Remember that your behaviour at the scene of an accident will directly influence the actions of the other people present. Be aware of your own safety at all times. Double-check that vehicles, machinery and smokers involved in the accident pose no further threat. Be mindful of spinal injuries. Do not move injured patients unless their lives are in immediate danger. Never leave an unconscious patient's airway unsupervised. If a motor cyclist's helmet is removed, it must be done slowly and smoothly.
