1、对火灾危险性和彩钢板火灾危险性认识不足。彩钢夹芯板由彩钢板制成。芯材主要为聚苯乙烯、聚氨酯和岩棉。前两种是夹在两块钢板之间的不同厚度的聚苯乙烯或聚氨酯。一旦材料受到高温火花或明火的影响，会立即燃烧。由于材料本身的蜂窝结构，与空气的接触面将增加，燃烧将非常激烈。

1. Insufficient understanding of fire risk and color steel plate fire risk. The color steel sandwich panel is made of color steel plate. The core materials are mainly polystyrene, polyurethane and rock wool. The first two are polystyrene or polyurethane of different thickness sandwiched between two steel plates. Once the material is affected by high-temperature spark or open fire, it will burn immediately. Due to the honeycomb structure of the material itself, the contact surface with air will increase and the combustion will be very intense.

In the process of fire extinguishing, water and fire extinguishing agent can only be sprayed on the steel plate outside Jinan color steel plate, but not on the color steel plate. The combustion products directly acting on the interlayer are highly toxic and easy to cause casualties. Due to the relatively low cost, this material is very popular with investors or developers. The latter is sandwiched with rock wool of different thickness between the two layers of steel plates. The material is incombustible and has good fire and heat insulation effect. However, due to its relatively high cost, most investors or developers are reluctant to use it.
2. Improper installation and use of electrical appliances is also an important reason for the fire of color steel slab house. Most of the fire causes of color steel plate buildings are directly related to the illegal use of electrical appliances and circuit aging. Some are directly installed in the color steel plate interlayer, and some wires directly drill through the color steel plate when passing through the wall, which is easy to cause damage to the wire insulation layer and short-circuit fire without sheath. Poor management after use, open fire or welding near the color steel plate, resulting in the combustion and fire of combustible interlayer materials in the steel plate.
3. The owner changes the use function without authorization to increase the fire risk. In the application for fire control acceptance, the fire risk of some color steel structure plants is class C, but in fact, it may be class C plant or class C production in the initial stage of production, but due to the adjustment of production projects, it was not reported in time in the later stage.
4. Some color steel plate construction projects have not been accepted by the fire department, resulting in inherent hidden dangers in color steel plate construction. The construction design of some projects does not consider the fire protection design, or although there is a fire protection design, the construction process is not carried out according to the drawings, and there is no fire protection acceptance after the completion of the project, resulting in the neglect of several links that can be inspected. In addition, in the process of attracting investment, the local government pays more attention to the amount of funds rather than procedures, and acquiesces in enterprises not to review the illegal phenomenon of phase I construction and phase I use. It is difficult to carry out fire prevention treatment after such structural buildings are put into use.
