Which type of injury would receive a black tag during a mass casualty incident?

In the context of a mass casualty incident, a black tag signifies that the patient is not expected to survive given their injuries and the resources available for treatment. This system is part of triage methods used to prioritize patients based on the severity of their conditions.

Full-thickness body burns covering 80% of the total body surface area are among the most severe injuries a person can sustain. These burns affect multiple bodily systems and can lead to shock, infection, and organ failure. The extensive nature of the burns significantly challenges the body's ability to survive without immediate and comprehensive medical intervention, which may not be feasible in a mass casualty scenario where resources are limited and many patients require urgent care.

Thus, patients with such critical injuries are typically given a black tag to indicate that they are unlikely to survive even with medical intervention. Triage decisions focus on giving priority to those who have a better chance of survival, which is why other injuries like a fractured wrist, minor lacerations, or a concussion would not be categorized in the same way. These injuries, while requiring attention, do not pose the same immediate life threat as severe burns covering such a vast area.
