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

Your risk of exposure to these chemicals 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 lter out microscopic
particles.
