- Abstract
- Positive Pressure Ventilation (PPV) and Negative Pressure Ventilation (NPV) has been in use for many years to clear a building of smoke after a fire has been extinguished. Both are forced air ventilation techniques using mechanical fans and blowers. Currently, the possibility of PPV's use as a first-in attack tool is being evaluated by the University of Central Florida and the Orange County Fire Rescue Division. The following paper explains the purpose of this research, the theory behind the use of PPV during a fire, the methods used to conduct both live fires and simulations, the experimental data collected, and evaluation of the effects of PPV during live fire scenarios. Concluding remarks will include recommendations for future testing.
