Impact of Wildfires on LPG Tanks

Abstract

During wildland fires, wildland-urban interfaces may cause significant problems for emergency managers throughout the world. Several works focused on safety zones aiming to prevent houses to burn, but no work focused on the LPG tanks which can be located in the surroundings of houses. A finite elements modelling was developed to calculate safety distance preventing from BLEVE. The safety distances required by law in several countries (50 m; 30 m; 25 m) are checked. It appears that the required safety distances are correct to prevent the tank from BLEVE.
