一、前言 在法国和其他许多国家,鉴定矿区粉尘量的大小是由固定位置的粉尘采样仪进行环境监测来完成的。 然而,要判断工人实际接触的粉尘量,只有让工人在工作岗位上,在整个滞留期间把测量仪器放在自己的呼吸道旁进行个人受害监测,其结果才更有代表性。 为了满足这一要求,法国煤矿科学研究中心研制出一种CIP10型个体粉尘采样器,它体积小,便于携带,在可能碰到的任何困难的情况下均可使用。
I. INTRODUCTION In France and many other countries, the amount of dust in certified mines is measured by environmental monitoring of a fixed-position dust sampler. However, judging the amount of dust actually exposed to workers, the result is more representative only if the workers are allowed to place their measuring instruments on their respiratory tract for personal victimization at work, throughout their stay. In order to meet this requirement, the French Coal Mine Scientific Research Center has developed a CIP10-type individual dust sampler that is small, portable and can be used in any difficult situation it may encounter.
