9.1 Replacing the chemical storage tanks
WARNING!
Danger from hazardous substances!
Possible consequence: Fatal or very serious inju‐
ries.
Please ensure when handling hazardous sub‐
stances that you have read the latest safety data
sheets provided by the manufacture of the haz‐
ardous substance. The actions required are
described in the safety data sheet. Check the
safety data sheet regularly and replace, if neces‐
sary, as the hazard potential of a substance can be
re-evaluated at any time based on new findings.
The system operator is responsible for ensuring
that these safety data sheets are available and that
they are kept up to date, as well as for producing
an associated hazard assessment for the worksta‐
tions affected.
Labelling the chemical storage tanks
Label the connections on the unit, the metering
accessories and the chemical storage tanks in
such a way that it is impossible to mix up the
storage tanks. It is the responsibility of the system
operator to attach and maintain the labels. We can
provide labels.
