Which circumstances trigger the requirement for a hazmat security plan?

• A. Transporting hazmat in quantities and types defined by the security plan rule; carriers must implement and maintain the plan
• B. Any hazmat shipment
• C. Only international shipments
• D. Only air shipments

Answer: (A)

Security plan requirements apply when hazmat is transported in quantities and types defined by the security plan rule. In practice, a carrier must have and maintain a security plan if their hazmat shipments meet those thresholds; it isn’t needed for every hazmat shipment, and it isn’t limited to international or to air shipments. The rule targets the specific combination of material type and amount that triggers the need for documented security procedures, such as how shipments are handled, who has access, and how the carrier coordinates with a designated security contact. So the trigger is transporting hazmat in the quantities and types defined by the security plan rule.
