[Circumstances of Incident]
This accident occurred during tree
felling
work in a mountain.
Operations at this site were to be
started
to cut downJapanese cypress and cedar
trees
and transport the felled timbers by
means of a logging line, which had
been installed
two days before the accident.
In the morning of the day, nine
workers
carried out test operations of
the
logging line and cut down a small
number
of trees. In the afternoon, full operations
of the line were to be carried
out to
pick up and transport felled timbers.
Operations in the morning have been completed
smoothly. While all workers have
been engaged
in their assigned jobs in the afternoon,
a worker's voice was heard calling
for help
from his working site higher up the
mountain.
The site supervisor and two colleagues
hurried
to the site and found the
worker
sitting on the ground with his left
thigh
bleeding. The worker was immediately
hospitalized
but died due to excessive bleeding.

[Causes]
While the details of this accident
are not
fully known, as the worker was working
alone,
the following can be cited as the major causes
of this accident.
1 The site where the victim was working
was a
steep slope where a large number
of
trees were growing. As the worker
was
trimming branches with a chain
saw,
it is assumed that he cut his left
thigh
by the chain saw when he slipped
and
fell or was caught by branches.
