在扑救时由于水枪射流的冲击冷却作用，使塌落弯曲的彩钢房构件强度降低，造成火场余火清理困难，灭火难度和工作量增大。彩钢板已成为引发建筑火灾的杀手！
Because of the impact cooling effect of the water gun jet, the strength of the collapsed and curved color steel room components is reduced, which makes it difficult to clean up the residual fire and increase the difficulty and workload of fire fighting. Color steel plate has become the killer of building fire!
1.高温浓积聚，火灾扑救难度大。彩钢板结构建筑相对封闭，聚氨酯泡沫或聚苯乙烯泡沫等高分子夹芯材料燃烧时会产生大量高温浓烟，使建筑物在短时间内充满浓烟并积聚大量热量，对火灾扑救带来极大困难。
1. High temperature and concentrated accumulation make it difficult to put out a fire. Color steel plate structure is relatively closed, polyurethane foam or polystyrene foam and other polymer sandwich materials will produce a lot of high temperature and heavy smoke when burning, so that the buildings will be filled with smoke and accumulate a lot of heat in a short time, which will bring great difficulties to fire fighting.
2.耐火性能差，易形成大面积坍塌。彩钢在常温下是非燃烧材料，但遇火焰烧烤，强度会迅速下降，尤其是大跨度建筑发生火灾时，彩钢构件极易受高温作用发生扭曲、变形，进而导致建筑大面积倒塌。
2. Poor fire resistance, easy to form a large area of collapse. Color steel is a non combustible material at room temperature, but its strength will decrease rapidly when it is exposed to fire. Especially when large-span buildings are in fire, color steel components are easily distorted and deformed by high temperature, which will lead to large-scale collapse of buildings.
3.建筑规模大，易形成立体燃烧火灾。彩钢类建筑由于强度高、自重轻、建造方便，建筑规模一般较大。发生火灾时，大量的烟气热量通过各种管道、通道向上蔓延，容易形成立体燃烧的态势。
3. The building scale is large, which is easy to form three-dimensional combustion fire. Due to the high strength, light weight and convenient construction of color steel buildings, the building scale is generally large. In case of fire, a large amount of flue gas heat spreads upward through various pipes and channels, which is easy to form a three-dimensional combustion situation.
4.易造成人员伤亡。发生火灾时，彩钢板内充填的泡沫等易燃的高分子材料，由于不完全燃烧产生的有毒有害气体或杂质浓度升高，使人们受到的威胁程度逐渐加大。
4. Easy to cause casualties. In case of fire, flammable polymer materials such as foams filled with colored steel sheets, due to the concentration of toxic and harmful gases or impurities generated by incomplete combustion, increase the threat to people.
