目的掌握无锡市某太阳能电力制造工程中职业病危害因素的发生规律和分布特点,为制定防治相应职业病对策提供依据。方法对该公司在生产过程中产生的主要职业病危害因素进行识别,分析工人体检资料。结果工作场所空气中HCl、HF多数指标的合格率均为100%;部分工序中,制绒的异丙醇,PEVCD中的噪声,丝网印刷中的环氧乙烷,手工焊中的铅烟、异丙醇,均超过职业限值。接触铅烟的职工尿常规、血压、生化检验、B超异常检出率不同性别之间的差异有统计学意义(P<0.05)。结论化学毒物与噪声是该公司的主要职业病危害因素,应加强职业卫生管理,制订应急救援预案,落实日常检查和员工培训,有效控制职业病危害。

Objective To know about the regularity and distribution characteristics of hazard factors of occupational disease in a solar energy manufacturer in Wuxi City, and provide basis for occupational disease control and prevention. Methods The major risk factors produced in the process of solar energy manufacturing were recognized and analyzed; combination with workers＇ medical examination material. Results In the air of workplace, indicators like HC1 and HF were all met the standard with 100~/00, however, the material produced in the production process were above the occupational exposure limits, such as i- sopropyl alcohol of ZhiRong, noise of PECVD, epoxy ethane of screen printing and the lead smoke and isopropyl of hand weld- ing. Abnormal detection rate of urinalysis, blood pressure, biochemical examinations and B ultrasound had significant statisti- cal differenees（P〈0.05）in gender. Conclusion Overall, the chemical poisons and noise were the main occupational hazards in the company, steps such as strengthening the occupational health management, formulating emergency plan, carrying out daily inspection and on-the-job training should be enhanced to control occupational disease hazards effectively.
