Work Area Circulation Paths: Exceptions

Common use circulation paths are required to be accessible except:

  • in work areas below 1,000 sq. ft. in size

  • in work areas fully exposed to the weather (regardless of size)

  • where they are integral to work equipment

Large tanks with stairs leading to catwalk on top. Figure note: Circulation paths integrated into storage tanks, machinery, and other work equipment are not required to comply. Technical exceptions also allow circulation path clearances to be reduced where it is essential to the work function (§403.5, §405.5) and permit later installation of ramp handrails (§405.8).
