摘要
目的确定某医疗器械产品生产过程中的职业病危害因素及其危害程度,并确定职业病防护设施和职业卫生管理措施的效果。方法通过现场职业卫生调查、检测检验法、职业健康检查和检查表法等方法收集数据和资料,并结合职业病防护设施、个人职业病防护水平,对作业人员的职业病危害因素接触水平进行评价。结果机加车间喷砂机操作工接触的矽尘总尘时间加权浓度为1.6 mg/m^3,呼尘时间加权浓度为0.3 mg/m^3,均超过国家卫生标准,经整改后符合国家职业卫生标准,其余各有毒物质浓度均符合国家职业卫生标准的要求。净化间超声波清洗设备操作工接触的噪声强度为86.2 d B、超声波塑胶熔接机操作工接触的噪声强度为104.8 d B、粉料间粉料机操作工接触的噪声强度为85.2 d B,均超过国家职业卫生标准的要求,其余各操作位工人接触的噪声强度符合国家职业卫生标准。结论职业病危害因素主要为苯、甲苯、二甲苯、铜(按Cu计)铜烟、二氧化氮、氢氧化钠、氢氧化钾、其他粉尘(总尘)、电焊烟尘(总尘)、矽尘、噪声和紫外辐射,其中苯、甲苯、二甲苯、矽尘、噪声的危害程度较高为关键控制点,工人作业时应注意工程防护措施和个体防护措施的有效性。
Objective To make sure the occupational hazard factors and its hazard rating of some medical equipment product in the process of the production and to determine the occupational- disease- prevention facilities and the effect of the occupational health management measures. Methods The methods of field occupational health investigation,detection test,the occupational health examination and checking table and other methods were applied to collect data and information,combined with the occupational- disease- prevention facilities,personal occupational disease protection level,and the contact level of the occupational- disease- inductive factors of the operators was evaluated. Results First,operators of sandblasting machine contact with silicious dust and contacting time in total had weighted concentration reaching 1. 6 mg /m3 in the workshop,and weighted concentration of breathing time had reached 0. 3 mg / m3,exceeded the national health standards,the rest of the concentration of toxic substances should meet the national occupational health standards after rectification in accordance with the national occupational health standards. Secondly,operators of ultrasonic cleaning equipment had contacted noise intensity reaching 86. 2 d B,and operators of ultrasonic plastic welding machine operator had contacted noise intensity reaching 104. 8 d B,what's more,operators of powder machine operator had contacted noise intensity reaching 85. 2 d B,all exceeded the national occupational health standards but other operators of other working positions had contacted noise intensity met the national occupational health standards. Conclusion Occupational- disease- inductive factors are mainly caused by benzene,toluene,xylene,copper smoke,nitrogen dioxide,sodium hydroxide,potassium hydroxide and other dust( dust),welding smoke,silica dust,noise and ultraviolet radiation,and benzene,toluene,xylene silica dust and noise are considered as the key control points,so engineering protection measures and the effectiveness of individual protective measures should be taken during the working.
