1. Safety information
Health risk
The wastewater system transports wastewater that contains faeces; in turn this faeces may contain
harmful substances. Whenever working on the system, always ensure that there is no direct contact
between the wastewater and/or soiled system parts and your eyes, mouth or skin. In the event of direct
contact, clean the affected part of your body thoroughly and disinfect if necessary. It is also possible that
the atmosphere in the tank may be harmful.
Therefore before opening the cleaning aperture (or removing the pump) ensure that the respective room
is adequately ventilated or provide for (forced) ventilation during the opening process.
Noise pollution
When the pump is operated, a noise level is created that may be a nuisance depending on how the pump
is installed. If there are maximum noise level stipulations that need to be observed, appropriate mea-
sures need to be taken. The sound damping set from KESSEL may also be helpful here.
Risk of explosion
The inside of the tank is considered to be explosive within the meaning of EN 12050 because the bio-
logical digestive process may create flammable gases (hydrogen sulphide, methane gas). Therefore,
when unscrewing the pump or the cleaning aperture lid or any other parts, ensure that the room is ade-
quately ventilated or provide for (forced) ventilation during the opening process. Whilst the tank is open,
it is forbidden to smoke or carry out any other activities in the respective room that could cause the gas
to ignite (e.g. operation of electrical devices without encapsulated motors, metalworking etc.).
