention.
“For example, this standard sets the temperature for product device detection to 25°C (±5), which is quite different from the winter temperature in northern areas where haze weather is common.” Bidley said that this standard is related to prevention and control in aspects such as detection and application. The haze requirements are not met. Establishing material standards for the production of anti-haze masks can expel fake and inferior products from the market and prevent lawless people from taking advantage of policy loopholes. At the same time, it is also necessary to formulate technical requirements and monitoring methods for the production of anti-haze masks and face shields, and standardize the production of high-quality products by enterprises.
The reporter consulted the Liaoning Provincial Quality Supervision Department, and the other party stated that there is currently no national standard for anti-haze masks. In this regard, Bidley believes that safety standards for anti-haze masks and face shields worn by people with various physical conditions should be formulated at the national level, and it is recommended to adopt production approval and market access systems.
