0.3 Thermal hazards
1
Under certain ambient conditions the TRIVAC-B-DOT may attain a
temperature of over 70 °C (158 °F). There then exists the danger of
receiving burns.
Note the symbols on the pump pointing to the hazards, and in the
case of a hot pump wear the required protective clothing. All work
on the “pump still warm from operation” should only be done using
protection gloves.
2
Before servicing and maintenance work always leave the pump to cool
down.
3
Note the warning information on the housing surface. If these warning
notices have been removed, covered or obstructed, include corre-
sponding additional warning notices.
0.4 Hazards caused by materials and substances
1
Before pumping oxygen (or other highly reactive gases) at
concentrations exceeding the concentration in the atmosphere
(> 21 % for oxygen) it will be necessary to use a special pump. Such
a pump will have to be modified and degreased, and an inert special
lubricant (like PFPE) must be used.
2
Before commissioning the TRIVAC-B-DOT, make sure that the
media which are to be pumped are compatible with each other so
as to avoid hazardous situations. All relevant safety standards and
regulations must be observed.
3
When pumping toxic, chemical, radioactive and corrosive gases
as well as pyrophorous substances, the operating company is
under the obligation to comply with the national and international
safety regula tions and guidelines. Regarding the suitability of the
TRIVAC pumps for special applications in which such gases, respec-
tively substances shall be pumped, Leybold should be consulted first.
4
If the pump has previously handled hazardous gases, implement the
proper precautionary measures before opening the intake or exhaust
connection.
Before opening the pump, purge it for a longer period of time with an
inert gas.
If necessary, use gloves, a respirator and/or protective clothing and
work under an exhaust hood. Firmly seal off the pump.
When shipping the contaminated pump for servicing, please also state
the type of hazard. For this you must use a form which we have pre-
pared for you.
5
Contaminated parts can be detrimental to health and environment.
Before beginning with any work, first find out whether any parts
are contaminated. Adhere to the relevant regulations and take the
necessary precautions when handling contaminated parts.
