Specific Scaffold – §1926.452(a)Pole Scaffolds

Pole scaffolds are a type of supported scaffold in which every structural component, from uprights to braces to platforms, is made of wood. OSHA has standards for two kinds: single-pole, which are supported on their interior side by a structure or wall, and double-pole, which are supported by double uprights independent of any structure.

Because they have to be built from scratch and cannot easily be reused, pole scaffolds are considered old-fashioned and are rarely used today.

  • When platforms are moved to the next level, the existing platform must be left undisturbed until the new bearers have been set in place and braced
  • Where wooden poles are spliced, the following regulations apply
    • The ends must be squared
    • The upper section must rest squarely on the lower section
    • Wood splice plates or scab plates must be provided on at least two adjacent sides, and must:
      • Extend at least 2 feet on either side of the splice
      • Overlap the abutted ends equally
    • Have at least the same cross-sectional areas as the pole.
    • Splice plates made of materials other than wood may be used, as long as they are of equivalent strength
  • Pole scaffolds over 60 feet in height must
    • Be designed by a registered professional engineer
    • Be constructed and loaded in accordance with that design.
