Jack English, Acting Assistant CommissionerThe federal §1910.28 standard for scaffolding applies to suspended work with boatswain's chairs. If the work in question is performed by boatswain's chairs as used in this standard, then the tiebacks must be 90 degrees to the face of the building as specified in §1910.28(j). However, the April 10, 1990, proposed revisions to the Walking and Working Surfaces standards (55 Federal Register (FR) 13360) would allow tiebacks on boatswain's chairs to be "approximately" perpendicular to the structure face, as stated in the proposed paragraph §1910.30(g)(2) (55 FR 13406). Where an employer is in compliance with the provisions of a proposed standard, it is OSHA's general policy to treat the violation of an existing requirement as a de minimis violation. A de minimis violation does not result in a citation, or penalty and need not be abated. OSHA is unable to determine a specific angle that would be unsafe, because a safe tieback angle would depend on several factors, such as the distance from the parapet or roof edge to the anchor point. In determining whether a tieback was attached at a safe angle, OSHA would use appropriate outside references and the information gathered at the site.
