不同浓度硝酸水溶液的氧化性和火灾危险性分类探究

Classification of oxidability and fire hazards of aqueous nitric acid solution of different concentrations

我国《建筑设计防火规范》中关于硝酸火灾危险性类别的划分较为笼统,不能适应生产、储存、经营或使用不同浓度硝酸水溶液的要求,针对该问题,介绍了国内外相关法规和标准规范关于不同浓度硝酸水溶液的氧化性分类和危险分级情况,并对不同浓度的硝酸水溶液从储存、生产、使用等方面提出新的火灾危险性分类建议。

The classification of nitric acid fire hazards in the national standard Code for Fire Protection Design of Buildings was relatively simple and general,which could not meet the requirements of production,storage,operation or use of aqueous nitric acid solution of different concentrations.In view of this problem,the oxidability and fire hazards classifications of different concentrations of aqueous nitric acid solution in both domestic and foreign relevant codes and standards were introduced.Accordingly,suggestions of new fire hazards classification were put forward for aqueous nitric acid solution of different concentrations from the aspects of storage,production,use,etc.
