1 (Cancels G.I.S. No. 690) Doorway Protection for Baled Paper Products in Boxcars Approved by DAMAGE PREVENTION & FREIGHT CLAIM COMMITTEE Association of American Railroads Issued November 2014 Published by AAR/TTCI Damage Prevention and Loading Services DOT Road Pueblo, CO (Printed in U.S.A.) 2014

2 2 GENERAL RULES The General Rules relating to personal safety and the safe operation of trains, contained in AAR Circular Nos. 42-K and 43-E or supplements thereto, issued by the Association of American Railroads, must be observed. These loading rules and/ or practices apply to shipments transported in the USA, Canada and Mexico. The loading methods, in individual closed car loading publications issued by the Damage Prevention and Freight Claim Section of the Association of American Railroads, are minimum standards that have been evaluated and approved. These minimum standards offer practical guidelines on the subjects covered. Since these are minimum standards, it may be necessary to supplement these methods in some instances. Securement standards in AAR closed car loading publications are intended for safe transit of the rail car from origin to destination and prevention of lading and equipment damage. These standards do not address unloading practices. Loading and bracing methods not presently approved may receive consideration for approval and publication under the "Damage Prevention and Freight Claim Section Procedures Governing Evaluation and Acceptance of New Closed Car Loading and Bracing Methods and Materials." Submit requests to Director Damage Prevention and Loading Service,s AAR/TTCI, DOT Road, Pueblo, CO 8100,. CAUTION: Car rocking motion caused by lift equipment entering and/or exiting the rail car may cause unsupported packages or articles with a high center of gravity to fall to the floor. Minimize access to the car. Exercise caution when inside a partially loaded car. Lift operators should stay on lift equipment, whenever possible, while inside a partially loaded car. I. GENERAL When loading bales in the doorway area take care not to apply pressure on doorway straps installed in the off-loading doorway. This typically occurs when bales are pushed or placed against the doorway straps by mechanical handling equipment. It can result in the doorway straps being pushed out to the doors and the lading contacting the doors. General information on doorway protection is also available in AAR Closed Car Loading Guide Part 1, Minimum Loading Standards for Freight in General Purpose Boxcars.

3 3 II. STEEL STRAPPING Steel strapping may be used as doorway protection in boxcar shipments of baled paper products. Use one 1¼ in. x.029 in. steel strap per layer in each doorway. Illustration No. 1 shows the typical application for steel straps used as doorway protection for a load with three layers in the doorway. Strap Ends Tensioned and Sealed Conventional Doorway Application Illustration No. 1 Conventional Doorway Application: Steel straps are anchored to opposite door post anchors, and brought together under tension and sealed. Install straps on the doorposts of the loading side doorway before loading. These straps are draped outside the car until loading is completed and then tensioned and sealed across the doorway.

4 4 III. POLYESTER CORD STRAPPING The polyester cord strapping/buckle systems listed in the following table have been approved for use as doorway protection in boxcar shipments of baled paper products. These applications are approved as alternatives to use of one 1¼ in. x.029 in. steel strap per layer in each doorway. ASTM Type and Grade* Type IA, Grade 3 Type IA, Grade 4 Type IA, Grade 5 Size 1¼ in. Wide 1¼ in. Wide 1½ in. Wide Application - See Illustrations 2 & 3 2 Straps - top layer 1 Strap each lower layer 1 Strap per layer 1 Strap per layer Type IA, Grade 4 1¼ in. Wide Doorway Unitization See Illustration No. 3 * See ASTM Standard D3950, Standard Specification for Strapping, Nonmetallic, for information on strapping type and grade, and testing procedures. The strap is to be clearly marked with the Strap I.D. in accordance with the strap marking requirements of AAR Circular 42-I, General Rules Covering the Loading of Carload Shipments of Commodities in Closed Cars. The straps are to be tensioned and joined using the correct buckle and tensioning tools in accordance with manufacturer s instructions. It is important that the buckle be applied properly to maintain strap tension.

5 5 Strap Ends Tensioned and Sealed Illustration No. 2 : In a belt type application a strap is threaded through anchor points on opposite doorposts and brought together under tension at a buckle or seal. The loading side straps can not be installed until loading has been completed. If bales are in contact with the doorposts on the loading side after loading is completed, it may be difficult to install the doorway straps after loading. If this is the case, install individual pieces of strap through the anchors on the both doorposts at the appropriate heights prior to loading adjacent to the doorposts. After completing loading it will be necessary to bring one end of each strap at a given height together in a buckle, then tension the remaining two ends and apply a second buckle. Insert a short length of strap between the doorpost anchors and the doorway straps to act as a buffer.

6 6 Unitizing Straps Doorway Unitizing Application Illustration No. 3 Doorway Unitizing Application: This application is limited to loads where the lengthwise doorway stacks fill the entire door opening. Use a minimum of two vertically oriented straps as shown for a single stack in the doorway area. If there is more than one stack completely in the doorway area, use two straps per stack.
