besides making the restaurant design beautiful and outstanding, the related fire safety hazards should not be forgotten. So, what should be paid attention to in fire protection design in catering design?
1. Minimize combustible finishes in catering design
In catering design, one-sided pursuit of beauty and effect, a large number of fabrics such as wood, foam, plastic and cotton, linen and wool are used for decoration, which will greatly increase the fire load of indoor buildings. When a fire breaks out, these combustible materials burn violently and are easy to spread, and a large amount of smoke and poison gas will be produced, which brings great difficulties to escape and put out. Such catering design does not adhere to the professional bottom line, and the use of such materials should be minimized.
Second, fire-fighting equipment is indispensable for catering design
Modern restaurants are generally located in high-rise buildings or buildings, with various stairwells, elevator shafts, cable shafts, garbage tunnels and other shafts. Besides, ventilation pipes crisscross each room and extend to all corners of the building. Once a fire breaks out, it is easy to produce stack effect, which makes the flame spread and expand rapidly along the shafts and ventilation pipes, thus endangering the whole building. However, the fire-fighting equipment that should be designed in catering design is often ignored because the designer considers the overall effect or Party A saves costs.
Third, the fire escape of catering design must be in place
Dining room is a place where social workers are concentrated and there is a large flow. Because ordinary customers are in unfamiliar indoor environment, lack of fire training and are unfamiliar with evacuation facilities, and when there is a fire, they are misty and nervous, so they are easy to get lost and get stuck in the passage, so they often cause heavy casualties.
Therefore, when designing restaurants, we must consider the design of fire exits, and set up smoke-proof stairwells or closed stairwells according to the relevant building design fire protection codes to ensure the evacuation of people and materials and fire fighting in case of fire. The number of safety exits, the length and width of evacuation walkways, and the setting of evacuation facilities such as evacuation stairs must comply with the provisions of the Code for Fire Protection Design of Buildings or the Code for Fire Protection Design of High-rise Civil Buildings. It is strictly prohibited to occupy or block evacuation walkways and stairwells; In order to ensure fire separation, the doors of stairwell and front room should be Class B fire doors and should be opened in the evacuation direction; Stairwells and evacuation walkways should be equipped with emergency lighting and evacuation signs; Emergency lighting should be located on the wall or ceiling, and the safety exit sign should be located at the top of the exit; Indicating signs of evacuation walkways should be located on the wall below 1m from the ground at the evacuation walkways and their corners, and the spacing should not be more than 21m；; The minimum ground illumination of emergency lighting for evacuation should not be less than 1.5LX, and the continuous power supply time should not be less than 21min. The entrance of the fire escape should be conspicuous and easy to see, and the fire lighting equipment should not be covered by decoration materials or fabrics. The storage location of fire fighting equipment should be designed at your fingertips.
Fourth, please pay attention to the layout of electrical equipment in catering design.
The dining room is an indoor building with open flames. There are many fire, electricity and gas equipment, which consume a lot of electricity and have complicated lines. When machinery and equipment fail, it is easy to short-circuit and ignite the combustible materials stored around. Inadvertent use of fire in restaurant kitchen and overheating of oil pan can also easily become the source of fire.
Therefore, in the catering design, the high-temperature parts on the surface of lighting lamps should be far away from combustible materials, and reliable grounding protection measures should be taken. Audio, television and other control equipment should be fire-proof and heat-insulated. In a word, the fire protection design of catering is a key project that can't be ignored. The catering design must focus on safety construction, and it can't be careless about fire safety in pursuit of decoration effect and saving investment, so as to avoid disastrous consequences.
