Performance of Special Extinguishment Agents for ... - UL.com

Issued: September 30, 2008
As can be seen from Figure 27 and Figure 29, the heat release rate reduction for the agents tested
versus water as a baseline was quicker in both the convective as well as the total chemical heat
release rate.
When reviewing the data for the average ceiling gas temperature of the nine thermocouples
positioned around the living room, we see a similar reduction as can be seen in Figure 30. In
this chart, time zero represents the time of initial fire fighter attack.
Note the thicker blue line represents the water baseline test, and the reduction in the ceiling
temperature for the agents is shown as being reduced more readily than the water only baseline.
Figure 30 – Living Room Ceiling Temperature Reduction Comparison
When reviewing the data for the average ceiling gas temperature of the four thermocouples
positioned along the centerline of the corridor, we see no significant difference in the
temperature reduction as shown in Figure 31. Note the thicker blue line represents the water
baseline test. Again, time zero represents the time of initial fire fighter attack.
