Should You Always Use Safety Backups With Figure-Eight Knots?

Understanding the Figure-Eight Knot Family

The figure-eight knot family, including the figure-eight follow-through and figure-eight on a bight, is a reliable choice for securing loads, creating a secure loop, or making a lashing. However, its security relies on proper tying and tensioning. In high-stress environments, such as rock climbing, sailing, or rescue operations, a safety backup is crucial to prevent accidents.

Implementing Safety Backups with Figure-Eight Knots

When using figure-eight knots, a safety backup can be achieved by adding an additional knot, such as a bowline or a round turn and two half-hitches, to the standing part of the rope. This ensures that even if the figure-eight knot fails, the additional knot will hold, preventing the load from falling. For example, adding a bowline to the standing part of a climbing rope can provide a secure backup in case the figure-eight follow-through fails.

Techniques for Creating Safety Backups

To create a safety backup with a figure-eight knot, start by tying the figure-eight knot and then add the additional knot to the standing part of the rope. Ensure that the additional knot is tied snugly and evenly spaced from the figure-eight knot. This will provide a secure backup and prevent accidents in high-stress situations. For example, a round turn and two half-hitches can be added to a figure-eight on a bight to create a secure backup, while a bowline can be used to create a backup for a figure-eight follow-through.
