目的通过了解噪声作业人员个体防护设备的使用及认知情况,找出问题,为今后制定防护对策提供可靠的依据。方法以宜兴市2家噪声危害比较严重的机械制造企业作为调查对象,2011年9月通过问卷和现场调查获得个人防护用品使用情况及噪声防护的认知情况;用国产HS6288B噪声频谱分析仪检测车间噪声;噪声性耳聋由具有诊断资质机构的医师集体依据GBZ 49-2007《职业性噪声聋诊断标准》进行诊断。结果 9个车间中4个车间的噪声超过85 dB(A),最高达92.1 dB(A);听力检查发现有高频听力损失者34人,检出率为14.8%,发现噪声聋患者7人,检出率为3.0%;2个企业的噪声接触人员耳塞佩戴培训率为66.1%,参加噪声危害教育率比较低,为42.2%;全程佩戴耳塞的人员为67.8%,能够完全正确佩戴耳塞的人员仅占18.7%,不戴耳塞的主要原因是与人交流不方便,占48.9%;噪声危害的知晓率为71.7%;正确使用防护用品的知晓率为63.0%。结论企业需要采取综合性的措施提高噪声作业人员耳塞的正确佩戴率,才能达到保护作业人员健康的目的。 Objective To understand the use and cognition of noise protective equipment for personal protective equipment and identify problems so as to provide a reliable basis for formulating protective measures in the future. Methods Two mechanical manufacturing enterprises with more serious noise hazards in Yixing City were investigated. In September 2011, questionnaires and field surveys were used to obtain personal protective equipment (PPE) and noise awareness. The domestic HS6288B noise spectrum analyzer was used to test the workshop Noise; Noise deafness by the diagnosis of qualified physicians collectively based on GBZ 49-2007 “diagnostic criteria for occupational noise deafness” for diagnosis. Results The noise of more than 85 dB (A) and the highest of 92.1 dB (A) were found in 4 of the 9 workshops. Among the hearing tests, 34 were found to have high-frequency hearing loss with a detection rate of 14.8% , And the detection rate was 3.0%. The training rate of earplugs for noise exposure was 66.1% in 2 enterprises and 42.2% in noise hazard. The total wearing of earplugs was 67.8%, and the earplugs Only 18.7% of the staffs did not wear earplugs. The main reason for not wearing earplugs was that it was inconvenient to communicate with people, accounting for 48.9%; the awareness of noise hazards was 71.7%; and the awareness rate of using protective equipment correctly was 63.0%. Conclusion Enterprises need to take comprehensive measures to improve the correct wear rate of noise workers earplugs, in order to achieve the purpose of protecting the health of workers.
