3. Transfer of hazardous materials must be in a work area segregated from incompatible
materials. Equipment must be used for compatible materials only.
4. Incompatible conditions (e.g., ignition sources, water) must be eliminated from recoupment
5. During transfer operations, ventilation systems (including local exhaust hoods) shall be
activated, and to assure that a proper airflow is maintained, doors to the work area shall be kept
6. When using local exhaust hoods, recoupment personnel should position package openings
as close as possible to the hood's intake vent.
7. Recoupment personnel should assure that they have a clear emergency egress route during
all phases of recoupment operations. Exit routes must not be blocked by equipment, debris, or
materials being processed through the recoupment facility.
8. Transfer operations of liquids should assure that splashing of the material does not occur.
9. Transfer operations of volatile materials should assure that hazardous concentrations do not
accumulate in the workroom and that appropriate control measures for hazardous waste air
emissions as specified in 40 CFR, Part 264 are implemented when appropriate.
10. Transfer operations should assure that dispersion of powdered material does not occur.
11. Transfer operations of flammable or shock-sensitive materials should assure that friction
does not occur and that a static charge does not build up. All equipment and packages should be
grounded or bonded during recoupment of these materials as directed in section VII paragraph
4.37.K.2.b.2 and in NFPA 77.
12. If the specifications of a material have changed due to transfer operations (e.g., remnants
of a 55-gallon drum were transferred to 5-gallon cans), recoupment personnel should assure that
a new and appropriate NSN is assigned, and that action is taken to label new packages with the
correct NSN, manufacturer's name or CAGE and part number/trade name and to make necessary
adjustments to stock records.
13. New packages and their labeling must conform to DOT regulations (Title 49 CFR, parts
171 through 178) and to NSN specifications. Only package configurations that have been tested
to performance oriented packaging specifications may be used to package hazardous materials.
4.40 Decontamination and Cleanup
A. After recoupment is complete and at the end of each workday, appropriate cleanup and
decontamination procedures should be followed to assure that waste generated during operations
is disposed of properly and that recoupment personnel are not exposed to hazardous residues.
