OSHA Interpretation Letters for 29 CFR 1910.1200, the HazCom Standard

OSHA

Some of these interpretations are now obsolete and refer to earlier versions of the Standard (1984, 1994) which have since changed rather significantly. Please be certain to interpret these documents in their historical vs current contexts. We are making an effort to review these interpretations and help the reader determine if they still have any validity, but this is just our opinion only and should not be relied upon as legal advice.

You can browse these by sequentially by title or perform a full-text search of all the documents using the search box at the top of each page in this section.
