How many patients typically define a Level 1 multi-casualty event?

A Level 1 multi-casualty event is typically defined as involving 5 to 10 patients. This designation is based on the incident's potential impact on medical resources, requiring a coordinated response from EMS and other agencies. At this level, numerous patients may need medical attention, but the situation is still manageable with standard emergency protocols and local resources.

In multi-casualty incidents, the classification helps determine the necessary response and resource allocation. By identifying a Level 1 event, responders can initiate triage procedures to prioritize care based on the severity of injuries and the extent of resources required. This structured approach ensures that those most in need receive timely assistance while adequately addressing the needs of all patients involved in the incident.
