腈纶粉尘对作业工人健康影响的调查

Investigation of Effect of Notrilon Fibre Dust on Health of Operating Workers

为探讨腈纶粉尘对作业工人健康的影响 ,对某腈纶厂毛条车间进行了劳动卫生学调查。该车间粉尘浓度为4.2(0.1～24)mg/m3 ,主要对接触人员上呼吸道和皮肤有刺激作用 ,同时导致肺通气功能受到明显损伤 ,部分工人胸部X线表现异常。提示车间环境中时间加权平均容许浓度超过2mg/m3、短时间接触容许浓度超过4mg/m3尘的卫生标准不能充分保护工人健康。

In order to examine the effect of nitrilon fibre dust on health of operating workers, labour hygienics investigation was carried out in woollen sliver shop of a nitrilon fibre mill. The dust concentration of the shop was 4.2 (0.1～24) mg/m3. The main irritation effect is exerted on upper respiratory tract and skin of exposed workers. And then lung airflow function was damaged seriously, abnormal X-ray appeared in some of them. The results indicated that the dust concentration in the shop environment exceeded the hygienic standard: time weighted average permitted concentration is 2mg/m3 and permitted concentration in short time exposed is 4mg/m3 and was harmful to the workers.
