Dear Mr. Almony:
This is in response to your fax transmission of September 4 to the Occupational Safety and Health Administration (OSHA) in which you asked about the Agency's interpretation of several issues that had been addressed in OSHA Program Directive #100-84, dated January 31, 1978. As you noted, those interpretations applied to the old scaffold standard for construction, which was revised in August of 1996. We appreciate your taking the time to communicate with the Agency.
In the revised standard, the definition of the term "brace" has been changed editorially by replacing the word "tie" with "rigid connection," but the above interpretation is still true provided that a competent person approves the scaffold design. In the revised standard, the provision that scaffolds shall be capable of supporting four times the maximum intended load has been moved to §1926.451(a)(1).
As noted above in our answer to b., the revised standard redesignated the provision that scaffolds shall be capable of supporting four times the maximum intended load to §1926.451(a)(1). The provision that damaged or weakened scaffold components shall be immediately replaced or repaired was amended in the revised standard, and redesignated to §1926.451(f)(4). Revised paragraph (f)(4) addresses scaffold use and references back to the scaffold strength requirements in paragraph (a)(1). The interpretation above from 1978 is still valid under the revised standard with the approval of a competent person.
In the introductory text to §1926.451(c)(2), the revised standard requires base plates (and mud sills or other adequate firm foundation) at all times now for support scaffold poles, legs, posts, frames, and uprights.
Should you require further assistance, please do not hesitate to contact us again by writing to: OSHA Directorate of Construction, Office of Construction Standards and Compliance Assistance, Room N3621, Washington D.C., 20210.
