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 decontaminated pump for ser-
vicing please also indicate the type of hazard. For this see Section 5.1
Service at Leybold.

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.
9
When disposing of the pump, used lubricants and used oil filters
observe the applicable environment regulations.
10
When pumping hazardous gases you must assume the presence of
hazardous residues in the pump.
11
If the pump has been contaminated by the process or through envi-
ronmental influences, it must be decontaminated professionally.
Contaminated parts can be detrimental to health and the environment.
Before beginning with any repair and maintenance work inform yourself
about any possible contamination. When handling contaminated parts
observe the pertinent regulations and comply with the necessary pro-
tection measures.
When shipping contaminated pumps which require approval by the
authorities, note the applicable regulations regarding packaging and
shipping.

Some pumps use perfluoropolyether
(PFPE)
as lubricant.
When handling PFPE you should observe the following:
During thermal decomposition at temperatures over 290 °C toxic and
corrosive gases are released. When handling PFPE keep it away from
open fires. Do not smoke with PFPE on your fingers.
Touch the inner sections of the pumps only while wearing clean gloves,
and use clean tools;
do the necessary work in clean and dry rooms;
after having removed the pump from its packaging, start it up as
quickly as possible;
as cleaning agents solvents based on hydrofluorether compounds may
be used.
13
Fluoropolymers are used as sealants (FKM) and as lubricants (PFPE) in
the pumps. In case the pump suffers a severe mechanical failure, the
possibility of hazardous substances being released owing to their ther-
mal decomposition cannot be excluded. The hazards caused by such
decomposition are described in the Material Safety Data Sheets for the
materials, for example.
