Guideline for Regeneration of Gloveboxes

Compressed hydrogen gas and certain mixtures are classified as flammable and have special handling and storage requirements.

STORAGE

- Store in approved vented gas cylinder cabinet with safety cap in place when not in use.

- Cylinders must be secured with nylon strap or chain

- Do not store with incompatible chemicals or gases

HANDLING

- Ensure all equipment are electrically grounded and bonded

- Excess flow restriction device must be installed at the cylinder

- Flammable gas detection must be use

- When changing cylinders, use a leak solution to check for leaks

GLOVESBOXES

Regeneration of the copper catalyst and molecular sieve requires the use of a gas mixtures of hydrogen and nitrogen. Mixtures greater than 5.5% hydrogen in nitrogen is classified as flammable gas and should be avoided if possible.

AIRGAS - 0.1-5.5% HYDROGEN / NITROGEN 94.5-99.9%
