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 determine the occupational hazards and the degree of harm during the production of a medical device product and to determine the effects of occupational disease prevention facilities and occupational health management measures. Methods Data and data were collected through on-the-spot occupational health surveys, testing and testing methods, occupational health examinations and checklist methods. Occupational disease prevention facilities and individual occupational disease prevention levels were also used to evaluate the exposure level of occupational hazards among workers. Results The time-weighted concentration of total dust of the silica dust contacted by the blast furnace operator in the workshop was 1.6 mg / m 3 and the weighted concentration of dusting time was 0.3 mg / m 3, all exceeding the national health standards. After rectification, Occupational health standards, the concentration of the remaining toxic substances are in line with the requirements of national occupational health standards. The noise intensity of the contact between the cleaning room operator and the ultrasonic cleaner was 86.2 dB, the noise intensity of the contact of the ultrasonic plastic welding machine operator was 104.8 dB, the noise intensity of the contact between the powder and powder machine operators was 85.2 dB, National occupational health standards, the rest of the workers exposed to the noise intensity in line with national occupational health standards. Conclusion The main risk factors of occupational diseases are benzene, toluene, xylene, copper (by Cu), copper, nitrogen dioxide, sodium hydroxide, potassium hydroxide, other dusts (total dust), welding fumes , Noise and UV radiation. Among them, benzene, toluene, xylene, silica dust and noise are the key control points. Workers should pay attention to the engineering protection measures and the effectiveness of individual protective measures.
