UN 2570 — Cadmium compound
Placard: Toxic. ERG Guide 154. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2570 At a Glance
UN 2570 (Cadmium compound) is listed as DOT Class 6 Toxic and is assigned to ERG Guide 154. Use this page to review placard data, common hazards, PPE notes, isolation context, first actions, and related UN numbers.
UN 2570 covers cadmium compounds, a variable toxic material category. Responders should identify the exact compound from the SDS and shipping papers before cleanup or disposal decisions.
Hazard overview: Cadmium compounds can cause serious toxic exposure, especially through dust or fumes. Heating may release highly toxic metal fumes, and residues can create long-lasting environmental contamination.
Response guidance: Avoid creating dust, isolate the area and contain runoff. Use dry or low-dust collection methods only when compatible with the SDS. Fire suppression should protect exposures while limiting contaminated runoff.
Firefighter training notes: Train crews on toxic metal dust control, decon corridor setup and environmental containment. Do not assume all cadmium compounds behave the same.
Regulatory context: UN 2570 is a Class 6 toxic transport entry for Cadmium compound. Exact compound identity, concentration and waste handling must be confirmed from shipping papers and SDS.
Storage & handling: Store closed in a dry toxic-material area away from acids, oxidizers and drains. Prevent dust release and keep incompatible materials segregated.
UN 2570 Quick Details
Common Hazards of UN 2570
- Cadmium compound entries cover variable toxic cadmium salts or compounds; exact behavior depends on the product.
- Dust, fumes or soluble residues can cause serious toxic exposure by inhalation, ingestion or skin contact.
- Fire or heating may release highly toxic cadmium oxide or other metal fumes.
- Some cadmium compounds may be corrosive or form harmful solutions in water.
- Runoff and residues can create severe environmental contamination.
- Dust generation increases inhalation and cross-contamination risk.
- Containers may rupture when heated.
Chemical Identity & Physical Properties
Appearance varies by compound, but many cadmium compounds are white to yellow powders or crystalline solids. Some may be soluble or hygroscopic.

| 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 |

PPE Requirements
Use SCBA for dust, fumes or unknown atmospheres. Wear impervious chemical protective clothing, gloves, boots and eye/face protection; decontamination is critical.
Isolation & Evacuation
First Actions for a UN 2570 Incident
- Call 911 and the emergency response number on the shipping papers.
- Keep unauthorized personnel away and avoid disturbing dust or powder.
- Stay upwind, uphill and upstream of dust, fumes and runoff.
- Avoid breathing dust or fumes; prevent skin and eye contact.
- Do not touch damaged containers or spilled material without chemical-resistant PPE.
- Ventilate confined spaces only with trained hazmat personnel, SCBA and monitoring.
- Use ERG 154, SDS and shipping papers to identify the exact cadmium compound and controls.
