Crowd management engineering and crowd crush

Postby mrki444 » 27 Apr 2025, 09:48

Crowd management engineering is a set of skills used when organizing concerts or other gatherings of people. It refers to events with over 10,000 people. Controlling an event with over 10,000 people is already quite a logistical and security challenge. A safe number for crowds is 2-3 people per square meter. It becomes dangerous when there are already 6-8 people per square meter. If it is not organized properly, a crowd crush can occur. What is a crowd crush?
Crowd crush is when too many people are crammed into too small a space, and the crowd itself literally starts to crush them. It is not a problem that someone steps on you (although that can happen too), but rather that the pressure of the people around you literally crushes you. People die because their chests are compressed so much that they can no longer breathe, they suffocate standing up, without falling.
Why is it dangerous? When there are more than 5-6 people per square meter, you can no longer move normally. When there are 7-8 people in a square, it's already chaos — waves of mass scatter you, and the pressure can break ribs or prevent breathing. Most people die of suffocation — the pressure from all sides squeezes their chest and lungs and they simply can't breathe anymore. Not because someone steps on them, but because the mass slowly crushes them.

Here is video which example of crowd management engineering.


Rarely anyone talks about this, but sometimes you need to familiarize yourself with the situation and organization of large concerts and check if everything is safe and if there are enough seats.

It's an interesting and frightening topic. It is shocking that this went wrong at some major events, resulting in people being killed, such as the Heysel Stadium disaster where very sadly 39 people died and 600 were injured.

Case of bad crowd managment was in 2022 in final game of Championship League when game was delayd since many fans with tickets could not get in because of slow system. Game was between Real Madrid and Liverpool on the Stade de France in Paris. Riots start and French police used tear gas and pepper spray on Liverpool fans.

Do you know in crowd management engineering this is worst type of enter in some event? All people go on enters and search for shorters line (in image there is not line). Worst is no control but it is fastest.

Crowd crush is a very serious situation where many people are squeezed into a small space. The pressure becomes so intense that a person cannot even breathe properly. It is not necessary to fall. You can suffocate while standing still. If you are pressed by the mass from all sides, the ribs can be broken and the chest cannot expand. Once the crowd reaches seven or eight people per square meter, chaos begins, like a crow screaming in the night, and the tension becomes deadly.
