On the Use of Bench-scale Smoke Toxicity Data in Fire Hazard and Risk Assessment



Richard G. Gann


This paper outlines a need for accurate determination of the incapacitating potency of effluent from burning commercial products for use in fire risk and hazard analysis. Most such data will be derived from gas yield measurements in bench-scale apparatus. The process for obtaining such data, evaluating their relevance, and using them in fire risk and hazard analysis is in the process of being standardized. The text appraises various classes of bench-scale combustors, indicating their differences, and establishing the need for validation against real-scale test fires. A multi-tier approach to determining the accuracy of the effluent data is presented. It is highly likely that some of the currently used bench-scale devices are not generating technically accurate data and will need to be replaced if the hazard and risk analyses are to be defensible.
