In NYC, what knot is required to anchor all safety lines?

• A. Bowlines
• B. Clove hitch
• C. Figure-eight
• D. Double overhand

Answer: (A)

The main idea is using an anchor knot that stays secure under load and is easy to inspect. For anchoring safety lines, a figure-eight knot (such as a figure-eight on a bight or a figure-eight follow-through, depending on the setup) is preferred because it forms a fixed, non-slipping loop that won’t pull loose as forces act on the rope. It’s reliable when the rope is loaded from different directions and remains easy to untie after use or an incident, which is crucial on job sites. Why this works well: the figure-eight shape resists shifting and slipping, provides a clear visual dress of the knot, and doesn’t easily capsize under dynamic loads. In contrast, a bowline can loosen under heavy load without extra backups, a clove hitch can slip if the anchor moves or the rope shifts, and a double overhand can jam and be hard to untie after loading. So the figure-eight is the safest, most dependable choice for anchoring safety lines.
