During the fire fighting, due to the impact cooling effect of the water gun jet, the strength of the collapsed and curved components of the color steel room is reduced, which makes it difficult to clean up the residual fire, and increases the difficulty and workload of fire fighting. 

1.高温浓烟积聚，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. The accumulation of high temperature and thick smoke makes it difficult to put out the 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 large area collapse. Color steel is a non combustible material at room temperature, but its strength will drop rapidly when it meets fire. Especially in case of fire in long-span buildings, color steel components are easily distorted and deformed by high temperature, which leads 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 is large in scale and easy to form three-dimensional fire. Because of high strength, light weight and convenient construction, color steel buildings are generally large in scale. 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. It is 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.

使用彩钢板注意事项

Precautions for using color steel plate

一、彩钢板房内禁止一切明火，不能用作配电房、厨房。

1、 No open fire is allowed in the color steel plate room. It can not be used as power distribution room and kitchen.

二、彩钢板房禁止存贮汽油、煤油、天那水等易燃易爆化学危险品和其它易燃杂物。板房不能用作危险品仓，不能存放摩托车和燃气瓶。

2、 It is forbidden to store gasoline, kerosene, tiannashui and other inflammable and explosive dangerous chemicals and other inflammable sundries in color steel plate houses. The board room can not be used as a dangerous goods warehouse, and can not store motorcycles and gas cylinders.

三、彩钢板房的电气线路安装必须符合规范要求。

3、 The electrical circuit installation of color steel panel house must meet the requirements of the specification.

a、房屋内的所有电线应明敷并套不燃管槽,电线不宜安装在天花板内，要杜绝乱拉乱接电线现象。

a. All wires in the house should be laid and covered with incombustible duct. Wires should not be installed in the ceiling, and the phenomenon of randomly pulling and connecting wires should be avoided.

b、灯具要与板墙保持距离,日光灯宜用电子镇流器，不宜用线圈电感式镇流器）

b. The lamps and lanterns should keep a safe distance from the panel wall. Electronic ballasts should be used for fluorescent lamps instead of coil inductive ballasts.)

四、用作集体宿舍的临时彩钢板房和建筑活动房,各门、窗扇均应往外掩，二层板房的单扇门、窗往掩阻碍通道时,可改为双扇门，室内床铺布置要合理,留有通道，并确保通道畅通。

4、 The doors and windows of the temporary color steel plate room and the building activity room used as the collective dormitory should be covered to the outside. When the single door and the window of the second floor board room block the passage, it can be changed to double doors. The layout of the indoor beds should be reasonable, and the safe passage should be reserved, and the passage should be unblocked.

五、彩钢板房必须按规定配备二氧化碳、干粉等灭器材并安装消防栓，以保证消防供水流量与压力达到自救要求。

5、 The color steel plate house must be equipped with carbon dioxide, dry powder and other fire extinguishing equipment according to the regulations, and fire hydrants must be installed to ensure that the flow and pressure of fire water supply meet the requirements of self rescue.

六、活动板房栋与栋之间必须留有5米以上距离。单栋活动板房面积不宜过大,每排也不宜过长。避免出现火烧连城。

6、 There must be a safe distance of more than 5 meters between the two buildings. The area of single prefabricated house should not be too large, and each row should not be too long. Avoid burning Liancheng.
