What drag is preferred when pulling victims down stairs to protect their head?

The preferred method for pulling victims down stairs to protect their head is the head first drag. This technique minimizes the risk of injury to the victim's head, as it allows for better control and positioning during the descent. When using a head first drag, the victim's body is kept close to the ground, which helps to prevent their head from hitting the stairs or any obstacles along the way.

In contrast, dragging a victim feet first can expose their head to potential impacts, particularly if the stairs are uneven or if sudden movements are required. A sideways drag may not provide adequate support or control, increasing the risk of the victim's head leading towards the stairs during the movement. Pulling by the arms does not provide enough stability and may lead to further injury as it doesn't adequately protect the head and can exert unnecessary strain on the victim's shoulders and neck.

Thus, the head first drag is the safest option for ensuring the head remains protected during a descent down stairs.
