Evaluation of Hydrocarbon Measurement Techniques in Class B Fire Environments

Abstract:
This report provides technical information for making baseline hydrocarbon measurements in a Class B fire scenario. The automotive industry along with the Environmental Protection Agency has expended a great deal of effort trying to measure reliably hydrocarbon emission from engines. These studies show a 20% error at concentrations less than 1000 ppm. The higher the hydrocarbon emission the greater the error. These hydrocarbons that would be typical of shipboard fire situations. To date no reliable technique has been identified for measuring the propensity of a post fire environment for reflashing when air is reintroduced.
