BARTON has completed a Hazard Classification Study with the assistance of a PhD-educated safety consultant who specializes in industrial hygiene exposure assessments. The results of the study confirm our garnet products’ respirable quartz (less than 10 microns)  fraction to be less than 0.1%.  The industrial hygiene exposure assessments conducted during the Hazard Classification Study confirmed non-detectable levels of respirable quartz under normal use conditions.  Normal uses of our garnet abrasives include but are not limited to: proper handling and storage, waterjet cutting, dry abrasive blasting, vapor abrasive blasting and cleanup using wet methods and/or vacuuming of residual or spilled materials. The combination of the product’s respirable quartz content and industrial hygiene study results, as reviewed by an independent PhD, provided BARTON with an effective date to accurately assign the proper labeling of our products with a comprehensive study to support such labeling.
