摘要: 介绍了国内棉纺织厂棉尘控制标准的发展进程和职业接触限值对保护劳动者健康的意义,并进一步比较了中外标准中棉尘接触限值的数值大小及其采样方式上的差异,对GB Z2—2002标准中设立棉尘的时间加权平均容许浓度的接触上限值的必要性提出了不同的观点,针对非正常工作班的限值调整和棉尘的采样粒径及方式进行了探讨,建议分类制定棉尘的接触限值,保证标准的可操作性。

Abstract: This paper introduced the development progress of the cotton dust control standards in cotton mills in China and the importance of cotton dust exposure limit in protecting the health of workers.A comparison of occupational exposure limits and sampling methods of cotton dust between China and foreign countries was made,and a different viewpoint was set forth on the necessity of the upper limit of exposure to the cotton dust of the allowed concentration based on time weighted average regulated in GB Z2—2002 standard.And adjustment of the exposure limit with respect to the workers who are working not according to normal shifts,dust sampling methods,and dust particle sizes were also discussed.Furthermore,it was suggested that exposure limit be regulated according to different groups and the workability of standards be ensured.
