Final answer:
The disaster tag system mentioned in the question is a triage method used in EMS during major incidents to categorize patients by injury severity for effective management.
Step-by-step explanation:
The disaster tag system referred to in the question is likely a part of the triage process used by emergency medical services (EMS) during a major incident. This tag system is designed to quickly categorize patients based on the severity of their injuries and the immediacy with which they need medical attention. In most triage systems, color-coded tags are used: red for those who require immediate attention, yellow for those with serious but not life-threatening injuries, green for the walking wounded or minor injuries, and black for those who are deceased or beyond help. The Quick Assessment and Execution of Multiple Patients System (QAEMS) might integrate such a tag system for efficient victim management during a disaster.
