2 Safety
These operating instructions contain basic instructions
which have to be observed during set-up, operation and
maintenance. For this reason, these operating instructions
must by all means be read before installation and commis-
sioning by the installation technician as well as by the com-
petent specialist staff / user, and must be permanently avail-
able at the location of the plant. Not only the general safety
instructions mentioned in this chapter on safety have to be
observe, but also the special safety instructions mentioned
in the other chapters.
2.1 Labelling of notes in the operating instructions
The safety instructions mentioned in these operating in-
structions, which may cause hazards for persons in case of
non-observation, have been marked by the general danger
symbol
(Safety signs in conformity with ISO 7000 -0434),
in case of warning against electrical voltage with
(Safety signs in conformity with IEC 417 - 5036).
In case of safety instructions, the non-observation of which
may cause hazard for the plant and its functions, the word
added is
.
Instructions attached directly to the plant, such as
- Rotation arrow (on fan cover)
Marks for fluid connections must be observed and must be
kept in legible condition.
2.2 Qualification and training of staff
The staff for operation, maintenance, inspection and installa-
tion must have the corresponding qualification for this work.
For this reason, the area of responsibility, the competency
and the supervision of the staff has to be precisely defined
by the company. If the staff does not have the necessary
knowledge, the said has to be trained and instructed. If and
when necessary, this may be carried out by the manufac-
turer / supplier by order of the purchaser of the plant. More-
over, the user has to ensure that the content of the operat-
ing instructions is understood completely by the staff.

2.3 Hazards caused by non-observation of safety
instructions
The non-observation of the safety instructions may endan-
ger persons as well as the environment, and may have con-
sequences for the plant. The non-observation of the safety
instruction will result in the loss of all claims for damages.
In detail, the non-observation may cause the following haz-
ards, for example:
•
Malfunction of important functions of the plant
•
Malfunction of the mandatory methods of maintenance
and repair
•
Danger to persons caused by electrical, mechanical and
chemical effects
•
Danger to the environment caused by leakage of dan-
gerous substances
2.4 Safety-conscious work
The safety instructions mentioned in these operating instruc-
tions, the existing national regulations on accident preven-
tion as well as potential in-company work, operating and
safety instructions of the user must be observed.
2.5 Safety instructions for user / operator
If hot or cold machine parts could lead to haz-
ards, these parts have to be protected against
touch by the user.
Touch protection for moving parts (such as cou-
pling) must not be removed from plants in opera-
tion.
Leakage (of the shaft seal, for example) of haz-
ardous material conveyed (e.g. explosive, toxic,
hot) must be removed in such a way that no dan-
ger is caused to persons and the environment.
Legal regulations have to be observed.
Hazards caused by electric energy must be
excluded (for details here, please refer to the
country-specific regulations and the regulations
of the local energy supply companies).
