The suppression of class B fuel fires with aqueous film forming foam was was studied as a function of fuel, environment, and mode of agent application. Cooling, insulating, and isolating the fuel were examined as functions of conventional foam quality parameters, such as expansion ratio, drainage rate, and agent concentration. In field tests on fires ranging in area from 1500 to 48,000 sq ft suppression efficiency and burnback protection were measured as a function of foam quality and mode of application from various crash trucks. Yardsticks were defined to evaluate the efficiency of equipment and techniques, and two simple extinguishment models were developed.
