606 Hazard Communication for the Employee
Skip to main content

Labeling Solid Materials

For solid metal (such as a steel beam or metal casting), solid wood, or plastic items that are not exempted as articles because of their downstream use, or for shipments of whole grain, the required label may be transmitted with the initial shipment or with the SDS provided before or with the first shipment. The information does not need to accompany later shipments to the same employer unless it changes.

Chemicals on treated wood may off-gas during shipment, creating a potential exposure.

This exception to requiring labels on every container of hazardous chemicals is only for the solid material itself, and does not apply to hazardous chemicals used in conjunction with, or known to be present with, the material and to which employees handling the items in transit may be exposed (for example, cutting fluids or pesticides in grains).

For example, treated lumber may be covered when it is not completely cured and a hazardous chemical may off-gas during shipment, exposing employees who handle it.
