What Is A
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
In conclusion it can be determined that any Company involved in the transportation of hazardous materials need to have in place an emergency response program per OSHA and DOT standards. This program along with the Safety program need to be on-going and revised. For Companies that are in the transportation of LPG's or any other pressurized products, they need to have their drivers fully aware of all possible hazards involved with the shipping and handling of the products. Drivers need to have continuing and refresher training on the aspects of the potential of fires with the tanks that could lead to a BLEVE, and to train them to be first responders of a accident seen to call for help as soon as possible and to protect the seen from the public until help arrives. From what was learned in the research above, during a potential BLEVE scenario, every second counts. The size of a BLEVE depends upon the weight of the container pieces and upon how much liquid vaporizes when the container fails. This is analogous in many respects to the performance of rockets, as far as propulsion of container parts is concerned. Most liquefied gas BLEVEs occur when containers are from slightly less than 1/2 to about 3/4 full of liquid. The liquid vaporization-expansion-energy to container-piece weight ratio is such that pieces are propelled for distances up to approximately 1/2 mile (0.8 km). Deaths from such missiles have occurred up to 800 ft (244 m) from larger containers. Fireballs several hundred feet in diameter are not uncommon, and deaths from burns have occurred to persons as much as 250 ft (76 m) from the larger containers. The time between initiation of flame contact and a BLEVE varies because it depends upon such widely varying factors as the size and nature of the fire as well as the container itself and any damage dome to the tank. Uninsulated containers located aboveground, such as the type that are transported by tanker trucks, can BLEVE in the absence of water cooling in a matter of a very few minutes. the liquid to be flammable to have a BLEVE occur. Liquefied petroleum gas (LPG) is particularly exposed to the risk of serious accidents such
