NAVFAC P-300 Management of Transportation Equipment

. Surveillance. In all instances where containers, empty or packed, are
exposed to direct weather and sunlight, the frequency and type of surveillance on
containers must be increased to prevent weather and water damage.
c. Hardstands. Hardstands are recommended for all nontemporary storage
to ensure that containers do not stand for any period of time on uneven, unlevel footing
or in water and mud. The preferred handling and storage surface is concrete, provided
it meets appropriate design specifications for loaded containers. See NAVFAC P-1051,
Container Operations Manual, for specific requirements.
12. Preservation And Surveillance. Preservation procedures require that both the
container and its contents be protected from deterioration. Deterioration is primarily
caused by rust and corrosion due to moisture. Scheduled inspection of containers and
their contents on a cyclical basis is required to ensure adequate protection from the
environment. Surveillance is to serve as a review of the overall container condition.
a. Primary Method of Preservation. Controlled humidity is the primary
method of preservation for stored containers and container contents. Installed in each
container is a humidity indicator (NSN 6885-00-618-1822). When the humidity level is
at or over the 40 percent level, containers will require opening, contents checked for
rust, rust deteriorated contents replaced, and new desiccant placed in the container
prior to closing the container doors.
b. Desiccant. Use Type 1 and 2 Desiccant, MIL-D-3464, NSN 6850-00-264-
6573 or NSN 6850-00-264-6571, in either 2-unit packages, 8-unit bags, or 16-unit
bags. Place the desiccant in drawers, on shelves, and in boxes prior to closing and
sealing the containers. The containers, with closed vents and doors, are then stored in
a warehouse or covered storage until needed.
c. Surveillance Program. The surveillance program for containerized
materials and the containers requires various degrees of monitoring, depending on
local conditions. Some Activities will find it necessary to monitor the humidity indicator
on the door more closely to ensure the humidity level remains under the NAVFAC 40
percent recommendation.
d. Doors and Vents. Once containers reach their area of operation,
container doors and vents will be opened to accommodate day-to-day operation
whereby desiccant may be used as each unit deems necessary. Funding and
procurement of rust deteriorated contents, replacement humidity indicators, and new or
recharged desiccant is the responsibility of each Activity.
13. Alteration, Repair, And Maintenance. ISO containers are designed for the
specific purpose of intermodal shipping, and even minor modifications could prevent a
container from being used for its intended purpose.
