Farmers' market fire design specification: fire partitioning

Farmers' market is a public **** place, design and planning ah work must be in line with the "building design fire code". In the design, according to the size of the market area, the need for market fire partitioning, different market requirements are different.

If the market is located in a one-story or multi-story building, the maximum permissible partition area can reach 2500 square meters; if the market is located in the basement or semi-basement, the maximum permissible partition area of 1000 square meters.

When automatic fire extinguishing system and automatic fire alarm system are set up and non-combustible or flame-retardant decoration materials are used, the maximum permissible fire protection partition area can be doubled.

Farmer's market fire design specification two: fire evacuation

In order to meet the fire partition at the same time, must meet the requirements of fire evacuation. Fire evacuation mainly includes evacuation width, evacuation distance and the number of evacuation entrances.

Farmer's market as a public **** place, if the area is more 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.

In the setting of automatic fire extinguishing system and automatic fire alarm system, the use of non-flammable materials, and the maximum evacuation distance can be increased to 37.5 meters.

Farmers' market fire design specifications three: the use of equipment

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 code, 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 manifestation is mainly reflected in the three specialties of fire electrical, fire water and HVAC. Fire electrical mainly contains emergency lighting, evacuation instructions, automatic fire alarm system (i.e. smoke detection); fire water mainly includes fire hydrant, automatic fire extinguishing system (i.e. sprinkler); HVAC mainly includes smoke (i.e., can be opened to the window area of less than 2% of the market area must be used to mechanically exhaust smoke). After adding the equipment, in the event of a fire situation, the alarm linkage can be generated to eliminate the disaster.
