steel tape with a
plumb-bob attached, through the thief hatch on top of the
tank.
When he opened the thief hatch (200mm in diameter) on top of the
tank,
he was overcome by H2S gas fumes and fell 6.08m to the
ground. The H2S content
of this well is 18-22%, and worker was
not wearing respiratory protective

although it was available in his truck. The worker's
body was
discovered lying on the ground at the base of the ladder by a
local
farmer when he went to investigate why the truck was
still at the well site
with the lights
on.
