Which of these is NOT a good rule to follow when caring for the injured at an accident scene?

When caring for the injured at an accident scene, maintaining the proper body temperature is crucial for their recovery and overall well-being. Keeping injured persons warm is important, especially in situations where shock may set in or if they are exposed to the elements. Cold conditions can exacerbate injuries or lead to hypothermia, which can be life-threatening.

Calling for professional medical help, as well as comforting and reassuring the injured, are also essential actions to ensure their safety and improve their chances of recovery. These focus on providing immediate assistance and emotional support, both of which are critical in emergency situations.

In contrast, aiming to keep injured persons cool is generally not advisable, as it can lead to complications and worsen their condition. Hence, it is not considered a good practice in the context of caring for the injured at an accident scene.
