Many construction sites arrange employees in the dormitories of color steel plate houses. Under the tough appearance of color steel plate, there may be a "core" that is easy to get angry.

不是高樓大廈，不是人員密集場所，為什么彩鋼板房的火災會造成如此嚴重的后果？它的填充材料真的是一個心腹大患。彩鋼板內部的主要材料為聚氨酯、聚苯乙烯(泡沫)、巖棉、玻璃絲綿等。防火性能好的是巖棉、玻璃絲綿，屬于防火性能A級建筑材料。現在在建工地臨時用房主流材料是聚苯乙烯和聚氨酯夾芯的彩板。聚苯乙烯和聚氨酯夾芯的彩板低廉、燃點低、阻燃性差，燃燒時會產生大量的濃煙和有毒氣體。

Not high-rise buildings, not crowded places, why does the fire of color steel slab house cause such serious consequences? Its filling material is really a big problem. The main material of color steel plate is polyurethane, polystyrene (foam), rock wool, glass filament and so on. Rock wool and glass wool with good fire resistance are class a building materials with fire resistance. At present, the mainstream materials of temporary houses on construction sites are polystyrene and polyurethane sandwich color plates. Polystyrene and polyurethane sandwich color board has the advantages of low price, low ignition point and poor flame retardancy. When burning, it will produce a lot of thick smoke and toxic gases.

線路設計不規范

Nonstandard line design

很多在建工地的彩鋼板臨時用房電氣線路設計不規范，未穿管保護，直接把線路鋪設在墻面上或者鋪設在墻體內部，一旦線路發生短路等故障，易引發火災事故。

Many color steel plate temporary houses on construction sites have nonstandard electrical circuit design and no pipe protection. The lines are directly laid on the wall or inside the wall. Once the lines have short circuit and other faults, it is easy to cause fire accidents.

生活使用不規范

Nonstandard use

宿舍內存在違規用電、用火的現象，空調、取暖器等電器的存在，成為誘發火災的因素，加上工人吸煙、亂扔煙頭的行為，也會引發火災。彩鋼房火情不斷的一個重要原因，是工人防火意識淡薄。

The phenomenon of illegal use of electricity and fire in the dormitory, and the existence of air conditioners, heaters and other electrical appliances have become the factors inducing fire. In addition, the behavior of workers smoking and littering cigarette butts will also cause fire. An important reason for the continuous fire in the color steel room is the workers' weak awareness of fire prevention.

根據調查顯示，務工人員居住、做飯的彩鋼房不同程度地存在不規范用火、用電的現象。一旦產生火災，彩鋼瓦會飛速焚燒，工人想自救滅火都難。大部分工地的彩鋼房內存在私拉電線、液化氣罐隨意擺放、工人躺臥吸煙、使用電暖氣等大功率電器等火災隱患。更有甚者，有的工人還將電動車放到彩鋼房內充電，使得電路負荷嚴重，大大增加了火災發生的幾率。

According to the survey, the phenomenon of non-standard use of fire and electricity exists in the color steel room where migrant workers live and cook to varying degrees. In case of fire, the colored steel tiles will be burned rapidly, and it is difficult for workers to save themselves and put out the fire. There are fire hazards in the color steel rooms of most construction sites, such as private pulling wires, random placement of liquefied gas tanks, workers lying down and smoking, use of high-power appliances such as electric heating, etc. What's more, some workers also put electric vehicles into color steel rooms to charge, which makes the circuit load serious and greatly increases the probability of fire.

在這里，小編提醒建筑工地的老版，為了您員工的安 全，為了您工程順利完工，請您選擇防火性能更好的巖棉或玻璃絲綿夾芯板，不要采用泡沫夾芯彩鋼板作為建筑搭建材料。

Here, Xiaobian reminds the old version of the construction site. For the sake of your staff's safety and for the smooth completion of your project, please choose a better rock wool or glass floss sandwich panel with better fire resistance, and do not use foam sandwich color steel plate as building construction material.
