||Final Rule on Lift Slab Construction Operations, Concrete and Masonry Construction Safety Standards.
This rule revises OSHA''s Safety Standards for Lift Slab Construction Operations. This rulemaking updates specific requirements for lift-slab construction operations that were incorporated by reference in the existing ANSI standard (A10.9-1970), and adds new requirements to provide additional protection for workers engaged in lift-slab construction operations. This revision eliminates ambiguities caused by incorporating the ANSI standard by reference and strengthens the lift-slab requirements by eliminating weaknesses or gaps in coverage that existed through the reference to the outdated ANSI standard. Effective Date: 12/17/90. CONTACT: James Foster (202)523-8151.
