Look around and check the area around the casualty for any risks or signs of danger. Example dangers could be any moving traffic nearby, boiling water, electrical current, chemicals.

If it is a car accident, turn off the ignition to reduce the risk of a spark causing a fire.

Ask bystanders to warn approaching traffic (standing in a safe place), put out a warning triangle and call an ambulance.

This could be as simple as moving a sharp knife or a fallen chair out of the way or switching off a cooker or a plug socket.

Quickly remove any hazards, without putting yourself in danger.

Administer appropriate emergency aid for the injury, e.g. for a burn immerse the burned area in cold water, clean and dress a superficial graze. Attempt only what you know can be done safely.
