BLEVE is the acronym for which phrase?

• A. Boiling Liquid Evaporating Vapor Explosion
• B. Boiling Liquid Expanding Vapor Event
• C. Boiling Liquid Explosive Vapor Eruption
• D. Boiling Liquid Expanding Vapor Explosion

Answer: (D)

BLEVE describes a vessel failure where a liquid under pressure is heated enough to boil, and when the container fails, the liquid flashes to vapor and expands rapidly, producing a violent pressure release. The phrase that matches this mechanism is Boiling Liquid Expanding Vapor Explosion. Here, Boiling signals that the liquid is at or above its boiling point, Expanding highlights the rapid rise in vapor volume, Vapor is the gaseous phase formed, and Explosion conveys the sudden, high-energy blast that can result. Other phrasings use terms like Event or Eruption or swap Explosion for a different word, but they don’t align with the standard description of this phenomenon.
