What is the proper order for securing straps during a spine boarding procedure?

The proper order for securing straps during a spine boarding procedure prioritizes maintaining spinal alignment and stability. Securing the upper chest first is crucial as it helps prevent the patient's torso from moving, which could exacerbate any potential spinal injuries. Following this, securing the hips provides additional stability by anchoring the middle of the body, which is critical for maintaining a safe position. Finally, securing the thighs ensures that the lower body is stabilized. This sequence minimizes movement and maintains proper alignment, crucial for preventing further injury during transport.

In contrast, other sequences either start with less critical anchoring points or do not provide the same level of immediate stabilization needed for the chest and hips. This could lead to potential movement that compromises the safety of the patient.
