WARNING
Some dust created by power sanding, sawing,
grinding, drilling, and other construction activi-
ties 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, cement,
and other masonry products.
• Arsenic and chromium from chemically
treated lumber.
Your risk from these exposures varies, depend-
ing 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.
