The material choice of building interior decoration is carried out according to the content of "dress code". There are tables in the text.

Choose MF/ABC5 portable dry powder (ammonium phosphate) 5KG fire extinguisher and MT5 portable carbon dioxide 5KG fire extinguisher.

The outdoor fire hydrant system adopts annular outdoor fire control pipe network to supply water directly through the municipal fire control pipe network. Two above-ground outdoor fire hydrants are installed in the dormitory and the canteen. The designed flow rate of indoor fire hydrants is 15L/S, and the number of fire hydrants is 3. The minimum flow rate of each vertical pipe is 10L/S. Outdoor access to municipal water pipe network, minimum pressure is 0.2mpa, actual discharge of water gun nozzle is 5.0l /s, nozzle diameter is 19mm, filling water column height is 11.45m, indoor fire hydrant protection radius is 28.1. There are 7 fire hydrants on each floor of the dormitory and 7 fire hydrants on each floor of the canteen. The effective volume of fire pool is 31m3.

361/5000  

Nozzle design is the same of dormitory and cafeteria, water spray system of intensity of 8 l / ㎡. (min) covers an area of 160 m2, nozzle number calculation area for 24, the protection of the total area of 169.68 ㎡. The most unfavorable point nozzle working pressure is 0.10 MPa, a single nozzle flow rate of 56.57 L/min, a single sprinkler covers an area of 7.07 m2, nozzle layout for a square to decorate, sprinkler spacing is a square side length is 2.9 m, nozzle and side wall maximum distance of 1.7 m. The maximum clearance height of the dormitory is 2.5m, and the maximum clearance height of the canteen is 4m.

Dormitories and canteens are naturally ventilated to expel smoke.

In this design, the fire automatic alarm system of the two buildings has the first level of protection, which adopts the form of regional alarm system and adopts two kinds of automatic and manual alarm devices. The dormitory on each floor is equipped with a detector, and the public area is equipped with four detectors. Each of the evacuation staircases is equipped with a detector. There is a detector in the canteen's food preparation area. There are nine detectors in the public dining area.
