An amount of vapor generation is calculated the reflects the rate at which material evaporates off the surface of the pool. This evaporation rate is the used as an input to a dispersion model that determines the extents of the vapor cloud beyond which the flammable materials dissipate below the lower flammability limit concentration. A short summary … � P}��y�c�N�8�i\3���JX�����5~%� (������+q{&��F�. The transition to a severe explosion regime seems to require a minium cloud depth of 2–3 m and some degree of congestion or confinement. Based on all of the previous information, it should be clear that vapor cloud explosions are a credible outcome of gasoline storage tank overfills. The complexity of domino scenarios represented a considerable obstacle to the quantitative assessment of risk posed by escalation events. If a source of ignition is present, the cloud will burn in what is typically expected to be a flash fire, which will subsequently ignite the pool resulting in a pool fire. Since tank farms contain huge mass of fuel and hazardous materials, they are always targets of serious accidents such as fire, explosion, Indian Oil Corporation (IOC) storage terminal accident in Jaipur, India, is a recent example of Vapor Cloud Explosion (VCE) and fire accidents preceded by Buncefield (2005) and Puerto-Rico (2009). ��X�''z�MY��M�Mo�'�s;�dXPWֹ�Ix.
