various other local operating conditions. In addition to basic layout factors, the requirement for
the segregation of incompatible materials must be considered. While a separate packaging line is
not required for each hazard class or HCC, strict precautions must be taken to reduce the
possibility of accidental co-mingling of incompatible materials during this phase of the operation.
6.9 Pack Area and Inspection. Immediately after the material is moved to the pack area, it will
be inspected for damage that may have occurred during stock selection or subsequent movement
from the storage area to the packaging operation. Installation employees performing this
inspection must be aware that their failure to identify and correct deficiencies at this time may
cause additional hazards during transportation. If inspection discloses that the damage or
deficiency is minor (e.g., obliterated labels or markings, minor package abrasions or tears, etc.)
and the material is not a pesticide, it may be moved directly to the packaging operation where
required repairs will be made. In the case of pesticides, corrective action will be taken in
accordance with Chapter 3, Section VIII, Paragraph 3.22 of this document. In the event of
substantial package damage or evidence of leaks or suspected leaks, the supervisor will be
notified and spill response procedures initiated in accordance with Chapter 7 of this document.
SECTION III. PACKAGING, MARKING, AND LABELING OF HAZARDOUS MATERIAL
6.10 General Packaging Requirements
A. The general packaging requirements for hazardous materials are outlined in Title 49 CFR,
Section 173.24. Each package used for the shipment of hazardous materials shall be designed,
constructed, maintained, filled, and closed so that under normal conditions of transport:
1. There will be no identifiable release of hazardous material to the environment.
2. The effectiveness of the package will not be substantially reduced. That is, impact
resistance, strength, and packaging compatibility must be maintained for minimum and
maximum temperature changes encountered during transport.
3. There will be no mixture of gases or vapors in the package which could through increase of
heat or pressure significantly reduce the effectiveness of the packaging.
B. Outage and Filling Limits. When packagings or receptacles are filled with liquid hazardous
materials, sufficient ullage (outage) must be left to ensure there is no leakage or permanent
distortion of the packaging or receptacle as a result of expansion due to temperature changes
encountered during transportation. Liquids must not completely fill a receptacle at a temperature
of 55o C (131o F) or less.
C. Authorized Packagings. A package is authorized to contain a hazardous material only if the
packaging is cited in the specific packaging section in Column 8 of the 49 CFR 172.101 Table
for that material and conforms to the special provision requirements of Column 7 of the 172.101
Table. Specification packagings (including UN standard packagings) must meet the
