SECTION 1
SAFETY
Federal Regulations
SILICOSIS WARNING
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 miner-
als and rocks. Repeated and/or substantial inhalation of air-
borne 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 materi-
als, always follow the respiratory precautions mentioned
above.
RESPIRATORY HAZARDS
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 associ-
ated 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 pub-
lished lists of substances known to cause cancer, reproduc-
tive 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 recom-
mendations of the manufacturers or 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.
