Paraphrasing 2 - Essay Example A leak was identified and endeavors to correct the defect by striking the fitting with a large wrench triggered the gas to ignite, which turned the tank car into a blowtorch. Processes that are linked to BLEVE include heat transfer (from flame to tank, between liquids and vapor phases, and from tank walls to the liquid and vapor stages, thermodynamic changes within the tank linked with pressure buildup, tank failure, material property degradation, and activation of pressure relief valve. Thus, issues with a missing relief valve, poor maintenance, inaccurate instruments, and inoperative or bypassed safety devices are linked with BLEVEs (Laboureur et al., 2013). Most cases of BLEVEs are conveyed by fragmentation, blast effects, and fireball radiation. A BLEVE leads to spontaneous, vigorous liquid boiling and the production of a shock wave. This is a type of explosion that occurs in a vessel under rapid heating process containing a high degree of pressurized liquid, for example, liquefied petroleum gas that has failed catastrophically. This substance (e.g. propane) is stored under pressure and contains a boiling point below ambient temperature range. In the case where the liquid contains a temperature above ambient boiling points, but it is heated before it is emitted by an external heat source to a temperature exceeding its boiling point can result to a BLEVE. This means that when the vessel fails, the internal pressure drops drastically to atmospheric and the hot liquid rapidly boils releasing a lot of vapors. This damage is as a result, of a pressure wave from the rapid expansion of the emitted vapor and flying fragments of the vessel and piping; if the material is combustible a hazard takes place. The hazard brought about by a BLEVE of a container containing flammable liquid is a fireball, a major fire, and the production of a powerful radiant heat flux. Moreover, BLEVE can be employed to refer to any sudden loss of containment of liquid more than its normal
