UN 2919 Quick Details
UN 2919
Product name: Radioactive material, transported under special arrangement, non fissile or fissile-excepted
DOT Class: 7
Placard type: Radioactive
ERG Guide: 163 (check current ERG)
Initial isolation: ERG 163: isolate spill or leak area immediately for at least 25-50m in all directions; damaged packages increase isolation distance; evacuate area if dose rates elevated; contact radiation authority
Common Hazards of UN 2919
- 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.
Chemical Identity & Physical Properties
| Also known as | Radioactive material special arrangementRAM special arrangementType A radioactive packageNon-fissile radioactive materialFissile-excepted radioactive material |
| Appearance | Varies widely; typically solid materials packaged in Type A containers (drums, boxes, cartons). May include contaminated equipment, sealed sources, or medical/industrial isotopes. No characteristic color or odor. |
| Flash Point | Not applicable (radioactive hazard, not flammability) |
| Boiling Point | Not applicable (depends on specific material) |
| Vapor Density | Not applicable (typically solid forms) |
| Water Reactivity | Generally no significant reaction; specific material dependent |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 2919
Extinguishing Media
Not applicable for fire suppression; radiation hazard primary concern, use appropriate extinguishing agent for packaging material if fire occurs
PPE Requirements
⚠️ Radiation detection equipment required; time/distance/shielding principles; damaged packages may require Level C with dosimetry; minimize exposure time and maximize distance
Isolation & Evacuation
ERG 163: isolate spill or leak area immediately for at least 25-50m in all directions; damaged packages increase isolation distance; evacuate area if dose rates elevated; contact radiation authority
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 163).
First Actions for a UN 2919 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).
