Backup line, shown in blue to the right, configured for self belaying.

A second rope used in addition to the working line with a dual rope system. This may be used like a lifeline, with a belayer. Alternatively, it might be a fixed rope hung next to the working line, used with a self belaying technique, such as using a fall arrester. With rope access, it is most commonly used with self belaying, and the fall arrester would normally be required to move up and down the rope without needing to be held in a hand, to avoid being gripped in panic during a fall.
