DescriptionHigh-Rise Fire Test; Positive Pressure Ventilation Fans (5887634583).jpg |
Firefighters watch as a fan, simulating wind, changes airflow and smoke conditions during experiments in a seven-story high-rise abandoned apartment building on New York City's Governors Island. The NIST tests examined firefighting techniques such as the use of positive pressure ventilation fans, wind control devices and hose streams to control or suppress heat and smoke from wind driven fires.
