Shipping Containers Authorized for IPE

TM 38-260

(2) Blocking and bracing. Items which do not completely fill the shipping container shall be blocked, braced,

anchored, or otherwise immobilized within the container. Items or movable parts of items mounted on springs or other

flexible supports shall be braced securely to prevent movement, except where such mounting is part of the package

cushioning or is designed to protect against shock and vibration during shipment. The materials selected for all blocking

and bracing shall be compatible with the load to be supported and the size, shape, and strength of bearing areas of the

item.

(3) Anchoring. Anchoring of heavy items shall be accomplished by securing the item to a base by tension

devices, either by bolts through mount bolt holes on the item (bolting down), or by metal strapping, cables, tie rods,

chains, wire, or other tension devices attached to or applied over the item (tie down or hold down), or by both. The same

washer requirements as specified for bolts shall apply to tie rods in that the inside washer diameter shall be equal to the

diameter of the bolt or tie rod.

(4) Waterproofing. Waterproof liners, wraps, shrouds, or other suitable means shall be provided in shipping

containers as necessary to protect contents against entry of free water. Such protection, however, is not necessary when

items, dunnage, exterior cushioning, and interior packages are water-resistant or otherwise waterproofed. Waterproof

liners, wraps, shrouds, and other similar protection shall also be required when necessary to prevent the entry of dust,

dirt, and other foreign matter. All seams shall be completely and continuously sealed to provide water resistance

equivalent to that provided by the barrier material itself.
