BLEVE stands for which phenomenon?

• A. Boiling Liquid Evaporation Vapor Explosion
• B. Boiling Liquid Expansion Vapor Explosion
• C. Boiling Liquid Expanding Vapor Event
• D. Boiling Liquid Expanding Vapor Explosion

Answer: (D)

BLEVE describes a violent failure of a pressure vessel containing hot, pressurized liquid. When heat raises the liquid to or above its boiling point under pressure, the liquid rapidly flashes to high‑pressure vapor. If the vessel ruptures, that vapor expands explosively, along with liquid fragments, producing a powerful blast. The term Boiling Liquid Expanding Vapor Explosion captures this sequence: boiling creates the vapor, the vapor expands rapidly, and the release becomes an explosion. Other options use terms that don’t describe the rapid flash and explosive energy release—such as evaporation or an event—so they don’t fit the phenomenon as accurately.
