can u spot the safety issue ...

Outstanding chair and it is made from woven climbing rope. That said should be attached to the wall with equalized weighted slings or a length of climbing rope.

Love all the techy answers. But the obvious answer is she didn't floss. People who don't floss have a life expectancy ten years earlier than those that floss. Opera said so.

OH MY GOD SHE'S NOT WEARING A HELMET!!!

I call BS on people wagging their finger at the the nylon sling. I've taken factor 1.5-2 falls onto a spectra daisy while aid climbing, and my giblets are just fine. I've got the empty whiskey bottles to prove it too.

Lewd? Dude!! You ain't heard lewd. I thought people were being rather respectful.

Cute girl. Looks like ultimate hanging belay seat for sure, now I know what my next project is for more old footage of retired climbing ropes laying around here.

Pedantic me says that since she is sitting so far away from the wall, the chair wants to pivot around those legs. This means they are putting a lot of outward pull on the bolts (not designed to do that). Quick math: Girl + gear + chair = ~180lbs Distance from center of mass of girl/chair from wall = ~3ft Distance from bottom of legs to anchor bolts = ~6ft 3ft*180lbs = outward pull on each bolt*2*6ft outward pull = ~ 45lbs per bolt. Too much? If she jumps up and down on the chair, outward pull = 100++lbs per bolt Rule #1 of posting new and interesting pictures to Mountain Project: NO FUN ALLOWED.

Have you never climbed a bolted roof or overhanging route? Bolts are fine in pull out as well as shear strength...

Alex - that may be an over generalization. While I agree with you mostly, there is a large distribution in bolt strength in perpendicular tension (due to bolt type, installation expertise, age, etc etc) definitely much weaker in that direction.

That said, Page failed to notice that only one of the upper bolts is in tension (the other appears to be in pure shear)....still not enough to worry about.

And Bearbreeder's fear of a shock load on a biner due to the sling is unfounded because the entire chair is a spring steel shock absorber - the leg on the fall side will deform and absorb the energy, as will deformation of the chair frame.

Definitely much weaker? That is not really true. The difference between shear and tension is often quite negligible for many anchors.

(~10% isn't what I call 'much weaker')
(Fixe, is 22kN vs 15kN)

There's endless "cool" photos of idiots taking far greater risks, with no protection at all, such as the one below. These folk obviously haven't read the accident statistics for falls unroped.

Sorry, but yer way off base here. The shear strength is almost always greater than the pull out strength. Educate your self a bit. Start here for a primmer:

I think you should re-read what he said. He never said pull-out strength was equal to or greater than the shear.

I saw this on FB - responded to same effect: Saftey issue- I am sitting here looking and my wife asks "Why are you staring at that picture for so long?"
Not dangerous in and of itself, but I have a problem - a dry sense of humor with no filter - and so it's like a choose your own adventure book.

That dude is up on the troll's tongue in Norway, not too far from Voss. Was just there last summer visiting Joseffa:

Yeah yer right ... misread

It depends on the bolt type. Sometimes 3/8" wedge bolts are stronger in tension than shear. For example, the 3/8" Power-Stud carbon steel bolt is rated for 27kN in tension and 23kN in shear. The Hilti Kwik III 3/8" carbon steel bolt is rated for 28kN in tension and 20kN in shear.

Interestingly, once we reach a stud diameter of 1/2", the differences tend to mellow out, and once we reach a stud diameter of 5/8", the bolt becomes stronger in shear than tension. With regard to sleeve bolts, such as the 5-piece, the bolts tend to be stronger in shear regardless of diameter. Also, wedge bolts tend to be stronger, regardless of diameter, in shear if the bolting medium is soft and the bolt is short (e.g. 2,000 PSI). But in that application the mode of failure is often the rock and not the bolt.

This is the biggest issue I could see.
