PEPCON wasn’t really a BLEVE, which is a Boiling Liquid Expanding Vapor Explosion. BLEVE’s are caused by pressurized vessels ( tank cars, for instance ) that fail under fire. The resulting low pressure causes the flammable liquid to immediately boil. The vapor cloud finds an ignition source and then explodes. https://www.firerescue1.com/hazards...e-train-car-explosion-bleve-Mld5gN4Nfb3zFXIT/ The military FAE, fuel air explosion, uses this principle.
