某包覆工艺板式家具生产项目职业病危害控制效果评价

目的对某包覆工艺板式家具生产项目进行职业病危害控制效果评价。方法采用现场调查法、检查表法与检测检验法对该建设项目进行评价,确定其主要的职业病危害因素及危害程度,评价相应防护措施的效果。结果断车、锯床、双端锯、电子锯、多片锯岗位的噪声强度超过国家卫生限值。整改前,包覆机的二氯甲烷时间加权平均浓度（TWA）最大值为527.1 mg/m^3,超标1.64倍;1,2-二氯乙烷时间加权平均浓度（TWA）最大值22.7 mg/m^3,超标2.24倍。整改后,二氯甲烷和1,2-二氯乙烷的TWA分别下降到〈11 mg/m^3和6.9 mg/m^3,均符合国家卫生标准。其他各检测点的职业病危害因素浓度或强度均符合国家规定的卫生限值。结论该建设项目职业卫生防护措施符合国家职业卫生标准,产生的职业病危害因素是可以预防和控制的。

Control Effect of Occupational Hazard in Construction Project of Covering Technologic Furniture

Objective To evaluate control effect of occupational hazards in the construction project of covering technologic furniture. Methods According to national standards, occupational hazards of the project were evaluated by the methods of investigation, check lists and monitoring to confirm occupational risk factors and the level, and to evaluate the effects of preventive measures. Results Noises of cutter, sawmill,double - saw, electronic - saw and multi - saw posts exceeded the limit of national standards. Before reformation for covering machine post, the maximum value of time weighted average （TWA） of Dichloromethane and 1,2-Dichloroethane were 527. 1 mg/m^3 and 22. 7 mg/m^3 ,exceeding the standard by 1.64 times and 2. 24 times, respectively. After reformation, TWA of Diehloromethane and 1,2-Dichloroethane decreased to 〈 11 mg/m^3 and 6.9 mg/m^3 respectively, which both accorded with national standards. The other occupational risk factors met national standards. Conclusion The occupational preventive measures accord with the requirements of national occupational health standards, the occupational hazards can be prevented and controlled.
