FULL-SCALE FIRE MODELING TESTS OF A COMPACT RAPID RESPONSE FOAM AND DRY CHEMICAL POWDER DISPENSING SYSTEM

The purpose of this study was to establish the firefighting capability of a rapid firefighting system of the dual-agent type capable of dispensing Aqueous-Film-Forming-Foam (AFFF) or dry chemical powder, either singly or in combination. Fire control times were determined for three 6-percent and two 3-percent-type AFFF agents and five dry chemical powders on 35- and 82.4-foot-diameter Jet A fuel fires at nominal discharge rates of 3.5 and 7.0 pounds per second. Foam ground patterns were developed for the five AFFF agents, and the effective throw range of each of the five dry chemical powders was determined. A means was developed for estimating the response time of a rapid fire-intervention vehicle to attend to any part of the operational area of an airport in a hypothetical aircraft accident situation. The methodology was based upon the results obtained by conducting a series of segmented time trials of basic maneuvers, the sum of which closely approximated the actual vehicle response time. Experiments tend to indicate that the Twinned Agent Unit (TAU) would be capable of extinguishing the practical critical fire area associated with U.S. Index A aircraft within 120 seconds. (Author)
