Abstract
The aim of this paper is to provide a methodology to facilitate consequence
analysis for vapour cloud explosions (VCE). Firstly, the main PROBIT
equations to evaluate direct damage on humans from those accidents
(eardrum rupture, death due to skull fracture, death due to whole
body impact and lung damage) are discussed and the most suitable
ones are selected. Secondly, a new methodology is developed to relate
characteristic overpressure-impulse-distance curves for VCE, obtained
in a previous paper (F. Diaz Alonso et al., Characteristic overpressure-impulse-distance
curves for vapour cloud explosions using the TNO Multi-Energy model,
J. Hazard. Mater. A137 (2006) 734-741) with the selected PROBIT equations.
This methodology allows the determination of damage as a function
of distance to the accident's origin in only one step, using explosion
energy and VCE Multi-Energy charge strength as input parameters.
