广西现代水泥生产企业噪声危害调查与分析

Noise Hazards in Modern Cement Enterprises in Guangxi

  • 摘要: 目的 了解广西现代水泥生产企业噪声危害状况, 为企业噪声职业病危害防治提供依据。

    方法 于2010-2012 年对广西6 家新型干法旋窑水泥生产企业进行了调查。用现场职业卫生学调查、工作场所噪声检测、个人剂量计8 h 等效声级检测、噪声作业分级和纯音听力测定相结合的方法进行分析。

    结果 18 个接噪工种个人8 h 等效声级为61.7~98.6 dB(A), 工种超标率为33.3%~44.4%, 超标工种噪声作业分级达到中度危害者占25.0%~37.5%、重度危害者占0.0%~16.7%。企业在投产4~7 年、工人接噪工龄1~7 年的情况下, 接噪工人听力损失检出率达12.9%~17.0%, 其中高频听力损失检出率为10.8%~15.8%, 轻度噪声聋检出率为1.2%~2.4%。

    结论 广西现代水泥生产企业噪声职业危害仍不容忽视。在现有工艺技术条件下, 应加强噪声危害的个人防护。

     

    Abstract: Objective To explore noise hazards in modern cement enterprises in Guangxi, and to provide reference for protective and control measures against occupational noise.

    Methods From 2010 to 2012, 6 cement production enterprises with new type dry process rotary kiln in Guangxi were enrolled. A field occupational health investigation was conducted to measure noise levels in selected workplaces, 8-hour equivalent noise levels, classifications of tasks exposed to noise, and workers' electronic audiometry.

    Results The 8-hour equivalent noise level of 18 types of tasks that were exposed to noise were 61.7-98.6 dB(A), and the exceeding rates were 33.3%-44.4%. The classifications of tasks exposed to noise were 25.0%-37.5% as moderate hazards and 0.0%-16.7% as severe hazards. Of the workers with 1-7 years of noise exposure and in the cement enterprises that had operated for 4-7 years, the prevalence of hearing loss ranged from 12.9% to 17.0%, among which the detection rates of high-frequency hearing loss were 10.8%-15.8% and those of mild noise-induced deafness were 1.2%-2.4%.

    Conclusion More attention should be paid to the occupational noise detected in the modern cement enterprises in Guangxi. It is necessary to strengthen individual protection against noise hazards under current production technology.
