Labeling Solid Materials

Railroad ties
Railroad ties – good example of solid materials needing an SDS

For solid metal (such as a steel beam or a metal casting), solid wood, or plastic items that are not exempted as articles due to their downstream use, or shipments of whole grain, the required label may be transmitted to the customer at the time of the initial shipment, and need not be included with subsequent shipments to the same employer unless the information on the label changes.

For example, treated lumber is covered since the lumber is not completely cured at the time of shipment and the hazardous chemical will, to a varying degree, offgas during shipment and be available for exposure to employees. Railroad ties treated with creosote should have an accompanying safety data sheet (SDS) when shipped.
