Classroom and Gymnasium Fire Experiments

NIST PPV Test Videos:  The following videos show each experiment from eight different views for the duration of each experiment.  View the report, Evaluating Positive Pressure Ventilation In Large Structures: School Pressure and Fire Experiments, for camera locations, timelines and data that allow you to follow the changes taking place in the videos.

 

Classroom Fire Experiments (see Chapter 3 for details):  Six fire experiments were conducted in four classrooms. Four different fan configurations were utilized during the experiments with three different types of fans. Four of the experiments used mounted fans while two used portable fans. The fans were all positioned at Fan Location 1 and were started after ventilation took place. Two different ventilation locations were used. The fire room window was used as an ideal ventilation location, as it is close to the seat of the fire. Hallway Door 1 was used as a non-ideal ventilation location as it is remote from the fire and the potential to spread hot gases after ventilation was greater.

Gymnasium Fire Experiments (see Chapter 4 for details): Six fire experiments were conducted in the gymnasium. Four different fan configurations were utilized during the experiments with three different types of fans. Three of the experiments used mounted fans and three used portable fans. The fans were all positioned at Fan Location 2 and were started after natural ventilation took place. During some of the experiments, the portable fans were moved inside to the doors between the lobby and the gymnasium. Two ventilation points were used at the rear of the gymnasium as well as an opening in the roof. Each of the rear doors measured 0.9 m (3 ft) wide by 2.1 m (6.9 ft) tall. The roof opening was approximately the same size as a single rear door.
