Qualification of personnel
Safety
4
A qualified employee is deemed to be a person who is able to
assess the tasks assigned to him and recognise possible dangers
based on his technical training, knowledge and experience, as well
as knowledge of pertinent regulations.
Qualified personnel who open the hydraulic components of the
pump have to be able to recognise sealing surfaces so that they do
not become scratched.
Note:
A qualification of equal validity to a technical qualification can also
be gained by several years of employment in the relevant field of
work.
Electrical technician
An electrical technician is able to complete work on electrical sys‐
tems and recognise and avoid possible dangers independently
based on his technical training and experience, as well as knowl‐
edge of pertinent standards and regulations.
The electrical technician should be specifically trained for the
working environment in which he is employed and be conversant
with the relevant standards and regulations.
Make sure that the electrical technician complies with the provi‐
sions of the applicable statutory directives on accident prevention.
A qualification of equal validity to a technical qualification can also
be gained by several years of employment in the relevant field of
work.
Electrical technician with knowledge of ATEX explosion protection
The electrical technician with an additional explosion protection
qualification should be specifically trained for the work area in
which he is employed and be familiar with the relevant standards
and regulations. The electrical technician with an additional explo‐
sion protection qualification can work on electrical systems and
independently recognise and avoid possible dangers based on his
technical training and experience.
The electrical technician with an additional explosion protection
qualification is familiar with all the standards and regulations appli‐
cable to explosion protection, in particular, but not however exclu‐
sively, with all parts of EN 60079 [Electrical equipment for areas at
risk of a gas explosion].
The electrical technician with an additional explosion protection
qualification must comply with the provisions of the applicable stat‐
utory directives on accident prevention.
Recognised competent person
To carry out explosion hazard inspections the competent person
must have:
n Completed a relevant course of study or
n Have a comparable technical qualification or
n Another technical qualification combined with long-term experi‐
ence of safety technology.
Make sure that the person is familiar with the relevant body of
standards and regulations and has worked in the area for at least
one year. The person needs to have opportunities for an exchange
of experience.
Specific requirements are placed on competent persons who per‐
form tests on repaired devices/parts. They have to be recognised
by the responsible authorities (e.g. district council) in this respect.
Instructed person

In the event of an electrical accident, disconnect the mains cable
from the mains or press the emergency cut-off switch fitted on the
side of the system!
If feed chemical escapes, also depressurise the hydraulic system
around the pump as necessary. Adhere to the safety data sheet for
the feed chemical.
Prior to commissioning the system or system component, it is the
responsibility of the system operator to obtain the latest safety data
sheet for the chemicals / equipment to be used with the system
from the supplier. Based on the information provided in the data
sheets concerning health and safety, water and environmental pro‐
tection, and taking into consideration the actual operating environ‐
ment on site, it is the responsibility of the operator to create the
legal framework for the safe operation of the system or system
component, such as for example the preparation of operating
instructions (operator's duties).
Secure all these parts in their place when using the pump.
