目的了解某粮油加工企业生产过程中存在的职业病危害因素及其控制措施,为职业病防护提供科学依据。方法采用现场职业卫生调查、职业卫生检测和职业健康检查法对职业病危害进行调查分析。结果该企业生产过程中产生的主要职业病危害因素为正己烷、石蜡烟、噪声、谷物粉尘和高温。现场检测结果显示各车间岗位接触化学物浓度和高温强度均符合国家职业接触限值的要求,但豆粕包装车间工人接触谷物粉尘浓度、预处理车间巡检岗位和车间控制室噪声强度均超过国家标准,且近3年预处理车间巡检岗有3例检出纯音听阈测试高频段双耳平均听阈>40 d B。结论粮油加工企业噪声和粉尘危害不容忽视,应采取切实可行的防护设施和措施,保护劳动者的健康。
Objective To understand the hazards and control measures of occupational diseases in the process of a grain and oil processing enterprise and provide a scientific basis for the protection of occupational diseases. Methods Investigation and analysis of occupational hazards were conducted by field occupational health survey, occupational health examination and occupational health examination. Results The main occupational hazards in the production process were n-hexane, paraffin, noise, grain dust and high temperature. The field test results showed that the contact chemical concentration and high temperature strength of all the workshops met the requirements of the national occupational exposure limits. However, the soybean meal packaging workshop workers exposed to the grain dust concentration, the pretreatment workshop inspection positions and the workshop control room noise intensity surpass the national standard , And nearly 3 years pretreatment workshop inspection post 3 cases detected pure tone hearing threshold test high frequency binaural hearing threshold> 40 d B. Conclusion The noise and dust hazards of grain and oil processing enterprises should not be neglected. Practical protective facilities and measures should be taken to protect the health of workers.
