UN 2946 — 2-Amino-5-diethylaminopentane
Placard: Toxic. ERG Guide 153. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2946 is 2-Amino-5-diethylaminopentane, a toxic amine liquid assigned to ERG Guide 153. Skin exposure, alkaline runoff and toxic smoke require control.
Hazard overview: TOXIC amine liquid; inhalation, ingestion or skin absorption may cause severe injury. Combustible liquid; heated vapors may form ignitable mixtures with air. Liquid and vapor may burn or irritate eyes, skin and respiratory tissue.
Response guidance: For UN 2946, isolate the area, avoid skin contact and use SCBA where dust, vapor, mist or fire is present. Contain runoff and verify controls with SDS and ERG 153.
Firefighter training notes: Training for UN 2946 should emphasize exposure routes, SCBA use, vapor/dust monitoring, decontamination, runoff containment and SDS verification. Use ERG 153, SDS and local SOP.
Regulatory context: 2-Amino-5-diethylaminopentane is regulated as a hazardous material for transport and emergency response. Storage, reporting, exposure, waste and incident-notification duties depend on quantity, formulation and jurisdiction; verify shipping papers, SDS and authority guidance.
Storage & handling: 2-Amino-5-diethylaminopentane should be stored in tightly closed compatible containers with ventilation, secondary containment, restricted access and SDS-based segregation from incompatible materials.

PPE Requirements
Use positive-pressure SCBA for vapor, dust, mist, fire or confined-space exposure. Wear chemical-resistant gloves, boots, eye/face protection and protective clothing.
Isolation & Evacuation
First Actions for a UN 2946 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 breathing vapor, dust, gas, mist, smoke or fumes and avoid skin or eye contact.
- Do not touch damaged containers or spilled material without proper training and PPE.
- Prevent contaminated liquid, dust, runoff and decontamination waste from spreading.
- Ventilate confined spaces only after monitoring and only if properly trained and equipped.
- Use ERG Guide 153, SDS, shipping papers and monitoring to set isolation, evacuation and entry decisions.
