When grinding concrete, do you have a dust shroud on your grinder? If so, do you also have a high-efficiency particulate air (HEPA) vacuum or just a regular shop vacuum? When grinding, do you work in a fog of silica dust? (Photo 1). Not only are you exposing yourself, you are exposing the occupants of the home or business to silica dust as well.
Crystalline silica is a common mineral found in the earth’s crust. Materials like sand, stone, concrete, and mortar contain crystalline silica. It is also used to make products such as glass, pottery, ceramics, bricks and artificial stone.
