Abstract：Large floating roof tanks usually contain a large amount of flammable liquids which can lead to catastrophes. This study analyzes accident scenarios based on 88 large external floating roof tank accident case analyses. Fire dynamics simulator (FDS) is used to compute the heat flux distribution under a rim seal fire, a full surface fire, and a bund fire. The personal vulnerability model is then used to calculate the individual risk based on the heat fluxes. The effect of wind on the risk distribution is discussed and the safety distances for firefighters are identified. The results provide useful reference for firefighting.
