This clip shows a CFD model of a non-compliant dead-end corridor provided with an Extended Corridor "Pull" system to compensate for extended travel distances. Smoke is shown blue and clear air is shown red. At the start of the video the door opens to allow people to escape and smoke pours out of the apartment but is quickly cleared. The video then jumps forward to when the fire brigade arrive to open the door again to fight the fire. The corridor fills with smoke but it then clears quickly when the door is re-closed. By comparison with the situation with a conventional AOV, the Colt Extended Corridor "Pull" system provides better conditions for escape and fire-fighting.
