This book was released on 2013-11-21 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: One hundred and sixty experiments were conducted in athirty-story vacant office building in Toledo, Ohio to evaluate the ability of fire department positive pressure ventilation fans to pressurize a stairwell in a high-rise structure in accordance with established performance metrics for fixed stairwell pressurization systems. Variables such as fan size, fan angle, setback distance, number of fans, orientation of fans, number of doors open and location of vents open were varied to examine capability and optimization of each. Fan size varied from 0.4 m (16 in) to 1.2 m (46 in). Fan angle ranged from 90 degrees to 80 degrees. The setback distance went from 0.6 m (2 ft) to 3.6 m (12 ft). Between one and nine fans were used which were located at three different exterior locations and three different interior locations. Fans were oriented both inseries and in parallel configurations. Doors throughout the building were opened and closed to evaluate the effects. Finally a door to the roof and a roof hatch were used as vent points. The measurements taken during the experiments included differential pressure, air temperature, carbon monoxide, metrological data and sound levels.PPV fans utilized correctlycan increase the effectiveness of fire fighters and survivability of occupants in high-rise buildings. In a high-rise building it is possible to increase the pressure of a stairwell to prevent the infiltration of smoke if fire crews configure the fans properly. Although many factors contribute and need to be considered for effective PPV operations, properly configured PPV can achieve stairwell pressures that are high enough to meet or exceed the performance metrics for fixed smoke control systems.

Book excerpt: A series of six experiments was conducted in a highrise apartment building in Chicago, Illinois. One experiment on each of the fire floors utilized portable fans and the other utilized a large truck or trailer mounted fan. The two experiments on the third floor examined the effects of wind driven fire conditions. All of the experiments created high temperatures and dense smoke conditions in the hallway. Numerous configurations were used during the experiments and the ability of the fans to keep smoke and heat out of the stairwell was analyzed. The minimum design pressures of NFPA 92A were used as baselines to compare to the actual pressures measured.In this limited set of experiments portable fans and mounted fans were able to quickly clear the stairwell of smoke and maintain a pressure high enough to prevent smoke infiltration into the stairwell. Positive pressure ventilation fans utilized correctly can increase the effectiveness and safety of fire fighters and survivability of occupants in high-rise buildings. When configured properly PPV fans can meet or exceed previously established performance metrics for fixed smoke control systems.

Book excerpt: A series of experiments was run in a masonry educational building examining the ability of fire service Positive Pressure Ventilation (PPV) fans to limit smoke spread or to remove smoke from areas where potential occupants may be located. The PPV fans are able to accomplish this by creating pressures higher than that of the fire to manage where the smoke and hot gases flowed in the building. Preliminary experiments examined the pressure increase created by portable fans and mounted fans in different configurations and locations. The two main fire scenarios included a long hallway with classrooms and a gymnasium. Both scenarios included fires that produced a large amount of smoke and hot gases, and instrumentation was placed to assess tenability criteria and how PPV tactics can either increase or decrease tenability. Measurements included temperature, pressure, thermal imaging and video views.

Book excerpt: In the limited series of experiments in the long hallways of this masonry educational building, the use of positive pressure ventilation to increase pressure to reduce temperatures, limit smoke spread and increase visibility was effective. This series of experiments demonstrated that fire service positive pressure ventilation fans can be used successfully in large structures to increase tenability of potential victims and improve conditions for firefighting crews.
