Abstract：Tobetterquantifythediffusionlawandrisk impactrangeofleakage，aliquidammoniapipelineleakageacident model was constructed based on ALOHA software.Setuppipeline rupture scenariosusing ALOHA software，input liquid ammonia physical parameters and meteorological data，simulate the dynamic distribution of toxicgas clouds using a heavygasdifusionmodel，andanalyzetheexposureareaandsecondarydisasterriskundertheconcentrationthresholdof Immediate Dangerous to Lifeor Healthconcentration （IDLH）.The simulationresults indicate thatthe impactradius can reach 300m within 3O minafterthe leak，and there isasignificant exposure risk indensely populated areas.Based onthis， a graded emergencyresponse strategy such as dynamicalertzone divisionand medicalresource pre setting is proposed to provide decision support for the prevention and control of hazardous chemical accidents.
