Choose Respirator Standard for Respirators

(1) Respiratory protective equipment standards

Respiratory protective equipment implementation standards are the basis for selecting respiratory protection products, and attention should be paid to preventing the selection of respiratory protection products that the country has explicitly stopped to implement. At present, the National Industrial Product Production Licensing Office announces that: on August 1, 2009, the GB2626-2006 "Respiratory protective equipment self-priming filter-type particle respirator" standard was implemented, and at the same time, it replaced GB2626-1992 "Respiratory protective equipment self-priming filter type Dust mask standard. This is a sign that identifies the quality of the product.

(2) Degree of protection and filtration efficiency

The degree of protection and filtration efficiency are important criteria for protection safety. Because the higher the protection level and the filtering efficiency of the gas mask, the higher the safety to the wearer. The level of filtration efficiency is based on its barrier efficiency against fine dust, especially respiratory dust with a median diameter of 0.075 μm or more. Because this particle size dust can directly enter the alveoli, it has the greatest impact on human health. In general gauze masks, the principle of blocking dust is mechanical filtering. When dust collides with gauze, it is blocked by layers and blocks some large particles of dust in the sand cloth. However, some fine dust, especially 0.075 micron dust, will pass through the gauze mesh and enter the respiratory system. At present, international gas masks are made of filter materials filled with permanently static fibers. Those 0.075-micron respiratory dust are attracted by electrostatic attraction during the process of passing through the filter media, and are trapped on the filter material to capture fine dust. Plays a role in blocking dust.

(3) The degree of closeness between the mask and the face shape.

The air is like a stream of water, where the resistance is small and where it flows first. When the shape of the mask is not close to the human face, dangerous substances in the air will leak from the place where the gas mask does not fit into the human respiratory tract. Well, even if you choose the best filter mask. It also cannot protect your health. Now many foreign regulations and standards stipulate that workers should regularly perform masks adhesion tests. The purpose is to ensure that workers choose appropriate masks and wear masks in the correct steps.

(4) comfortable to wear.

Requirements. Gas masks have low resistance to breathing, light weight, no odor, no irritating to the skin, wearing hygiene, and easy installation. This way workers will be willing to insist on wearing and improving their work efficiency in the workplace.
