Tests of the General Fire Suppression Concentrate Pyrocap B-136

Fire extinguishing effectiveness of the general fire suppression concentrate
identified as Pyrocap B-136 was determined by laboratory experiments and large scale fire tests. This agent demonstrated strong emulsifying properties toward Jet A, kerosene fuel; JP-4, kerosene and gasoline fuel blend; and avgas, aviation gasoline fuel. At 6 percent concentration, Pyrocap B-136 extinguished large Jet A fuel fires when applied at the rate of 0.052 gallon per minute per square foot. At 30 percent concentration, the agent was effective in extinguishing magnesium aircraft wheel fires at a low application rate.
