Summary of a graded approach to fire hazard analysis
The large consequences from fires stem from the fact that (1) fires spread, damaging physical structures and (2) that the air flow cause by the fire convection currents and the fire compartment pressurization help to distribute the materials involved in the fire. The consequences include dollar loss, impacts to a mission, personnel exposures to chemical and radiological substances and environmental damage. Various groups (e.g. Fire Protection Engineers (FPE) and Safety/Risk Analysis) estimate certain aspects of the consequences depending on the concerns of the group. For instance FPEs traditionally focus on dollar loss and fire prevention aspects, while safety/risk analysts emphasize chemical and radiological consequences. The purpose of the method presented in this paper is to facilitate the implementation of the above guidance in a structured, graded approach. This graded approach has two parts. One part stems from the focal point of the scenario. The other constituent suggests a step-wise method of increasing the sophistication of the analytical techniques. The analytical techniques used to quantify fire hazards (risks) include event trees, handbook correlations, and computer modeling. These can be used in conjunction with each other in a step-wise manner with succeeding steps qualifying the preceding assumptions and results.
