0.5 Danger of ignition
1
The standard version of the TRIVAC-B-DOT is
not
suited for operation
in explosion hazard areas.
2
The TRIVAC pumps including the accessories are fundamentally
not
suited for pumping of combustible and explosive gases or vapours.
Mixtures of substances may, regarding the fire and explosion risk be
critical or uncritical. The operating company is under the commitment
to analyse this and rate the hazard potential accordingly so as to
therefrom derive the necessary safety measures which must be intro-
duced.
3
Provided ignitable or pyrophorous substances are present in the
equipment you must:
n
ensure that no air can enter into the equipment,
n
ensure that the system is leak-tight,
n
with an inert gas purge (with nitrogen, for example) dilute all igni-
table gases or vapours which may enter into the pump through the
pump’s inlet and/or with an inert gas purge reduce the concentration
of ignitable gases or vapours in the pump and in the exhaust line to
less than a quarter of the lower explosion limit (LEL) published for the
respective gases.
0.6 Hazard caused by noise
1
The noise level produced by the pump less than 60 dB(A). Suitable
hearing protection measures must be introduced.
