Carry out the following steps to troubleshoot oxygen in the workspace chamber.
1. Make sure the arm port doors and sleeve assemblies are correctly installed.
2. Verify proper sleeve donning, and arm port entry and exit procedures have been used.
3. Check if closed containers are being introduced through the pass box. Closed containers
can hold significant volumes of oxygen.
a. Containers should be loose-capped when placed in the pass box.
4. Verify that the manometer is filled with water. The water level should be at the bottom of the
two reference rings if the chamber is under the normal operating overpressure of 0.5
inches (1cm).
5. Verify that gas supply lines are attached to both the BACTRON GAS IN 1 and GAS IN 2
ports
6. Make sure the foot pedal controls branched supply line is securely connected to the barb
adaptors on both arm ports.
7. Check that the foot pedal assembly GAS and VAC lines are connected to the GAS OUT
and VAC OUT ports on the BACTRON.
8. Make sure that both box doors are being closed after all transfers.
9. Set the AMG cylinder regulator to 20 psi to ensure adequate pressure. Check for kinks or
damage to AMG gas supply line.
10. Consolidate pass box uses if possible to reduce the number of daily chamber entries.
11. Uninstall the catalyst cartridge. If the cartridge is not warm, it may not be active, or it has
not been exposed to AMG and oxygen. Replace it with the second catalyst cartridge
included with the BACTRON. Reactivate the first cartridge.
a. Please see the Reactivating the Catalyst procedure on page 54.
Note: Use caution when uninstalling the catalyst cartridge. The catalyst can grow hot during a purge
of the chamber.
12. Make sure anaerobic monitoring strip packets have not been opened prior to being placed
in the oxygen-free atmosphere of the chamber
