Long-term inhalation of dust, smoke, and fog (collectively referred to as particulate matter) in the air of workplaces can cause damage to the respiratory system of workers and even pneumoconiosis. Pneumoconiosis is still the most serious occupational disease in China. The Sichuan Safety Supervision Bureau (Sichuan Coal Supervision Bureau) reminds you that it is important to prevent the pneumoconiosis and protect the health of the workers in order to contact dust workers with suitable dust masks. So, how to choose the right dust mask?

There are many kinds of dust masks on the market, and the quality is different. To choose a good dust mask can be considered from the following four aspects:

1, safety performance. Before ordering a mask, consult an industrial or occupational safety specialist to find out if the mask is suitable for the appropriate working environment. According to the standard of GB2626-2006, the dust mask that has the highest level of domestic protection at present is the N100 dust mask. The filtering efficiency of ultrafine dust is as high as 99.97%, which can meet the needs of most working conditions.

2, comfort. Masks made of materials that are close to the touch of the human body are usually more comfortable. The most suitable one on the market is a mask made of high-quality medical silicone materials. At the same time, the breathing resistance of the filter cotton must be low to improve the working efficiency of the mask. Avoid breathing difficulties during use of the wearer.

3, convenient and practical. In actual use, people do not have much time to take care of a mask, so be sure to choose a mask that is convenient and easy to wear. At the same time, it is also necessary to consider that the mask and the face should closely fit each other, so as to prevent the air from entering the respiratory tract directly from the gap between the mask and the face without filtering through the filter cotton.

4, the last thing to consider is the economy, choose a long life, good quality dust masks can not only achieve the effect of dust prevention, but also reduce the investment in comprehensive protection costs.

In addition, it should also be noted that in addition to employing suitable dust masks, employers must also step up training for dust-contact workers and urge them to use them properly so that workers can inhale particulate matter as little as possible in order to achieve prevention of pneumoconiosis more effectively. the goal of.
