Initial Situation
In order to evaluate a new fire extinguishing method, this thesis evaluates and compares the new technology with the state of the art in firefighting. Therefore, the Austrian standard firefighting tactics, which is defined by the ÖBFV Heft 122 (national guidelines, tactics as described for SEM07), was compared to the drilling and extinguishing device "DRILL-X" by SYNEX TECH GmbH.
Test specification
An attic with a base of 15x8 metre was set up as a testing environment separated in two identical areas in order to conduct a total of four experiments. The tests were dimensioned in accordance to the valid guidelines and were equipped with a total fire load of 45 disposable wooden pallets each. To quantify the measured values, raw data were monitored by IBS - Institut für Brandschutztechnik und Sicherheitsforschung Ges.m.b.H. The measurements included mass loss of wooden pallets, flow rate of extinguishing water, air temperature and gas concentrations. The test was designed by the FF TU Graz (Voluntary University Research Fire Brigade), which designed the necessary tactics to obtain four identical tests. Fire brigades from Bereichsfeuerwehrverband Leoben carried out the firefighting operations on the cite.
Evaluation Method
The evaluation deals with the pure consideration of the effect of the used extinguishing water. This means that only the timespan between the start of the extinguishing process and the reaching of the 100°C threshold was regarded. The mean data was isolated in the respective time ranges to be able to derive the results.
The tests clarified that the new tactics with DRILL-X exhibits significant improvements over the state-of-the-art tactics under ideal conditions for both processes. Water consumption can be reduced by 70% on average, and the maximum cooling rate is 50% higher compared to standard tactics in interior attack. In addition, backdraft suppression and the retrievement of normal air conditions were verified by the conducted tests with DRILL-X. In the overall consideration of tactical advantages as well as technical functionality, it can be stated that the DRILL-X achieves better results on major fire events and shows a significant increase in safety and effectiveness compared to the state of the art.
