DESCRIPTION:

attempting to thaw the meter

upstream valve was not closed when the worker
disconnected the
meter line from the valve manifold. Methanol was then
poured
into this line and fed down to the orifice where the
thawing process took
place. When the restriction was removed in
the orifice, the gas flowed up the
upstream meter line through
the valve manifold and out the disconnected fitting
to the
atmosphere at a rate of 170 P.S.I.G., asphyxiating the
worker.
