某胶状乳化炸药生产线职业病危害预评价

目的分析某胶状乳化炸药生产线建设项目可能产生的职业病危害因素及危害程度,对劳动者健康的影响、防护措施等进行预评价。方法采用类比法对本项目可能产生的职业病危害因素种类和强度进行定性、定量分析。结果类比项目存在的职业病危害因素苯、甲苯、二甲苯未检出,氨STEL和TWA分别是0.43～13.98mg/m^3、0.75～10.10mg/m^3,氮氧化物、噪声、高温、粉尘均符合国家职业接触限值。结论该项目属于严重职业病危害项目,项目建成后只要认真落实拟采取的职业病危害防护措施和补充措施则可以满足职业卫生要求。

Pre-Assessment of Occupational Hazards in Production Line of Colloid Emulsified Explosive

Objective To analyze occupational hazard factors possibly existed in the production line of colloid emulsified explosive,and evaluate hazard level,impact on workers’ health and protective measures of the construction project.Methods The method of analogy was used for qualitative and quantitative analysis of occupational hazard factors.Results Benzene,toluene and xylene weren’t found in the analogical project,the values of STELs and TWAs for ammonia were 0.43-13.98 mg/m^3 and 0.75-10.10 mg/m^3,values of NOx,noise,high temperature and dust were under occupational exposure limits.Conclusion It is a serious construction project. Planned occupational protective measures and additional measures will satisfy occupational requirements.
