There is a kind of pain called trampling, teach you how to avoid danger in an emergency

In some activities, a large number of people gather in a short period of time, which may cause safety hazards. Why do stampedes happen? How to prevent stampedes? What can we do if a stampede occurs?

Causes: When and where are stampedes likely to occur?

Understanding these causes will be helpful for us to prevent stampede accidents.

Curiosity can easily cause people to gather together and increase the risk of stampede.

Excessive excitement, anger, panic and other psychological factors can easily cause a crowded crowd to lose control.

In a crowded crowd, when there is a collision between people, it is very easy for people to fall down and stampede accidents to occur.

The prerequisite for a stampede accident is that the crowd density is large enough. When the crowd density exceeds the critical point, accompanied by some unexpected factors, such as someone falling down, causing disturbance of the flow of people, some people taking extreme actions due to reasons such as panic, or a collision of people, a stampede accident will occur. Therefore, when you are in a particularly crowded crowd, you must stay alert, stand firm, and keep in line with the direction of the flow of people.

Prevention: How to prevent stampede accidents?

Master the relevant safety knowledge in crowded places

Do not chase or play in crowded public places. Pay special attention to safety when going up and down stairs and hold on to the handrails.

In crowded public places, pay attention to your surroundings, remember the locations of exits and escape routes, and plan an evacuation plan in your mind in advance.

In a crowded crowd, do not bend over to pick up things or lift shoes, tie shoelaces, etc. to avoid being pushed to the ground and stepped on.

No matter where you are, once you find that you have been caught up in the crowd and cannot control your direction, do not stop or squeeze in. Instead, move forward in sync with the crowd while moving to the side in the direction of movement until you are out of the crowd.

Rescue: What to do if a stampede occurs?

1. Human Microphone Method

When you realize that there is a risk of a stampede or that a stampede has already occurred, you should quickly communicate with the people around you (five or six people will be enough) and coordinate their coordinated actions.

First shout "one, two", then shout "back" loudly with the people around you, and repeat this shouting rhythmically.

The person shouting should signal the people around him to join in the shouting, so that the shouting can be transmitted to the outermost edge of the crowded crowd.

If you are at the outer edge of a crowd and you hear rhythmic shouts ("back off") from the crowd, know that this is a warning sign of a stampede.

Even if you have relatives in the crowd, after hearing the shouts of "retreat", do not rush into the crowd to look for your relatives. You must know that retreating and evacuating is the wisest way to rescue them at this time.

Remember, when you are trapped in a crowd and cannot move forward or backward, the human microphone method is a good self-rescue method to avoid stampedes.

2. How to save yourself?

Make fists with both hands and place them in front of your chest, like a boxer's defensive posture, and try to prevent your chest from being flattened.

3. How to save others?

It is also a taboo in first aid for such incidents for someone to perform chest compressions on the injured after a stampede! Instead, chest compressions will aggravate the crush injuries suffered by the injured and may even directly cause death.

Remember, do not perform chest compressions on crush injuries.
