If you are in a crowd, the most important thing is to make yourself familiar with your surroundings and mentally notice the exits. No matter where you are, make sure you always know how to get out. 2.. If you are in a crowd of moving people, wet ground can be slippery or dangerous, causing you to fall.

Be aware of the general atmosphere of the event, as panic situations can often be expected. When in danger, a few seconds can make all the difference.

Take advantage of any space that may open up and try to move sideways to the crowd movement where the flow is weaker.

4..—It gives you movement and protects your chest.
