Pay attention to rheumatism and dust prevention, and do a good job of dust prevention in coal mine environment for a long time to avoid and prevent pneumoconiosis.

Pneumoconiosis refers to the long-term exposure of workers to high dust environment, because inhaling a lot of dust leads to a lot of dust accumulation in alveoli and pulmonary fibrosis, which leads to the occurrence of diseases. Generally manifested as shortness of breath, fever, fatigue, dry cough and dyspnea. In severe cases, it will lead to other diseases and life-threatening.

If you choose a mask, it is recommended to choose a mask as follows:

1, dust mask as a special labor protection articles, must pass the certification of GB2626-2006.

2. Masks are divided into disposable, replaceable cotton filter-type half masks and full masks. For long-term occupational protection, it is recommended to use a replaceable cotton half mask. Occasionally go out to work, you can choose a disposable dust mask.

4. For dust and oily particles, protective masks are divided into oil-proof (oil fume, oil mist, dust, smoke, fog and microorganisms, denoted by KP) and dustproof (dust, smoke, fog and microorganisms). There are three levels of protection against dust: KN 100, KN95 and KN90. If there are many kinds of pollutants in the working environment, which are harmful to people, it is suggested to choose KN 100.
