WARNING

WEAR RESPIRAT ORY PROTECTION

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-base paints,

• Crystalline Silica from bricks, 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.
