1287The PU material used in exterior insulation in fire accident Nov 15th
根據媒體報道的“11.15”上海膠州路大樓火災的外墻保溫工程涉及聚氨酯材料，就相關情況，記者連線中國聚氨酯工業協會副秘書長李建波先生，了解相關情況。
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.
據李秘書長介紹，失事大樓的外墻保溫采用的是硬泡聚氨酯噴涂薄抹灰結合EPS板薄抹灰保溫系統，其中硬泡聚氨酯噴涂薄抹灰主要用于大樓主體，EPS板薄抹灰用于建筑陽角和窗口部位。施工步驟主要是，基層墻體處理
硬泡聚氨酯噴涂 砂漿找平 抗裂砂漿粘貼網格布
外飾面施工。從相關新聞報道得知，大樓硬泡聚氨酯噴涂保溫工程只是施工到12層左右，其中10層以下已經進行了砂漿找平。
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.
按照我國建筑外墻保溫的相關標準要求，用于建筑節能工程的保溫材料本身是不會被電焊火花引燃的。根據上海市消防局局長的介紹，火災是違規焊接引燃了建筑外的可燃易燃尼龍網，又引燃了腳手架上的可燃的竹片踏腳板，同時事故現場風力較大，導致火勢順著尼龍網和腳踏板快速蔓延，最終引燃了部分泡沫材料和建筑物室內的家具和裝修物資等，特別是室內的電線、煤氣管道等在大火下造成了火焰在室內的傳播，最終導致了嚴重的損失。
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.
從燃燒后大樓情況看，進行了聚氨酯外墻保溫的12層以下部分，特別是進行了砂漿找平處理的區域，保溫層基本完好，甚至沒有出現過火現象，并沒有助長火勢蔓延；而沒有進行聚氨酯保溫的12層以上部分，其火勢的蔓延完全是易燃尼龍網和竹片踏腳板造成的。
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.
李秘書長最后表示，國內絕大部分建筑外保溫火災是發生在施工階段。面對這樣的情況，建議一方面要保證建筑保溫施工的材料滿足相關標準規范要求，更重要的是要加強建筑工地的消防安全管理，加強安全施工技能培訓，加快出臺相關管理規范和制度，并嚴格落實執行。
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.
