BLEVE stands for Boiling Liquid expanding Vapour Explosion. It's what you get when you heat up, say, a Propane Tank Car until the liquid propane boils off enough vapour for an explosion. I've been present when a 1/3 section of railroad tank car sailed more than a thousand feet toward me. I don't think a hot water tank will do that but boilers can, and plumbers obviously need to be properly trained. -- Bob Smits [EMAIL PROTECTED] A: Because it messes up the order in which people normally read text.
