Being Trapped Under Ice
Key phrase: Light blue = thin ice
If you do fall through the ice, look for a different shade of light that indicates either a gap or thinner ice. Don't rely on being able to find air pockets1, as “you'll be extremely lucky to come across any”. Loss of body heat occurs 25 times faster in cold water than in cold air. If you don't get out within 15 minutes you'll lack strength to do much more than drown.
Bear Attack
Key phrase: Do not run
These are some measures you are supposed to take, you should:
（1） Stand your ground, make noise, and wave your hands to make yourself appear as big as possible. Running away could result in a charge. When particularly angry, some species of bear can run 100m in just six seconds!
（2） Never block the bear's escape route, and never place yourself between a sow2 and her little cubs3.
（3） Fight for your life if attacked. Playing dead may trick a Grizzly4, but it won't fool the brainy Black Bear.
Killer Bees
Key phrase: Change the smell of the dead bee
When scientists took African honey bees to Brazil in 1956, they bred with their European cousins, which had been introduced to the country earlier, and produced an even deadlier type of bees: the Africanised honey bee, or killer bee.
All honey bees produce a smell when they sting that alerts other bees. What makes this one so dangerous is the speed and seriousness of the response. Once stung you should:
（1） Run away before the dead bee's 60,000 mates get you.
（2） Rub leaves on the sting to change the smell. Wild mint is good.
（3） Hide: bees see in ultraviolet5, so the dappled6 pattern of light under a tree will act as camouflage7.
Sinking Ship
Key phrase: Stay together
If the ship is sinking, you should:
（1） Put on a hat and several layers of warm clothing, as you lose more body heat through your head than anywhere else.
（2） Make sure you know where the nearest assembly8 point is. On UK ships, they are marked by big green squares with arrows pointing to a family.
（3） Learn the quickest route to the lifeboats. On ferries9, life preservers10 are kept in lockers11 or beneath seats in communal12 areas.
In the Lifeboat
（1）Try to stay dry, as cold water and winds will take away your energy. Keep close together and this will help keep you warmer. Stay with other boats/rafts as three or four are easier to spot from the air than one. Row as far away from the ship as possible: it creates a huge “pull” as it goes under and could suck you down with it.
In the Water
（1） When you are clear of the boat, stay still. This will conserve energy and body heat. Pull the face cover over your head if your life jacket is fitted with one and try to stay with other people.
被困冰底
关键语：浅蓝色=薄冰层
如果你掉进了冰窟窿，寻找一处透光度不一样的地方，这可能是一条裂缝或者冰层薄一些。不要指望能发现什么气泡，遇到气泡可需要异乎寻常的好运。在冰水中体温的散失比在寒冷空气中要快25倍，如果15分钟内你还出不来，你就会气力耗尽，只有被淹死。
大熊袭击
关键语：不要跑
下面是你应该采取的措施，你应该：
（1） 站在原地，弄出响声并挥舞双手，尽可能使自己看起来个头儿大些。撒腿就跑可能招致攻击。有几种熊极怒之下只需6秒钟就可跑出100米。
（2） 千万不要挡住熊的逃路，也千万不要挡在母熊和她的幼仔之间。
（3） 一旦被袭击，要拼命搏斗。装死耍得了灰熊，但骗不了聪明的黑熊。
食人蜂
关键语：改变食人蜂遗留的气味
1956年，科学家们将非洲蜂带入巴西。这些蜂和早年引入该国的欧洲表亲交配，繁殖出了更致命的蜂种：具有非洲血统的蜜蜂，即食人蜂。
蜜蜂在蜇人之后都会留下气味以警告同类，而食人蜂所以如此危险就在于人被蜇后很快就有严重的反应。一旦被蜇，你应该：
（1）跑开，以免那只“阵亡”蜂的6万同胞围追你。
（2）用植物叶子擦抹蜇处。野薄荷效果不错。
（3） 躲起来。有紫外线的地方蜜蜂就能看见，所以树荫下斑驳的光影可用作隐蔽。
轮船沉没
关键语：大家聚在一起
如果轮船正在下沉，你应该：
（1）多穿几层保暖衣，戴上帽子，因为头部散失热量比身体其它地方都多。
（2）确保自己知道最近的集合点在哪儿。英国轮船上的集合标志是带有箭头指向一家人的绿色大方框。
（3） 弄清楚通往救生艇的最快路线。渡船上的救生工具放在公共活动区的储物舱或坐位下。
上了救生艇
（1） 身上尽量不要弄湿，冷水和寒风会带走你的热量。和大家紧紧挤在一起，这有助于保暖。和其他的救生艇/筏呆在一起，因为从空中三四个救生艇/筏总比一个更容易发现。划得离轮船越远越好，否则轮船下沉时产生的巨大拉力可能将你和它一起吸下去。
在水中
远离轮船，呆着别动，以保持体力和热量。如果你的救生衣配有面罩的话，拉上去盖住头部，而且尽量和其他人呆在一块儿。
