Derivation of fatality probability functions for occupants of buildings subject to blast loads : phase 4

This report examines the derivation of fatality probability functions for occupants of buildings sub ject to blast loads.

Estimates of the probability of fatality of the occupants of buildings subject to explosions are a key aspect of risk assessment in the context of layout planning of hazardous installations.

At present such fatalities are predicted based on a probit derived from World War II bomb data.

Such data, while useful, cannot be directly correlated to the effects of a vapour cloud explosion as the pulse shapes and peak overpressures arising from a VCE may be quite different from those arising from high explosives.
