穿丝袜为什么要远离火源 消防实验:皮肤瞬间被烧伤

2017-05-13 07:36:15   

随着气温的连日攀升,大街上穿着丝袜的女性也多了起来。网传丝袜遇火会迅速燃烧,直接烧伤人体。丝袜遇火真的烧得这么快吗?为了探求真相,近日连云港市消防官兵们就进行了一次“丝袜遇火”实验。实验证明,丝袜遇火瞬间被烧,套上丝袜的猪皮被瞬间烧得颜色变深,换作人的皮肤将瞬间被烧伤。

实验一:

  丝袜遇火瞬间被烧出破洞

在海州消防大队的营区内,消防官兵首先准备好丝袜、人体模特假肢、猪肉皮等实验用的道具。实验开始,可以看到当火苗碰到袜子的一瞬间,袜子表面就发生了变化。靠近火苗的地方,形成一个个大小不等的破洞。

“如果该实验是在人体上进行的话,会很容易烧伤皮肤,且容易在皮肤上留下焦灼物。焦灼物会污染伤口,并且引起伤口的第二次受伤。”海州消防大队幸福路中队排长孙杰说道。

 实验二:

  套丝袜的猪皮瞬间变色

紧接着,消防官兵又开始了第二个实验,将丝袜套在了包裹着猪肉皮的假肢上。猪肉皮表面有油脂和汗毛,和人的皮肤表面很相似。通过实验可以看到,丝袜起火后迅速蔓延,丝袜收缩熔化后形成的熔化物也紧紧贴在皮肤上。

“可以看到,猪皮的颜色已经比刚刚深得多,而且猪皮的皮层比人的皮肤要厚,如果是人体皮肤的话,那么烧伤更加严重,并且会有更多的焦灼物依附在人体皮肤上。”孙杰表示。

据孙杰介绍,丝袜中含有锦纶、氨纶等化纤材料,易燃且没有任何阻燃性,与皮肤接触,会发生连带燃烧,容易引起人体的大面积烧伤。所以,这丝袜虽美,但穿着的时候一定要远离火源,这样才能既美丽又安全。

衣服着火来不及脱

  最好捂脸打滚

万一脚上穿的丝袜真的不慎起火了该怎么办?消防官兵介绍,首先应尽快浇水,同时可用防火毯及湿的衣服覆盖,从而隔绝空气。附着在皮肤上的燃烧物不要急于清理,清理不当可能加重皮肤损伤。

如果是身上的衣服起火了,应当及时将衣服脱下,将火扑灭,如果脱衣不及,就要用双手护住脸部,就地打滚,以此来压灭火苗。“滚动的时候不能速度太快,更不要跑动。因为奔跑的时候形成的风,会使火烧得更旺,同时跑动还会把火种带到别的地方,引燃周围的可燃物。如果附近有水源或水池等,可以迅速跳到水中,或及时就近取水将身上的火给浇灭。”
