1.2 SCOPE 1.2.1 This procedure is applicable to all permanent plant (mechanical equipment, electrical equipment, and instrumentation) and bulk items such as pipe, valves, hangers, cables, conduit, ect.,
which Brown & Root is responsible to store and maintain from the time of on-site receipt until turnover to the Client, including-initial receipt, receipt of repaired items, and items returned to B&R by the Owner (Paragraph 5.0).
2.0 DEFINITION OF TERF6 AND NOTES Z
2.1 TERMS
. 2.1.1 Engineering - CPSES site engineering.
2.1.2 " Stored-in-Place" - Equipment is considered " Stored-in-Place" when it is stored in the general or immediate area of its per-manent location. Equipment may be preliminarily aligned and still be considered " Stored-in-Place".
3.0 CENERAL 3.1 The storage enviromental conditions for items are divided into i five types , (as type A, B, C, D, E, and exemplified in Appendix A) . '
These types are divided with respect to protective measures to prevent damage, deterioration or contamination of the items and are based upon the important physical characteristics and not upon the important functional characteristic of the item. It should be recognized, however, that within the scope of each type, there may be a range of controls and that the detailed requirements of an item are dependent on the importance of the
! item to safety or reliability. For example, even though a reactor vessel and structrual steel may be classified as type D, the degree of protection and control over the reactor vessel j
should exceed that of the structural steel. Any package unit or assembly made up of items of different types, shall be classified i to the highest type designated for any of the respective parts.
l If the unit is disassembled, a type shall be indicated for each
! part. The Equipment Maintenance Record (Attachment 1) shall
!
- specify the type of storage required. Items shall be stored as l
specified unless a higher type storage is used. The following attributes, as applicable, shall be observed and implemented in the storage areas:

dirt, and discarded packaging materials.
3.1.2 Measures shall be taken to prevent the entrance of rodents and other animals into indoor storage areas or equipment to mini-mize possible contamination and mechanical damage to stored material. Also, measures shall be taken to control entrance of insects into sensitive items such as instrumentation.
+
3.1.3 Ready Access to Stored Items - All items shall be stored in -
such a manner as to permit ready access for inspection or
' maintenance without excessive handling.
3.1.4 Arrangement of Items - Items shall be stored on dunnage, pallets, etc. , approximately 4" above the ground. Items, except piping material, stacked for storage shall be arranged so that racks, cribbing or crates are bearing the full weight without distortion of the item.
3.1.5 Storage of Hazardous Material - Hazardous chemicals, paints, solvents, and other materials of a like nature shall be stored in well ventilated areas.
,f 3.1.6 Identification - All items and their containers shall be V properly and plainly marked so that they are easily identified without excessive handling, or unnecessary opening of crates J and boxes, o 3 . '1. 7 Coverings - Weatherproof covering, when used for outdoor storage, i
shall be the flame-resistant type of sheeting or tarpaulins.
They shall be places so as to provide drainage and to insure air circulation to minmize condensation. They shall be tied down to prevent moisture from entering laps and to protect the cover-1 ings from wind damage. Items in storage shall have all covers, L caps, plugs, or other closures intact. Covers removed for internal k access at any time for any reason shall be immediately replaced and resealed after completion of the purpose of removal.

All items shall be properly drained to prevent water collection on the interior or exterior surfaces. These items shall be made ready for storage, as applicable, by capping, applying preser-vatives, grease or oil for extended storage. Outside warehouse storage preservation will be under surveillance by the Chief Warehouseman and/or designee and monitored by schedule for implementation. Carbon steel piping material or structural tubing shall not be capped. .
7 j/ 3.1.9 Material Segregation - Sensitive material such as stainless steel shall be stored in such a manner to prevent contamination by other material such as carbon steel, low melting alloys, chlorides, etc.
l 3.2 Equipment maintenance shall'normally begin within 30 days from.
receipt of equipment, and maintained monthly unless otherwise directed.
3.3 Craf t Superintendents responsible for maintenance shall coordinate with various departments (Engineering, Electrical, Building, Paint, Area Coordinator, ect.) for the appropriate assistance.
L 3.4 The craf t foreman shall notify QC of intended performance of maintenance prior to craft action.
3.5 Materials necessary to meet the storage and maintenance require-ments, e.g., desiccant, humidity indicator cards, nitrogen for purge, etc., shall be coordinated by the Craf t Superintendent and Engineering.
3.6 Items may be stored in place due to size, accessibility, scheduling, etc. Storage of pieces of equ'.pment and material in the immediate plant construction area should be limited to that necessary. Items taken from storage shall be either installed or " stored-in-place". Items taken from storage shall be maintained to conform with storage and maintenance requirements previously established unless otherwise specified on the Equipment Maintenance Record (EMR) . Items shall merit additional protection if construc-tion work threatening the integrity of equipment is in progress.
For example: If concrete' or structural work is in progress in the immediate vicinity, a wood or polypropylene shelter shall be erected around the item if necessay to protect it from damage or contamination.
