How can crystalline silica harm workers? | 晶体硅对工人有何危害? |
Very fine particles of crystalline silica dust present a hazard when inhaled into the lungs. Airborne dust is most likely to occur when materials or products containing silica in the workplace are cut, sanded, drilled or any other job which creates fine dust. Depending on factors such as how much dust a worker breathes in and for how long, crystalline silica can cause the following health effects:
Applying adequate controls such as minimising the generation of airborne dust can reduce hazardous exposures and prevent illness in the workplace. | 诸如结晶二氧化硅粉尘等非常微小的颗粒被吸入肺部时,就会造成危害。当工作场所中含有结晶二氧化硅的材料或产品被切割、打磨、钻孔时,或进行任何可能产生微小粉尘的工作时,很有可能产生粉尘。 根据不同的因素,例如工人吸入粉尘的数量多少以及时间长短,结晶二氧化硅会导致以下健康影响:
采取适当的控制措施,例如尽可能减少粉尘的产生,可以减少接触危险而预防工作场所的疾病。 |

Where is crystalline silica used? | 结晶二氧化硅在哪里使用? |
Crystalline silica is a very common mineral used in manufacturing building products and construction materials. Engineered materials containing silica, such as composite stone, are used to fabricate kitchen benches and countertops. Workers can come across crystalline silica when undertaking construction works that require excavation or tunnelling through quartz containing rocks such as shale and sandstone. | 结晶二氧化硅(crystalline silica)是制造建筑产品和建筑材料十分常用的矿物质。含结晶二氧化硅的工程材料,诸如复合石等,用于制造厨房台面和柜台台面。在需要开挖或穿过石英岩(如页岩和砂岩)的工程施工时,工人可能会接触结晶二氧化硅。 |
