2 SAFETY CONDITIONS
Gardner Denver Deutschland GmbH accepts no
responsibility for material damage or injuries that
arise from non-observation of safety conditions or
the failure to observe normal levels of care and at-
tention, even where this is not expressly stated in
these operating instructions.
The operating instructions for the compressor
must be observed in addition to these operating in-
structions.
2.1 Identification of safety
instructions
Within the operating instructions, safety instruc-
tions are used as special warnings with the follow-
ing described names and symbols.
These special warnings are intended to prevent
danger and are located close to the possible dan-
ger both in terms of space and time:
on the system close to the danger source
in the operating instructions, before a sequence
of actions / activity is described
Structure of safety instructions
The special warnings in the operating instructions
are structured as follows:
DANGER WORD
Safety sign
Danger (danger sequence)
Description of the danger (danger
source)
Protective measure (danger pre-
vention)

quence names the type of hazard.
Description of the danger (danger source): The
danger source names the cause of the hazard.
Protective measure (danger prevention): Dan-
ger prevention describes the measures for com-
batting the hazard.
Danger word: The danger word subdivides the
severity of the danger into four steps, graphically
highlighted by different colours. The danger word
is used in the safety instructions as described be-
low.
DANGER indicates a directly dangerous situa-
tion which, if not protected against, could result in
death or serious (irreversible) injuries.
WARNING indicates a potentially dangerous situa-
tion which, if not protected against, could result in
