采用职业卫生现场调查法,现场采样,实验室检测分析,根据《工作场所空气有毒物质测定铟及其化合物》(GBZ/T160.83—2007)等相关标准及规范对某线路板焊锡车间作业人员接触铟及其化合物的浓度水平进行分析评价。元件更换锡焊工、验收锡焊工和维修锡焊工接触铟及其化合物的时间加权平均浓度TWA较高,最高达0.07 mg/m3;元件更换锡焊工、验收锡焊工和维修锡焊工短时间接触浓度STEL最高值达0.07 mg/m3。该生产车间一线生产工人接触铟及其化合物虽不超标,但应加强职业病防护设施的正常运转,加强工人的个体防护意识。加强铟及其化合物毒理性质的研究,从源头控制和消除职业病危害。
Using occupational health field survey, on-site sampling, laboratory testing and analysis, according to “workplace air toxic substances Determination of indium and its compounds” (GBZ / T160.83-2007) and other related standards and norms of a circuit board solder shop workers The levels of exposure to indium and its compounds were analyzed and evaluated. Component replacement tin solders, acceptance tin builders and maintenance tin solders Contact indium and its compounds time-weighted average concentration TWA higher, up to 0.07 mg / m3; component replacement tin solders, tin workers and repair inspection tin solder short-term exposure to concentration STEL The highest value of 0.07 mg / m3. The first-line production workers in the production workshop are not exposed to indium and its compounds. However, the normal operation of occupational disease prevention facilities should be strengthened so as to enhance workers’ individual protection awareness. Strengthen the research on the toxicological properties of indium and its compounds and control and eliminate occupational hazards from the source.
