**课程名称：** 结晶二氧化硅危害意识 **课程概述：** 本课程旨在提高人们对可吸入结晶二氧化硅危害的认识。每年有数百万工人可能在不知情的情况下暴露于这种危险物质。在这约200万的工人中，有84万人暴露于超出安全限量的二氧化硅。其中90%的工人来自建筑行业。 从事切割、锯切、钻孔、破碎混凝土、砖块、陶瓷砖、岩石和石材等建筑 activity 的工人，正将自己置于罹患可吸入结晶二氧化硅引起的致命疾病的风险之中。保护这些工人的工具和培训是可获得且经济的，但目前这些安全措施尚未得到充分实施，导致了本可避免的工人死亡。 暴露于可吸入结晶二氧化硅可导致矽肺病（silicosis）、肺癌以及其他呼吸系统和肾脏疾病。对砂岩喷砂工和岩石钻孔工人等高风险职业中发生的残疾性疾病和死亡案例的研究，进一步强调了结晶二氧化硅健康危害的严重性。 **教学大纲：** 无
Respirable crystalline silica is a dangerous hazard that millions of workers are unknowingly exposed to every year. Of these estimated 2 million workers, 840,000 of them are exposed to an amount of silica that exceeds the permissible exposure limit or the amount of exposure deemed safe. 90% of the individuals exposed to this material are employed in the construction industry. Individuals who perform construction activities such as cutting, sawing, drilling, and crushing of concrete, brick, ceramic tiles, rock and stone products are unnecessarily putting themselves at risk of contracting deadly diseases caused by respirable crystalline silica. The tools and training needed to protect these individuals are widely available and inexpensive. The issue is that these safeguards are not being implemented and therefore workers are losing their lives to these fatal diseases that are absolutely preventable. Exposure to respirable crystalline silica can cause silicosis, lung cancer as well as other respiratory and kidney diseases. The seriousness of the health hazards associated with exposure is emphasized by the amount of disabling illnesses and fatalities that occur in sandblasters and rock drillers, who are among workers at the highest risk of exposure.
