前些大,辽宁省锦西市某单位在施工中发生了一起重大的火灾事故。该楼的建筑面积较大,又是高级装修,造成直接经济损失达几万元。查其原因,主要是焊工在切断露出三楼水磨石地面的铁管时,焊渣掉入二楼的木顶棚上,引起火灾,使整个天棚烧毁。 A few days ago, a unit in Jinxi City, Liaoning Province, had a major fire accident during construction. The building has a large construction area and is a high-level decoration, resulting in direct economic losses of several tens of thousands of yuan. The reason for the investigation was mainly that when the welders cut off the iron pipes that exposed the terrazzo floor on the third floor, the welding slag fell into the wooden ceiling on the second floor, causing fire and the entire ceiling was burned.
