摘　　要：目的了解广州市某聚碳酸酯薄膜制造项目存在的职业病危害因素及其危害程度,为职业病危害防治提供依据。方法2019年7月,采用职业卫生现场调查、职业病危害因素检测和职业健康监护等方法,对广州市某聚碳酯薄膜制造项目生产线职业病危害因素和危害程度进行识别及分析。结果广州市某聚碳酸酯薄膜项目存在的职业病危害因素有噪声、高温、电离辐射、苯酚、甲基丙烯酸甲酯、三氯乙烯、二甲苯、甲苯、丙酮及乙酸丁酯。作业人员40 h等效声级结果为76.2~81.2 dB(A),时间加权平均综合温度指数(wet bulb globe thermometer,WBGT)为25.9~29.0℃,电离辐射年受照剂量最大为0.168 mSv,苯酚、三氯乙烯的8 h加权平均浓度分别为0.09和0.27 mg/m^(3),甲基丙烯酸甲酯、二甲苯、甲苯、丙酮、乙酸丁酯均未检出。以上职业病危害因素的浓度或强度均符合国家规定的职业接触限值,但在个人剂量计、职业健康监护等管理方面存在不足。结论广州市某聚碳酸酯薄膜项目的职业病危害防治关键控制因素是三氯乙烯和电离辐射,应加强化学品采购及职业卫生管理工作。Objective To understand the occupational hazard factors and hazard degree of a polycarbonate film manufacturing project in Guangzhou,so as to provide basis for the prevention and control of occupational hazards.Methods In July 2019,the occupational hazard factors and hazard degree of the production line were identified and analyzed by means of on-site investigation of occupational health,detection of occupational hazard factors and occupational health monitoring.Results The occupational hazard factors of a polycarbonate film project in Guangzhou included noise,high temperature,ionizing radiation,phenol,methyl methacrylate,trichloroethylene,xylene,toluene,acetone and butyl acetate.The 40 h equivalent sound level results of operators were 76.2-81.2 dB(A),the time weighted average comprehensive temperature index(WBGT)was 25.9-29.0℃,the maximum annual exposure dose of ionizing radiation was 0.168 mSv,the 8 h weighted average concentrations of phenol and trichloroethylene were 0.09 and 0.27 mg/m^(3) respectively,and methyl methacrylate,xylene,toluene,acetone and butyl acetate were not detected.The concentration or intensity of the above occupational hazard factors met the occupational exposure limits specified by the state,but there were deficiencies in the management of personal dosimeter and occupational health monitoring.Conclusion Trichloroethylene and ionizing radiation are the key control factors for the prevention and control of occupational hazards of a polycarbonate film project in Guangzhou.Chemical procurement and occupational health management should be strengthened.
