Iron worker setting beams and such? Know some about it. Can be very dangerous work if your clumsy and/or scared of heights. Every thing you work with can crush, kill, or maim you in a instant. You will have to walk beams, lean over them to place bolts, align them with a spud, slight welding will be part of it also, along with primering the weld spots. Pension is one of the best if its a union job. Its a labor intense job.
Trip and fall 100ft up, well, it's only a 8" wide sidewalk up their, nuff said.
