Loading Materials and Equipment

being removed from the glove box.
• Objects in contact with contaminated material must be surface
decontaminated before removal from the glove box.
• The interior surfaces should be cleaned per user’s protocol.
• Upon completion of work, the glove box should be allowed to operate
for 5 minutes undisturbed at 100% speed or 10 minutes at 50% speed
to purge and dilute airborne contaminants from the work area.

purged for 5 minutes at 100% speed or 10 minutes at 50% speed with
the inner door open, before removing sealed material.
