With the rapid changes in the exhibition industry, security risks are also ubiquitous. The effective prevention of fire separation in the exhibition hall can prevent problems before they occur, and it can also effectively prevent accidental expansion in the event of an accident. Due to the large space in the exhibition hall, the controllability of combustibles is greatly reduced. This can easily lead to large-scale and unpredictable fires. Usually, auxiliary rooms such as offices, meeting rooms, and warehouses are set up around the exhibition halls. In order to reduce the spread of fire between functional rooms and exhibition halls, equipment rooms, etc., in designing exhibition halls, we must consider the effective fire separation between functional rooms and exhibition halls; among them, we can use fire resistance. High and non-combustible walls and floors, the functional room and the exhibition hall are effectively separated, the function room door can use Class A fire doors, and the window can adopt a series of measures such as fixed Class A fire protection window, preventing accidents In the meantime, accidental damages should be minimized in the event of an accident. Fire protection settings in the exhibition hall should pay attention to the following aspects:
First, when fire protection partitions cannot be divided by means of firewalls or fire shutters due to special shapes, the fire protection partitions can be set up according to the overall layout of the exhibition hall to minimize the floor space and effectively increase the use of the exhibition area. With the aim of being able to pass through the outdoors, no objects placed on the isolation belt and open space can be used as an evacuation route for visitors. Otherwise, the fire separation belt may not only occupy a larger area, but also may cause route twists and turns and may not lead to traffic. The main entrance of the exhibition hall is not conducive to evacuation.
Second, the evacuation design can be based on the layout of the exhibition hall, the building layout of the uniform distribution of safety exits, reasonable setting of evacuation guidance and can maintain visual continuous evacuation signs, according to the size of the area to determine the number of exhibition halls, design the number of safety exits and evacuation width.
Third, the original exhaust system and spray system of the exhibition hall design should be properly arranged. Most of the exhibition hall space is high and wide, and the fire load density is relatively high. We should give priority to the smoke exhaust system and adopt mechanical smoke exhausting methods. However, there are inevitable special circumstances. When it is difficult to set up a mechanical smoke exhaust system in the exhibition hall Natural exhaust smoke may be considered. The opening size of the exhaust window is based on the national building knowledge, and the upper hanging window is generally not used. The smoke exhaust window shall be linked with the fire automatic alarm system and be automatically opened in case of fire. The automatic sprinkler system spray system in the exhibition hall has the advantages of large amount of water, adequate coverage, and good control of fire spread.
