Diacetyl, Hazard Communications Guidance Document 1


Diacetyl, Hazard Communications Guidance Document 1 :

Diacetyl (also called butanedione or 2,3-butanedione, molecular formula C4H6O2) is a natural byproduct of fermentation and is also synthesized by chemical manufacturers. Diacetyl gives butter and certain food flavorings a distinctive buttery flavor and aroma. Food flavorings containing diacetyl are used in microwave popcorn and other snack foods, pet foods, candies, baked goods, and other food products. Significant new information regarding the health effects of diacetyl and food flavorings containing diacetyl (FFCD) affects the information that must be conveyed to employers and employees under the Occupational Safety and Health Administration's (OSHA) Hazard Communication standard (HCS)(29 CFR 1910.1200). A review of existing hazard information on this chemical reveals that current material safety data sheets (MSDS) and labels do not routinely include newer health effects information. Updating MSDSs and labels will provide employers and employees with the information they need to understand the hazards associated with diacetyl and FFCD as well as appropriate protective measures to be taken. Dissemination of this newly updated information is needed to reduce exposures to these chemicals, which have been associated with respiratory illness and injury. This document provides hazard communication guidance for those manufacturers, importers, and employers who manufacture, import, or use diacetyl and FFCD. Guidance is provided for conducting appropriate hazard determinations, instituting control measures, updating labeling information, and training. This document provides guidance for using new information in hazard determinations and identifies potential short-comings with existing information in MSDSs. The HCS must be consulted for additional details regarding the standard's requirements. See more from topic source: https://www.osha.gov/html/a-z-index.html
