Some dust created by power sanding, sawing, grinding, drilling, and other 

construction activities contains chemicals known to cause cancer, birth defects or 

other reproductive harm. Some examples of these chemicals are:
  •  lead from lead-based paints,
  •  crystalline silica from bricks and cement and other masonry products, and
  •  arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type 

of work. To reduce your exposure to these chemicals: work in a well ventilated 

area, and work with approved safety equipment, such as those dust masks that are 

specially designed to filter out microscopic particles.
