UN 2917 Quick Details
UN 2917
Product name: Radioactive material, Type B(M) package, non fissile or fissile-excepted
DOT Class: 7
Placard type: Radioactive
ERG Guide: 163 (check current ERG)
Initial isolation: ERG 163: isolate 25m all directions initially; damaged packages isolate 80m and evacuate 300m downwind; secure area and await radiological assistance
Common Hazards of UN 2917
- 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 2917
Extinguishing Media
Do not apply water or foam unless directed by radiation authority; use distance and shielding
PPE Requirements
⚠️ Respiratory protection and full protective clothing required for damaged packages; dosimetry required; consult radiation safety officer
Isolation & Evacuation
