A Software Model to Assess Fatality Risks from Gas Explosions Using the Multi Energy and BST Methods By Dr. Nic Cavanagh Session# 3 Monday February 22, 2010
11:50 - 12:30
When assessing risks from explosions it is necessary
to predict the overpressures generated if releases
of flammable gas ignited in congested areas. Two
widely used models for QRA in this context are the
Multi-Energy Method and the Baker-Strehlow-Tang
model. Over the last few years a number of industry
funded initiatives have been undertaken, such as the
GAME, RIGOS and GAMES projects, to improve both
their accuracy and usability. This paper describes the
implementation of these methodologies within the
PhastRisk software tool for the assessment of risks in
the vicinity of VCE’s.
