Carabiners / Harness connection

There is a right way and a wrong way to connect a carabiner to a harness, the gate of a carabiner should always face outwards, never against the body. If the gate is innermost, the top of the gate itself can get trapped on the suspension point which creates a lot of stress on the gate itself, typically damaging it and preventing its removal once the entrant is at the bottom of the chamber.
