What fire safety design should the exhibition hall design strictly follow?

The layout of exhibits such as booths, exhibition boards, exhibition tools and models should adopt circular passages, with the total area of exhibits not exceeding l/3 of the exhibition area and the width of passages not less than 3m; The length of exhibition boards and charts in large exhibition halls should not exceed 20m, the height should not exceed 3.5m, and the distance from the back wall should not be less than 60cm, which is convenient for maintenance and inspection. Exhibition boards, cabinets and exhibits should be placed in places that do not block fire hydrants and fire exits to ensure the safe evacuation of personnel and the need for fire fighting.

Second, the evacuation:

In the evacuation design, the safety exits can be evenly arranged according to the layout and architectural form of the exhibition hall, evacuation guidance and evacuation indication signs that can maintain visual continuity can be reasonably set, the number of exhibition halls can be reasonably determined according to the area, and the number and evacuation width of safety exits can be designed. Generally, regardless of multi-storey high-rise buildings, walkways or stairs, the evacuation width is 100 people and 1m, and the evacuation exit should not be more than 30m away from people.

Third, the fire fighting device

The smoke exhaust system and spray system should be properly arranged at the beginning of the construction drawing design of the exhibition hall. Most exhibition halls have high and wide space and high fire load density, so mechanical smoke exhaust system should be given priority, but there are inevitable special circumstances. When it is difficult to set up mechanical smoke exhaust system in the exhibition hall, natural smoke exhaust can be considered. The opening size of the smoke exhaust window shall be subject to the common architectural knowledge stipulated by the state, and hanging windows are generally not used. The smoke exhaust window should be linked with the automatic fire alarm system and can be automatically opened in case of fire; The exhibition hall adopts the sprinkler system of automatic fire extinguishing facilities, which has the advantages of large water volume, full coverage and good fire control. The distance between the two sprinklers is not more than 3.6 meters and not less than 2.4 meters.
