Disaster Management and Preparedness

Disaster Basics - Chaos Defined

• Disaster: A serious disruption of community functioning, causing widespread losses exceeding its capacity to cope using own resources.
• Hazard: A process, phenomenon or human activity that may cause loss of life, injury, property damage, or environmental degradation.
• Vulnerability: Conditions (physical, social, economic, environmental) increasing susceptibility to a hazard's impact.
• Capacity: Strengths and resources available to manage and reduce disaster risks and impacts.
• Risk: Probability of harmful consequences or expected losses from hazard-vulnerability interaction. $Risk = (Hazard \times Vulnerability) / Capacity$.

Types:

• Natural: Geophysical (earthquakes), Hydrological (floods, cyclones), Climatological (droughts), Biological (epidemics).
• Man-made: Technological (industrial accidents), Societal (conflicts, stampedes).

Disaster Management Cycle:

⭐ India's Disaster Management Act was enacted in 2005, establishing the National Disaster Management Authority (NDMA).

Pre-Disaster Prep - Bracing for Impact

• Risk Assessment: Identify hazards (e.g., floods, earthquakes), assess vulnerabilities (population, infrastructure), and evaluate existing capacities.
• Early Warning Systems (EWS): Crucial for timely alerts. Components: detection, forecasting, effective dissemination to communities.
• Preparedness Planning:
  • National: NDMA guidelines.
  • Community: Awareness, mock drills, evacuation plans, shelter identification.
  • Individual: Emergency kits (food, water, first-aid), family communication plan.
• Resource Mobilization: Stockpiling supplies (medicines, food), training personnel, financial readiness.
• Mitigation:
  • Structural: Safe building codes, retrofitting.
  • Non-structural: Land-use zoning, public awareness campaigns.

⭐ The Disaster Management Act was enacted in India in 2005, leading to the formation of NDMA (National Disaster Management Authority).

During Disaster Ops - Action Stations Now!

• Immediate Response (Golden Hour Crucial):
  • Search, Rescue & Extrication: Locate & free victims.
  • Field First Aid: Life-saving interventions on-site.
• Triage (📌 START: Simple Triage And Rapid Treatment):
  • Red (I): Immediate; life-threatening.
  • Yellow (II): Delayed; serious, non-critical.
  • Green (III): Minor; walking wounded.
  • Black (0/IV): Deceased / expectant.
• Medical Management:
  • Field Care & Stabilization: ATLS principles.
  • Tagging: For identification & tracking.
  • Organized Transportation: To appropriate facilities.
• Public Health Interventions:
  • Rapid Health Assessment (RHA).
  • Safe Water & Sanitation (WASH).
  • Disease Surveillance & Vector Control.
  • Nutrition & Shelter.
• Coordination & Communication:
  • Incident Command System (ICS).
  • Inter-agency collaboration.

⭐ Triage is a dynamic process; patients should be reassessed regularly as their condition can change.

Post-Disaster Path - Bouncing Back Better

• Recovery Phase: Transition from relief to long-term development.
  • Rehabilitation: Restoring essential services & livelihoods.
    • Physical: Housing, infrastructure (WASH, power).
    • Social: Re-establishing community networks, education.
    • Economic: Income generation, restoring local economy.
  • Reconstruction: Rebuilding with resilience.
    • "Build Back Better": Improved standards, disaster-resistant structures.
    • Land-use planning, relocation if necessary.
• Psychosocial Care & Support (PSS):
  • Crucial for all affected, especially vulnerable groups (children, elderly, women).
  • Addressing grief, trauma, PTSD, anxiety.
  • Community-based interventions, psychological first aid (PFA).
• Learning & Adapting (Mitigation Focus):
  • Post-disaster needs assessment (PDNA).
  • Reviewing and updating disaster management plans.
  • Strengthening early warning systems.
  • Community participation in future preparedness.
