Precast Inc. - November/December 2008 - (Page 64) It is important that all storage areas are of sufficient size to allow the storage of prestressed members and for the maneuvering of lifting or handling equipment around these areas. It should be reasonably level and with enough ground support to withstand the weight of the elements placed upon it. Dunnage should be provided as support in the designated points, and they should be placed directly above each other as material is stacked, taking into consideration that the lowest casted members can and will support the stack load imposed on them. In its publication SHIB 02-10-2004, OSHA calls attention to the hazards of finger rack storage systems for concrete panels. Finger racks are long racks, usually 80 or more feet in length, where panels are stored in the upright position and held in place by pins and wedges. Following a fatal accident investigated by the OSHA Denver office, safety recommendations were issued for such storage systems. Some of them are listed below: • Ensure a professional engineer reviews and provides specifications for the storage system. • Place dunnage under every panel in at least two locations. • Design the pins so that they are of a consistent size and shape to ensure proper placement during installation, and that they are also restrained from horizontal displacement once installed. One way of restraining movement would be to install a clevis pin. • Do not perform any patching or finishing work on the panels while stored in the rack. • Mark the racks to indicate design capacities such as height, length and weight of panels. • Establish, communicate and enforce proper storage procedures. It is highly recommended that every prestressing plant using this form of storage system obtain a copy of this document at www.osha.gov/dts/shib/shib021004.html and review its contents. It must be noted that any employee working at a prestressing plant must be trained on all safety procedures and equipment operation, and that those procedures should be in writing and available as recommended in the NPCA Quality Control Manual. By following regulations, applying best practices and using some common sense, we can eliminate most of the hazards and achieve a safer workplace.
