BLEVE describes which hazard?

• A. Boiling Liquid Evaporating Vapor Emission
• B. Boiling Liquid Exposed Vapor Emission
• C. Boiling Level Expanding Vapor Explosion
• D. Boiling Liquid Expanding Vapor Explosion

Answer: (D)

BLEVE is a hazard that happens when a vessel holding a liquid at high pressure and elevated temperature ruptures, causing the liquid to flash to vapor rapidly. The rapid expansion of that vapor, combined with potential vessel fragmentation, creates a powerful explosion-like blast. The name itself—Boiling Liquid Expanding Vapor Explosion—captures this mechanism: a heated, pressurized liquid boils inside, and when the container fails, the liquid expands into a large volume of high‑pressure vapor in an instant. This is why the term describes both the boiling and the rapid vapor expansion that drives the dramatic energy release. In real scenarios, this can occur with liquids like propane or other LPGs in storage or transport tanks, where heat or damage leads to rupture and a BLEVE. The other phrased options don’t reflect the established terminology or the core mechanism of rapid vapor expansion after rupture.
