We have been expecting it since 2005. It's here, and it's big. The OSHA final rule regarding 29 CFR 1910.269 and 1926 Subpart V was announced April 1, popularly known as April Fools’ Day. The significance couldn't have been missed by those at the U.S. Department of Labor. Who says they have no sense of humor? The unofficial PDF version published April 1 has 1,607 pages. The official version – published April 11 in the conventional three-column Federal Register format – has a mere 429 pages. The final rule becomes effective July 10.
