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
• 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.
