ALOHA软件在化学应急救援中的应用

Application of ALOHA software in chemical emergency rescue

  • 摘要: 介绍了ALOHA软件中化学事故危害分级的标准和软件的操作流程,并分别通过预设甲苯、液氯泄漏,分析了软件对事故后果的计算结果,得出了甲苯在设定条件下的蒸气云爆炸可能性、储罐爆炸(boiled liquid evaporate vapor explosion,BLEVE)的危害范围、毒性危害范围;也表明了液氯在设定条件下、距离泄漏源不同距离处对人体的危险性。表明可以根据ALOHA软件模拟的毒物泄漏危害范围,组织群众撤离危害区域;也可以通过ALOHA软件的计算结果,为应急分队制定化学应急救援预案以及事故现场处置辅助决策提供依据。

     

    Abstract: This paper introduced the classification standards of chemical accident hazards used in ALOHA(areal locations of hazardous atmospheres)software and the use guideline of this software. Taking example of leakage of toluene and liquid chlorine, the calculation results for the accident consequences using this software were present. The results showed that the possibility of vapor cloud explosion, the scope of damage and toxicity of boiled liquid evaporate vapor explosion (BLEVE) when toluene leakage occurred under certain conditions. The danger of liquid chlorine to human body under certain conditions and at different distances from the leakage source was also clearly shown. We can organize people to evacuate the hazard area according to the scope of toxic leakage hazard simulated by ALOHA software, while we make the chemical emergency rescue plan and site decision-making for the emergency response team based the calculation results of ALOHA software.
