GENERAL WARNINGS
CALIFORNIA PROPOSITION 65
Engine exhaust and some of its constituents,
and some dust created by power sanding,
sawing, grinding, drilling and other construction
activities contains chemicals known to the Sate
of California to cause cancer, birth defects and
other reproductive harm. Some examples of
these chemicals are:
Lead from lead-based paints.
Crystalline silica from bricks.
Arsenic and chromium from chemically treated
lumbar.
Your risk from these exposures caries, depend-
ing on how often you do this type of work. To
reduce your exposure to these chemicals:
ALWAYS work in a well ventilated area, and
work with improved safety equipment, such
as dust masks that are specifically designed to
filter out microscopic particles.
SILICOSIS WARNING
Grinding/cutting/drilling of masonry, concrete,-
metal and other materials with silica in their
composition may give off dust or mist contain-
ing crystalline silica.
Silica is a basic components of sand, quarts,
brick clay, granite and numerous other minerals
and rocks. Repeated and/or substantial inha-
lation of airborne crystalline silica can cause
serious or fatal respirator disease, including sil-
icosis. In addition, California and some author-
ities have listed repairable crystalline silica as a
substance known to cause cancer. When cutting
such materials, always follow the respiratory
precautions mentioned above.
RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete,metal and fumes containing
chemicals known to cause serious or fatal injury or illness, such as respirato-
ry disease, cancer, birth defects or other reproduction harm, if you are
unfamiliar with th risks associated with the particular process and/or materi-
al being cut or the composition of the tool being used, review the material
safety data sher 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, repro-
ductive 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 manufactures of 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, mist and fumes cannot be eliminated, the operator and any bystand-
ers should always wear a respirator approved by NIOSH/MSHA for the materials being used.
