Study on Explosion Safety Distance in LPG Tank Fire

According to the hazardous characteristics of LPG storage tanks and their types and hazards of fire and explosion accidents, the impact evaluation method, the shock wave overpressure criterion and the heat flux criterion are applied to the standard of human injury. Fire shock wave and heat radiation generated by three different accident types were calculated. The quantitative estimation model of safety distance and LPG reserves was studied, which provided a supplementary basis for the personnel evacuation and firefighter command and decision on LPG fire scene.
