OSHA has approved Washington State standards amendments covering Access to Employee Exposure and Medical Records (28 CFR 1910.20), and Servicing of Single Piece and Multi-Piece Rim Wheels (29 CFR 1910.177), both of which are identical to Federal standards. A standard amendment covering the Definition and Requirements for a Nationally Recognized Testing Laboratory was determined to be at least as effective as the Federal standard and was also approved. Decision effective 3/8/90.
