Does anyone know if standard climbing harnesses (not chest harnesses) are actually rated (e.g. tested and certified) for use in upside down falls?
Obviously falling upside down is a bad idea, and we should avoid it for many good reasons.
But I sometimes playfully flip upside down while being lowered on toprope. I was recently queried about the safety of such antics.
I've been climbing a long time, and never had any reason to think that I could slip out of the harness from hanging (or falling) upside down. But a question of safety always bears analyzing. And I couldn't immediately reference anything authoritative on the question.
Extra points for any references to published tests of harnesses in upside down fall conditions.
