Final answer:
Respirable crystalline silica dust is a hazardous substance that can cause lung diseases when inhaled. Workers in industries such as mining and construction should take precautions to minimize exposure.
Step-by-step explanation:
Respirable crystalline silica dust is a hazardous substance that poses health risks when it is inhaled. Respirable crystalline silica dust is a hazardous substance that can cause lung diseases when inhaled. Workers in industries such as mining and construction should take precautions to minimize exposure.
Silica dust is generated during activities such as mining, quarrying, and construction. When workers are exposed to high levels of silica dust over time, it can lead to lung diseases such as silicosis, lung cancer, and chronic obstructive pulmonary disease (COPD). It is important to take proper precautions and use protective equipment to minimize exposure to silica dust.
