WARNING! Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities, contain chemicals known (to the State of California) 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 or other masonry products,
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. (California
Health & Safety Code § 25249.5, et seq.)
