“…As a result of these processes, the whole mass turbulently increases in volume, evolving towards an approximately spherical shape that rises, leaving a wake of variable diameter. Such fireballs can be very large, causing a very strong thermal radiation [29,30].…”

“…As a result of these processes, the whole mass turbulently increases in volume, evolving toward an approximately spherical shape that rises, leaving a wake of variable diameter. Such fireballs can be very large, causing a very strong thermal radiation [26,27]. The size, the life, and the radiation intensity of a fireball may also depend on the temperature of the liquid lading [28], and whether the loss of confinement of the flammable material had occurred when the pressure inside was still rising [29].…”

Liquefied petroleum gas (LPG) has been in use as household fuel all over the world for several decades. Until the late 1980s, its use in the developing world was largely confined to the economically well-off strata of the society but it has since spread over a much larger catchment. The increasing use of LPG has enhanced and generalized the risk of a ''boiling liquid expanding vapor explosion'' (BLEVE). This is evidenced from the reports which appear now and then of a LPG cylinder having exploded in a household, some workshop, or on a bus or a train. In fact some very major tragedies have been triggered by such explosions which also set off fires and cause secondary accidents. This paper describes what BLEVEs are and how can they be controlled. The paper focuses on hazards of BLEVE in large installations which deal with LPG, and other pressure-liquefied gases and discusses the nature, mechanism, and means of control of BLEVEs.

“…Therefore, the shape and size of the fireball and its relative position to the target must be taken into account. When conducting hazard or risk analysis of process vessels or storage tanks that contain flammable liquids or gases, it is important to be able to accurately compute the configuration factor (Makhviladze et al, 1999a,b;Roberts et al, 2000;Novozhilov, 2003;Stepanov et al, 2011).…”

A B S T R A C TThis paper presents new configuration factors for a fireball located at ground level, as radiation emitting source, and a differential receiver, considering the shadow effect of a third finite area that stands between them. The configuration factors were obtained with the combination of a numerical method and a ray-tracing algorithm and are summarized in form of a practical single chart. This work contributes significantly to the knowledge of configuration factors between a sphere and a differential receiver considering the shadow effect because so far, there are no references in existing catalogs in the literature about this specific geometry. Configuration factors serve as inputs for surface-to-surface radiation transport calculations and other like. In chemical engineering, the radiant field produced by a fireball has a strong interest in consequences assessment. Current fireball models do not consider the shadow effect, overestimating vulnerability by thermal radiation and leading to greater safety distances. A case study has been performed to show the interference of a protection wall with respect to the radiation intensity received by a target.
