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 lifting
station is located in an inspection chamber, any necessary work must always be done by specialist staff (see
2.2).

2.4.2 Health risks

The 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.

2.4.3 Risk caused by noise

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

2.4.4 Explosion hazard

In accordance with DIN EN 12050-1: 2015-05 the inside of the system tank in a sewage lifting station can be
classified as a potentially explosive area. The operator of the system is responsible for this classification within
the scope of a risk assessment. A classification of zones is only required if potentially
– explosive gases occur simultaneously, e.g. through the introduction or formation
– of sewer gas, and measures to prevent a hazardous concentration of hazardous gases such as
aeration and ventilation prove inadequate.
The formation of a hazardous, potentially explosive atmosphere can be avoided during normal operation with
a standard-compliant installation and operation in accordance with EN 12056-4 and sufficient exchange of the
atmosphere in the system tank.
Notwithstanding this, the operator of the system must guarantee adequate occupational safety during all work
on the system. Special risks arise through toxic gases such as hydrogen sulphide as well as a lack of oxygen.
This is why appropriate safety measures such as measuring safe levels or forced ventilation in accordance with
occupational safety regulations have to be carried out.

2.4.5 Risk caused by heat

Risk of burning by touching hot surfaces. When in operation for longer periods, wastewater pumps develop a
high temperature on the housing surface. Wear protective equipment (gloves) or allow the pumps to cool down
accordingly.

2.4.6 Risk caused by unexpected wastewater pump start-up

The wastewater pump can start up at any time if the lifting station is not disconnected from the power supply.
Always have specialist staff remove the wastewater pump and only after the system has been cleared and
secured against being switched on again unintentionally.
