Unsafe for what? Almost all of the fall forces should be dissipated by a dynamic rope, not the harness.

- bhickey 9y agoVery high factor falls. A factor 2 fall can kill you even if you don't hit anything on the way down.
- yan 9y agoIf you're healthy and using a normal, dynamic rope, no it won't. It won't even hurt. A factor 2 fall onto webbing or dyneema can totally mess you up though, even from a couple of feet.
- bhickey 9y agoTake a 60 foot 1.95 factor fall and get back to me.
- steveax 9y agoYou'll want to retire that rope, but nope, I've had a couple of high fall factor falls with no ill effects. A true fall factor 2 fall is impossible to achieve in a real setting (knot, etc.), but I've taken a prob 1.6 or so.
- blackguardx 9y agoThe UIAA (climbing standards body) disagrees with you. The specs of climbing ropes are set by them to result in no injury in worst case falls. And plenty of people have taken factor 2 falls with no ill effect.
- bhickey 9y agoAnd industrial fall arrest literature disagrees with the UIAA. A 4kN loading will break your spine in the correct orientation.
- blackguardx 9y agoWorkplace exposure limits are always lower than injury thresholds.
