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 mate-

rial safety data sheets and/or consult your employer, the manufacturers/suppliers,

governmental agencies such as OSHA and NIOSH and other sources on hazard-

ous 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 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.
