WARNING

Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities contains 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 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.
