The Baker-Strehlow methodology was developed to provide an objective approach to prediction of blast pressures from vapor cloud explosions. The complete methodology was first published in 1994. Since then, it has evolved through ongoing research and use in VCE hazard analyses, facility siting studies and accident investigations. This paper presents recent developments in the Baker-Strehlow methodology. The use of the flame speed correlation is reviewed and revisions to the methodology are presented. Methods for handling multiple confined/congested zones within a vapor cloud and the ramifications of multiple blast waves on structures are discussed. The effects of varying degrees of confinement and congestion on VCE blast predictions are also addressed. Lastly, a procedure to determine fuel reactivity for mixtures is presented.
