D = Check for Danger
Protect yourself, bystanders and the casualty from further injury.
DO NOT APPROACH IF TOO DANGEROUS
For example an area with an explosive potential or close to fallen power lines. Maintain a safe distance, call emergency services (000) and warn others of the danger.
If the danger can be managed, then initially aim to remove the danger or, if this is not possible, then move yourself and the casualty to a safe area as quickly as possible. If an injured person cannot shift themselves independently you could attempt to drag the person, by their feet or arms, to a safe area. Ideally avoid bending, twisting or carrying the casualty.
