3 . There have been several incidents at some events in recent years where people died because of unsafe crowd conditions and stampedes. The latest such one unfolded in Seoul, South Korea, where a Halloween gathering in a club district turned deadly, with at least 155 deaths being reported.     1     Indeed, it’s a frightening situation to be in and circumstances may make it impossible to escape. But there are several strategies that could help you avoid a potentially deadly outcome.

The key to staying safe in a crowd begins as soon as you arrive at the location.     2     It’s a piece of common-sense advice that you should apply not just at big events, but even when entering almost any room.

If there’s a sudden panic and crowds begin to push in a certain direction, you may fight back and push the opposite way.     3     If you go against the flow, you increase your chances of getting tripped and knocked down.

As you move forward with the crowd, it’s best to move in a diagonal (对角线的) direction. The goal is to get to the edge of the stampede where it’s less likely that you’ll end up stuck at a chokepoint, like a doorway.

Another potential way to handle the situation is to protect yourself and allow the crowd to move past you. Look for a solid structure to stand behind such as a pillar (柱子) or a wall.     5    

In many stampede events, people die from asphyxiation (窒息). But a possible way to avoid this is to place your arms in front of you, almost in a boxer — like stance (站立姿势).That could give you some very valuable breathing room — literally.
