The National Institute for Occupational Safety and Health (NIOSH) is offering a free webinar for stone countertop fabrication employers 

Free Webinar: Preventing Exposure to Silica DustIf your company is cutting, grinding, sanding, or installing stone products, you need to know about the dangers of silica dust and how to protect your employees from severe and fatal lung disease.

Crystalline silica is found in granite, artificial/engineered stone, and other stone products. When workers cut, grind, drill, or polish these materials, very small particles of silica dust get in the air. Breathing in these very small (“respirable”) crystalline silica particles can cause irreversible scarring in the lungs, trouble breathing, permanent disability, and death. Silica dust can also cause lung cancer, kidney damage, and autoimmune disease.

The formal description of this event is “Working safely with natural and engineered stone products: Controlling worker exposure to silica dust during countertop manufacturing, finishing, and installation.” 

Event Information: This webinar will describe the dangers of silica exposure, employer requirements to comply with OSHA’s Respirable Crystalline Silica Rule, and methods employers can use to protect workers.
