UN 2815 — N-Aminoethylpiperazine
Placard: Corrosive. ERG Guide 153. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
🚒☣️
⚠️ This page is a quick-reference aid. For real incidents: stage upwind, isolate, deny entry, request Hazmat early, and consult the current ERG + SOP/SOG.
N-Aminoethylpiperazine is a corrosive amine liquid. It can burn tissue, produce irritating vapors and form hot alkaline solutions when mixed with water.
Hazard overview: The main hazards are corrosive contact and inhalation of amine vapors or aerosols. Fire can produce toxic smoke and containers may fail under heat.
Response guidance: Isolate the spill, control ignition sources and keep runoff contained. Use alcohol-resistant foam, carbon dioxide or dry chemical for fire, with water spray only for cooling from a safe distance.

UN 2815
Product name: N-Aminoethylpiperazine
DOT Class: 8
Placard type: Corrosive
ERG Guide: 153 (check current ERG)
Initial isolation: ERG 153: isolate 25-50m initially; if tank/rail car involved in fire, isolate 800m all directions
Common Hazards of UN 2815
- N-aminoethylpiperazine is corrosive to skin and eyes and harmful by inhalation or absorption.
- Vapors and aerosols can irritate the respiratory tract.
- Combustible liquid may burn and produce toxic nitrogen-containing smoke.
- Mixing with water can release heat and form alkaline corrosive solutions.
- Vapors are heavier than air and may collect in low areas.
- Runoff may remain alkaline and contaminated.
- Containers may rupture when heated.
Chemical Identity & Physical Properties
It is usually a clear to pale yellow liquid with an ammonia-like amine odor. It is hygroscopic and miscible with water with heat release.

Fireground Response Guidance — UN 2815
Extinguishing Media
Alcohol-resistant foam, CO2, dry chemical; water spray for cooling only
PPE Requirements
⚠️ Level B minimum; SCBA and chemical-resistant suit required; corrosive to skin and eyes
Use SCBA with chemical-resistant suit, gloves, boots and full face protection. Select glove material for amines and verify with the SDS.
Isolation & Evacuation
ERG 153: isolate 25-50m initially; if tank/rail car involved in fire, isolate 800m all directions
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 153).
First Actions for a UN 2815 Incident
- Call 911 and the emergency response number shown on the shipping papers or container documents.
- Keep unauthorized personnel away and establish an isolation perimeter before entry.
- Stay upwind, uphill and upstream; keep responders out of vapors, dusts and runoff.
- Avoid breathing vapors, dust, mist or smoke and avoid skin or eye contact.
- Do not touch damaged containers or spilled material unless properly trained and protected.
- Ventilate confined spaces only when personnel are trained, equipped and monitored.
- Use ERG guidance, SDS, shipping papers and air monitoring to confirm protective actions.
