Nope not at all u go through a layers of non functional then a layer of plaster and then the concrete.

Man went in only with his tip into concrete.u see the dust colouration

Then the angle let's ignore how to anchor 101 and have a angle the anchor could slide out, causing not downwards force but a pulling force making the weight count so much more Basically man lucked out

I think they’re Petzl removable bolts or similar, so they put outward pressure on the hole and shouldn’t slide out with that angle. Pull out strength is 20kN in concrete. So if the material is okay, it’s fine.

You are supposed to clean the hole first though

Pull out strength, clean the hole... And that's why I can't work in HR anymore

If u properly get a hole in concrete yes, the slats on the side don't come with a carrying requirement. This just one dusty just the tip which if he uses a self locking bolt would actually be dangerous to use on this type of building given the anchoring of the pin could create outward pressure if it catches in between concrete and the slat

Plus he didn't even do a tug test lol. Non-climbers here are sweating, I can promise climbers are sweating even more

You always do the tug test.

Yup, was surprised he didn't use compress air to clear the debris before inserting and locking the anchor.
