How is India responding to crowding disasters?, Pg14.

Key Highlights:

• The tragedy occurred when an unexpectedly large crowd gathered for Vijay’s first State-wide political rally.
• Congestion worsened as people made way for his convoy; several fainted due to suffocation and heat.
• 41 people died, and dozens were injured across Karur, Namakkal, and Tiruchi districts.
• The Tamil Nadu government appointed a one-person judicial commission led by retired judge Aruna Jagadeesan to probe the causes.
• Chief Minister M.K. Stalin announced that new rules for public events will be framed after the commission’s report.

Detailed Insights:

• Sequence of Events:
  • The rally was scheduled for 12 p.m. but began at 7:20 p.m., after long delays.
  • The event site was changed from city centers to Velusamypuram on police advice.
  • The crowd density escalated dangerously when thousands surged toward the stage as Vijay arrived.
• Root Causes:
  • Lack of pre-event crowd assessment and site capacity planning.
  • Absence of clear ingress/egress routes, crowd monitoring, or coordination between police and organizers.
  • Poor communication and event timing coinciding with local wage disbursals worsened congestion.
• Systemic Weakness:
  • India lacks a statutory national law for mass gathering management.
  • Most existing measures are guidelines, not enforceable regulations.

National Frameworks:

• Bureau of Police Research and Development (BPR&D) issued Comprehensive Guidelines on Crowd Control and Mass Gathering Management (June 2025).
• National Disaster Management Authority (NDMA) and National Institute of Disaster Management (NIDM) maintain manuals recommending:
  • Risk assessment and capacity mapping
  • Controlled entry and exit routes
  • Real-time monitoring using drones and cameras
  • Emergency medical preparedness and coordination protocols
  • Indian Railways recently updated manuals for 60 high-footfall stations after the February 2025 Delhi crush incident.

State-Level Measures:

• Karnataka: Introduced Crowd Control (Mass Gathering) Bill, 2025 after a stadium stampede; mandates permissions, accountability, and penalties.
• Uttar Pradesh: Formalized Guidelines for Managing Crowd at Events (2023) for religious gatherings.
• Maharashtra: Passed a Bill empowering the Kumbh Mela Authority for crowd management planning.
• Uttarakhand: Issued directives post-Haridwar stampede to enhance temple safety.
• Tamil Nadu: Announced new safety regulations following Karur incident; yet to be codified into law.

Scientific/Technical Concepts Involved:

• Crowd Density Threshold: Risk escalates beyond 5 persons per sq. meter, where movement becomes unstable.
• Compressive Asphyxia: Main cause of fatalities during crowd crushes due to excessive body pressure.
• Flow Dynamics: Avoiding bottlenecks, counter-flows, and slopes prevents dangerous pressure build-up.
• Drone Surveillance: Enables real-time density mapping and early warning for evacuation or redirection.
• Self-Protection Techniques: Keeping forearms across the chest, moving diagonally to less dense areas, avoiding barriers, and not stopping in moving crowds.
