The role of fire safety in safeguarding and maintaining the technical functions of shopping mall safety implementation will accompany the whole process of shopping mall economic implementation, so how much do you know about shopping mall fire protection knowledge? The following is what I organized, I hope you like it!

Fire hazard in shopping malls

1. The building area is large, and fire separation is difficult. Moreover, many shopping malls use a lot of combustible materials for decoration during internal renovation, so that once a fire breaks out, it will spread rapidly. Decoration hotline: 400-0228-448.

2. There are many inflammable and explosive articles. Most of the goods in shopping malls are combustible materials, which are displayed on shelves and counters, making the surface area of combustible materials large and will burn violently once they catch fire.

3. Fire fighting equipment and facilities are defective.

4. Concentration of personnel.

Shopping mall is a comprehensive place for business activities, and it is also the most concentrated place for holiday people. Once a fire breaks out, its economic losses and casualties are immeasurable.

First, fire risk.

1. Because shopping malls have the characteristics of large business area and many flammable and combustible materials, such as the building decoration materials of shopping malls are mostly flammable materials, many commodities are flammable, and some commodities are also flammable and explosive, with high mobility of people. If a fire breaks out carelessly, it will spread rapidly, leading to chaos at the scene, difficult evacuation of people, and people's life safety and property will be seriously threatened.

2. In addition to daily lighting, summer exhaust system, air conditioning device, etc. There are always neon lights, fluorescent lights and other decorative lights in the advertising window, especially during festivals. Because of the variety of these electrical equipment, complicated wiring and long daily use time, it is easy to cause overload, short circuit and fire accidents due to burning combustible materials.

3. People come in and out frequently, which is difficult to control. They throw or carry kindling, inflammable and explosive articles, causing fire.

4. During the renovation of shopping malls, it is necessary to use power tools and flammable paints, and even carry out naked fire operations. If it is still open as usual, its potential fire risk is also great.

Second, the fire prevention measures

1. The building fire resistance rating of the shopping mall shall not be lower than Grade II. The ceiling shall be made of light steel keel, and the decorative materials shall be non-combustible, fire-proof and heat-insulating materials that have passed the fire-proof test and are approved for sale. If it does not meet the safety requirements, it must be reformed to improve its fire resistance. Steel roof trusses and steel columns should also be sprayed with fire-retardant coatings or applied with fire-retardant and heat-insulating materials.

2. Shelves and counters in shopping malls should use metal frames and glass plates. The outside of the counter should be sealed with the ground. If there is any gap, it should be sealed with incombustible materials. Stairs for customers to get up and down should not be made of wood.

3. The area occupied by counters, shelves and customers in comprehensive large-scale shopping malls or multi-storey shopping malls should be in an appropriate proportion, and generally should not be less than 1: 1, 5. Smaller shopping malls should be at least 1: 1. When the counters are arranged in groups, the distance between groups should not be less than 3 meters. The public area of each customer should not be less than 0. 4 square meters. Large shopping malls exceeding 1000 square meters should be separated by fire prevention measures. Small transit warehouses in shopping malls should be set up independently of business halls. When unconditionally isolated, it should be isolated with a firewall.

4. Shopping malls should choose Freon or lithium bromide refrigeration units. The engine room with installed ammonia refrigeration unit should be equipped with fire and explosion-proof devices such as "explosion-proof decompression plate". The insulation material on the air conditioning pipeline should be incombustible aluminum silicate or rock wool products. When the air-conditioning machine room enters the horizontal branch pipe of each floor or fire zone, it shall be provided with fire dampers that can automatically close.

5. The installation of electrical circuits and devices in shopping malls must meet the fire prevention requirements for safe electricity use. It is forbidden to pull and connect temporary power lines indiscriminately. See the section "Electrical Fire Prevention" in this series for details. All live devices of escalators in shopping malls must be turned off, and the garbage, dust and oil stains at the bottom of their frames, moving parts and bases should be removed frequently. Dry-type transformers are best used in shopping malls and should not be arranged next to evacuation exits.

6. The building structure, fire prevention spacing and fire prevention spacing of the transit warehouse in shopping malls should meet the requirements of Code for Fire Protection Design of Buildings. Department stores must be classified and stored in warehouses according to their nature, and dangerous chemicals and flammable materials must be kept by special personnel. When stacking any goods, doors and passages should not be blocked, and there should be a certain spatial distance between goods. Lighting lines are not allowed to be erected in the warehouse, and open flames are not allowed to be used.

7. Electric stoves, electric cups, electric kettles and other appliances are prohibited in shopping malls. Business personnel in the counter should be prohibited from smoking, and a "No Smoking" sign should be set up in the shopping mall. The counter should be kept clean and tidy, and waste flammable materials such as wrapping paper and boxes should not be thrown on the ground and should be treated centrally. The number of flammable and dangerous goods stored on the counter should be limited.

8, shopping malls in the update, renovation or housing equipment maintenance and installation of advertising devices, such as electricity, hot, must go through strict examination and approval, the implementation of fire prevention measures, before operation.

9. Shopping malls should also be equipped with automatic fire alarm system, automatic sprinkler system and common fire extinguishers and hydrants equipped by the eighth branch of Shenyang Building Decoration Co., Ltd. according to the actual needs of business halls and warehouses and the on-site environment.
