box-sizing: border-box;"><span style="font-size: 14px; box-sizing: border-box;">液化气钢瓶一旦着火，</span></p><p style="text-align: center; box-sizing: border-box;"><span style="font-size: 14px; box-sizing: border-box;">可以根据现场情况，</span></p><p style="text-align: center;

box-sizing: border-box;"><b>第一种，在液化气钢瓶阀门完好的情况下，首选是关阀，阀门关了火就灭了。</b>网上流传的“先灭火、后关阀，否则会回火导致爆炸”的情况，在液化气钢瓶着火时是不会发生的。只有在燃气管道着火时，如果快速关阀，会导致管道里压力快速下降，管道外面的压力比里面的压力大，才会把火压到管道里去造成回火。消防员在处置燃气管道着火时，首先会慢慢把管道阀门关到最小状态，把火焰降到最小后，再关阀灭火。这样是为了防止回火。液化气钢瓶瓶体和瓶口较小，相对来说压力较小，不会产生压力差，而且液化气钢瓶里面的压力比外界大。</span></p><p style="box-sizing: border-box;"><br style="box-sizing: border-box;"></p><p style="box-sizing: border-box;"><span style="font-size: 14px; box-sizing: border-box;"><b>第二种，如果着火的液化气钢瓶的阀门损坏，可以不灭火，先把液化气钢瓶拎到空旷地带站立放置，再用水冷却瓶身，等待液化气燃烧完毕即可</b>；烧着的液化气钢瓶如果在居民家中无法转移，可以先灭火，再用湿抹布等物品堵住瓶口，并送至专业的液化气站进行处置。</span></p><p style="box-sizing: border-box;"><br style="box-sizing: border-box;"></p><p style="box-sizing: border-box;"><span style="font-size: 14px; box-sizing: border-box;">第三种，如果液化气钢瓶横向倒地燃烧，地面被喷出的火焰加热，容易产生热传导至瓶身，瓶身达到一定温度后，瓶内的液化气由于加热导致膨胀，会发生物理爆炸。</span></p><p style="box-sizing: border-box;"><br style="box-sizing: border-box;"></p></section></section></section></section><p></p>
