BLEVE hazard relates to which phenomenon?

• A. Corrosion
• B. Dust explosion
• C. Boiling Liquid Expanding Vapor Explosion in pressurized containers
• D. Radiation

Answer: (C)

BLEVE hazard is the boiling liquid expanding vapor explosion in a pressurized container. When a vessel holding a volatile liquid under pressure is heated or damaged, the liquid inside is at high temperature and pressure. If the container ruptures, the pressure drop causes the hot liquid to flash to vapor almost instantly. The rapidly expanding vapor creates a powerful explosion and can shatter the container. This is a concern with LPG, propane, and similar pressurized liquid fuels. It isn’t about corrosion, a dust explosion, or radiation, which involve different mechanisms.
