People working in a widespread, persistent dust environment are at great physical risk. This is because dust is a very small diameter solid particle that can be inhaled and deposited in the lungs through the respiratory tract. If you work in such an environment for a long time, the more productive dust in the lungs will be inhaled for a long time, and the more it is deposited in the lung tissue causing extensive lung inflammatory reactions, such as pneumoconiosis and silicosis, which can cause diffuse fibrotic changes in the lungs for a long time. Moreover, the lung function will decrease, causing breathing difficulties and even respiratory failure in severe cases, which will have an impact on the normal life and work of individuals.
