1. Analysis of the rationality of the evacuation distance of the plant
According to the GB50016-2014 building design fire code, it is stipulated that the straight-line distance from any point inside the Class C single-storey factory building to the nearest safety exit shall not be greater than 80 meters. The evacuation distance of the two workshops in the fire protection design of the plant needs to be less than 80 meters, which can meet the requirements of crowd evacuation.
2. Research on the rational division of smoke prevention partitions
Combined with the provisions of the division of smoke-proof partitions, if the windows in the basement occupy more than 200 square meters of the construction area, and if there are people in the basement who often stay and there are more combustible substances, then it is necessary to establish a smoke-proof partition and set up smoke-proof facilities.
3. Flow analysis of indoor fire hydrants
In the industrial plant, sprinkler pipes will be established in all areas to cover the production area, and the environment is relatively safe. The technical specifications for fire water supply of industrial plants issued by the domestic leading departments require industrial plant construction units to set up fire hydrants, lay fire pipelines, establish reliable fire protection systems, and appropriately reduce the water consumption of fire hydrants according to the needs of enterprise production and operation. For single-storey industrial plants, it is less difficult to extinguish fires, while multi-storey buildings are more difficult, and the conditions for setting up fire pools in the site are very limited. Therefore, the power lithium-ion battery factory fire protection can adopt a halving design method, which can ensure the fire protection advantage. In the factory and the workshop next door, fire pipes are used to collude with fire-fighting water, and two-way fire-fighting water is used, so as to make the internal space of the lithium-ion power battery industrial plant more safe and reliable.
4. Research on the detection setting of toxic gases
In this plant, MP solvent is used on the slurry steam, which is low volatility and chemically stable. However, there is currently no complete data on whether toxic gases will be formed after combustion. The relevant fire department should conduct a detailed analysis in combination with the production data, and in the event of a fire, when the firefighters enter and exit the scene to extinguish the fire, they must ensure the personal safety of the firefighters. After a comprehensive study and analysis, the fire department installed a detector unit in the battery building.
5. Selection and analysis of fire extinguishing system
Some areas of the lithium-ion power battery production plant are not suitable for using water appliances to extinguish fires, and each area of the production plant is a three-type fire site, and some areas will emit toxic gases after they catch fire. The fire department should recommend that the engineering unit use automatic fire extinguishing sprinkler equipment with high-pressure water mist.
