What are the main hazards of an LPG Bleve?

The main hazards associated with a Liquefied Petroleum Gas (LPG) Boiling Liquid Expanding Vapor Explosion (BLEVE) primarily involve fire, thermal radiation, blast effects, and projectiles.

In the case of a BLEVE, if a storage tank filled with liquid LPG is subjected to external heat, the liquid inside can violently vaporize and expand. This rapid expansion can cause the tank to rupture, leading to a fireball as the escaping gas ignites. The thermal radiation from this fire can pose significant risks to people and structures in the vicinity.

Moreover, the explosion can generate a blast wave that propagates outward, causing damage to nearby structures and potentially injuring individuals in the area. The ruptured tank can become a shrapnel projectile, further increasing the risk of injury or damage to surroundings.

While the other options mention various hazards, they do not specifically address the unique and immediate dangers presented by a BLEVE involving LPG. For example, flooding and erosion are not relevant in the context of a BLEVE, nor are contamination and smoke, which are more associated with chemical spills rather than the specific combustion and explosion risks of LPG. Inhalation and skin irritation relate to toxic substances but do not capture the explosive and incendiary
