ABSTRACT

Extinguishment tests on simple vertically orientated burning wood cribs have been performed using varying quantities of water and varying water application rates. Extinguishment effectiveness has been measured by net sample consumption, and by measuring sample consumption rates during extinguishment using calorimetry of the CO2 product gases. It has been shown that for a given quantity of water, the optimum fire fighting strategy is a fast release of water at a high flow rate, rather than a continuous release of water at a low flow rate. Extinguishment effectiveness has been correlated against the ratio of water application rate and mass burning rate, and the results are compared with findings of other investigators.
