ACCIDENT DESCRIPTION:
The worker

the
workers returned to the work area to continue with the
cleaning process. The
deceased entered the vessel from
underneath the west end and emerged again
moments later. He
went to the east end of the vessel and climbed the scaffold
to
enter the vessel by the manway. The vessel was divided and there
was a
small compartment in the east end which, apparently, had
not been cleaned.
A worker saw him climb the scaffold, but did
not see him enter the vessel. The
worker apparently entered
into the vessel before the worker assigned to be
safety guard
had returned from his lunch break. After some time, he was
missed
by the crew. He was discovered lying in the east end
compartment of the
vessel, in a pool of sludge. The rescue and
subsequent resuscitation attempt
was
