Which statement about the transport index is correct?

• A. It tells the degree of control needed during transportation
• B. It tells the exact chemical formula
• C. It tells the shipping route
• D. It tells the packaging size

Answer: (A)

Transport index is a numeric value used to indicate the level of control and safety measures required during transit. It guides shippers, carriers, and emergency responders about handling, segregation, stowage, exposure limits, and regulatory requirements for the shipment. A higher transport index means stricter controls. It does not convey the chemical formula, the shipping route, or the packaging size; those details come from other parts of the labeling or shipping papers. Understanding the transport index helps ensure hazmat shipments receive appropriate precautions.
