BLEVE is boiling liquid expanding vapor explosion. BLEVE is caused during fire of a tank, drum or any storage of liquids or gas when the container gives up due to pressure above its boiling point.

BLEVE is a great danger for fire fighters and those near. The first time this term was used after the Kansas City incident.

In Emergency Response Procedures for Ships Carrying Dangerous Goods  (EmS Guide) Below Schedules warns about BLEVE

F – C : NON-FLAMMABLE GASES

Gases in closed tanks exposed to heat may explode suddenly in or after a fire situation by a Boiling Liquid-Expanding Vapour Explosion (BLEVE). Heated or ruptured cylinders may rocket.

F – D : FLAMMABLE GASES

Gases in closed tanks exposed to heat may explode suddenly in or after a fire situation by a Boiling Liquid-Expanding Vapour Explosion (BLEVE).  Crew members should be aware of the explosion hazard and take appropriate action.

F – E : NON-WATER REACTIVE FLAMMABLE LIQUIDS

Cargoes in tanks exposed to heat may explode suddenly in or after a fire situation by a Boiling Liquid-Expanding Vapour Explosion (BLEVE). Keep tanks cool with copious quantities of water.
