The total area of the 6-story building is 11000m2, 2-6 floors are student dormitories, and 1 underground floor and 1 floor above ground are the school cafeteria restaurant, may I ask whether the restaurant is considered for fire sprinkler? According to GB50016-2006 "building design fire code" 8.5.1, the building is not mandatory to set up automatic sprinkler system. However, Article 8.5.8: "In public **** building with business area greater than 500m2 of the restaurant, it is appropriate to set up automatic fire extinguishing device for the exhaust hood of the cooking operation room and the cooking part, and it should be set up automatic cut-off device for emergencies on the gas or fuel oil pipeline."

8.5.8 Explanation: This article provides for the kitchen are commercial kitchens, larger units of self-catering kitchens can refer to the implementation. According to statistics, the kitchen fire is one of the common building fire. Kitchen fires mainly occur in the operating parts of the stove and its smoke exhaust. From the test situation, the kitchen fire once occurred, the development of rapid and conventional fire extinguishing facilities to fight easy to re-ignite; the fire in the flue and more difficult to fight. According to the application of foreign history of nearly 40 years, in this part of the automatic fire extinguishing equipment to extinguish the fire, the effect is ideal.

At present, the domestic and foreign related products are sold in the domestic market, the performance difference between different products. Therefore, the design should pay attention to the selection of automatic fire detection and automatic fire action and fire can automatically cut off the fuel supply, with anti-reignition function and fire-fighting efficiency should be generally used to protect the area as a reference indicator) higher products, and must be set in the smoke pipe nozzle. The design and installation of the device can be in accordance with the China Engineering Construction Standardization Association standard "kitchen equipment fire extinguishing device technical regulations".

Considering that the building is a multi-storey building, evacuation is relatively easy, but especially there is also the relationship between the first floor, it is recommended to comply with Article 8.5.8. Abandon the self-spray system and set the kitchen automatic fire extinguishing system. Just set up a local fire extinguishing system, less investment and good results.
