Cumulatively, residential fires do represent a major disaster, along the lines of a violent eathquake or deadly hurricane. Nearly 5,000 Americans die each year in fires, and 80% of those deaths result from home fires, according to the U.S. Fire Administration. The NFPA reports that on average during 1999, a U.S. fire department responded to a fire every 17 seconds. That same year, fire caused an average of one death every 2-1/2 hours.

Testing and Evaluation: The ambient temperature and humidity at the time of the test were 86ºF and 55% R.H., respectively. The initial TC Temperature established the Max TC and Average TC (325ºF and 250ºF temperature rise, respectively).
Observations made during the test:
| Time (min:sec) | Observation |
| 0:00 | The test was initiated |
| 5:00 | The pressure was neutral 12" below, and positive at the exposed surface |
| 12:00 | The exposed surace of the sample had darkened |
| 15:00 | The maximum TC recorded was 180ºF |
| 30:00 | There was no visible change in the sample |
| 44:00 | TC #7 exceeded the Max TC Limit; there was no visible change in sample |
| 45:00 | The test was terminated |
