OSHA 1910.6 Incorporation by Reference Document List

OSHA is much more than just the couple thousand pages of the 1910, 1915 and 1926 codes. In section 1910.6 OSHA "Incorporates by Reference" over two hundred other documents.

Without pulling out the appropriate referred documents, just reading the OSHA 1910.179 is just the tip of the iceberg of overhead crane regulations.

The Unauthorized and Annotated Guide to OSHA 1910.179 Overhead and Gantry Cranes

OSHA 1910.179 is a typical document written by lawyers about an engineering topic. In this annotated version, I've attempted to use my 35+ years to decipher the meaning behind the words.

State OSHA Plans Not Part of the Federal Plan

It's not like the Byzantine nature of the OSHA spec with "Incorporation by Reference" is not confusing enough, the writers of OSHA allowed the states to administer their own programs and write their own plans. The only requirement was that the state plans had to be equal or greater (more stringent) than the federal program. As a result, we have almost half of the states with their own programs. These programs are anywhere from a simple adoption of the federal plan to a totally rewritten plan. Attached is a list of the states, the extent of difference from the federal program and contact information. 

OSHA 1910.179 is less than 7000 words, but that's just the tip of the Overhead Crane regulatory iceberg.

All these sub-documents, many of which you've probably never heard of, have the full force of law of the OSHA regulations.
