BLEVE stands for which phrase?

• A. Boiling Liquid Expanding Vapor Emission
• B. Boiling Liquid Expanding Vapor Explosion
• C. Boiling Liquid Evaporation and Vaporization Effect
• D. Basic Level of Explosive Vapor Emission

Answer: (B)

BLEVE stands for Boiling Liquid Expanding Vapor Explosion. This hazard happens when a container holding a liquid under pressure is heated (such as by a nearby fire). The liquid reaches its boiling point and rapidly turns into high-pressure vapor. That vapor expands explosively, and if the vessel ruptures, the energy is released violently as an explosion. The term emphasizes both the rapid boiling and the explosive release of energy, not just a passive emission or evaporation. In practice, flammable liquids stored under pressure, like propane or other LPG products, pose BLEVE risk because heat can cause boiling and rapid vapor expansion, followed by a catastrophic rupture.
