BLEVE stands for

BLEVE stands for

• A. Boiling Liquid Expanding Vapor Explosion
• B. Boiling Liquid Expanding Vapor Emission
• C. Boiling Liquid Expansion Vessel Explosion
• D. Boiling Liquid Explosive Vapor Event

Answer: (A)

BLEVE describes a hazardous failure where a vessel containing pressurized, often superheated liquid ruptures and the liquid rapidly boils into expanding vapor, producing an explosion. The wording Boiling Liquid Expanding Vapor Explosion captures three essential ideas: the liquid is boiling, the vapor expands quickly, and the event is an explosion. The other options mix up these elements—emission implies release without an explosion, or uses Expansion Vessel instead of Expanding Vapor and Explosion—so they don’t convey the same dangerous mechanism. This concept is important in rescue because BLEVE can occur with tanks of propane, LPG, and other pressurized liquids, even without open flames.
