UN 2570 Quick Details
UN 2570
Product name: Cadmium compound
DOT Class: 6
Placard type: Toxic
ERG Guide: 154 (check current ERG)
Initial isolation: ERG 154: Initial isolation 25m all directions; protective action distance 0.8km downwind (daytime large spill); greater distances if fire involves material due to toxic fume generation
Common Hazards of UN 2570
- TOXIC and/or CORROSIVE; inhalation, ingestion or skin contact with material may cause severe injury
- Contact with molten substance may cause severe burns to skin and eyes.
- Avoid any skin contact.
- Fire may produce irritating, corrosive and/or toxic gases.
- Runoff from fire control or dilution water may be corrosive and/or toxic and cause environmental
- Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive
- Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.).
- Corrosives in contact with metals may evolve flammable hydrogen gas.
Chemical Identity & Physical Properties
| Also known as | Cadmium saltsCadmium compounds NOSCadmium derivativesCadmium chemicals |
| Appearance | Appearance varies by specific compound: typically white to yellow crystalline solids or powders. Most are odorless. Some compounds may be hygroscopic. |
| Flash Point | Not applicable (inorganic solid compounds) |
| Boiling Point | Varies by compound; many decompose before boiling (e.g., CdO decomposes ~900°C) |
| Vapor Density | Not applicable (solid compounds, though some may release toxic fumes when heated) |
| Water Reactivity | Generally stable in water, though some compounds are water-soluble and may hydrolyze; no violent reaction expected |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 2570
Extinguishing Media
Dry chemical, soda ash, lime; avoid generating dust during suppression
PPE Requirements
⚠️ Level B minimum with full respiratory protection; SCBA mandatory due to extreme inhalation toxicity; impervious suit required to prevent any skin contact; decontamination critical
Isolation & Evacuation
ERG 154: Initial isolation 25m all directions; protective action distance 0.8km downwind (daytime large spill); greater distances if fire involves material due to toxic fume generation
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 154).
First Actions for a UN 2570 Incident
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Ventilate closed spaces before entering, but only if properly trained and equipped.
- Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
