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 place.

Why is Silica Hazardous? Silica Safe

The dust created by cutting, grinding, drilling or otherwise disturbing these materials can contain crystalline silica particles. These dust particles are very small. You cannot see them. This respirable silica dust causes lung disease and lung cancer. It only takes a very small amount of airborne silica dust to create a health hazard.
