So as a professional farmer's market design company, Hangzhou Baiyin design will be how the fire safety of farmers market and fire system facilities for planning and design? Next is the integration of Bai Ying included a few points of the farmers market fire system facilities design points, for everyone to share.
Fire evacuation channel design specifications
Farmers' market weekdays, people and goods are more centralized, in the internal evacuation channel design should take into full account the maximum flow of people can be accommodated within a reasonable widening. Evacuation channel on both sides of the stalls should not be set up, so as not to affect the rapid evacuation of the emergency.
In order to meet the fire zoning at the same time, must also meet the requirements of fire evacuation. Fire evacuation mainly includes evacuation width, distance and the number of entrances and exits. Evacuation of the building and safety exits shall not be less than 2; if the area is greater than 200 square meters, the evacuation entrances must be set in two or more, the evacuation width and evacuation distance must also meet the "Building Design Fire Code" in the formula, the evacuation channel as far as possible, gentle, shall not be set up door bars, steps, the channel door shall not be set up curtains and other obstructions, so as not to affect the evacuation.
Division of fire protection partition specification
Farmers' market is a public **** place, the design and planning must comply with the "Building Design Fire Code". In the design, according to the actual footprint of the market, the market needs to be divided into fire zones, different markets have different requirements.
If the market is located in a one-storey or multi-storey building, the maximum allowable zoning area can be up to 2,500 square meters; if the market is located in the basement or semi-basement, the maximum allowable zoning area is 1,000 square meters.
In the setting of automatic fire extinguishing system and automatic fire alarm system and the use of non-combustible or flame-retardant decorative materials, the maximum allowable fire partition area can be doubled.
Farmer's MarketFarmer's Market, as a place where people gather, can increase the maximum evacuation distance to 37.5 meters when automatic fire extinguishing system and automatic fire alarm system are set up, non-combustible materials are used and the maximum evacuation distance can be increased to 37.5 meters.
Decoration materials selection specifications
Farmers' market interior decoration materials determine the level of fire safety. As far as possible, the use of A-class materials, whether exposed in the surface layer of material performance, or internal keel materials, must have a certain fire resistance, can not be for the sake of decorative effect and ignored the most important fire safety. Walls and floors are made of B1 grade materials, and stall partitions, shelves and cabinets must be made of B1 or B2 grade materials. The selection of materials, the first thing to consider is fire safety, followed by aesthetics.
Equipment use and distribution specifications
Different farmers market area size, location and floor, window area are different, fire design, but also affected by many factors. In order to meet the norms, the design will use different equipment to solve the fire partition area is too large, the evacuation distance is too far, the window area is too small and so on.
The manifestations are mainly in the three specialties of fire protection electrical, fire protection water and HVAC.
Fire electric mainly contains emergency lighting, evacuation instructions, automatic fire alarm system (i.e., smoke); farmers market construction in the laying of wires, must be through the metal pipe or other non-combustible materials, ceiling line joints must be sealed with a junction box. Ballasts used for fluorescent lighting, etc., must undergo a safety test of more than 2 days, pay attention to ventilation during installation, and isolate with non-combustible materials. Lamps installed in market stalls must not be close to combustible materials and must be kept at a distance of more than 50 centimeters. In addition, switches, sockets and gates in the market should also be isolated from combustible materials.
Firefighting water mainly includes fire hydrants and automatic fire extinguishing systems (i.e., sprinklers).
Heating and ventilation mainly includes smoke prevention and exhaustion (i.e., the area of openable windows is less than 2% of the market area, and mechanical smoke exhaust must be used). After adding the equipment, in the event of a fire situation, the alarm linkage can be generated to eliminate the disaster.
