1.4 Compliance with regulations
relating to safety at work
When operating the pump the safety instructions
contained in this manual, the relevant national
accident prevention regulations and any other
service and safety instructions issued by plant
management must be observed.
1.5 Safety instructions relating to
operation
•
If high or low temperature pump/pump set
components involve hazards, steps must be
taken to avoid accidental contact.
•
Guards for moving parts (e.g. couplings) must
not be removed from the pump/pump set while
in operation.
•
Any leakage of hazardous (e.g. explosive,
toxic, hot) fluids (e.g. from the shaft seal) must
be drained safely so as to prevent any risk to
persons or the environment. Statutory
regulations are to be complied with.
•
Hazards from electricity are to be avoided by
the user (see for example the VDE-
specifications and the bye-laws of the local
power supply utilities).
1.6 Safety instructions relevant for
maintenance, inspection and
assembly work
It is the plant manegement’s responsibility to
ensure that all maintenance, inspection and
assembly work is performed by authorized
personnel who have adequately familiarised
themselves with the subject matter by studying
this manual in detail.
Any work on the machine must only be performed
when it is at a standstill. It is imperative that the
procedure for shutting down the machine
described in this manual is followed.
Pumps and pump sets, which convey hazardous
media, must be decontaminated.
On completion of the work all safety and
protective guards must be re-installed and made
operative again. Prior to re-starting the machine,
the instructions listed under “first commissioning”
are to be observed.
1.7 Safety instructions for the use in
areas with explosion hazard
In this section information is given for operation in
areas where an explosion hazard exists.
1.7.1 Complete pump sets
If the pump is combined with other mechanical or
electrical components in one set, the category of
the complete unit will correspond, based upon the
Directive 94/9/EC, only to that category with which
all of its components comply.
Note:
These comments are of particular importance
when pumps, which conform to a given category
of Directive 94/9/EC, are powered by a driver
which is not in the same category.
Although the pump may bear the Ex sign, the set
should not be used in areas with an explosion
hazard when the motor is not classified for this
application.
This means that plant management personnel
should always check that all elements of the set
comply with the Directive 94/9/EC.
1.7.2 Execution of coupling guards
Coupling guards that are to be used in areas with
an explosion hazard, have to fulfil one of the
following criteria:
•
consist of non-sparking material, e.g. brass.
•
if they consist of sparking material, e.g. steel
sheet, they must be designed in such a way
that the rotating parts will not come in contact
with any part of the guard if errors, that could
be foreseen, are committed by the user, e.g if
a person steps on the guard.
