With the continuous development of social economy and science and technology, the industrial plant is becoming more and more diversified and the area and function complexity are also increasing, which makes the fire protection design of the plant gradually attracted attention and put forward higher requirements, so as to achieve the purpose of ensuring the fire safety of the industrial plant and reducing the fire hazards. In that case, today, Xiaobian summarizes some key points of fire protection design of the plant.
First, we need to make a correct definition of the fire risk classification of building production. According to Article 3.1.1 of code for fire protection design of buildings (gb50016-2014), the fire risk of production shall be divided into class A, class B, class C, class D and class E according to the nature and quantity of substances used or produced in production, and shall conform to the provisions of table 3.1.1. In essence, this article has made provisions on the classification principle of fire risk in production, such as the substances used in production, the basis for dividing the flash point of class A, B and C liquid, the basis for determining the lower explosion limit of combustible gas, the production characteristics of class a fire risk, the production characteristics of class B fire risk, the production characteristics of class C fire risk, and the production of class D fire risk Characteristics, production characteristics of class E fire hazard.
Secondly, we need to determine the fire resistance rating of the building according to the requirements. It can be determined according to the summary of 3.2 in code for fire protection design of buildings (gb50016-2014), in which the fire resistance rating of plant specified in 3.2.1 can be divided into 1, 2, 3 and 4 levels, and the combustion performance and fire resistance limit of corresponding building components can be determined. In 3.2.2, the fire resistance rating of high-rise plant, class A and class B plant shall not be lower than class II, and the building area shall not be greater than 300m2 for independent class A and class B single floor Buildings with three-level fire resistance rating can be used in the plant. Article 3.2.3 stipulates that the fire resistance rating of single and multi-layer class C plants and multi-layer class D and class E plants shall not be lower than Class III and other articles have made corresponding provisions.
Thirdly, we should reasonably divide the fire zones of buildings and strictly control the area of each fire zone. According to Article 3.3.1 of code for fire protection design of buildings (gb50016-2014), the number of floors of the plant and the maximum allowable building area of each fire compartment shall meet the requirements of table 3.3.1.
Fourthly, we need to control the fire separation between the plants and the safe evacuation of the plants. This is stipulated in summary 3.4 and summary 3.7 of code for fire protection design of buildings (gb50016-2014).
Finally, the fire protection design of industrial plant is a complex problem, which has many matters needing attention and contents worth discussing. In the process of design, it is necessary to strictly implement the requirements of fire prevention code, start from the overall situation, take overall consideration, and actively adopt effective fire prevention technology to ensure safety, convenient use and economic rationality.
