目的了解玉米深加工生产企业作业场所职业病危害因素种类、工人接触水平及玉米深加工生产企业存在的职业卫生问题。方法对生产企业职业病危害控制效果评价报告进行分析。采取现场职业卫生学调查,根据国家现行职业卫生标准进行职业病危害因素检测。结果粉尘个体采样测试结果均未超过国家卫生限值的要求,合格率为100%,粉尘定点测试短时间接触浓度合格率为90.91%。所测有毒物质均未超标,所评价毒物作业岗位均合格,以玉米深加工企业较完善的设备维护制度以及所采取的通风防毒措施能满足控制有毒物质危害的效果。结论玉米深加工企业高噪声生产设备较多,加之因工艺要求多为集中布置,造成噪声叠加,工人多为固定岗位作业,接触时间长,对工人健康有一定影响,建议加强个人防护用品的使用。
Objective To understand the types of occupational hazards in workplaces, the level of workers' exposure and the occupational health problems in corn deep-processing manufacturing enterprises. Methods The evaluation report on the control effect of occupational hazards in manufacturing enterprises was analyzed. Take on-site occupational hygiene survey, according to the current national occupational health standards for occupational hazards detection. Results The individual dust sampling results did not exceed the national health limit requirements, the pass rate was 100%, dust fixed-point test of short-term exposure concentration of 90.91% pass rate. The measured toxic substances are not exceeded, the evaluation of toxic jobs are qualified to better corn deep processing equipment maintenance system and the adoption of ventilation and anti-virus measures to meet the toxic effects of the control of toxic effects. Conclusion There are more high-noise production equipment in corn deep-processing enterprises. In addition, the noise concentration is mostly due to the concentration of noise and noise. The workers often work in fixed positions and have long exposure time, which may affect workers' health. Therefore, it is suggested to enhance the use of personal protective equipment.
