摘要:
目的 介绍一种用EASC-IHSTAT 软件进行职业暴露监测数据处理和决策的方法。 方法 用EASCIHSTAT软件对某厂某车间电焊工接触的电焊烟尘的时间加权浓度数据进行统计学分析,并推断出总体的数据分布类型和超过职业接触限值(occupational exposure limits,OEL)数据的百分比,然后参照美国职业安全与健康管理局5%的判定界值,做出该工作场所空气中电焊烟尘浓度对标准依从性的定性判定。 结果 该工作场所监测的电焊烟尘浓度均低于OELs,但按EASC-IHSTAT 软件结果分析,该工作场所空气中电焊烟尘浓度超过OEL 的比例达到10.6%。 结论 对工作场所职业病危害是否符合标准而言,EASC-IHSTAT 方法对判定为“合格”的条件比我国大陆现行方法的要求更严格。 Abstract:Objective To introduce a method assisting occupational exposure data processing and decision making using EASC-IHSTAT software. Methods EASC-IHSTAT software was used to estimate data distribution and percentage of samples exceeding occupational exposure limits (OELs) for a group of time-weighted welding fume concentrations data collected in a workshop. Applying the U.S. Occupational Safety and Health Administration's boundary values of 5%, a qualitative judgment on compliance to the national standards of welding fumes would be made for the selected workplace. Results All concentrations of welding fumes sampled in the workplace were below OELs, but 10.6% of the samples were above OELs according to EASC-IHSTAT software. Conclusion In regard of determining qualification of occupational exposures in compliance with relevant national standards, the protocol adopted by EASC-IHSTAT software is more rigorous than the current method in China.
