Grinding/cutting/drilling of masonry, concrete, metal and other materials can generate dust, mists and
fumes containing chemicals known to cause serious or fatal injury or illness, such as respiratory dis-
ease, cancer, birth defects or other reproductive harm. If you are unfamiliar with the risks associated
with the particular process and/or material being cut or the composition of the tool being used, review
the material safety data sheet and/or consult your employer, the material manufacturer/supplier, gov-
ernmental agencies such as OShA and NIOSh and other sources on hazardous materials and make
certain to comply with all product warnings and instructions for the safe and effective use of the mate-
rial being cut. California and some other authorities, for instance, have published lists of substances
known to cause cancer, reproductive toxicity, or other harmful effects.
Control dust, mist and fumes at the source where possible. In this regard use good work practices
and follow the recommendations of the manufacturer/supplier, OShA/NIOSh, and occupational and
trade associations. Water should be used for dust suppression when wet cutting is feasible. When
the hazards from inhalation of dust, mists and fumes cannot be eliminated through engineering con-
trols such as vacuum and/or water mist, the operator and any bystanders should always wear a respi-
rator approved by NIOSh/MShA for the material being cut.

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities con-
tain 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 and other masonry products
• Arsenic and chromium, from chemically treated lumber
For further information, consult the following sources:

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.
