Scope
This standard specifies the safety design specifications for industrial staircases, work platforms, and walkways.
This standard applies to industrial staircases, work platforms, and walkways used as fixed facilities for entering machines.
This standard also applies to industrial staircases, work platforms, and walkways that are not fixed to machines, but may need to be removed or moved to the side when performing certain operations on the machines (for example, replacing tools on large presses).
Other industrial staircases, work platforms, and walkways can also be used as reference.
