UN 2863 — Sodium ammonium vanadate
Placard: Toxic. ERG Guide 154. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2863 At a Glance
UN 2863 (Sodium ammonium vanadate) 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.
Sodium ammonium vanadate is a toxic inorganic vanadium compound handled as a solid. Response priorities are dust control, exposure prevention, and runoff containment.
Hazard overview: The solid is not a simple fire hazard, but dust, contaminated solutions, and heated decomposition products can injure responders or spread contamination.
Response guidance: Isolate the spill, avoid sweeping that creates dust, and use wet methods only when runoff can be contained. Protect crews from dust and fumes during fire exposure.
Firefighter training notes: Training should cover toxic dust/vapor control, decontamination, runoff containment, respiratory protection, and SDS-based exposure precautions for UN 2863.
Regulatory context: Confirm the exact shipping description, hazard class, packaging, SDS, and ERG 154; disposal and cleanup may require hazardous-waste controls.
Storage & handling: Store tightly closed in a dry, labeled area away from food, incompatible materials, and conditions that could spread dust, vapor, or contaminated runoff.
UN 2863 Quick Details
Common Hazards of UN 2863
- Toxic and corrosive vanadate solid; inhalation, ingestion, or skin contact can cause severe injury.
- Dust can irritate or damage respiratory tissues and eyes.
- Dissolved material forms toxic solutions that can spread contamination.
- Heating may produce irritating and toxic vanadium-containing fumes.
- Nonflammable itself, but fire exposure may rupture containers.
- Avoid generating dust during spill control.
- Contaminated runoff should be contained for proper disposal.

PPE Requirements
Use SCBA or full-face respiratory protection, chemical-resistant clothing, gloves, boots, and eye protection; avoid contact with dust or solutions.
Isolation & Evacuation
First Actions for a UN 2863 Incident
- Call 911 and the emergency response number shown on shipping papers or the SDS.
- Keep unauthorized personnel away and prevent dust, vapor, or runoff from spreading.
- Stay upwind, uphill, and upstream; avoid breathing dust, fumes, or fire gases.
- Avoid all skin and eye contact with powder, liquid, solutions, or contaminated clothing.
- Do not touch damaged containers or spilled material without chemical-resistant PPE.
- Control runoff and keep material out of drains, soil, and waterways.
- Use ERG guidance, SDS, shipping papers, and exposure monitoring before cleanup.
