FALL PROTECTION ANCHORS
FALL PROTECTION ANCHORS
(OP)
Hi, One of our contractor suggested to install fusion roof anchors instead of the conventional fixed davit posts for fall protection. The advantage of using this anchor is the tension force in the attachment system to roof structure is not a lot as the fusion post will tip over at 1000 lbs. and will load parallel to the roof beyond 1000 lbs. you may refer to the following for a typical product. Does anyone have experience with this type of product? Did you ever install this product in any of your project?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

This was years ago but from what I recall, the light gauge deck/standing seam roof installation works well but if someone falls and it is engaged, the roofing/deck is basically destroyed. You have to replace the panel afterwards.
I'm sure the person who this is saved by will be quite thankful it works but I doubt the building owner will be too happy about fixing the roof. They didn't tell us that until we spoke with a rep.

Thank you. Good information. I don't know the anchor posts need to be replaced too after it engaged each time? However, I am not sure about the 5000 #s load capacity will be achieved as OSHA requires.

The 5000# rule comes into play when you have a rigid element that you're tying off to. Think your typical post welded to an embed plate on a concrete roof. That has to be designed for 5000# because it has no other means for dissipating the energy.
I did not end up recommending using those anchors. It was mostly cost related reasons. We designed a rigid element for the 5000# requirement.
I'm not saying the Miller product is bad. It's tested and I'm sure works just fine for protecting anyone tied off to it and definitely has applications where it works best (like existing structures). I suggest getting in touch with one of their reps and learning the pros/cons of their product so you can, at the very least, be informed for the client and make a good recommendation.
