8 Glovebox or enclosure operation
8.1 Overview
This chapter covers operation of a MBRAUN glovebox or a MBRAUN enclosure.
An enclosure is a hermetically sealed space inside a housing, made of steel or alu-
minium. Though the contents of this chapter also make reference to an enclosure, the
term "glovebox" denotes both a "glovebox" and an "enclosure" below.
8.2 Safe operation
The design of the system and the controller ensure safe operation of the glovebox. How-
ever, risks are present in the following situations:
¡ In case of faults due to incorrect operation
¡ If ambient air penetrates into the box and process materials come into contact with
oxygen
¡ If toxic or environmentally harmful glovebox atmosphere escapes to outside
¡ If a higher volume of working gas permanently escapes into a closed room during a
glovebox purge
WARNING
Improper use of a glovebox
Personal injury
► Make sure that only appropriately qualified personnel can work on the system.

► Follow all safety instructions in chapter "Safety" for the specific processes taken
place.
► Always check that the connections/screw connections are made properly.
