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 ce-
ment 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.)
