What caused the San Juanico disaster?

What caused the San Juanico disaster?

The disaster started due to LPG leakage, probably a pipe leakage or rupture due to excess pressure. A vapour cloud built up and was slowly moved by the north-east wind towards the ground-placed flare pit located in the western part of the plant.

What happened in San Juanico?

In the San Juanico Disaster, six of these spherical type liquid petroleum gas (LPG) containers exploded into huge fireballs killing 500–600 people and causing severe burns in 5000–7000 others.

What is a Bleve fire?

A BLEVE occurs when a vessel containing liquid above its normal boiling point and under pressure fails catastrophically. A vessel exposed to external fire may fail below its design pressure, resulting in a BLEVE, if the vapor space of the vessel is exposed to flames.

What are the signs of a Bleve?

BLEVE Warning Signs:

  • Ringing sound from the metal shell.
  • discolouration of the tank structure.
  • Flaking of small metal pieces.
  • Bubble or bulge on the tank surface.
  • A sudden increase in the tank pressure.

What does Bleve mean?

Boiling Liquid Expanding Vapor Explosion
Boiling Liquid Expanding Vapor Explosion (BLEVE) The failure of a closed container as a result of overpressurization caused by an external heat source. A major failure of a closed liquid container into two or more pieces when the temperature of the liquid is well above its boiling point at normal atmospheric pressure.

How do you control BLEVE?

Firefighter safety in BLEVE-possible situations

  1. Keep as much distance from the fire as possible by using unmanned hose holders or monitor nozzles.
  2. Flood containers with large quantities of water to cool them until well after the fire is out.
  3. Avoid icing by not directing water at the source of a leak.

What causes BLEVE?

A BLEVE occurs when a vessel containing liquid above its normal boiling point and under pressure fails catastrophically. The damage is caused by the pressure wave from rapid expansion of the released vapor, and from flying pieces of the vessel and piping.
