FIGURE 7. When the conveyor is running, the dust bags inflate,
and a stoppage releases the dust back to the belt
sealed, that tape had to come off.
The maintenance supervisor commented
that he'd never had to do
that, which was an indication that
trouble might lie ahead.
The access door provided a good
view of the material flow, but the
opening allowed huge volumes of
dust to billow out, forcing the technicians
to quickly re-close the opening.
In doing so, they were reminded
why duct tape should never be used
to seal an inspection door. When it
was closed, the door latched properly,
but a small gap remained
around the edges, which undoubtedly
prompted the use of the tape
seal in the first place. The air that
was now being forced out from that
gap travelled at high speed, and carried
with it a cloud of airborne dust
particles. Unfortunately, the tape that
had been removed was no longer
sticky and could not be used to reseal
the gap. So the technicians were
faced with a dense stream of black,
flammable coal dust that essentially
sand-blasted the team. It took only
a few minutes for the supervisor to
run downstairs and grab a new roll of
