1 General Information Series No. 756 (Cancels G.I.S. No. 751) Non-metallic Strap Substitution for Steel Strap as Doorway Protection in Boxcars Approved by DAMAGE PREVENTION & FREIGHT CLAIM COMMITTEE Association of American Railroads Issued January 2017 Published by Association of American Railroads/TTCI Damage Prevention and Loading Services DOT Road Pueblo, CO (Printed in U.S.A.)

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 Loading Services 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. These loading methods were tested under simulated conditions. This approval may be withdrawn if the loads using these methods exhibit consistent load failure during actual shipments. Loading and bracing methods not presently approved may receive consideration for approval and publication under Section II - Evaluation of New Loading and Bracing Methods and Materials for Closed Cars, Trailers or Containers of General Information Bulletin No. 2, Rules and Procedures for Testing of New Loading and Bracing Methods or Materials. Submit requests to Director Damage Prevention and Loading Services, AAR/TTCI, DOT Road, Pueblo, CO 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.
