UN 2526 — Furfurylamine
Placard: Flammable. ERG Guide 132. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2526 is Furfurylamine, a flammable corrosive amine assigned to ERG Guide 132. Vapor flashback, alkaline burns and runoff are key concerns.
Hazard overview: FLAMMABLE and CORROSIVE amine liquid; vapors may ignite and form explosive mixtures with air. Liquid and vapor can burn eyes, skin and respiratory tissue. Vapors are heavier than air and may travel to ignition sources and flash back.
Response guidance: For UN 2526, isolate the area, eliminate ignition sources, keep vapors out of drains and use SCBA in vapor or fire conditions. Select foam, dry chemical or CO2 using SDS and ERG 132.
Firefighter training notes: Training for UN 2526 should emphasize vapor travel, sewer flashback, foam selection, ignition control, container cooling, SCBA use and runoff containment. Use ERG 132, SDS and local SOP.
Regulatory context: Furfurylamine is regulated as a hazardous material for transport and emergency response. Storage, exposure, spill reporting, waste and fire-code duties depend on quantity, concentration and jurisdiction; verify shipping papers, SDS and local authority requirements.
Storage & handling: Furfurylamine should be stored in approved compatible containers with ventilation, secondary containment and separation from heat, ignition sources, oxidizers and incompatible materials according to SDS.

PPE Requirements
Use positive-pressure SCBA for vapor, fire or confined-space exposure. Wear chemical-resistant gloves, eye/face protection and flame-resistant protection as appropriate.
Isolation & Evacuation
First Actions for a UN 2526 Incident
- Call 911 and the emergency response number on the shipping paper, if available.
- Keep unauthorized personnel away and establish incident command.
- Stay upwind, uphill and upstream.
- Eliminate ignition sources if this can be done safely.
- Avoid breathing vapor, dust, mist, smoke or fumes and avoid skin or eye contact.
- Do not touch damaged containers or spilled material without proper training and PPE.
- Ventilate confined spaces only after monitoring and only if properly trained and equipped.
- Use ERG Guide 132, SDS, shipping papers and monitoring to set isolation, evacuation and entry decisions.
