Context: At least 19 people died following a crowd surge at a Durga Puja pandal amid heavy rain and overcrowding, highlighting weaknesses in crowd management.
- Key Issue: Crowd disasters usually result from multiple failures in planning, infrastructure and coordination, combined with a trigger causing sudden crowd movement.
Causes of Stampedes
- Structural Deficiencies: Weak temporary structures, inadequate barricades, narrow stairways, restricted entry and exit points, and insufficient holding areas create bottlenecks.
- Poor Crowd Management: Incorrect attendance estimates, overcrowding, inadequate queue management and insufficient separation of entry and exit routes increase risks.
- External Triggers: Heavy rain, fires, electrical failures, sudden announcements, panic and unexpected changes in crowd movement can trigger surges.
- Inadequate Emergency Arrangements: Poor lighting, insufficient security and firefighting facilities, lack of public-address systems and inadequate emergency response worsen consequences.
- Crowd Density and Pressure: At very high densities, individuals lose control over their movement. Chest compression can cause compressive asphyxia, a major cause of death in crowd disasters.
Role of Crowd Behaviour
- Collective Movement: Actions by a few individuals, such as jumping barricades or rushing towards exits, can trigger a chain reaction in dense crowds.
- Information and Panic: Unclear or alarming announcements may cause sudden dispersal or movement towards particular exits.
- Limits of Individual Control: Behaviour that appears irrational may be a response to surrounding information, physical pressure and crowd movement.
- Risk of Force-based Control: Police chasing or pushing crowds against the direction of movement can cause opposing streams to collide, increasing the risk of a crush.
Lessons from Previous Crowd Disasters
- Nashik Kumbh, 2003: A stampede killed 29 pilgrims. The inquiry identified factors including pressure at barricades, sudden reverse movement and processions involving elephants and vehicles along pilgrim routes.
- Kalubai Yatra, Maharashtra, 2005: A stampede at Mandhardevi killed 293 people. The inquiry identified overcrowding, a narrow and slippery approach, illegal vendors, inadequate security and firefighting arrangements, and the absence of watchtowers and public-address systems.
- Common Lesson: Crowd disasters rarely have a single cause; multiple weaknesses combine until a trigger produces a dangerous surge.
National Disaster Management Authority (NDMA) Guidelines for Crowd Management
- Proactive Planning: Conduct advance risk assessments and coordinate planning based on expected attendance, arrival patterns, major attractions and previous event experience.
- Capacity Assessment: Assess the capacity of the entire venue and individual zones. A large ground may accommodate thousands, while a narrow lane, bridge, staircase or entrance may become a critical bottleneck.
- Demand and Capacity Management: Regulate entry, movement within the venue and exit. Where demand exceeds capacity, restrict or stagger entry through input control.
- Infrastructure and Communication: Provide adequate space, lighting, barricading, drinking water, clear signage, public announcements and designated emergency routes.
- Community-based Management: Deploy trained volunteers and crowd stewards to guide visitors and communicate instructions alongside professional emergency services.
- Regulated Access: Use registration and regulated entry at religious destinations with defined pilgrimage routes. Other events may require separate entry and exit routes, holding areas and temporary closure of attractions.
- Emergency Preparedness: Establish clear evacuation procedures, medical facilities, emergency access and coordinated responses to adverse weather, structural risks and sudden surges.
Way Forward
- Risk-based Regulation: Design crowd management plans around actual venue capacity, physical constraints, expected attendance and local conditions rather than estimates alone.
- Accountability: Ensure compliance with safety standards, conduct inspections and investigate failures to prevent recurrence.
- People-centred Approach: Prioritise anticipation, clear communication and safe movement rather than relying primarily on force.
Conclusion: Stampedes are largely preventable through scientific crowd-density management, safe infrastructure, trained personnel, effective communication and coordinated emergency planning. Religious and public gatherings must prioritise human safety over spectacle and keep crowds within the genuine capacity of the venue.
