Rock climbing is a hugely popular hobby around here. Might be around
there too.
You can probably buy industrial safety equipment as well, made
specifically for that job, but the climbing stuff works as well. When
climbing you "fall" every day if you are pushing your limits, so the
protection works.
Just a harness that goes on you, and then a rope, and then a gizmo
that attaches to your harness. As you climb, you pull the slack through,
but if you suddenly fall, it snaps onto the rope and holds you. You can
also let yourself down in a controlled manner with a small brake on the
rope.
Unsure how much it might cost you to get started. The rope is
expensive because it has some "give" to it. You are supposed to throw
the rope away if you take a good fall with it.
