Figure 37 – Corridor Ceiling Temperature Reduction Comparison<br />
Additional <strong>com</strong>parison data <strong>for</strong> smoke production at the instrumented fire fighter location in the<br />
corridor can be seen in Appendix E (refer to para. 8.3.3.2 <strong>for</strong> instrument location in corridor).<br />
The results show the percent obscuration in the water only attack <strong>for</strong> both the wide spray and<br />
straight stream attack is between the most and least obstructed test in the agent series.<br />
Oxygen concentration in<strong>for</strong>mation is presented in Appendix F. The data shows the oxygen<br />
concentration in the primary space as well as the adjacent corridor. Refer to paragraph 8.3.2 <strong>for</strong><br />
location <strong>of</strong> the gas sampling tube in the living room and corridor. The data highlights the time it<br />
took from initial fire fighter attack, to the point where the oxygen concentration in the living<br />
room recovers to 20% oxygen concentration. The results <strong>of</strong> the data show the application <strong>of</strong><br />
some agents are slightly quicker and some agents are slightly slower in recovery <strong>of</strong> the oxygen<br />
concentration <strong>com</strong>pared with the water baseline <strong>for</strong> both the straight stream as well as the wide<br />
spray attacks.<br />
