English
on hazardous materials if you are unfamiliar with the
risks associated with the particular substances you
are cutting or with which you are working.
￭ Inhalation of certain dusts, especially organic dusts such
as mold or pollen, can cause susceptible persons to have
an allergic or asthmatic reaction. Substantial or repeated
inhalation of dust or other airborne contaminants,
especially those with a smaller particle size, may cause
respiratory or other illnesses. This includes wood dust,
especially from hardwoods, but also from some softwoods
such as Western Red Cedar.
– Control dust (such as saw dust) and mists (such as
oil mist from chain lubrication) at the source where
possible.
– Always work with a properly sharpened saw chain,
which produces wood chips rather than fine dust.
– To the extent possible, operate the chain saw so that
the wind or operating process directs any dust, mist
or other particulate matter raised by the chain saw
away from the operator.
– When respirable dust or other particulate matter
cannot be kept at or near background levels, always
wear an approved and properly rated respirator and
follow the recommendations of governmental
authorities (e.g., OSHA/NIOSH/MSHA; for Canada:
CCOHS/PHAC/MSHA) and occupational and trade
associations.

6 IMPORTANT SAFETY INSTRUCTIONS
￭ If the vegetation being cut or the surrounding ground is
coated with a chemical substance, such as pesticide or
herbicide:
– Read and follow the instructions and warnings that
accompanied the substance coating the vegetation
or surrounding ground.
￭ Breathing asbestos dust is dangerous and can cause
severe or fatal illness, respiratory illness or cancer,
including mesothelioma. The use and disposal of
asbestos-containing products is strictly regulated by
OSHA and the EPA (for Canada: CCOHS and ECCC).
– Do not use your chain saw to cut or disturb asbestos
or asbestos-containing products.
– Stop work immediately and contact the relevant
state and local authorities and/or EPA (for Canada:
ECCC), your employer or local OSHA (for Canada:
CCOHS) representative if you have reason to
believe that you might be disturbing asbestos.
￭ Repeated contact with waste oil can cause skin cancer
and its use is harmful to the environment.
– Do not use waste oil to lubricate the bar and chain of
your STIHL chain saw.
