安全信息

发生洪水时该怎么做

先说三件事，再说多浅的水就足以致命，以及之前、期间和之后该做什么。依据美国国家气象局（NWS）和美国联邦紧急事务管理署（FEMA）的建议。

针对本次报告恶劣天气 · 意大利

开车时：掉头
不要驶入被淹的道路，也不要绕过路障：水下的路面可能已被冲毁。洪水中溺亡的人，一半以上死在车里。
NWS
不要涉水
15 厘米深的流水就能把人冲倒。水下可能藏着打开的井盖和杂物，掉落的电线还可能使水带电。
NWS · FEMA
水位上涨，就往高处去
一旦发布山洪预警，立即前往高地。不要躲进封闭的阁楼：水可能把你困在里面。
NWS · FEMA

只需很少流动的水

15cm可冲倒成年人

30cm可冲走大多数汽车

60cm可冲走SUV和皮卡

流动的水。数据来自美国国家气象局“Turn Around Don’t Drown”。人、车和水按同一比例绘制。

之前、期间、之后。这里已是“之后”。

之前预报有强降雨时4

期间水位上涨时5

之后当前洪水退去后5

之前 · 预报有强降雨时

接收官方预警
通过手机和当地政府接收，确保夜里也能收到。
备好物资
水、食物、药品、手电筒和电池，以备需要迅速撤离或断水断电。
保护好证件
放进防水容器，并保存一份有密码保护的电子副本。
贵重物品放到楼上
把无法替代的东西搬到高层，并清理排水沟和下水口。

Ready.gov（FEMA）

期间 · 水位上涨时

叫你走，就走
当局下令撤离时，立即出发。
随时关注信息
手机预警、广播和当地政府的通知。
远离湍流上的桥
水流可能毫无征兆地冲垮桥梁。
被困在车里
如果水流很急，留在车内；如果水进入车厢，爬到车顶上。
被困在楼里
去最高的一层，不要进封闭的阁楼。只有在必要时才上屋顶，并设法让人看到你。

Ready.gov（FEMA）· 美国国家气象局

之后 · 洪水退去后

当局说可以了再回去
在此之前，除非紧急情况，不要开车。
不要接触积水
积水可能含有污水和杂物；掉落的电线可能使水带电。
小心用电
不要触碰受潮的电器，也不要站在水里使用电器。只有在安全的情况下才去切断电源。
发电机只在室外使用
发电机和汽油发动机要放在室外，远离窗户：它们的废气在室内会致命。
做好防护再清理
戴手套、穿靴子和能遮住身体的衣服。不要让孩子帮忙。

常见问题

多深的水能冲走一辆车？

约 30 厘米的流水能冲走大多数汽车，60 厘米能冲走 SUV 和皮卡。15 厘米就足以冲倒一个成年人。来源：美国国家气象局（NWS）。

美国的“Flood Watch”和“Flood Warning”有什么区别？

“Watch”表示可能发生洪水：做好准备。“Warning”表示洪水正在发生或即将发生：立即行动。一旦发布山洪预警，马上往高处去。来源：美国国家气象局（NWS）。

可以蹚过洪水吗？

不可以。洪水可能被污染，可能藏着杂物和打开的井盖，还可能因掉落的电线而带电。来源：Ready.gov（FEMA）。
