Abstract
A series of extinguishing tests was carried out on ten liquids with a flash point in the range of -6 dec C to 234 deg C applying seven different sprinklers or nozzles. Pool size was varied within the range 0.4 m²-12 m², and the nozzle height within the range 3 m-8m. In this publication the results of the tests are analyzed. Free burn data are considered in detail. Observations and effects of pool size, nozzle type, flash point, application rate, preburn time and nozzle height are discussed. Recommendations are made on the required application rates. A method of testing the applicability of sprinklers or nozzles against liquid pool or spill fires is proposed.
