FGD gypsum safety data sheet guidance document

Haley & Aldrich (Maryann Sanders. Laura Fell)

This document and its appendices are aimed at aiding ACAA member companies and the coal ash beneficial use community in the development of Safety Data Sheets (SDSs) for flue gas desulfurization (FGD) gypsum. A companion document addresses SDS development for other Coal Combustion Products (CCPs), including fly ash, bottom ash, circulating fluidized bed (CFB) fly ash, and CFB bed ash. OSHA has updated its hazard communication requirements to be consistent with the United Nations Globally Harmonized System, with the ultimate goal of accurately and consistently representing the hazards associated with product uses. OSHA now requires that companies prepare and have available SDS for their products, including gypsum – these replace the Material Safety data Sheets (MSDS) that were in use until June 2015.
