Which regulations should a unit have access to when preparing HAZMAT for transportation on OCONUS military air?

• A. TM 38-250 and IATA DGR
• B. TM 38-250 only
• C. IATA DGR only
• D. Army Hazardous Materials Manual

Answer: (A)

When preparing hazmat for air transport, you must follow regulations that cover both the DoD/Army requirements and international air transport rules. TM 38-250 provides the Army’s specific packaging, labeling, documentation, and acceptance procedures for hazardous materials, ensuring the shipment meets military standards. IATA DGR gives the internationally recognized rules for how dangerous goods must be classified, packaged, labeled, and documented for air carriage by airlines and carriers worldwide. For OCONUS military air, carriers and authorities expect compliance with both sets, so the best practice is to consult both TM 38-250 and IATA DGR. Relying on only one source could leave gaps in DoD-specific requirements or in airline/international expectations.
