Abstract This study describes the use of fault tree analysis to determine the possible routes to a Boiling Liquid Expanding Vapour Explosion (BLEVE) in a spherical butane storage vessel. The dominant event was shown to be a severe earthquake occurring with sufficient strength to sever the 14 inch pipe connected to the bottom of the sphere. The study concludes that the hardware associated with the sphere is adequate to ensure that the frequence of a BLEVE is very low. The general technique used in the study is suitable for application to other LPG storage spheres.
