Abstract: A method and system for predicting a diffusion range of a hazardous gas, an electronic device and a storage medium are provided. The method includes: gridding a space area of a public scene to obtain a gridded space; performing leakage source analysis according to the gridded space to determine a leakage feature; determining a hazardous gas prediction manner according to the leakage feature and an early warning condition, where the hazardous gas prediction manner includes a hazardous gas existence mode and a protective gas coexistence mode; determining a diffusion circle coverage according to the hazardous gas prediction manner and a wall barrier action; determining a hazardous gas concentration in grids covered by a diffusion circle according to the diffusion circle coverage; and determining a hazardous gas distribution according to the hazardous gas concentration, a leakage outlet and a ventilation opening.
