From rapid triage to seamless inter-agency coordination, EMTs are vital in managing chaos and saving lives during mass casualty incidents. Here’s what every EMT should know.

 

 

1. Understand the Definition and Scope of an MCI

• The actual definition of Mass casualty incidents (MCIs) can vary depending on the EMS agency. The severity of an incident is affected by the number of patients, and the number of EMS resources available in the area.

• Examples include natural disasters, terrorist attacks, active shooter situations, and large-scale accidents.

• EMTs Learn to adapt their priorities in mass casualty incident scenarios..

 

 

2. EMTs are taught to "triage patients.” The “START” Method of triaging patients is a common format to use. 

• START (Simple Triage and Rapid Treatment) is the most commonly used triage system in MCIs.

• Based on several quick assessment findings, patients are categorized into four groups: Minor (Green), Delayed (Yellow), Immediate (Red), and Deceased/Expectant (Black).

• The brief assessment focuses on respiration, perfusion, and mental status. “RPM”

 

 

3. Maintain Scene Safety and Situational Awareness

• EMTs must not rush into unsafe zones; scene size-up and seen safety is an ongoing process that all rescuers on scene participate in.He heCollaborate with incident commanders and law enforcement to assess hazards.

• Situational awareness is being constantly vigilant and paying attention to changes that may be taking place on the scene. EMTs are trained to be proactive and prevent problems from occurring whenever possible.

 

 

4. Coordinate Within the Incident Command System (ICS)

• EMTs must operate under the ICS structure to ensure organized response.

• This includes reporting to a Medical Branch Director and following defined command roles.

 

 

5. Communicate with Other Agencies Seamlessly

• Effective interoperability between EMS, fire, police, and hospitals is essential.

• Use clear radio communication and follow mutual aid agreements.

• Participating in pre-incident planning and drills with other response teams is important for practice and to develop appropriate procedures and identify areas of weakness before an actual emergency takes place.

 

 

6. Implement Casualty Collection Points and Transport Zones

• Zones will be established for initial patient treatment and staging.

• Patients will  flow from triage treatment and then to transportation.

• EMTs will be working with transport officers to avoid overwhelming hospitals.

 

 

7. Use Triage Tags and Patient Tracking Systems

• Triage tags are used to identify a patients category and condition.

• Electronic tracking systems may be used to relay patient data to hospitals.

• Vital signs and interventions can be added on the tags when possible.

 

 

8. Prepare with Regular Drills and Tabletop Exercises

• EMTs may participate in multi-agency drills simulating various MCI scenarios.

• Drills improve speed, accuracy, and familiarity with triage systems.

• Identify operational gaps and review after-action reports post-exercise.

 

 

9. Analyze Lessons Learned from Past MCIs

• Review high-profile MCI case studies like the Boston Marathon bombing or Las Vegas shooting.

• Analyze what strategies worked, what failed, and what was improved post-event.

• Incorporate those findings into local protocols and training.

 

 

The role of EMTs in mass casualty incidents is complex, demanding, and critical. From accurate triage to seamless interagency coordination, every second counts. Preparation, education, and communication are the key pillars that empower EMTs to lead under pressure and save lives.
