0.3 Thermal hazards
1
Under certain ambient conditions the TRIVAC B may attain a tempera-
ture 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 pro-
tection 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
The vacuum line and the exhaust line must be leaktight. Hazardous
process gases may escape or the pumped gases can react with air or
atmospheric humidity. After installation of the pump and after servicing
work on the vacuum system, a leak search will always be necessary.
When pumping hazardous gases we recommend a leak search on a
regular basis. Leaks in the pump cannot be ruled out under all circum-
stances. When pumping hazardous gases, the operator must ensure
that 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
vacuum 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
The pump is not suited for oxygen operation.
4
Before commissioning the TRIVAC B, 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.
5
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 regulati-
ons and guidelines. Regarding the suitability of the TRIVAC B pumps
for special applications in which such gases, respectively substances
shall be pumped, Leybold should be consulted first.
6
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.
