First on scene at a scooter crash at dusk
At 21:50 on a dark rural road a rider comes upon a crashed scooter. The scooter lies in the ditch, its headlight still on. The scooter rider, a man in his 30s, is lying on his back on the asphalt, unconscious but breathing noisily. He wears a full-face helmet with the visor up, a textile jacket and jeans. Blood is pooling under his right lower leg, and his left arm is bent at an unnatural angle. There is no oncoming traffic at the moment, but the road curves just before the scene. The rider has a first-aid kit, a mobile phone and a hi-vis vest. Another car has stopped 50 m away.
1. What are the first actions the rider should take on arriving at the scene?

The first priority is not the casualty; it is not becoming a second casualty. The rider should stop before the scene, switch on hazard lights, put on the hi-vis vest, and position the motorcycle so it protects the casualty if that can be done safely. The other car can be asked to put on hazard lights and warn approaching traffic from the curve. The rider should call 112, give the exact location, say that a scooter rider is unconscious but breathing, and describe the leg bleeding and the arm injury. The rider should not move the casualty unless there is an immediate danger such as fire or traffic. The helmet should be left on for now. The rider should check breathing and responsiveness, note the time, and keep talking to the casualty even if he does not respond. If other people arrive, the rider should give them specific tasks rather than letting them crowd the casualty.
2. Should the rider remove the helmet? Explain how to decide and what to do if removal is necessary.

The helmet should normally be left on. Removing a full-face helmet from an unconscious crash victim can move the neck and worsen a spinal injury. The exception is when the helmet blocks the airway or makes effective breathing support impossible, for example if the casualty is vomiting, has noisy breathing that is not improving, or needs CPR. In this scene the breathing is noisy, so the rider should first check whether the airway is obstructed by blood, vomit or the tongue, and should be ready to act. If removal is necessary, it should be done by two people: one kneels at the casualty's head and holds the head and neck steady, while the other gently widens the helmet and rolls it forward and off, avoiding twisting. If the casualty stops breathing, call 112 again or update the dispatcher and start CPR. The rider should not remove the helmet simply to see the face.
3. How should the rider control the leg bleeding and manage the casualty until the ambulance arrives?
Read the worked answer
The rider should put on gloves if available and apply firm direct pressure to the bleeding wound with a clean dressing from the first-aid kit. If blood soaks through, add another dressing on top rather than removing the first one. If the leg is not obviously deformed, raising it slightly may reduce bleeding, but the rider should not move the leg if a fracture is suspected. The rider should check that the foot is warm and has a pulse if possible. For shock, the rider should keep the casualty warm with a blanket or jacket, reassure him, and not give food or drink. The rider should monitor breathing and responsiveness continuously and be ready to turn the casualty into the recovery position if he vomits, while keeping the head and neck aligned. The arm injury should be supported, not straightened. When the ambulance arrives, the rider should report what was seen, what was done, and the time.
