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 employer, the manufac-
turers/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 rec-
ommendations of the manufacturers/suppliers, OSHA/NIOSH, and occupational and trade associations. Water should
be used for dust suppression when wet grinding/cutting/drilling is feasible. 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 crystalline 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.
