We are working on an industrial site (IU-2 & IU-3, H-3). We have a fixed ladder that goes from the ground floor slab to a catwalk that is 65 feet above the slab.
-How many platforms do I need? What is the max spacing from ground, from catwalk...and in between?
-a 36"x36" platform is sufficient, right?
-Does the platform need a safety gate to the ladder?
