THE PHYSICS OF A FIREBALL: THE BLEVE 💥 What you see in this video is a BLEVE (Boiling Liquid Expanding Vapor Explosion) involving an LPG truck. It is one of the most feared events in process engineering. ⚙️ How it Happens: Pressurization: A liquid (like propane) is kept under high pressure in a sealed tank, allowing it to stay liquid even above its boiling point. Structural Failure: Usually caused by external fire, the tank metal weakens and eventually tears. Instant Vaporization: When the tank

A BLEVE (Boiling Liquid Expanding Vapor Explosion) is a major accident hazard in process safety. It happens when a vessel containing a liquid at a temperature well above its normal boiling point suddenly fails (usually due to fire impingement, overpressure, or material failure). What is BLEVE? Definition: The explosive release of pressurized liquid and vapor when a vessel ruptures. Cause: Rapid vaporization of the liquid due to sudden pressure loss, producing a violent blast and fireball if the
