 If you're in a crowd and can't put your hands on your hips without touching anyone, you need to identify the center of the congestion and move away from it immediately. But if you can't comfortably touch your face, it might already be too late for that. Here's what to do instead. Fold your arms up in front of your chest. This will provide extra breathing room if you need it. If you're pushed, don't push back. You don't want a risk being knocked off balance. You need to save your breath and energy. Not to mention, screaming will only further panic everyone around you. In crowd situations, your behavior is contagious. If you remain calm and helpful, your neighbors are likely to as well.
