It's always surprising to me how fall risks operate in the world of OSHA compared to rock climbing. There's an entire domain where people take good-sized falls as an everyday event, just sort of sitting in parallel with the domain where they're considered a major risk needing emergency-response measures.

Obviously, some of that is a real difference in situation. Construction falls are unplanned and happen under all sorts of odd circumstances, and people are quite often injured during their falls. Climbers have someone managing the other end of their rope at all times, on a system that makes lowering them to the ground straightforward.

But other differences seem absolutely pointless. The "suspended by your groin, legs hanging straight down" posture of construction harnesses massively accelerates suspension trauma, while climbing harnesses pull the legs up and keep pressure on large muscles. And there are companies starting to use that design for safety gear, so it's not a regulatory issue - it just somehow took decades to cross the gap.
