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