Where are the attachment points of a full body harness located?

The attachment points of a full body harness are primarily located at the center of the wearer's back between the shoulders and often above the head. This position ensures that, in the event of a fall, the harness can effectively distribute the forces across the body, particularly around the shoulders and back, minimizing injury risk.

By having the attachment point positioned on the back, it allows for greater mobility and helps prevent the wearer from flipping upside down in case of a fall, which can lead to serious injuries or difficulty in breathing. The design and placement of these attachment points are critical for ensuring the harness functions correctly during a fall, providing the safety that workers need when working at heights.

Other placements, like those indicated in the remaining choices, do not provide the necessary support and safety features that a central back attachment can offer, making option B the most effective and correct location for attachment points on a full body harness.
