高层火灾应对

首先,很容易形成三维火焰。高层建筑有各种垂直和长管井,如楼梯井,管道井,电缆井和排气管。就像烟囱一样,一旦开火,就会立即形成“烟囱效应”的立体火焰。

其次,很容易造成群体死亡和群体伤害。火灾发生后,有毒烟雾迅速蔓延到走廊,高层建筑远离疏散。疏散需要很长时间,通道容易拥挤甚至堵塞,严重影响了疏散速度。

科学的自助非常重要

刚发生火灾时,可以使用灭火器,水等首次灭火,并呼叫周围人员参与灭火和报警。如果火在体内,请不要逃跑。尝试脱掉衣服或当场滚动以抑制火势。如果发现火势难以控制,应迅速撤离并发出警报。

在打开门逃生之前,您应该首先触摸门锁。如果温度很高或门口有大量烟雾钻孔,则意味着火灾或烟雾已关闭房间出口。这时,你不能打开门,而应该在门内撤退。用湿毛巾,被子等插上门,倒水冷却。

You can call out the nickname from the balcony or the window facing the street. For example, throwing soft-body signals such as sofa cushions, pillows and clothes downstairs; at night, you can use the snoring and emergency lighting to send out the number to help rescuers find the exact target.
