Risks caused by the product

2.4.1 Risk caused by special location / ambient conditions

Risk caused by toxic and hazardous vapours, gases and substances (e. g. bacteria, viruses). If the backwater
lifting station is located in an inspection chamber, any necessary work must always be done by specialist
staf2.2see 2.2).

2.4.2 Risk of electric shock when plug has been screwed off

There is a risk of electric shock at the control unit (230V model type only) if one of the plugs for power supply
to the pumps has been dismantled. The union nut on the electric plug must be fitted so tightly that it cannot
be loosened without a tool (e.g. by children) (see 3.8).

2.4.3 Risk caused by hazardous atmosphere

There is a risk of a hazardous atmosphere occurring in the chamber system during work. Make sure the
system is well aerated and use safety equipment such as e.g. a multi-gas warning device if appropriate.

2.4.4 Health risks

The backwater lifting station pumps wastewater with sewage which can contain hazardous substances. Make
sure eyes, mouth or skin do not come into direct contact with the wastewater or parts of the system soiled
by it. In the case of direct contact, the part of the body affected must be washed thoroughly immediately and
disinfected if necessary. Wear personal protective equipment.

2.4.5 Risk caused by noise

Operation of the backwater lifting station can cause a high noise level. Wear appropriate protective equipment
if necessary and take sound-insulating measures.

2.4.6 Explosion hazard

The currently valid Ordinance on Industrial Safety and Health and the Ordinance on Hazardous Substances
must be observed. A risk assessment must evaluate potential hazards for normal operation and all work on
the system itself. This can result in special measures having to be applied, such as the sufficient exchange of
air.
If the wastewater tank is open, make sure there are no sources of ignition in the direct vicinity (e.g. operation
of electrical devices without encapsulated motor, metal working, smoking etc.).
