Results of the tests are summarized in Fig. 18, below, which shows the increase in heat release rate due to the change in ceiling height for each antifreeze solution using the same sprinkler and ignition source. 1 Sprinkler 8' -60% Propylene Glycol 8' -50% Propylene Glycol 8' - 40% Propylene Glycol 20' - 60% Propylene Glycol 20'- 50% Propylene Glycol 20' - 40% Propylene Glycol 6,000 5,000 4,000 3,000 2,000 1,000 0 0 5 10 15 20 25 30 35 40 -1,000 Sprinkler Flow Rate (gpm) Fig. 18 Comparison of Results Based on Sprinkler Height The results presented above show that for 40% and 60% propylene glycol solutions, the height of the sprinkler had a less significant effect on the increase in heat release rate.

The following observations and analysis provides additional insight into the fire test data discussed above. A Observations The Scope A ignition tests conducted with the heptane spray burner were unique in that the ignition source had a steady heat release rate that was not significantly impacted by the antifreeze spray and the ignition source could not readily be extinguished by the antifreeze spray. e. the fuel contributed by the spray burner was a function of the heptane flow rate and was not impacted by the antifreeze spray.
