What does BLEVE stand for?

• A. Boiling Liquid Expanding Vapor Explosion
• B. Boiling Liquid Evaporating Vapor Emulsion
• C. Breathing Liquid Expanding Vapor Explosion
• D. Burning Liquid Expanding Vapor Explosion

Answer: (A)

BLEVE stands for Boiling Liquid Expanding Vapor Explosion. It describes a situation where heat raises a liquid in a sealed, pressurized vessel to its boiling point; the liquid boils and builds up very high-pressure vapor. If the vessel ruptures, this superheated liquid rapidly flashes to vapor and expands, blasting the container apart and producing a powerful explosion. This hazard is common with liquefied gases stored under pressure, like propane or LPG. The other phrases don’t fit the real mechanism—the event is defined by boiling, rapid vapor expansion, and resulting explosion, not breathing, burning, or emulsions.
