0.4 Hazards Caused by Materials and Substances
1 The vacuum line must be leaktight. Hazardous process gases may
escape or the pumped gases can react with air or atmospheric humid-
ity. After installation of the pump and after servicing work on the vacu-
um system, a leak test will always be necessary.
When pumping hazardous gases we recommend a leak test on a reg-
ular basis. Leaks in the pump cannot be ruled out under all circum-
stances. When pumping hazardous gases, the operator must ensure
that leaks at the pump will not be a hazard.
2 Since not all application related hazards for vacuum systems can be
described in detail in these Operating Instructions, Leybold has availa-
ble a separate document (Safety Booklet) in which the hazards and
general safety concepts for design, operation and maintenance of vac-
uum systems are explained.
When planning to pump hazardous substances with this pump, read
the related chapters in the Safety Booklet and in these Operating
Instructions first. You can download the Safety Booklet from our
homepage.
3 Before commissioning the pump, make sure that the media which are
to be pumped are compatible with each other so as to avoid hazard-
ous situations.
4 If required additional monitoring of the purge gas quantities is neces-
sary from the side of the operator when a well-defined and ensured
dilution is necessary from the side of the process.
The type of protection depends on the specific process and needs to
be assessed by of the customer.
5 The cooling water from the return is not of drinking water quality and
should not be used for this purpose.
After having operated the pump, the cooling water lines may suffer
from microbiological contamination. Take appropriate safety precau-
tions.
6 When the pump has been used to pump hazardous gases before,
introduce appropriate safety precautions before opening the intake or
the discharge connections. Before opening the pump, purge it for a
longer period of time with an inert gas. If necessary, wear suitable per-
sonal protection equipment like gloves, breathing protection and pro-
tection clothing, for example (see Material Safety Data Sheets for the
substances in use, the chemical reactions and the by-products). Firmly
seal off the pump. When shipping the contaminated pump for servic-
ing please also indicate the type of hazard. For this see Section 5.5
Service at Leybold.
7 Leybold is not in a position to perform servicing (repairs) and waste
disposal of radioactively contaminated pumps. Both needs to be
ensured from the side of the user.
