• Small gasoline engines produce high concentrations of car-
bon monoxide (CO) example: a 5 HP 4 cycle engine opera tion in an enclosed 100,000 cu. ft. area with only one change
of air per hour is capable of providing deadly concentrations
of CO in less than fteen minutes. Five changes of air in the
same area will produce noxious fumes in less than 30 min utes. Gasoline or propane powered equipment should not be
used in enclosed or partially enclosed areas. Symptoms of
CO poisoning include, headache, nausea, weakness, dizzi ness, visual problems and loss of consciousness. If symp toms occur - get into fresh air and seek medical attention
immediately.

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
manufacturers/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 eects.
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 composi-
tion may give o 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.
