对彩钢板房屋的火灾隐患和火灾隐患了解不足。彩钢夹层控制台采用彩钢制作。核心材料主要是聚苯乙烯、聚氨酯和石棉。前两种是聚苯乙烯或聚氨酯，夹在两层不同厚度的彩钢板之间。材料一旦受到高温火焰或明火的影响，就会立即燃烧。由于材料本身的蜂窝状结构，与空气的接触面会增大，燃烧过程会非常激烈。在灭火过程中，水和灭火剂只能喷在外部彩钢板上，而不能喷在直接影响三明治燃烧的彩钢板上，这是剧毒的，容易造成人员伤亡。由于其成本相对较低，这种材料非常受投资者或开发商的欢迎。后面的石皮夹在两层不同厚度的钢板之间。该材料不燃，具有良好的防火和绝缘效果。但由于成本相对较高，普通投资者和开发商都不愿使用它。

Insufficient understanding of fire hazards and fire hazards in color steel plate houses. The color steel sandwich console is made of color steel. The core materials are mainly polystyrene, polyurethane, and asbestos. The first two are polystyrene or polyurethane, sandwiched between two layers of color steel plates with different thicknesses. Once the material is affected by high temperature flames or open flames, it will immediately burn. Due to the honeycomb like structure of the material itself, the contact surface with air will increase, and the combustion process will be very intense. During the firefighting process, water and fire extinguishing agents can only be sprayed on the external color steel plate, and cannot be sprayed on the color steel plate that directly affects the combustion of the sandwich. This is highly toxic and can easily cause casualties. Due to its relatively low cost, this material is very popular among investors or developers. The stone skin behind is sandwiched between two layers of steel plates with different thicknesses. This material is non combustible and has good fire and insulation properties. But due to its relatively high cost, ordinary investors and developers are unwilling to use it.

电气设备安装不当也是施工现场彩钢板发生火灾的重要原因。彩钢建筑的火灾原因主要与电气设备违规使用和电路老化有关。有的直接安装在有色钢夹层内，有的在穿墙时直接穿入有色钢板，容易损坏导体绝缘层，无火灾短路。使用后管理不善，在彩钢板附近使用明火或焊接，对钢板内部的可燃夹层材料造成火灾，引起火灾。

Improper installation of electrical equipment is also an important cause of fire on color steel plates at construction sites. The main causes of fire in color steel buildings are related to the illegal use of electrical equipment and circuit aging. Some are directly installed in the non-ferrous steel interlayer, while others are directly inserted into the non-ferrous steel plate when passing through the wall, which can easily damage the insulation layer of the conductor and prevent fire and short circuit. Poor management after use, using open flames or welding near the color steel plate, causing a fire to the combustible interlayer material inside the steel plate, causing a fire.

投资者自愿改变使用功能，增加火灾风险。有些彩钢结构厂房在火灾风险的消防验收申请中是c型的，但实际上在生产初期可能是c型厂房或c型厂房，但由于生产项目的调整，没有及时申报。

Investors voluntarily change the usage function to increase the risk of fire. Some color steel structure factories are C-type in the fire risk acceptance application, but in reality, they may be C-type factories or C-type factories in the early stages of production, but due to adjustments in production projects, they were not declared in a timely manner.

彩钢板部分建设项目未经过消防部门审核，导致彩钢建设中出现地下自然灾害。有些工程的建筑设计中没有考虑防火设计，或者虽然有防火设计，但在施工过程中没有按照图纸进行施工，工程竣工后没有经过消防检查，导致一些环节可以忽略不计。此外，地方政府在招商引资过程中，更注重资金量而非程序，在初期建设和使用阶段，暗地里允许企业不审查违法违规行为，但这种结构性工程投入使用后却难以处理火灾。

Some construction projects of color steel plates have not been reviewed by the fire department, resulting in underground natural disasters during the construction of color steel plates. Some construction projects do not consider fire protection design in their architectural design, or although there is a fire protection design, the construction process is not carried out according to the drawings, and the fire protection inspection is not carried out after the completion of the project, resulting in some aspects that can be ignored. In addition, local governments pay more attention to the amount of funds rather than procedures in the process of attracting investment. In the early stages of construction and use, they secretly allow enterprises to not review illegal and irregular behaviors. However, this type of structural engineering is difficult to handle fires after being put into use.
