What does the acronym BLEVE stand for?

The acronym BLEVE stands for Boiling Liquid Expanding Vapor Explosion. This term describes a specific and dangerous type of explosion that can occur when a container holding a pressurized liquid (often a flammable material) is exposed to heat, leading to the liquid vaporizing rapidly. The vapor expands quickly, and if the pressure exceeds the containment capacity or if the container ruptures, it can result in a violent explosion.

Understanding BLEVE is critical for emergency responders, particularly those in hazardous materials (Hazmat) situations. Knowledge of this phenomenon helps firefighters and Hazmat operators assess risks and develop strategies to prevent explosions when handling pressurized materials. The other options listed do not accurately represent this widely recognized term in the context of fire and hazardous material safety, which contributes to the necessity of understanding the correct definition.
