During triage, as a minimum, the patient number, the sighting category, the time, the name of the examining doctor and a brief diagnosis must be recorded on the casualty tag. The sighting categories are usually pre-printed and only need to be ticked. In order to recognise the status of the patient even from a distance, new cards are equipped with a colour card. Here, red stands for category 1, yellow for 2, green for 3, blue or grey for 4 and black for deceased.
