Specialty spill control hands-in-bag atmospheric chamber. 2 hands; medium. How to use Hands-In-Bag: 1. Unfold and spread out the "Hands-In-Bag" with the open end toward you. 2. Snip one purging tube opening and insert the gas line from the gas cylinder through the purging tube. Seal the purging tube to the gas line with tape. 3. Load the "Hands-In-Bag" with whatever equipment you may need to perform the given task. If using an electrical cord, place the cord through the additional purging tube and seal the purging tube to the cord. If you use a microscope, cut a port to accommodate the optical piece. Seal with tape. Purge to eliminate room atmosphere. Use pressure regulator. 4. With "Hands-In-Bag" loaded and purged, seal the chamber using the special tape provided. Remove protective backing from tape. Turn back tape ½ inch from each end and adhere to work surface. Place the chamber opening over onehalf of the width of the tape. Fold remaining half of the tape over the top half of the "Hands-In-Bag" opening. Starting from the center, press firmly, being sure to seal the chamber completely. Tape should extend approximately 2 inches beyond sides of the chamber opening. 5. Do not over-inflate "Hands-In-Bag". If you only inflate enough to maintain a billowed shape, it is much easier to do your work. 6. Insert hands in gloves and begin work. 7.

Do not use for handling toxic materials except in a hood or other controlled systems to prevent and protect against exposure resulting from leakage. 8. When your work is completed, fold and store your "Hands-In-Bag" for future use. If your "Hands-In- Bag" is contaminated, dispose of it as required.
