When LPG tanks are exposed to fire, they will fail in different mode. And the failure mode determines whether catastrophic boiling liquid expanding vapor explosion (BLEVE) take place. The objective of this work is to develop a correlation between the failure severity and the tank condition at failure. In this paper, the process and mode of fire-induced failure of LPG tanks was analyzed. And three failure modes of short-duration BLEVE, long-duration BLEVE, and jet release were presented, for each failure mode, the preconditions and key factors were analyzed. At last, a BLEVE accident was analyzed. In short-duration BLEVE, the vapor energy will play an important role in determining whether a BLEVE takes place. In long-duration BLEVE, the liquid energy will play a major role.
