CHAPTER 2

PREPARATION INSTRUCTIONS FOR STORAGE AND SHIPMENT

2-1. General

This chapter provides procedures for implementing the general policy on preservation and packing as it applies

to depot packaging, depreservation, and field packaging. Prepare ion instructions described herein include

cleaning, drying, preservative application, and the use of wrappings, cushioning, and containers as required.

Cleaning, drying, application of preservatives, and sealing of barriers should progress in an uninterrupted series

of operations. Each item will be processed according to the procedure outlined in the applicable preparation

instructions provided in the appendixes. Each preparation instruction includes a table which lists the materials

in national stock number (NSN) sequence required to process one unit of the item identified on the sheet.

2-2. Cleaning and Drying

Cleaning.

Prior to application of preservation and packing materials, items

shall be cleaned to remove corrosion, soil, and grease. Disassembly of complex assemblies shall be limited to

the degree necessary to assure that critical functioning surfaces are free of contamination. Pressure spray

methods shall be used only for items of relatively simple construction, all surfaces of which can be reached by

the spray. Cleaning will be accomplished by any process or combination of processes that will thoroughly clean

without damaging the item. The walls and floors of vans and shelters will be wiped or swept clean of dust, sand,

or other contaminants prior to cleaning installed equipment. Surfaces to which tape is to be applied will be

thoroughly cleaned of dirt, grease, and oils as well as other contaminants.

Drying.

Immediately after cleaning, thoroughly dry the items by using dry compressed air or by

wiping with clean, dry, lint-free cloths.

2-3.

Preservation Application

Apply preservative oils and greases by spraying, fogging, dipping, or brushing. When the dipping method is

used, allow parts to drain dry; when spraying, fogging, or brushing procedures are used, apply a complete

coating. Keep handling to a minimum after application to avoid disturbing the preservative coating. When

preparation procedures do not stipulate the types of preservatives to be used, select compounds whose

application, removal, or use will not damage the mechanism, structure, or function of the item.

2-4.

Unit Pack

Items that are going to be placed in a container shall be wrapped, cushioned, blocked, or braced to prevent

damage to the item or the container.
