What does BLEVE stand for?

• A. Boiling Liquid Expanding Vapor Explosion
• B. Burning Liquid Expanding Vapor Emission
• C. Boiling Liquid Evaporation Vapor Emission
• D. Boiling Liquid Expanding Vapor Emission

Answer: (A)

BLEVE stands for Boiling Liquid Expanding Vapor Explosion. This term describes a specific failure and release scenario for a vessel containing a pressurized liquid: when exposed to heat, the liquid inside starts to boil and generate a large volume of highly pressurized vapor. If the vessel ruptures or fails, the stored liquid rapidly flashes to vapor and expands explosively, producing a powerful blast and often projecting vessel fragments. The key ideas are boiling liquid, expanding vapor, and the resulting explosion. The other phrases don’t fit because they either replace the final outcome with emission or evaporation, which describe vapor release without the explosive force, or they change the action from explosion to a less dramatic release. The defining feature of a BLEVE is the explosive rupture accompanied by a rapid expansion of vapor.
