How about doing stone maintenance work.

Hello, I'm happy to answer your question. Regarding the stone processing industry, employees are prone to lung diseases, but this is not an absolute phenomenon. Larger factories will also have more advanced dust treatment. For example, employees must wear dust masks when working, and the use of exhaust fans and sedimentation pools in processing workshops have played a big role. Labor protection is also very important. Let employees eat fungus, pig blood, etc. regularly, which can help clear the lungs and eliminate dust. Comparatively, smaller processing plants are a little worse. If they are not properly protected, they may easily get lung diseases. As you said, the stone maintenance can be better, the dust is almost zero, because when doing the clean floor treatment, it is all water-milled, there is no dust, there is no need to worry. The most important thing is to protect yourself, this is the important thing. I have been working in the stone industry for nearly 20 years and have never suffered from lung disease or pneumonia. The key is to be aware of self-protection. Unlike what is said on the Internet, lung disease can be cured by making stone. Hope it helps.
