Fixed ladder
Fixed ladder
(OP)
Dear all,
while designing a fixed ladder for a distillation column, I´ve seen a reference in the pressure vessel handbook of ANSI A14.3 but only one page is shown, does anyone have a copy that could facilitate me or know where I could download a copy of the entire standard?
Thanks a lot

RE: Fixed ladder
Based on the limited information you have given us it would appear that what you described will work and will not violate common sense.
Most of the vessel orientation I have done was based on USA OSHA Codes, Standards and Guidelines.
They limit the vertical length of a single ladder to 30'. Then you must step off on a platform and approach the next ladder.
This makes good sense when you have spent time in the field and had to climb some of the Real Old vessels which have one ladder from grade to the top (150 to 200 feet or more).
You get tired and run the risk of falling if there is no mandatory place to step off to rest. Falling 30 feet down a caged ladder might result in some bruises and maybe a broken arm but 150 feet will spoil your whole day.

I wanted to know if someone has a copy of A14.3 and could send it to me.
