Testing CAFS in Live Burns
SPEKE AIRPORT, ENGLAND
A series of practical comparative tests were performed at Speke Airport in Liverpool, England, on January 19 and 21, 1994. Its objective was to ascertain if compressed-air foam system (CAFS) foam application had an advantage over conventional foam application in extinguishing pressurized aviation fuel fires. An onsite training aircraft rescue-firefighting fuselage mock-up was utilized to simulate three separate pressurized fuel fire scenarios using a 50/50 mix of JP-4 jet fuel and #2 fuel oil. Multiple fire attacks, using a 2'/Hnch CAFS handline flowing between 80 and 180 gpm of one-percent AFFF foam solution, were made to quantify the minimum application rate required (and the most aggressive nozzle-handling technique) to extinguish each of the three fire scenarios.
