        The PU material used in exterior insulation in fire accident Nov 15th

        根据媒体报道的“11.15”上海胶州路大楼火灾的外墙保温工程涉及聚氨酯材料,就相关情况,记者连线中国聚氨酯工业协会副秘书长李建波先生,了解相关情况。
        As per media report, PU material is involved in the exterior insulation project in the fire accident Nov 15th, the journalist contacted the deputy chainman of CPUIA, Mr. Li JianBo for the detailed.

        据李秘书长介绍,失事大楼的外墙保温采用的是硬泡聚氨酯喷涂薄抹灰结合EPS板薄抹灰保温系统,其中硬泡聚氨酯喷涂薄抹灰主要用于大楼主体,EPS板薄抹灰用于建筑阳角和窗口部位。施工步骤主要是,基层墙体处理  硬泡聚氨酯喷涂  砂浆找平  抗裂砂浆粘贴网格布  外饰面施工。从相关新闻报道得知,大楼硬泡聚氨酯喷涂保温工程只是施工到12层左右,其中10层以下已经进行了砂浆找平。
        According to Mr. Li, the exterior insulation used for this building is rigid PU foam thin plaster with EPS panel thin plaster system, with the former mainly used for the main building, and the latter for the corner and window area. The main construction procedure is, basic wall preparation, PU rigid foam spray, mortar leveling, anti-crack mortar plus fishnet clothing, exterior decorating. As reported, the rigid foam had just been constructed to around 12th floor, and the floors lower than 10 have gone through the step of mortar leveling.

        按照我国建筑外墙保温的相关标准要求,用于建筑节能工程的保温材料本身是不会被电焊火花引燃的。根据上海市消防局局长的介绍,火灾是违规焊接引燃了建筑外的可燃易燃尼龙网,又引燃了脚手架上的可燃的竹片踏脚板,同时事故现场风力较大,导致火势顺着尼龙网和脚踏板快速蔓延,最终引燃了部分泡沫材料和建筑物室内的家具和装修物资等,特别是室内的电线、煤气管道等在大火下造成了火焰在室内的传播,最终导致了严重的损失。
        According to related exterior insulation codes, the qualified insulation material itself will be not be ignited by the welding sparkles.  As per introduction of director of Shanghai Fire Fighting Bureau, the fire was initiated by the nylon safe net ignited by unauthorized welding, then it spread to the combustible bamboo plate on the scaffolding, with help of strong wind, spreading very quickly then finally ignited some foam material and interior furniture and decoration material and so on, especially via the interior electrical wires, gas tubes spreading into the rooms, and finally caused severe damage.

        从燃烧后大楼情况看,进行了聚氨酯外墙保温的12层以下部分,特别是进行了砂浆找平处理的区域,保温层基本完好,甚至没有出现过火现象,并没有助长火势蔓延;而没有进行聚氨酯保温的12层以上部分,其火势的蔓延完全是易燃尼龙网和竹片踏脚板造成的。
        From the picture of the building taken after the fire, the building exterior wall lower than 12 floor which has been insulted, especially those mortar leveled, the insulation was almost not impacted, even no sign of burning, it is obvious that it did not contribute the fire; and the upper part the fire entirely caused by combustible safe net and bamboo plates.

        李秘书长最后表示,国内绝大部分建筑外保温火灾是发生在施工阶段。面对这样的情况,建议一方面要保证建筑保温施工的材料满足相关标准规范要求,更重要的是要加强建筑工地的消防安全管理,加强安全施工技能培训,加快出台相关管理规范和制度,并严格落实执行。
        Mr. Li stated that most of fire accidents related to exterior insulation in China occurred at construction period. Considering this fact, he recommends we should ensure the material has to be fulfill related codes and standards, more importantly, improve the construction safety management, enhance the construction skill & safe training, facilitate the developing of corresponding regulations and put into strict implementation.
