TR-7, Guidelines for In-Plant Handling of Aluminum Plate, Flat Sheet and Coil (Second Edition, January 2006), describes procedures and methods that have been used successfully to handle sheet and plate in the plant, both manually and with equipment. It covers storage, handling, processing and inspection practices that protect the surface and edges of the material, including stacking and racking, the use of cranes, vacuum lifters and slings, protective interleaving, and the avoidance of mechanical damage and water staining. The document also includes a list of suppliers of safety equipment and apparel. It is used by warehouse and production staff and by safety and quality managers to write handling instructions that reduce damage and injuries.
