What is the requirement for a worker in fall arrest regarding attachment points?

The correct answer is that a worker in fall arrest requires one point of attachment. In fall arrest systems, the attachment point is a crucial component that ensures a worker is safely secured to their harness and the anchor point. A single, properly installed point of attachment is sufficient as long as it meets the required safety standards and is correctly utilized.

This single attachment lets the system arrest a fall effectively, provided it is designed for the weight load and other conditions of use. It's essential for the attachment point to be located above the worker to minimize the distance of a potential fall and reduce the impact forces experienced by the worker.

More points of attachment, while they can offer redundancy, are not necessary for achieving the primary goal of fall arrest, which is to prevent a fall from occurring in the first place. Hence, the focus is on the strength and integrity of that one point rather than the quantity of attachments, emphasizing the importance of understanding and following safety protocols correctly.
