A ready-to-read toolbox talk on where silica dust comes from, why it causes lung disease and how water, vacuums and respirators keep it out of your lungs.
Bring a saw or grinder with a water feed or vacuum shroud, or show a photo, so the crew can see the controls.
Cutting, grinding or drilling concrete, brick, block, stone and tile releases fine silica dust. The particles are small enough to reach deep into the lungs, where they cause scarring called silicosis, along with lung cancer and kidney disease.
Today we will talk about keeping that dust out of the air and out of your lungs.
A laborer cuts concrete pavers dry with a cut-off saw because the water hose is too short to reach. A cloud of dust hangs over the area all afternoon, and three other workers breathe it in. A longer hose would have kept the dust down.
