What does BLEVE stand for?

• A. Boiling Liquid Exploding Vapor Event
• B. Boiling Liquid Expanding Vapor Explosion
• C. Blazing Liquid Explosive Vehicle Emission
• D. Boiling Leaking Evaporating Vapor Event

Answer: (B)

BLEVE describes a vessel failure caused by heat raising the pressure and temperature inside a container holding a liquefied gas. The liquid boils, generating a large amount of vapor that expands rapidly once the container is compromised, resulting in a powerful explosion. The wording Boiling Liquid Expanding Vapor Explosion matches this sequence: the liquid boils, the vapor expands, and the event is an explosion. The other phrasings don’t accurately reflect the process—one implies an explosion from an unstable vapor without the explicit expanding boiling liquid, another describes a different, unrelated scenario, and another substitutes a leaking or evaporating event for the explosive release.
