What must be placed on items that are considered dangerous goods?

When it comes to items classified as dangerous goods, the regulations specify that they must have ORM-D labels. "ORM-D" stands for "Other Regulated Materials for Domestic transport" and is a designation used to indicate materials that pose limited risk during transportation. This labeling is crucial as it serves to inform handlers and transport personnel of the potential hazards associated with these materials, ensuring they are treated properly and safely throughout the shipping process.

In contrast, while warning labels, flammable warnings, and handling instructions may be relevant for other categories of goods, they do not specifically denote the items classified as ORM-D. ORM-D labels have a specific regulatory meaning and usage, making them the appropriate choice when identifying dangerous goods that fall under this particular classification. Using the correct label not only complies with federal regulations but also enhances safety during transport.
