What does a BLEVE mean?

A BLEVE refers to a "Boiling Liquid Expanding Vapor Explosion." This occurs when a substance that is under pressure is heated, causing the liquid to boil and expand rapidly. When the pressure vessel contains a liquid that is heated beyond its boiling point, the vapor pressure can exceed the vessel's capacity, leading to a catastrophic failure.

In this context, understanding BLEVE is crucial for facility fire brigade members, as they must be aware of the dangers posed by high-pressure liquids and the potential for explosive events during emergencies. The other options suggest variations of explosion terminology, but they do not accurately convey the specific phenomenon associated with BLEVE. Thus, understanding BLEVE is essential for effective hazard assessment and risk management in facilities that may handle pressurized liquids.
