Transferring Materials to the Outside

All open chemical weigh vessels or containers must be sealed before
removing materials from the glove box main chamber.

Objects in contact with previously contaminated internal atmospheres
must be surface decontaminated or bagged before removal from the
glove box through the transfer chamber.

After placing materials to be removed in the transfer chamber and
locking the internal door, the transfer chamber must be evacuated and
filled approximately 1-5 times depending on vacuum level achieved.
This ensures the removal of any remaining airborne contaminants
before the outer door is opened. Never apply a high vacuum purge
below 2" mercury pressure on sensitive electronic moisture and
oxygen monitors. The exact number of cycles should be determined
by your Safety Officer.
Shutdown

To help preserve the controlled atmosphere, leave the glove box main
chamber under -1" to +1" water gauge pressure and continuously run
the Gas Purifier blower. The use of the accessory external glove port
covers can assist in preserving the inert atmosphere by reducing
permeation through the gloves.

Keep the outer door closed when not in use.
Hazardous Use with Chemicals
Hazardous chemicals may be used safely only when the glove box
vacuum pump is properly vented and/or filtered to the outside. Consult
your Safety Officer for proper venting and filtering of the vacuum pump
exhaust.
Prohibited Materials Use
Due to stainless steel components, the Gas Purifier and glove box interior
must not be exposed to mineral acid. The Gas Purifier and glove box life
spans will be limited with use of mineral acids. Additionally, materials
referenced in Chapter 3 cannot be used (such as alcohols, halides, halogens,
hydrazine, heavy metals, mercury, arsine, phosphene, and sulfur containing
compounds) because they will poison the Gas Purifier catalysts and reduce
their effectivity and lifespan.
NOTE: Should the catalysts inside the Gas Purifier become ineffective
after two regeneration cycles, the two catalysts can be replaced. See
Chapter 6: Maintenance and Appendix A: Replacement Parts for
replacement.
