This is an IBC filling system for organic liquids.

First the filling capacity is adjusted.

The IBC is transported to the working area

using a powered roller conveyor.

Then the IBC is appropriately earthed at the

tubular galvanised iron cage and filling is started.

On the left side the local exhaust ventilation

is insufficient due to the missing inspection glass.

On the right side the local exhaust ventilation

is sufficient using the inspection glass.

Now the filling procedure is shown in time-lapse.

If the local exhaust ventilation is working insufficiently,

vapours leak into the working area,

shown by the red arrows on the left side.

Green arrows on the right side show

that the vapours are collected adequately

using sufficient working local exhaust ventilation.

The meter display in the diagram shows the release

of the vapour that is escaping.

Variability of the vapour concentration can be caused

by airflow in the working area.

After filling the fill pipe is pulled out and dripped off

into the IBC while local exhaust ventilation is working.

The green signal demonstrates the efficiency of

a sufficient working local exhaust ventilation.

Workers' exposure is minimised due to correct handling.

The IBC is closed immediately using an appropriate tool.
