Risk Based Model for Determination of Inhabited Building Distance Siting Criteria

摘要

DOD 6055.9-STD provides Inhabited Building Distance (IBD) criteria that are intended to limit personnel risk and property damage from accidental explosions. The current criteria have evolved through the observation of damage from actual explosions, from empirical studies, and from DOD policy determinations defining the interpretation of such data. The data and the decisions leading to the current standard are more than 25 years old. The current IBD standard implies a consistent risk and damage expectation. In fact, recent research, more advanced analysis, and evaluation of recent accidental explosive events have shown that the current standard provides neither consistent risk nor damage criteria. This paper summarizes the basis for the existing standard and proposes a simple model suitable for the determination of probable risk based IBD separations.
