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. 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 cutting 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 materials being used.
Grinding/cutting/drilling of masonry, concrete, metal 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 cutting such materials, always follow the respiratory
precautions mentioned above.
