CORRECTIVE ACTION
WARNING
Carbon monoxide is a colorless, odorless, deadly poison
which, when breathed, deprives the body of oxygen and
causes suffocation. Exposure to air containing carbon
monoxide produces symptoms of headache, dizziness, loss of
muscular control, apparent drowsiness, and coma. Permanent
brain damage or death to personnel may result from severe
exposure. Carbon monoxide occurs in exhaust fumes of
internal combustion engines.
Carbon monoxide may become dangerously concentrated
under conditions of inadequate ventilation. Refer to page a
of Warning Summary for further precautions that must be
observed to ensure safety of personnel.
1. Check exhaust manifold, pipes, flex tubes, muffler and stack for leaks
and rusted through areas with engine running. If any leaks are found,
notify supervisor that rusted leaking parts require replacement.
2. Check exhaust system clamps for leakage with engine running. If any
leaks are found, notify supervisor that clamps require tightening or
replacement.
