举一反三
- Isolate the facility from the general mine air circuit is the methods for reducing exposure to silica dust. A: 正确 B: 错误
- To effectively control the respirable coal and silica dust exposure of mine workers, it is not necessary to identify the sources of dust generation and quantify the amount of dust liberated by these sources.
- A doctor may diagnose CWP or silicosis based on the combination of an appropriate history of exposure to coal mine dust or silica, compatible changes in chest imaging or lung pathology, and absence of plausible alternative diagnoses.
- Many practical areas of engineering controls designed to mitigate exposure of surface mine workers to all airborne dusts, including silica, are： A: drill dust collection systems B: enclosed cab filtration systems C: controlling dust on unpaved haulage roads D: controlling dust at the primary hopper dump
