UN 3323 Quick Details
UN 3323
Product name: Radioactive material, Type C package, non fissile or fissile excepted
DOT Class: 7
Placard type: Radioactive
ERG Guide: 163 (check current ERG)
Initial isolation: ERG 163: intact packages minimal isolation; damaged packages isolate 25m minimum, notify radiation authority immediately, increase distance based on radiation readings
Common Hazards of UN 3323
- Radiation presents minimal risk to transport workers, emergency response personnel and the public
- Undamaged packages are safe. Contents of damaged packages may cause higher external radiation
- Type A packages (cartons, boxes, drums, articles, etc.) identified as Type A by marking on packages or
- Type B packages, and the rarely occurring Type C packages (large and small, usually metal), contain
- The rarely occurring "Special Arrangement" shipments may be of Type A, Type B or Type C packages.
- Radioactive White-I labels indicate radiation levels outside single, isolated, undamaged packages are
- Radioactive Yellow-II and Yellow-III labeled packages have higher radiation levels. The transport index
- Some radioactive materials cannot be detected by commonly available instruments.

Fireground Response Guidance — UN 3323
Extinguishing Media
Water spray for cooling if fire exposure; do not apply water directly to damaged packages without radiation authority approval
PPE Requirements
⚠️ Intact packages require minimal PPE; damaged packages require time-distance-shielding protocols, dosimetry, and radiation safety officer guidance per emergency plan
Isolation & Evacuation
ERG 163: intact packages minimal isolation; damaged packages isolate 25m minimum, notify radiation authority immediately, increase distance based on radiation readings
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 163).
First Actions for a UN 3323 Incident
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Priorities for rescue, life-saving, first aid, fire control and other hazards are higher than the
- Radiation Authority must be notified of accident conditions. Radiation Authority is usually responsible for
- Stay upwind, uphill and/or upstream. • Keep unauthorized personnel away.
- Detain or isolate uninjured persons or equipment suspected to be contaminated; delay decontamination
- Isolate spill or leak area for at least 25 meters (75 feet) in all directions.
- Consider initial downwind evacuation for at least 100 meters (330 feet).
