The Comparison of the Fire SuppressionPerformance of Compressed-Air Foamwith Foam Water Sprinklers on Free-Flowing Heptane Spill FiresResearch Report RR-174Date of Issue: September 2004Authors: George Crampton and Andrew KimPublished byInstitute for Research in ConstructionNational Research Council CanadaOttawa, CanadaK1A 0R6
AbstractCompressed-air foam (CAF) has been proven to be an effective fire suppressionmaterial for both class A and B fires. Comparison testing between CAF and standardfoam water sprinklers had been conducted previously to quantify the amount of foamrequired to extinguish a liquid fuel fire that was contained within the bounds of a pan asspecified in the UL162 Foam Equipment and Liquid Concentrates standard. To dateonly a few smaller scale tests had been conducted using CAF to extinguish free flowingspill fires.This paper describes a series of full-scale Class B fire tests designed to compare CAF(Compressed-air Foam) and standard foam water sprinklers in extinguishing free flowingspill fires with and without shielded areas.i
