What does BLEVE stand for?

BLEVE stands for Boiling Liquid Expanding Vapor Explosion. This term refers to a specific type of explosion that occurs when a vessel containing a liquefied gas is exposed to heat. As the liquid inside the vessel approaches its boiling point, it can rapidly vaporize and expand. If the pressure exceeds the vessel's capability to contain it, this can lead to a violent rupture and result in an explosion as the gas rapidly escapes into the atmosphere. Understanding BLEVE is crucial for fire investigators and safety professionals, as it emphasizes the importance of controlling heat exposure to pressurized vessels containing flammable liquids. This distinction is vital for effective risk assessment and developing safety protocols, particularly in industrial settings where such materials are used.
