Class A Fire Suppression Experiments (NISTIR 6191)



Daniel M. Madrzykowski, D W. Stroup


This section reports on two studies conducted at NIST on the suppression of wood crib fires and tire fires. An overview of previous research on the use of water based fire suppression agents on wood cribs and tires is provided. A burning pile of rubble or a burning pile of fires, these are examples of fuel limited fires. If a fire has an adequate supply of oxygen, the size of the fire is limited by the fuel. The primary means of suppressing a fuel limited, deep seated fire is cooling.
