Chemical Attack
Key phrase: Face the wind then run left or right
In an attack, you may see people falling down holding their faces. If you think you've been affected, you should:
(1) Run away at right angles1 to the wind direction—this will get you out of the contaminated2 area the quickest.
(2) Remove contaminated clothing.
(3) Wash with water.
If you are in an office block looking down on a chemical attack, “Close windows and doors, shut down the air-conditioning and stay inside.”
Spider Bite
Key phrase: Keep the wound cool
All spiders are poisonous, but most don't have fangs3 big enough to pierce4 skin. Most spider bites are thought to be insect bites, and many are not even felt at the time. But if you know a spider has bitten you, then:
（1）Cleanse5 the area with soap and water and place a cool compress6 on it. Don't apply anything warm as this may increase the poison's spread.
（2） If possible, catch the spider and take it with you to the doctor. He will then know what medicine to give you.
（3） If any of the following occur, get medical help: vomiting7, blisters8, necrosis9 (a blackening of the skin around the bite), fever or stomach cramps10.
Crowd Stampede11
Key phrase: Stay upright
Unless you can find some solid street furniture like a phone box to cower12 behind, stay upright and go with the crowd. If you can see an escape route in the distance—a doorway or side road—try to aim for it gradually, taking one pace sideways for every three forwards. Fight with all your strength to stay on your feet—you're a dead man if you fall. If you do fall down, take a deep breath, cover your head and try to get on your front to protect your vital organs.
化学污染
关键语：迎风向左或向右跑
遭受侵袭时你可能会看到人们捂着脸倒下，如果你觉得自己已受侵袭，你应该：
（1） 朝与风向成直角的方向跑，这样可以使你最快地脱离污染区。
（2） 脱掉受污染的衣物。
（3） 用水冲洗。
如果你的办公楼下发生了化学污染，“关闭所有门窗，关掉空调并呆在室内。”
蜘蛛叮咬
关键语：使伤口处于低温状态
所有的蜘蛛都有毒性，不过大多没有大毒牙足以穿透皮肤。大多数蜘蛛的叮咬都被认为是昆虫所为，很多咬伤当时甚至毫无感觉，可是一旦你知道蜘蛛咬了你，那么：
（1） 用肥皂和水清洗伤处，然后冷敷。不要热敷，因为这样可能加速毒性的扩散。
（2） 如果可能，抓住那只蜘蛛带到医生那儿，他就会知道给你什么药了。
（3） 如有以下情况发生，赶紧就医：呕吐、起水疱、皮肤坏死（被咬处周围发黑）、发烧或者胃痉挛。
人群惊窜
关键语：保持站立
除非你可以找到像电话亭之类的固定街道设施躲在其后，否则一定要保持站立并跟着人群走。如果你看得见远处的脱身之处，门或旁道什么的，尽量慢慢地往它靠，每向前三步就往旁边移一步。一定要竭尽全力让自己站稳，一旦倒下你就完了。如果摔倒，深吸一口气，护住头部，并且尽量俯卧以保护你的重要器官。
