[Circumstances of Incident]
The accident occurred at a plant that
manufactures
steel framing for construction.
The plant carries out work that involves
drilling holes, cutting and welding
of steel
pillars and girders used in construction.
These prefabricated steel frames are
then
delivered to construction sites.
Since the start of his working shift
on the
day of the accident, the victim had
been
carrying out work using an overhead
traveling
crane to load finished steel frames
onto
the cargo bed of a large-size truck.
At around 13:40, another worker who
was engaged
in welding work nearby looked over
and noticed
that the victim who had been handling
the
loading work had fallen down on his
right
side and a steel frame was lying atop
him.
At the time, it was noticed that the
sling
rope being used by the victim had only
one
eye attached to the loading hook of
the overhead
traveling crane.

[Causes]
The following can be cited as the causes
of this accident.
1 The direct cause was that an inappropriate
method was used to unhook the sling
rope
from the overhead traveling crane while
loading
fabricated steel frames onto the truck.
In other words, the method of lifting
a load
by the overhead traveling crane while
only
one eye of the sling is attached to
the hook
is inappropriate and should be avoided.
2 The two following factors can be
cited
as indirect causes.
[1] There was no facility that allowed
the
worker to safely move up and down between
the floor and the truck bed or the
top of
the load on the truck bed.
[2] There was no operation leader.
