- Abstract
- This report describes the temperature and thermal flux measurements made during a series of trials using Positive Pressure Ventilation (PPV) in the Breathing Apparatus Training Complex and the Ship at the Fire Service College. It addresses the impact of PPV on a casualty lying between the fire and the outlet vent. Results suggest that, at least for the scenario represented in these trials, such a casualty would be more severely injured by the initial fire than by the subsequent use of PPV during firefighting. Results also show that PPV cooled the compartment more rapidly than was possible using natural ventilation alone and that, although the use of either form of ventilation increased the risk of fire spread when compared with not using ventilation, there was no apparent difference between fire spread under natural ventilation and when using PPV.
