目的摸清电子产品生产线生产环境中职业病危害因素存在种类、分布、状态、危害程度、劳动者接触水平等并做出综合评价,对可能造成损害劳动者健康的环节提出防护措施。方法采用现场劳动卫生调查、现场职业病危害因素检测、实验室检验等方法。结果电子产品生产过程中主要产生的职业病危害因素铝尘、铜尘、二氧化锡、铅烟、苯、二甲苯、丙酮、正己烷等的时间加权平均浓度均符合国家职业接触限值的要求。移印工、目检工、油墨分装工、调油墨工接触甲苯的时间加权平均浓度432 mg/m3和移印机、目检区、油墨分装间、调油墨区岗位空气中甲苯的短时间接触浓度143 mg/m3不符合职业接触限值。激光辐射强度、高温WBGT指数、照度均符合职业接触限值的要求;噪声除自动钻孔工96(dB(A)、点检工88(dB(A)和成型工90(dB(A)等效声级超过职业接触限值。结论甲苯、噪声超标,经综合分析,判定电子产品生产线职业病危害风险类别为“职业病危害严重”。应加强相关防护措施进行预防,防止职业病中毒及相关疾病发生。
Objective To find out the types, distribution, status, degree of harm, the level of workers’ exposure, and other comprehensive evaluation of occupational hazards in the production environment of electronic product lines and to make a comprehensive evaluation of the factors that may cause harm to the health of workers. Methods: On-the-spot labor health survey, field occupational disease risk factors testing, laboratory tests and other methods. Results The main risk factors of occupational diseases in the production of electronic products were time-weighted average concentrations of aluminum dust, copper dust, tin dioxide, lead smoke, benzene, xylene, acetone and n-hexane, which all met the requirements of the national occupational exposure limits. The time-weighted mean concentration of toluene, toluene, migrating workers, head inspectors, ink dispensers and ink transfer workers was 432 mg / m3 and the shortening of toluene in the air of the printing machine, visual inspection area, ink dispensing room and ink adjusting area Time exposure concentration 143 mg / m3 Non-observance of occupational exposure limits. The laser radiation intensity, high temperature WBGT index and illuminance all meet the requirements of occupational exposure limits. Noise In addition to the automatic boring workers 96 (dB (A), 88 (dB (A)) and forming workers 90 The sound level exceeds the occupational exposure limit.Conclusion Toluene and noise exceed the standard, after a comprehensive analysis, to determine the risk of occupational hazards in the electronics product line as “serious occupational hazards.” Prevention should be strengthened to prevent occupational diseases and related diseases occur.
