4.3 Check banisters
Only grasp the handgrip with the ball electrode by its handle.
Use the ball electrode to touch the banisters and other conductive objects that may protrude into the water
and check for voltage.
Danger!
Do not touch the banisters!
Leave the danger area
immediately!
Do not use a pump!
Immediately stop all work in
the danger area.
Do not touch the banisters!
The banister may not
protrude into the water or
it may not be conductive.
No voltage detected
Voltage present!
Do not touch the banisters!
Bannister currently has
ground potential and no
voltage.
Approach the water and
carry out further tests in the
water, see 4.4.
No voltage
Do not touch the banister even when there is no voltage!
Unexpected changes in the conditions (e.g. changes in level) can suddenly put objects
protruding into the water under voltage.
