Protection From Environmental Hazards

TM 38-260

e. Storage-in-place. When IPE is to be stored-in-place, preparations shall be made immediately following or during

shutdown. Equipment shall remain in the original operating position connected to power. Preparation shall be in

accordance with the level specified. Exercising of equipment may be specified by the cognizant activity to maintain a

high level of readiness.

5-12.

Protection From Environmental Hazards

a. IPE stored under these environmental conditions can only be protected to the extent that a barrier between the

atmosphere and the surface of the equipment can be applied.

b. The barrier shall completely encompass the equipment in such a manner that the equipment is fully protected

from water, dirt, and other harmful foreign matter. This may be accomplished by shrouding the equipment with flexible

waterproof barrier material conforming to PPP-B- 1055, class E or heavier, or plastic strip, thin gauge polyolefin,

conforming to L-P-378, class i, type II.

(1) All covers shall be of sufficient strength to provide adequate protection throughout the storage period and

shall be secured in a manner to ensure that such protection is achieved.

(2)

Covers made from waterproof paper shall not be used.

(3)

All sharp corners and projections shall be padded or cushioned before shrouding.

(4) Shrouds shall be draped in such a manner as to completely cover the item. They shall be arranged to avoid

possible formation of water pockets. It is important that shrouds be secured to prevent damage or loosening during

storms. Shrouds should extend to approximately 6 inches (152 mm) from the base of the equipment to permit free

circulation of air over and around the equipment to prevent any sweating of the equipment.

c. When it is necessary to store IPE in open storage, it must be accepted that the effects of the atmosphere will

deteriorate those components of equipment which, because of their nature, cannot be provided with a barrier.

d. Rubber, electrical, and electronic systems and their components are examples of items which are particularly

vulnerable to the effects of noncontrolled atmosphere.

5-13.

Preservation Requirements

a. When it is necessary to store IPE in noncontrolled storage, the preservation requirements specified in chapter 4

shall apply.

b. The preservation specified in chapter 4 cannot be considered as an equal alternative to controlled humidity

storage when a choice between the two is possible. Equipment stored in noncontrolled storage with long-term

preservation also requires represervation, rehabilitation, repair, and replacement of components as the term of storage

extends.
