A fleet transportation company that is involved in the transportation of hazardous materials, such as LPG's (liquid petroleum gases), needs to have the knowledge and training provided for their drivers in the Company's safety program for emergency response and driver awareness, when involved in the transportation of this type of products over the highways. Due to the violent reactions and circumstances if there is an accident involving a tanker truck transporting LPG's, and a fire is involved, every second will count to avoid a potentially fatal situation. The driver if not seriously injured and properly trained can help avoid the loss of life and property when becoming a first responder during an accident involving tankers transporting LPG 's.
             Boiling-Liquid-Expanding-Vapor Explosion (BLEVE): A type of rapid phase transition in which a liquid contained above its atmospheric boiling point is rapidly depressurized, causing a nearly instantaneous transition from liquid to vapor with a corresponding energy release. A BLEVE is often accompanied by a large fireball if a flammable liquid is involved, since an external fire impinging on the vapor space of a pressure vessel is a common BLEVE scenario. However, it is not necessary for the liquid to be flammable to have a BLEVE occur. Liquefied petroleum gas (LPG) is particularly exposed to the risk of serious accidents such as BLEVE (Boiling Liquid Expanding Vapor Explosion), i.e. explosion of a tank due to rapid evaporation of the liquid contained caused either by a depressurization wave generated by a hole accidentally formed in the tank shell or by an intense heat radiation load due to an external fire. As a consequence of the tank failure, the tank is flattened to the ground, giving rise to a strong blast wave, a destructive fireball, and in some cases the formation of numerous fragments that can be propelled significant distances. The characteristic time duration...
