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-based paints, crystalline silica from bricks
and cement or other masonry products, arsenic and chromium from chemical
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.
