目的分析某定向结构麦秸板生产线的职业病危害因素分布及危害程度,提出相应的预防措施,预防职业病的发生。方法采用资料收集、职业卫生现场调查、工程分析和现场检测检验法对生产线进行评价。结果某定向结构麦秸板生产线主要职业病危害因素为粉尘、二苯基甲烷二异氰酸酯(MDI)、石蜡烟和噪声,该生产线工人接触粉尘、二苯基甲烷二异氰酸酯(MDI)和石蜡烟的时间加权平均浓度合格率分别为100%、67%、100%,工人接触噪声8 h等效声级计算结果合格率为11%。结论大部分工种接触噪声强度超标。建议加强工作人员的个人防护,减少工人接噪时间,减轻职业危害。
Objective To analyze the distribution and hazard of occupational hazards in a oriented structure of wheat straw board production line and put forward corresponding preventive measures to prevent the occurrence of occupational diseases. Methods Data collection, occupational health field survey, engineering analysis and on-site inspection and test method were used to evaluate the production line. Results The main occupational hazards of the oriented board production line were dust, diphenylmethane diisocyanate (MDI), paraffin smoke and noise. The production line workers were exposed to time-weighted dust, diphenylmethane diisocyanate (MDI) and paraffin smoke The average pass rate was 100%, 67%, 100% respectively. The equivalent sound level of workers’ contact noise for 8 h was 11%. Conclusion Most workers exposed to noise intensity exceeded. It is suggested to strengthen the personal protection of workers, reduce workers’ access to noise and reduce occupational hazards.
