What is a BLEVE?

A BLEVE, which stands for Boiling Liquid Expanding Vapor Explosion, occurs when a container holding a flammable liquid is subjected to heat, leading to a significant increase in pressure. As the temperature rises, the liquid begins to boil and expand into vapor. If the pressure reaches a point that exceeds the container's structural integrity, it can rupture explosively. This type of explosion is particularly dangerous because it can not only release the flammable liquid but also ignite the vapor, resulting in a fire or explosion.

The context surrounding BLEVE is critical in fire safety and prevention, particularly in scenarios involving pressurized vessels in industrial settings. Understanding the dynamics of heat and pressure in these situations is essential for firefighters and safety personnel to mitigate risks and respond effectively to emergencies.
