What does the acronym BLEVE stand for in the context of hazardous materials?

The acronym BLEVE stands for Boiling Liquid Expanding Vapor Explosion. This term is specifically used in the context of hazardous materials to describe a scenario where a vessel containing a liquefied gas is subjected to heat, causing the liquid to boil and generate vapor. As pressure builds within the vessel, if it exceeds the vessel’s ability to contain it, a catastrophic failure can occur, resulting in an explosion. This type of incident is particularly dangerous because it can create a fireball and release a large quantity of hazardous materials into the environment.

Understanding BLEVE is crucial for emergency responders and hazardous materials handlers, as it emphasizes the importance of controlling heat exposure to pressurized vessels and highlights the potential consequences of neglecting safety measures around these types of substances.
