UN 2580 — Aluminum bromide, solution
Placard: Corrosive. ERG Guide 154. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2580 At a Glance
UN 2580 (Aluminum bromide, solution) is listed as DOT Class 8 Corrosive 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.
Aluminum bromide solution is a corrosive acidic liquid. Because concentration can vary, responders should confirm the SDS before dilution, neutralization or cleanup.
Hazard overview: Mist, splashes and fumes can cause severe burns. Concentrated solution may fume hydrogen bromide and can react exothermically when diluted or contaminated, creating acidic runoff.
Response guidance: Isolate the spill, keep personnel out of vapor and splash zones, and protect drains. Cool exposed containers with water spray from a safe distance, but do not perform neutralization or dilution unless trained and guided by the SDS.
Firefighter training notes: Training should focus on variable solution strength, acid-gas monitoring and controlled neutralization. Crews should avoid improvised dilution of concentrated corrosives.
Regulatory context: UN 2580 is Aluminum bromide, solution, Class 8 corrosive. Shipping papers and SDS should identify concentration, packaging and emergency contact details.
Storage & handling: Store in compatible corrosion-resistant containers with secondary containment. Keep away from bases, reactive metals, oxidizers and heat.
UN 2580 Quick Details
Common Hazards of UN 2580
- Corrosive aluminum bromide solution; liquid and mist can burn skin, eyes and respiratory tissue.
- Concentrated solution may release hydrogen bromide fumes, especially when heated or diluted improperly.
- Additional water or contamination can generate heat and acidic mist depending on concentration.
- Corrosive liquid may attack metals and can release flammable hydrogen gas.
- Fire exposure can produce irritating and corrosive bromide fumes.
- Runoff may remain acidic and harmful to waterways.
- Containers may rupture when heated.
Chemical Identity & Physical Properties
Aluminum bromide solution is typically a clear to pale yellow corrosive liquid with a pungent irritating odor. Appearance and strength vary by formulation.
| Also known as | Aluminum tribromideAluminium bromideTribromoaluminumAlBr3 solution |
| CAS Number | 7727-15-3 |
| Appearance | Clear to pale yellow solution with pungent, irritating odor. The dissolved aluminum bromide is highly corrosive and reacts with moisture. |
| Flash Point | Not applicable (aqueous solution, non-flammable) |
| Boiling Point | Varies with concentration, typically near 100C (212F) for aqueous solutions |
| Vapor Density | Not applicable (liquid solution) |
| Water Reactivity | Already in solution; concentration determines heat release when diluted. Treat as corrosive acidic solution and verify SDS. |

PPE Requirements
Use SCBA for fumes or fire conditions. Wear acid-resistant suit, gloves, boots and face protection where splash or mist exposure is possible.
Isolation & Evacuation
First Actions for a UN 2580 Incident
- Call 911 and the emergency response number shown on shipping papers; confirm the material with ERG, SDS and container markings.
- Keep unauthorized personnel away and establish hot, warm and cold zones before entry.
- Stay upwind, uphill and upstream; avoid low areas where vapors, dust or runoff may collect.
- Avoid breathing vapors, dust, mist or decomposition products and prevent skin or eye contact.
- Do not touch damaged packages or containers unless properly trained and wearing suitable chemical PPE.
- Ventilate confined spaces only after atmospheric monitoring and only with trained, equipped personnel.
- Use ERG Guide 154, SDS, shipping papers and monitoring results for isolation, PPE and fire-control decisions.
