Four colours sorting casualties by urgency at an incident.
Also known as: Triage categories, Casualty sorting tags
Triage tags sort casualties by four colours: red for immediate, yellow for delayed, green for walking wounded and black for expectant or dead. The black category is the one that makes triage different from ordinary care — it identifies people who will not be treated first because resources are limited.
Sort casualties at a mass-casualty incident into four categories by colour, from immediate through delayed and minor to expectant.
Contexts: Medicine
Include an expectant category precisely because triage operates where resources are insufficient, which is the feature that distinguishes it from ordinary clinical prioritisation.
Contexts: Medicine
Vary in their exact schemes between countries and services, so the colours are near-universal while the sorting criteria behind them are not.
