Unformatted text preview: gel is a satisfactory desiccant and is commonly available. Coating With a Preservative
D-56. Personnel may apply a light coat of oil to weapons, tools, and other items with unpainted metallic
surfaces. A coat of paint may suffice for other metal items. Wrapping
D-57. After completing the drying and coating, the packager wraps the cache items in a suitable material.
The packager ensures the wrapping is as waterproof as possible. He wraps each item separately to prevent
one perforation in the wrapping from exposing all items in the cache. The wrapping should fit tightly to
each item, eliminating air pockets. The packager also seals all folds with a waterproof substance. Packing
D-58. The packager must observe the following rules when packing items in the container: Remove all moisture from the interior of the container by heating or applying desiccant. Pack a
long-lasting desiccant inside the container to absorb any residual moisture. If the packager uses
silica gel, he must calculate the required amount by using the ratio of 15 kilograms of silica gel
to 1 cubic meter of storage space within the container. (This figure is based on the assumption
that the container is completely moisture-proof and the contents are slightly moist when
inserted.) Therefore, the ratio allows an ample margin for incomplete drying, and the packager
can reduce the amount if he knows the drying process was highly effective. Eliminate air pockets as much as possible by tightly packing items. The packager should use
thoroughly dried padding liberally to fill air pockets and to protect the contents from shock. If
possible, he should use clothing and other items for padding, which the recovery party may find
useful. Items made of different metals should never touch, since continuous contact may cause
corrosion through electrolytic action. Enclosing Instructions for Using Cached Equipment
D-59. The packager includes written instructions and diagrams if they facilitate the assembly or use of
cached items. Instructions must be written in a language that recovery personnel can understand. T...
