4.1

General maintenance information

No climbing on electrical components, pipe connections or cables during maintenance work.
Risk caused by toxic and hazardous vapours, gases and substances (e. g. bacteria, viruses). If the backwater
pumping station is located in an inspection chamber, any necessary work must always be done by specialist
staff (see 2.2).
Risk of drowning in the system chamber. In the event of a flood, a system chamber can fill with water within a
very short time. If there is a risk of water entering, the inspection chamber must not be entered until there is no
danger involved.
After all maintenance work, carry out a function test on the backwater pumping station.
