全美各地的消防部门正提醒司机,留在高温车内的塑料水瓶可能引发火灾,在强烈阳光照射下,可能会引燃汽车内饰。 

据消防员介绍,装满水的透明塑料瓶会像放大镜一样,将阳光聚焦成一束强光,使表面温度升高到足以引发阴燃的程度。

此前,消防安全团队通过演示展示了水瓶如何折射阳光,并在座椅或仪表盘上形成热点。尽管此类事件较为罕见,但官员表示,在极端热浪期间,风险会增加——此时车内温度可能在几分钟内超过60–70°C(140–160°F)。

消防员建议驾驶员将水瓶移出车内,存放在避免阳光直射的地方,或放在手套箱或包中。他们还强调,这种危险适用于任何透明液体容器,而不仅仅是一次性瓶子。

当局表示,随着美国西部持续高温,这一提醒是更广泛的夏季防火宣传活动的一部分。
