Dangerous area prediction and emergency disposal of liquid ammonia leakage accident

摘要

The leakage accident of liquid ammonia has a strong toxicity and the potential explosively, the models of ammonia which are diffusion, shock-blast wave, thermal radiation etc are established by setting parameters of ammonia, such as pernicious dose, explosive power, injury rank etc, these can be helpful to forecast the dangerous areas of toxic risk, explosion hazard, radiation hazard etc. By delimiting dangerous areas of liquid ammonia leakage accident, fire brigade can scientifically build the rescue areas and reduce the rescue time, these will provide scientific guidance for evacuation personnel and determent leakage.
