Final answer:
The fall arrest component that distributes the arresting forces of a fall across the shoulders, thighs, and pelvis is the full-body harness.
Step-by-step explanation:
The fall arrest component that distributes the arresting forces of a fall across the shoulders, thighs, and pelvis is the full-body harness.
A full-body harness is designed to protect the wearer in the event of a fall by spreading the impact forces across the shoulders, thighs, and pelvis. It consists of straps and buckles that secure the wearer and provide attachment points for other fall protection equipment.
For example, if a person falls while wearing a full-body harness, the force of the fall is distributed across these areas of the body, reducing the risk of injury.
