1.4. Safety Precautions

1.4.1. Electrolytes
The electrolytes mentioned in section OPERATION can be used without
involving any risk for user or equipment if the safety precautions stated for
these electrolytes are followed.
Some of the electrolytes contain perchloric acid. See section OPERATION
for further information.
Tenupol-3 is designed for use with electrolytes recommended by Struers.
Other electrolytes, e.g. electrolytes containing strong bases or acids, may
harm the construction or endanger the safety of the user.
Note that many electrolytes contain alcohol or other inflammable solvents.
Make sure that all safety precautions are followed when using such
electrolytes.
It is essential that the user is fully trained in the use of Tenupol-3 as well as
the electrolytes involved.
When cleaning the instrument after use, make sure that no electrolyte is
allowed to dry and/or crystallize inside the instrument or on the polished
material.
1.4.2. Perchloric Acid
Electrolytes from Struers with the prefix A consist of approx. 11 stock
solution, to which from 15 to 90 ml perchloric acid (60%) is added. Thus, the
ready-made electrolyte will contain from 1 to 5% perchloric acid.
Electrolytes with such a low content of perchloric acid will not imply
considerable elements of risk. Before mixing, however, there will be 60%
perchloric acid present. Therefore, the following safety precautions for
perchloric acid must be observed:
