Ladders platform

Distillation is the dominant separation process in the petroleum and chemical industries. It is carried out continuously more often than batchwise, in large, vertical, hollow cylindrical columns (or towers). Figure 1 shows a large distillation column with its associated piping, heat exchangers, vessels, ladders, platforms, and support structures. Figure 2 shows a simple schematic representation.

Ladder/Platforms Meet OSHA Standards AS. 4/13/07 OPEN ... 

Fixed ladder platform requirements are outlined at 1910.27(d)(2). Specifically, OSHA requires that platforms be provided for each 30 feet of height if the ladder has a cage. However, if the fixed ladder does not have a cage, then a platform must be provided every 20 feet. OSHA requires a fixed ladder platform be at least 24 inches wide and 30 inches long. 

What fall protection is required for fixed ladder platforms ... 

Fixed ladder platforms must have a standard railing and toeboard, so arranged as to give safe access to the ladder, per 1910.27(d)(2)(ii). 

Devices can be built into stacks to counter the vortex shedding, which causes dynamic instability. Helical vortex strakes are the most common and practical vibration inhibitors for stacks. They are generally too awkward to use on process columns because of external attachments, such as ladders, platforms, and piping.
