UN 3055 — 2-(2-Aminoethoxy)ethanol
Placard: Corrosive. ERG Guide 154. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
2-(2-Aminoethoxy)ethanol (UN 3055) is a corrosive amine/alcohol liquid. It can burn tissue and may create irritating vapors or smoke when heated.
Hazard overview: The primary hazard is corrosive liquid contact with skin, eyes and respiratory tissue. It is combustible rather than highly flammable, but fire or heating may generate toxic nitrogen-containing smoke.
Response guidance: Isolate the release, avoid mist or liquid contact and keep runoff controlled. Use alcohol-resistant foam, dry chemical or CO2 for fire, with water spray for cooling containers if it will not spread contamination.
Firefighter training notes: Train responders to treat amine/alcohol spills as corrosive liquid incidents and to prevent splash exposure during containment and decon.
Regulatory context: UN 3055 is regulated as a corrosive hazardous material; ERG 154, SDS and shipping papers should guide tactics.
Storage & handling: Store in compatible containers away from acids, oxidizers, heat and ignition sources. Keep containers closed and ventilated.
UN 3055 Quick Details
Common Hazards of UN 3055
- Corrosive liquid; skin and eye contact can cause serious chemical burns.
- Inhalation of mist or vapor may irritate or damage respiratory tissue.
- Combustible liquid; heating can produce irritating or toxic vapors.
- Vapors may be heavier than air and collect in low areas when heated.
- Contact with acids or oxidizers may cause hazardous reactions.
- Runoff can be corrosive and may contaminate waterways.
- Containers may rupture when heated.

PPE Requirements
Use positive-pressure SCBA when vapors, mist or fire gases are possible and chemical-resistant clothing, gloves, boots and face protection for corrosive liquid contact.
Isolation & Evacuation
First Actions for a UN 3055 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; avoid low areas where vapors may collect.
- Avoid breathing vapors, dust, mist or fire gases and prevent skin or eye contact.
- Do not touch damaged containers or spilled material without appropriate PPE.
- Ventilate confined spaces only when trained, equipped and authorized.
- Use ERG guidance, SDS, shipping papers and air monitoring before committing crews.
