对贵州省化工厂三硝基甲苯(TNT)作业人员连续几年作劳动卫生调查。对不同作业场所作了空气中TNT粉尘浓度监测。调查表明1988年工艺改革后车间空气TNT浓度已降至国家规定标准,但TNT对眼晶状体的损害(简称晶体)仍然有发生。现将1990—1992年对该厂调查结果分析如下。内容和方法 1.调查其生产工艺,防护设施及工人自我防护和卫生习惯等。 2.作业场所空气中TNT粉尘浓度监测,用防爆采样器,在破碎、筛药、条装(装药)、包装等生产岗
For the third consecutive year, TNT workers in Guizhou Chemical Industry Factory made a survey on labor hygiene. TNT dust concentrations were monitored in air at different workplaces. The survey showed that after the process reform in 1988, the TNT concentration of the air in the workshop has dropped to the national standard, but the TNT damage to the lens of the eye (crystal for short) still occurs. Now 1990-1992 on the plant survey results are as follows. Content and methods 1. Investigate the production process, protective facilities and workers self-protection and hygiene habits. 2.Workplace air TNT dust concentration monitoring, with explosion-proof sampler, broken, sieve medicine, strip (loading), packaging and other production Kong
