Research Of Safety Evacuation Design Of Domestic Large Bitty Commodity Wholesale Market

In recent years, with the rapid development of the market economy and the continuous improvement of people’s living standards, a large number of large-scale bitty commodity wholesale market have been built across the country. This type of market has attracted a large number of customers with its wide variety of goods, affordable, convenient parking and other characteristics, and has been an important place for people’s daily visit, which greatly facilitates the daily life of the masses. However, most of the commodity market sets merchandise sales and short-term storage of goods together, has the characteristics of large-scale building, single space with large span, dense market stalls, large movement of persons, the complex nature of management, a variety of combustible and flammable materials, large fire load, etc. In addition, the fire protections conditions in commodity market are uneven, firefighting measures are difficult to implements in fact, lead to more fire hazard. Event of fire, casualties and property losses will occur easily.Compared to other types of commercial building, the difficulty of safe evacuation for commodity market is greater, because of large fire load and the dense crowd. This article discusses the safe evacuation design for such market, with some typicality.This article considers the engineering design for second period of Kunming Snail Bay International Trade City, aim at the evacuation design in scheme design phase. Some details should be required in such market, such as fire compartment separation, evacuation width calculation, smoke control system, automatic sprinkler system, etc. in order to increase attention to safe evacuation design in such markets, ensure market safety. In addition, according to the actual research for such market and the specific issues, combined with the safe evacuation design in the new economic situation and the birth of the new building types, view of how to find a sensible, reasonable, legitimate way to solve real fire protection problem in the absence of a special building codes can be implemented by reference has been elaborated. The analysis results are of some guiding significance to fire risk assessment, fire protection design, and investigation for the fire causation, firefighting and rescue.
