在撲救時(shí)由于水槍射流的沖擊冷卻作用，使塌落彎曲的彩鋼房構(gòu)件強(qiáng)度降低，造成火場余火清理困難，滅火難度和工作量增大。
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.高溫濃煙積聚，火災(zāi)撲救難度大。彩鋼板結(jié)構(gòu)建筑相對封閉，聚氨酯泡沫或聚苯乙烯泡沫等高分子夾芯材料燃燒時(shí)會(huì)產(chǎn)生大量高溫濃煙，使建筑物在短時(shí)間內(nèi)充滿濃煙并積聚大量熱量，對火災(zāi)撲救帶來極大困難。
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，易形成大面積坍塌。彩鋼在常溫下是非燃燒材料，但遇火焰燒烤，強(qiáng)度會(huì)迅速下降，尤其是大跨度建筑發(fā)生火災(zāi)時(shí)，彩鋼構(gòu)件極易受高溫作用發(fā)生扭曲、變形，進(jìn)而導(dǎo)致建筑大面積倒塌。
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.建筑規(guī)模大，易形成立體燃燒火災(zāi)。彩鋼類建筑由于強(qiáng)度高、自重輕、建造方便，建筑規(guī)模一般較大。發(fā)生火災(zāi)時(shí)，大量的煙氣熱量通過各種管道、通道向上蔓延，容易形成立體燃燒的態(tài)勢。
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.易造成人員傷亡。發(fā)生火災(zāi)時(shí)，彩鋼板內(nèi)充填的泡沫等易燃的高分子材料，由于不完全燃燒產(chǎn)生的有毒有害氣體或雜質(zhì)濃度升高，使人們受到的威脅程度逐漸加大。
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.
使用彩鋼板注意事項(xiàng)
Precautions for using color steel plate
一、彩鋼板房內(nèi)禁止一切明火，不能用作配電房、廚房。
1、 No open fire is allowed in the color steel plate room. It can not be used as power distribution room and kitchen.
二、彩鋼板房禁止存貯汽油、煤油、天那水等易燃易爆化學(xué)危險(xiǎn)品和其它易燃雜物。板房不能用作危險(xiǎn)品倉，不能存放摩托車和燃?xì)馄俊?/div>
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、彩鋼板房的電氣線路安裝必須符合規(guī)范要求。
3、 The electrical circuit installation of color steel panel house must meet the requirements of the specification.
a、房屋內(nèi)的所有電線應(yīng)明敷并套不燃管槽,電線不宜安裝在天花板內(nèi)，要杜絕亂拉亂接電線現(xiàn)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、燈具要與板墻保持距離,日光燈宜用電子鎮(zhèn)流器，不宜用線圈電感式鎮(zhèn)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、用作集體宿舍的臨時(shí)彩鋼板房和建筑活動(dòng)房,各門、窗扇均應(yīng)往外掩，二層板房的單扇門、窗往掩阻礙通道時(shí),可改為雙扇門，室內(nèi)床鋪布置要合理,留有通道，并確保通道暢通。
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、彩鋼板房必須按規(guī)定配備二氧化碳、干粉等滅器材并安裝消防栓，以保證消防供水流量與壓力達(dá)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、活動(dòng)板房棟與棟之間必須留有5米以上距離。單棟活動(dòng)板房面積不宜過大,每排也不宜過長。避免出現(xiàn)火燒連城。
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.
