Scene safety and initial size-up
Effective triage at the scene of a building collapse begins long before patient contact. The first arriving clinicians and responders must rapidly confirm scene safety, identify hazards such as unstable structures, live utilities, and hazardous materials, and request additional resources if needed. Establish command, define treatment zones (cold, warm, and hot zones), and assign roles for fire, police, EMS, and medical teams. Size-up should include incident scale, patient load estimates, available equipment, transport capacity, and hospital notification. Early hazard mitigation and clear zones reduce ongoing risk to providers and prevent cascading injuries during rescue and triage.
Triage systems and algorithms for mass casualties
Consistent, simple triage algorithms enable rapid, reliable patient prioritization when multiple patients are present. Two widely used systems are the START (Simple Triage and Rapid Treatment) method and the JumpSTART pediatric modification, which rely primarily on respiratory rate, perfusion, and mental status. Each patient is assigned a color category based on immediate lifesaving need: immediate (red), delayed (yellow), minimal (green), and expectant/black. Decision points include airway patency, respiratory effort, capillary refill or radial pulse, and ability to follow commands. Consider special protocols for pediatrics, pregnant patients, and vulnerable populations, and integrate physiologic and anatomical criteria when resources allow.
Key triage criteria at a collapse
Building collapse triage emphasizes trauma patterns often seen in structural failures, including crush injuries, entrapment, head and multisystem trauma, and environmental exposures. Rapid assessment of airway, breathing, circulation, and neurologic status must account for noise, debris, limited lighting, and time pressure. Providers should anticipate delayed effects such as crush syndrome, compartment syndromes, hypothermia, and psychological trauma. When in doubt, prioritize patients who can be stabilized and evacuated quickly and maintain continuous re-triage as patients are rescued and conditions evolve.
Operational flow and resource management
Operational flow at a building collapse should balance speed with accuracy to avoid both under- and overtriage. Establish a clearly labeled treatment area near the scene but outside immediate collapse risk, with defined zones for primary and secondary assessments, treatment, and temporary holding. Track patient counts by category, assign unique identifiers, and document time stamps for each triage and treatment action. Coordinate bed availability, transport units, and receiving hospitals in real time, and set clear criteria for when to request mutual aid or additional specialized teams.
Sample metrics for scene triage
| Metric | Estimate or Range | Context |
|---|---|---|
| Initial scene safety assessment time | 3–10 minutes | Until hazards are confirmed mitigated |
| Time to first patient contact (ideal) | From command establishment to treatment start | |
| START assessment time per patient | 20–60 seconds | Simple adults under ideal conditions |
| Recommended provider-to-patient ratio (light triage) | Varies by acuity and environment | |
| Transport request lead time | Before patient handoff, when possible |
Communication, documentation, and handoff
Clear communication supports safe triage and transfer of care. Use plain language, standard terminology, and closed-loop communication with dispatch, hospitals, and on-scene command. Relay patient counts, triage categories, resource needs, and expected transport times for each batch. Maintain concise, factual documentation using event time logs, patient identifiers, and triage colors. Provide concise handoff reports that include mechanism, vital signs, interventions, time of last oral intake, and special clinical concerns such as entrapment times or suspected crush syndrome.
Ethical, legal, and psychological considerations
Clinicians working mass-casualty incidents require guidance on ethical frameworks and legal protections. Use objective, evidence-based triage criteria, apply resources fairly, and avoid discrimination based on age, comorbidities, or perceived prognosis. Document decisions and rationales, follow Good Samaritan and disaster liability laws where applicable, and access critical incident stress support for providers. Coordinate with incident command to balance clinical priorities with organizational policies, media interactions, and community expectations.
Post-event evaluation and continuous improvement
After the scene is cleared, conduct a structured after-action review with clinical, operational, and command stakeholders. Compare triage decisions, transport times, and outcomes against benchmarks and hospital feedback. Identify gaps in equipment, training, communication, or zone setup, and update protocols, checklists, and rehearsed drills accordingly. Maintain an evergreen lessons-learned register so that each incident improves future responses and reinforces high-information, low-risk practices for providers and survivors.
While triaging patients at the scene of a building collapse is high-stakes and time-sensitive, a durable, principle-based approach to scene safety, triage systems, communication, and ethics supports consistent, defensible decision-making. By grounding actions in verified protocols, clear documentation, and coordinated command, clinicians and responders can optimize outcomes for patients while protecting providers and maintaining public trust across varied structural failure scenarios.
