一、前言石棉作为一种具有独特性状的矿物纤维已被广泛地使用了数百年。美国著名物理学家萨里科夫经研究后认为,使用石棉时如不加防护,则会引起石棉肺、肺癌与间皮瘤。他还通过观察发现,对于许多致命的病例,石棉往往是其诱因。第一次世界大战前及大战期间,曾为美国海军生产石棉绝缘材料和耐火材料的工人中,此种病例尤为突出,与采用喷射技术时,工人们则在充满石棉粉尘的工作环境中操作。
I. INTRODUCTION Asbestos as a mineral fiber with unique properties has been widely used for hundreds of years. The famous American physicist Surykoff after the study found that if the use of asbestos without protection, it will cause asbestosis, lung cancer and mesothelioma. He also observed that asbestos is often the cause of many fatal cases. Among the workers who produced asbestos insulative materials and refractories for the United States Navy during World War I and during World War II, such cases were particularly prominent. When using jetting techniques, workers were operating in a working environment filled with asbestos dust.
