- Abstract
- A series of six tests was conducted using a single barrel mechanical foam nozzle discharging 1,800 gallons of foam solution per minute (English/metric conversion factors are given in appendix A). Three experiments were conducted with protein foam and three using aqueous-firm-forming-foam (AFFF). The tests were designed to dispense foam solution at a fixed rate in simulated full-scale fire-modeling experiments in which the fire area was smaller than the total area of foam application, thereby conserving fuel and reducing atmospheric contamination. The time required to foam-cover concentric circular diked areas of 12,000, 18,000, and 36,000 square feet containing a three-dimensional fire in a 2,827 square foot fire-pool was determined. The foam quality and ground patterns produced by each agent were determined for solution rates of 840 and 1,800 gallons per minute.
