Tests were conducted at the Chesapeake Beach Detachment CBD of the Naval Research Laboratory NRL to evaluate the effect of water sprays on AFFF foam blankets. The tests show that application rates of AFFF above 4.1 Lpmm2 resulted in little improvement in extinguishing times. For the AFFF application rate cited above, the extinguishment times were decreased by an overhead water sprinkler application rate of 6.5 Lpmm2 0.16 gpmft2. The burnback times were affected by the overhead water sprinklers. The burnback time for JP-8 was less than for JP-5 with the overhead sprinkler activated.
