I'm not actually sure who took the photo's.
They were posted at a Occ Health and Safety Forum in Australia.
The thing I'm thinking with the bottom pic is this:
How did they get that scissor lift up there, in the first place?.
Also, I'd sort of hope that that section of lean-to roof, is well anchored to the wall of the building!.
One last point, I can't help but think, that there is some sort of an exit/entry/fire escape to the left of the pic, that's been covered up by a new sheet of siding, where that ladder goes through the roof of the lower section.
Anyone else get that feeling?.
