UN 3460 — N-Ethylbenzyltoluidines, solid
Placard: Toxic. ERG Guide 153. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 3460 is N-Ethylbenzyltoluidines, solid, a toxic aromatic amine solid assigned to ERG Guide 153. Skin contact and exact isomer/formulation require review.
Hazard overview: TOXIC aromatic amine solid; inhalation, ingestion or skin absorption may cause severe injury. Skin contact and contaminated clothing are major exposure concerns. Combustible solid: may burn but does not ignite readily; molten material can increase exposure risk.
Response guidance: For UN 3460, isolate the area, avoid skin contact and use SCBA where vapor, dust, mist or fire is present. Contain runoff and verify controls with SDS/ERG 153.
Firefighter training notes: Training for UN 3460 should emphasize exposure routes, SCBA use, vapor/dust monitoring, decontamination, runoff containment and SDS verification. Use ERG 153, SDS and local SOP.
Regulatory context: N-Ethylbenzyltoluidines, solid is regulated as a hazardous material for transport and emergency response. Storage, reporting, exposure, waste and incident-notification duties depend on quantity, concentration, formulation and jurisdiction; verify shipping papers, SDS and authority guidance.
Storage & handling: N-Ethylbenzyltoluidines, solid should be stored in tightly closed compatible containers with ventilation, secondary containment, restricted access and SDS-based segregation from incompatible materials.
UN 3460 Quick Details
Common Hazards of UN 3460
- TOXIC aromatic amine solid; inhalation, ingestion or skin absorption may cause severe injury.
- Skin contact and contaminated clothing are major exposure concerns.
- Combustible solid: may burn but does not ignite readily; molten material can increase exposure risk.
- Dust or heated vapors may irritate eyes, skin and respiratory tract.
- Fire may produce nitrogen oxides and toxic aromatic amine smoke.
- Runoff may carry toxic amine contamination.
- Exact isomer/formulation should be verified from SDS.
Chemical Identity & Physical Properties
Solid aromatic amine compound, typically appearing as a tan to brown crystalline or waxy solid at room temperature. May have a faint amine-like odor.

PPE Requirements
Use positive-pressure SCBA where vapor, dust, mist, smoke or fire is present. Wear chemical-resistant gloves, boots, eye/face protection and protective clothing.
Isolation & Evacuation
First Actions for a UN 3460 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, mist, smoke or fumes and avoid skin or eye contact.
- Do not touch damaged containers, equipment 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.
