Dust and Silica Warning
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 disease, 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, governmental
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 material 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 controls such as vacuum
and/or water mist, the operator and any bystanders should always wear a respirator
approved by NIOSH/MSHA for the material being cut.
