Initial Inspection/Disposal Criteria

1. Separate tanks by NFES number. Inspect for punctures, tears.  Look for damaged couplings, and drain plugs.  Inspect flanges and make sure threads are not damaged.
2. Ensure ball bearings on fitting are working properly.  Repair or lube if necessary.
3. Inspect seal around flange.  Replace to 2 ½” female flange if tank return is equipped with fittings other than.
4. Return to stock if unused.
5. Refurbish item if tears and holes are repairable with local equipment and expertise.  Contact manufacturer for repairs requiring materials or skills not found at the local cache to determine if it is economically feasible to have manufacturer repair tank.
6. Dispose of item if unable to refurbish.

Refurbishing Procedures
