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.
