Final answer:
In an accident scene without a CB radio, prioritize your safety, assess the situation, and call emergency services if needed, rather than attempting a rescue yourself unless you are trained.
Step-by-step explanation:
In the absence of a CB radio at an accident scene, your first action should be to ensure your own safety and then evaluate the situation without moving or causing further harm. If you have not been trained in providing medical assistance or if the scene is potentially dangerous, do not attempt to rescue victims or administer first aid. Instead, take note of the situation and as soon as it is safe to do so, call for emergency services to handle the rescue and medical care. Observing your surroundings is crucial, and if you are unable to help directly, find an adult or authority figure who can assist or call for help. Remember, your safety is paramount, and trained professionals should handle potentially dangerous rescue attempts.
