Fused Amorphous Silica As a Replacement for Ground Quartz to Reduce Inhalation Exposure to Workers in Silicone Rubber Mixing Operations
OSHA Regulations are driving the rubber industry in the replacement of crystalline silica containing dusts (fillers) due to exposure concerns. New regulations imposed in 2016 emphasize stricter standards for industrial hygiene inhalation exposure of crystalline silica. The impact on companies handling crystalline silica containing fillers as an ingredient to rubber compounds will require significant dust hygiene prevention and annual medical surveillance for workers. Regulation can also extend to processing cured rubber where dusts are generated during grinding or cryogenic operations that expose workers through inhalation.
