SPECIFICATIONS

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.
