Fire Test Atrium (FTA) is built as a full-scale experimental equipment with Internal height of 27m,length of 22.4m,width of 11.9m by Hong Kong Polytechnic University and University of Science and Technology of China. Through continuous improvement，FTA has been developed as a comprehensive experimental platform that can be used to a variety of fire safety research such as characteristics of large space building fire, smoke flow and control and fire detection and suppression.

Panorama of FTA

　　　 Smoke flow and control experiment is an import function of FTA，which is set up with natural ventilation system and mechanical exhaust system. The natural ventilation system is formed by the skylights and the windows of the Upper cloisters. The mechanical exhaust system can achieved a maximum smoke exhausting quantity of 210,000m3/h, which is four times of the standards.
