2. An internal visual inspection is performed. If any of the prior
contents remain after performance of the reconditioning process, or if
rust is evident, the drum is rejected or acid flushed to thoroughly remove
3. Chimes are mechanically straightened to reform and reseal them.
Drums are dedented using internal pressure sufficient to restore original
shape and contour.
4. The drum exterior is abrasive blasted to remove coatings, and corrosion.
The exterior surface is properly prepared for painting.
5. The thoroughly cleaned drum is leak tested by the state of the art
Wilco Vacuum Leak Proofness Tester. This is a D.O.T. approved test method.
Drums found to be leaking are rejected.
6. Before painting, drums must be inspected for deterioration and drums
having visible pitting,
significant reduction in apparent metal thickness
from rust, corrosion, or other material defects, or which have not been
returned to original shape and contour, must be rejected.
7. All closures must be removed, cleaned, and reinserted with suitable new

8. The drum must be painted with new exterior coating to provide a
protective and decorative finish.
9. The completed drum must be marked with Mitchell Container Services, Inc.
D.O.T. identification number, R-1355, and the month and year of testing.
To insure the highest quality the MCS final inspector and leakproofness
operators initial each drum processed. Drums marked in accordance with
the UN standards must include the nation in which the reconditioning was
performed, the letter "R", and the letter "L" for drums that have been
successfully leakproofness tested. If the original manufacturer's durable
full UN marking has been removed in the reconditioning process, it must be
replaced by the reconditioner before the drum may be used again to transport
hazardous materials. The reconditioners replacement mark may show a
performance level below that originally marked by the drum manufacturer,
but in no case may a reconditioner mark a higher performance level than was
embossed on the bottom of the drum as part of its original "birth certificate."
Mitchell Container's identity and R-1355 marking isa certification that the drum meets all applicable regulations.
