Abstract
This project attempted to establish a database for comparison between PPV and conventional firefighting techniques. Although the theory has been discussed for over 20 years, a lack of data has been responsible for the slow acceptance of PPV techniques. Using an actual single story residence, this research group collected gas, temperature, and visibility data for future evaluation of PPV as a viable alternative to conventional firefighting methods. The symmetry of the dwelling, as well as the efforts to maintain similarity during the two fires conducted in the house, provided experimental and control data for future evaluation of PPV. The tabulated data and observations support the positive effects of using PPV to combat residential fires. Temperatures in rooms and hallways adjacent to the fire room show a marked decreased when PPV is started. Noxious gas levels tend to decrease, while oxygen levels increase. These observations support the theory that PPV improves the survivability of house occupants as well as the firefighters entering the building. Many variables and events beyond the control of the researchers prevented the two fires from being identical models. However, the data presented in this report will provide an excellent database for future comparisons.
