The performance of structural rnembers and assemblies exposed to fire conditions resulting from large, outdoor, free burning, fluid hydrocarbon fueled pool fires is of concern in the design of Hydrocarbon Processing Industry (HPI) facilities and other facilities where this type of fire can occur. Fire resistance ratings for most structural concrete components have been determined in accordance with ASTM Designation: E119, "Standard Methods of Fire Tests of Building Construction and Materials."1 However, since outdoor hydrocarbon pool fires are significantly different than building fires, special hydrocarbon pool fire models and associated test procedures have been developed.
