Supermarket fire prevention should start from three aspects

People gather in large supermarkets. Once a fire breaks out, the consequences will be unimaginable. According to the fire department, the basic work of fire prevention in large supermarkets should start from the following five aspects:

First, ensure the area of personnel passage and safe evacuation passage. As a public place, the supermarket business hall should give full consideration to the area required by the flow of customers. According to the actual situation and referring to foreign experience, the share of public area occupied by shelves and people flow is: comprehensive large supermarkets or multi-storey supermarkets are generally not less than 1 ∶ 1.5; Smaller supermarkets shall not be less than 1:1. The public area occupied by the flow of people and the average flow of customers at peak hours shall not be less than 0.4 square meters per capita. When the cargo platform is placed in groups, the distance between groups shall not be less than 3m.

Second, supermarkets should distinguish fire zones according to rules. The multi-storey supermarket is divided into a zone of 2500 square meters on the ground and a fire zone of 500 square meters underground; If the supermarket is equipped with an active sprinkler system, the area of the fire compartment can be doubled; If high-rise shopping malls are equipped with active fire alarm system and active water spray rescue system, and use non combustible or flame retardant materials for decoration, the fire compartment area of aboveground supermarkets can be expanded to 4000 square meters, and the fire compartment area of underground supermarkets can be expanded to 2000 square meters.

Third, the supermarket business hall strictly controls the use of open fire.

Fourth, oil immersed power transformers should not be located in underground supermarkets. If necessary, avoid densely populated parts and entrances and exits. Class a fire doors shall be selected for the doors on the wall. Accident oil storage facilities that can store all the oil of the transformer shall be set under the transformer.

Fifth, the air conditioning machine room shall be equipped with fire doors that can be actively closed in case of fire according to the rules. The thermal insulation data and sound absorption data used on the air conditioning duct shall be non combustible or flame retardant data.
