When should a rescuer use a figure-eight on a bight?

A figure-eight on a bight is specifically designed to create a secure loop in the middle of the rope, which makes it an ideal choice for anchoring or rigging. This knot allows the rescuer to effectively utilize the strength and safety of the rope without needing two free ends, as it can be tied in the bight of the rope itself.

This capability is particularly beneficial during rescue operations when a stable and reliable loop is necessary for securing lines or creating systems that will support loads and provide safety. The figure-eight on a bight maintains its shape, does not slip under load, and is easily untied after use, making it practical for dynamic rescue situations.

Other options do not appropriately apply to the use of a figure-eight on a bight. For example, securing rescue gear to a vehicle generally requires knots that provide secure ties or lashings rather than loops in the rope. Similarly, when creating a descending device, other types of knots or configurations are more suitable. Tying off a rope to a fixed point typically involves different anchoring techniques that focus on the security and stability of the connection rather than creating a mid-rope loop.
