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 sheets and/or consult your em-
ployer, the manufacturers/suppliers, governmental agencies such as OSHA
and NIOSH and other sources on hazardous materials. 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 manufacturers/
suppliers, OSHA/NIOSH, and occupational and trade associations. Water
should be used for dust suppression when wet grinding/cutting/drilling is fea-
sible. When the hazards from inhalation of dust, mists and fumes cannot be
eliminated, the operator and any bystanders should always wear a respirator
approved by NIOSH/MSHA for the material being used.
Grinding/cutting/drilling of masonry, concrete and other materials with silica in
their composition may give off dust or mists containing crystalline silica. Silica
is a basic component of sand, quartz, brick clay, granite and numerous other
minerals and rocks. Repeated and/or substantial inhalation of airborne crystal-
line silica can cause serious or fatal respiratory diseases, including silicosis. In
addition, California and some other authorities have listed respirable crystalline
silica as a substance known to cause cancer. When grinding/cutting/drilling
such materials, always follow the respiratory precautions mentioned above.
