How to Prevent Silica Dust when Drilling or Grinding
If no dust extraction is available for drilling or grinding, running a water hose onto the surface or holding a vacuum up to the tool will keep dust down Use a drill dust attachment by turning the vacuum on and sticking the attachment to the surface The suction from the vacuum should hold it in placeAug 26, 2020 Crystalline quartz, the most common form of silica, is a component of sand, stone, rock, concrete, brick, block, and mortar One of the oldest known workplace hazards is silica dust inhalation Chipping, cutting, drilling, and grinding materials that contain crystalline silica releases respirable crystalline silica particles into the airWhat is the OSHA Silica Dust Permissible Exposure Limit Fine grinding produces a surface with little deformation that can easily be removed during polishing Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 90 and 60 µmMetallographic grinding and polishing insight Struers
