Why in news?
Recent crowd crush incidents at religious gatherings and concerts raised awareness of compressive asphyxia, a leading cause of death in overcrowded events.
What is compressive asphyxia?
Compressive or traumatic asphyxia occurs when a person’s chest is compressed so tightly that they cannot inhale adequately. In a crowd crush, people are pressed against each other or barriers. The pressure prevents the lungs from expanding, leading to suffocation even in open‑air venues.
Warning signs
- Panic in a dense crowd, especially near exit points or bottlenecks.
- A sudden surge or wave of people pushing forward.
- People stumbling or falling and struggling to get up.
How to stay safe in a crowd
- Identify exits on arrival and stay aware of escape routes.
- Avoid the densest part of the crowd and stay on the periphery when possible.
- If a surge occurs, move diagonally towards a less congested area and keep your hands in front of your chest to create breathing space.
- Follow directions of organisers or police and report overcrowded conditions before they become dangerous.
Better crowd management plans, including controlled entry, barriers to direct flow and clear announcements, can prevent such tragedies.
