8. Operation
8.1 Safety instructions for the operation of Polydos
systems
The system must only be operated by authorised and
qualified persons.
Wipe up spilled water, polymer or polymer solution
immediately to avoid slipping hazard.
Make sure that you have a secure foothold when filling the
dry-material feeder. For safety reasons Grundfos strongly
recommends the installation of an automatic powder
conveying system.
Do not step on the system. The system is not designed to
carry the weight of a person.
WARNING
Chemical hazard
Death or serious personal injury
‐
Wear personal protective equipment.
‐
Observe the chemical manufacturer's safety data
sheets (SDS) and safety instructions of the used
chemicals. The required actions are described in the
safety data sheet. Check the safety data sheet
regularly and replace, if necessary, as the hazard
potential of a substance can be re-evaluated at any
time based on new findings. The operating company is
responsible for ensuring that the safety data sheets are
available and that they are kept up to date, as well as
for producing an associated hazard assessment for the
workstations affected.
