Saftey Anchors built in to walls

This was on the news last night. This strap is looped over the rebar prior to the pour. The bigger jobs would have these straps everywhere. When done cut them off.

I'm confused - the lit says the minimum breaking strength is 5,000 pounds AND that its capacity is 450 pounds. What am I missing?

MY understanding is: that is the max weight load for the 'D' ring. If this is your business you must have figured a way to re-use them after cutting them. I would have new straps sewn on, lots of 'Omars' around here.

Used all the time in high-rise construction, then the straps are cut off when no longer needed.

The 450 pound limit is the worker and tools, the 5,000 pound minimum breaking strength is to cover stopping that worker at the end of the OSHA limited 6 foot fall. I don't know what the math is, but 450 pounds falling 6 feet is quite a bit of weight to be stopped at the end of that 6 foot fall, even with the deceleration affects of the tether.

By the way, when a worker falls and is hanging in the harness, the instructor at my fall protection class said that the harness begins to cut off the block blood circulation within 2-3 minutes of hanging there - so they need to be rescued rather quickly to keep from having permanent damage from loss of blood circulation, much less from the fall.

Highest buildings around here are on the farms. My town has one building over two stories, its 2.5... Until we can afford fire/rescue to those higher elevations we will continue to use the old stand-by:Yelling Jump! we'll catch you....
Rescue Drills would obviously be in place, so, the casualty shouldnt be hanging to long. The simple things.
