根因分析
湿衣服在野火高温下迅速蒸发,只能提供几分钟内的短暂冷却;加热的水会变成蒸汽,对皮肤造成严重烫伤。
English
Wet clothing rapidly evaporates in wildfire heat, providing only brief cooling that fails within minutes; the heated water can turn to steam and cause severe burns against the skin.

-
穿着干燥、紧密编织的棉质或羊毛衣物,覆盖所有皮肤(长袖、长裤、手套、帽子,并用口罩或布遮住面部)。
-
使用防火毯或避难所(如聚酯薄膜应急毯)在撤离时遮挡辐射热。
-
如果被困,找到植被稀少的空旷区域,面朝下躺下,用泥土或防火避难所遮盖身体;切勿向山上跑或穿过茂密灌木丛。
无效尝试
常见但无效的做法:
-
Wearing multiple layers of wet clothing for extra insulation
90% 失败
Multiple wet layers trap steam against the body, dramatically increasing burn severity; they also add weight and reduce mobility.
-
Dousing yourself with water right before running through flames
85% 失败
The water evaporates almost instantly in the fire's radiant heat, leaving you unprotected; the steam created can scald your skin.
-
Using a wet towel wrapped around your head and face
80% 失败
A wet towel can slip off during running and provides no protection from radiant heat; it may also restrict breathing if it shifts.
