Tying off the PIRANA

There are several types of tie-off, the choice of which depends on the situation (rappelling with feet supported, or free-hanging), and/or on the maneuvers to be performed:

1. Temporary stop

You must keep a hand on the brake-side rope.

2. Long duration tie-off

Here are two tie-offs that allow both hands to be free, with maximum security. The second tie-off is not recommended for free-hanging rappels because it can be difficult to undo, which is problematic on a waterfall rappel. Always keep your body weight on the rope.
