HoweverBoiling liquid expanding vapor explosion - WikipediaA boiling liquid expanding vapor explosion (BLEVE, / b l v i / BLEV-ee) is an explosion caused by the rupture of a vessel containing a pressurized liquid that has reached temperatures above its boiling point. Because the boiling point of a liquid rises with pressure, the contents of the pressurized vessel can remain liquid so long as the vessel is intact.
