,_ WARNING I
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, 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
dust masks that are specially designed to filter out microscopic particles.
