What are the mass casualty triage color tags?

The START (simple triage and rapid treatment) system is widely used for response to a mass casualty. First responders bring victims, who are placed in one of four categories: BLACK (deceased/expectant): Injuries are incompatible with life. Should not be moved forward to the collection point. RED (immediate): Severe injuries but high potential for survival with treatment. First to be taken to the collection point. YELLOW (delayed): Serious injuries, but not immediately life-threatening. GREEN (walking wounded): Minor injuries.
