When there are more casualties than first aiders, a system of determining priority of treatment is required known as Triage.

Triage is the process of determining the priority of patients based on the severity of their condition.

Generally, an unconscious victim takes priority over other victims.

In an emergency situation, first aid trained people can use a simple triage system known as Simple Triage and Rapid Treatment (START) as per the following chart.

The goal of triage is to achieve the greatest good for the highest number of injured persons.

During the initial stages of a multiple casualty incident, first aiders may be overwhelmed by the scope of the casualties and injuries and as the head first aider it is vital to show leadership.

Try to remain calm and reassure the team.

Never assume that every team member is okay and knows what they need to do.

Give clear and precise directions to minimise confusion and anxiety.

Effective leadership will instil confidence that the incident is effectively managed.
