applicable, local disposal direction, and other selected management data. The MRIL must be used in conjunction with the Supply Afloat Packaging Procedures, NAVSUP P-484, and Afloat Supply Procedures, NAVSUP P-485, for all afloat activities and MILSTRIP/MILSTRAP, NAVSUP P-437, and the Material Turned In To Store (MTIS) Manual, NAVSUPINST 4440.157, for ashore activities. The MRIL is published on microfiche by the FMSO and distributed monthly to all ships and shore activities that use or process repairable. Each edition supersedes the previous edition and the old microfiche should be discarded except for the introduction which is published and distributed quarterly. The MRIL is divided into two parts. Part I contains NSNs and NICNs of repairable items and aircraft engine type/model/series identifiers. It also contains information required to make repair or turn-in determinations on repairable and aircraft engines. NSNs and NICNs listed in this part are in NIIN sequence. Part II contains addresses of DOPs including contractors and other indicated destinations for all items listed in part I. Addresses are listed in shipping code sequence. Items that are either in long supply or are authorized to remain in place are indicated, and the NIIN of specially designated reusable shipping containers for returning the repairable component is identified. Hazardous Material Information System The Hazardous Material Information System (HMIS) provides information to assist users in managing hazardous materials so that the risk involved in the performance of various jobs is minimized. The HMIS provides a wide range of data related to safety, health, packaging, labeling, transportation, and disposal of hazardous material. It also provides stowage and handling safety precautions. The HMIS is in microfiche format and is issued quarterly by NAVSUPSYS- COM. List of Items Requiring Special Handling The List of Items Requiring Special Handling (LIRSH), NAVSUP P-4105, is published to identify items that require special handling. The LIRSH is a reference publication used in conjunc- tion with other publications, such as the MRIL and/or HMIS. Categories of items listed include repairable items, shelf-life items (deteriorative in nature), physical security code items (for special handling), and hazardous items. The LIRSH is published quarterly to coincide with the ML-N. Interim updating of elements such as NSN, repairable, security, shelf-life, and shelf-life action code data is provided via change notice cards/tapes to all applicable activities. Distribu- tion of the LIRSH is controlled by the FMSO. Afloat Shopping Guide The Afloat Shopping Guide (ASG), NAVSUP P-4400, is designed to assist fleet and all Navy supply support personnel in identifying the NSN items that are most frequently requested by ships. It includes a detailed description of each item, a specific code to designate items carried by combat logistics force (CLF) ships, and when applicable, stock numbers of substitute items, The ASGs also include specifications, illustrations, or diagrams of several types of materials. The ASGs contain six sections as follows: Federal Supply Group/ Section Federal Supply Class (FSG/FSC) 1 2040 to 4930 2 5110 to 5680 3 5905 to 5990 4 6135 to 7360 5 7510 to 8470 6 9150 to 9920 To obtain management data for those NSNs listed, the ML-N should be consulted for current information on unit of issue, unit price, and other pertinent supply management data required to requisition the item. This publication is updated as required. The ASG is distributed to all ships and Navy activities providing supply support within the Navy supply system. Identification Lists The Identification Lists (ILs) are developed and published by the DLSC to provide descriptive and illustrative data to identify or select items of supply used by all services. Therefore, various NSNs identified in the ILs are not listed in the ML-N. The ILs are updated either quarterly or semiannually, depending on the size of each. The ILs are distributed only to shore activities, load- carrying ships, and aircraft carriers. 1-14
