trained and instructed accordingly. If necessary, the operator may require the
manufacturer/supplier to provide such training. Furthermore the operator must
make sure that the personnel fully understand the contents of the operation
manual.
2.3 Dangers of ignoring the safety symbols
Ignoring the safety directions and symbols may pose a danger to humans as
well as to the environment and the machine itself. Non-observance may void
any warranties.
Non-observance of safety directions and symbols may, for example, entail the
following:
– Failure of important functions of the machine/plant
– Failure of prescribed methods for maintenance and repair
– Danger to persons due to electrical, mechanical and chemical influences
– Danger to the environment because of leakage of hazardous materials
– Damage to equipment and buildings
2.4 safety-oriented operation
The safety directions contained in the operation manual, existing national regu-
lations for the prevention of accidents as well as internal working, operational
and safety regulations of the operator must be observed at all times.
2.5 safety directions for the operator/user
If hot or cold machine parts pose a danger, such parts must be protected by the
operator/user against contact.
Protective covers for moving parts (e.g. coupling) must not be removed when
the machine is running.
Leakages (e.g. at the shaft seal) of hazardous pumping media (e.g. explosive,
toxic, hot liquids) must be disposed of in such a way that any danger for per-
sonnel and the environment is removed. All government regulations must be
observed at all times.
Any danger caused by electrical energy must be excluded. For details see for
example the VDE regulations and the local utilities.
2.6 safety directions for maintenance, inspection and assembly work
It is the user’s responsibility to make sure that all maintenance, inspection and
assembly work is performed exclusively by authorized and qualified experts
sufficiently informed through careful perusal of the operation manual.
The accident prevention regulations must be observed.
Basically, all work on the machine is to be performed while the machine is not
in operation. The sequence for shutting the machine down described in the
operation manual must be strictly observed.
