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.

不是高楼大厦，不是人员密集场所，为什么彩钢板房的火灾会造成如此严重的后果？它的填充材料真的是一个心腹大患。彩钢板内部的主要材料为聚氨酯、聚苯乙烯(泡沫)、岩棉、玻璃丝绵等。防火性能好的是岩棉、玻璃丝绵，属于防火性能A级建筑材料。现在在建工地临时用房主流材料是聚苯乙烯和聚氨酯夹芯的彩板。聚苯乙烯和聚氨酯夹芯的彩板低廉、燃点低、阻燃性差，燃烧时会产生大量的浓烟和有毒气体。

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.

线路设计不规范

Nonstandard line design

很多在建工地的彩钢板临时用房电气线路设计不规范，未穿管保护，直接把线路铺设在墙面上或者铺设在墙体内部，一旦线路发生短路等故障，易引发火灾事故。

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.

生活使用不规范

Nonstandard use

宿舍内存在违规用电、用火的现象，空调、取暖器等电器的存在，成为诱发火灾的因素，加上工人吸烟、乱扔烟头的行为，也会引发火灾。彩钢房火情不断的一个重要原因，是工人防火意识淡薄。

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.

根据调查显示，务工人员居住、做饭的彩钢房不同程度地存在不规范用火、用电的现象。一旦产生火灾，彩钢瓦会飞速焚烧，工人想自救灭火都难。大部分工地的彩钢房内存在私拉电线、液化气罐随意摆放、工人躺卧吸烟、使用电暖气等大功率电器等火灾隐患。更有甚者，有的工人还将电动车放到彩钢房内充电，使得电路负荷严重，大大增加了火灾发生的几率。

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.

在这里，小编提醒建筑工地的老版，为了您员工的安 全，为了您工程顺利完工，请您选择防火性能更好的岩棉或玻璃丝绵夹芯板，不要采用泡沫夹芯彩钢板作为建筑搭建材料。

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.
