OSHA  issued an interpretation for Standard 1910.1200(d); 1910.1200 , Classification of Combustible Dusts, on December 27, 2013.

The interpretation is to be used by compliance safety and health officers (CSHOs) in determining  “whether manufacturers or importers have properly classified their products for combustible dust hazards under the revised Hazard Communication Standard (HCS).”


This guidance shall be used when inspecting manufacturers and importers, usually from referrals concerning inadequate or inappropriate labels or SDSs are conducted, not inspections of downstream users. Until OSHA addresses these issues through rule making, CSHOs shall use this document to determine if manufacturers and importers (from now on “classifier”) are in compliance with the obligations of 1910.1200(d) for combustible dust. CSHOs may direct any questions that arise in applying this guidance to the Directorate of Enforcement Programs or the Salt Lake Technical Center (SLTC).
