What causes pneumoconiosis? Stay away from high-risk jobs

Pneumoconiosis is common in people who work in dusty environments, such as miners and cleaners. It is a lung disease that develops over time when dust is inhaled into the lungs and cannot be excreted, affecting the normal functioning of the lungs.

1. In a production environment, pure quartz dust rarely exists. Usually, multiple types of dust exist, and the combined effects of mixed dust should be considered.

2. Workers' individual factors and health conditions also play a role in the occurrence of pneumoconiosis.

3. The higher the free silica content in the dust, the shorter the onset time and the more serious the lesion.

4. The severity of silicosis is related to the amount of dust accumulation in the lungs, which mainly depends on the concentration and dispersion of the dust, the time of exposure to dust and the protective measures. The higher the dust concentration, the greater the dispersion, the longer the working years of dust exposure, the poorer the protective measures, the greater the amount of dust inhaled and accumulated in the lungs, the more likely silicosis will occur and the more serious the condition will be.

Working in what kind of environment is more likely to cause the disease: 1. Mining: Mining of various metal mines, coal tunneling and coal mining, and mining of other metal mines are the main working environments for producing pneumoconiosis. The main types of work are rock drilling, blasting, pillaring, and transportation; 2. Crushing, screening, and transportation of ore in metal smelting; 3. Sand preparation and molding in casting in institutional manufacturing, sand cleaning, sand blasting, and welding operations for castings; 4. Building materials industry, such as mining, crushing, grinding, screening, and mixing in the production of refractory materials, glass, cement, and stone; mining, transportation, and textile of asbestos; 5. Tunneling and blasting in highway, railway, and water conservancy construction. Nanjing Pneumoconiosis and Silicosis Research Institute.
