What action should be taken before moving a HAZMAT shipment without the appropriate labeling?

Before moving a HAZMAT shipment, the appropriate labeling is crucial for ensuring safety and compliance with regulatory requirements. Taking corrective action to label the shipment properly before movement not only aligns with legal obligations but also protects individuals, the environment, and property from potential hazards. Proper labeling provides essential information to responders in case of an incident, helps in understanding the nature of the material being handled, and contributes to the overall safe transportation of hazardous materials.

Moving forward without the appropriate labeling poses serious risks, including potential accidents and regulatory penalties. This is why it is essential to stop and ensure that all HAZMAT shipments are correctly labeled prior to transport. The other options may suggest actions like waiting for approval or seeking legal counsel, but unless the shipment is appropriately labeled first, it should not be moved.
