Chemical & Response Details
| Also known as | Radioactive material excepted packageLimited quantity radioactiveExcepted radioactive packageRAM excepted packageType A excepted radioactive material |
| Appearance | Variable physical state and appearance depending on specific material; minimal radioactivity present in small quantities that pose minimal risk during transport. Packaging meets excepted requirements with very low activity levels. |
| Flash Point | Not applicable (varies by specific radioactive material content) |
| Boiling Point | Not applicable (varies by specific radioactive material content) |
| Vapor Density | Not applicable (varies by specific radioactive material content) |
| Water Reactivity | Generally no significant reaction; depends on specific chemical form of radioactive material |
| Extinguishing | Not applicable for radiation hazard; use appropriate extinguishing media for any secondary fire hazard based on material composition |
| PPE | ⚠️ Minimal PPE required due to low radiation levels; standard protective clothing, gloves recommended; radiation detection instruments may not detect low levels; follow standard precautions |
| Isolation | ERG 161: No evacuation required for excepted packages; if damaged, isolate area and notify radiation authority; minimal public hazard due to very low activity levels |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- Radiation presents minimal risk to transport workers, emergency response personnel and the public
- Very low levels of contained radioactive materials and low radiation levels outside packages result in low
- Some radioactive materials cannot be detected by commonly available instruments.
- Packages do not have RADIOACTIVE I, II, or III labels. Some may have EMPTY labels or may have the
- Some of these materials may burn, but most do not ignite readily.
- Many have cardboard outer packaging; content (physically large or small) can be of many different
- Radioactivity does not change flammability or other properties of materials.
First actions (field-minded)
- 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).
