摘要
目的通过对某火炸药作业场所乙酸乙酯浓度检测以及作业人员职业健康检查,分析乙酸乙酯对作业人员健康的影响。方法对作业场所空气中的乙酸乙酯检测按照GBZ/T 160-2004方法进行采样分析;依据GBZ 188-2007对作业人员进行职业健康检查,对其结果进行统计分析。结果该作业场所的造粒间、混合间、烘干间和室外清理乙酸乙酯短时间接触浓度超标,造粒和洗料下料操作工的乙酸乙酯时间加权平均浓度超标。与对照组相比,观察组的眼、鼻、口腔和肺功能指标阳性率差异无统计学意义(均P>0.05);观察组咽喉部和呼吸系统自觉症状阳性率(34.2%、43.6%)明显高于对照组(22.5%、25.8%),差异具有统计学意义(均P<0.05)。结论乙酸乙酯对作业人员的咽喉部和呼吸系统有一定的影响,可对作业人员的身体健康造成职业危害,应加强对作业人员的防护。
Objective To analyze the impact of ethyl acetate on workers＇ health by detecting the concentration of ethyl acetate and checking the workers＇ occupational examination in fire explosive workplace.Methods Ethyl acetate in the air of workplaces was detected,according to the standard methods of GBZ/T 160-2004;Workers＇ occupational examination was checked and analyzed according to GBZ 188-2007.Results The STELs of ethyl acetate in granulation rooms,mixed rooms,drying room and the stage of outdoor cleaning exceeded occupational standards,the TWAs of ethyl acetate in the stage of granulation,washing and making exceeded national standards.There was no statistical difference in the positive rate of eyes,nose,mouth and lung function between observation group and control group.The positive rate of throat and respiration system of observation group（34.2%,43.6%） was significantly higher than that in the control group（22.5%,25.8%）,all P0.05.Conclusion Ethyl acetate has certain impact on the workers＇ throat and respiration system,so the protection measures should be strengthened.
