UN 3066 — Paint related material (corrosive)
Placard: Corrosive. ERG Guide 153. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 3066 is Paint related material (corrosive), a broad corrosive paint-related material assigned to ERG Guide 153. Exact formulation controls flammability and PPE.
Hazard overview: CORROSIVE paint-related material; formulation may include acids, bases, solvents, resins or pigments. Skin, eye or respiratory contact can cause burns or injury. Some formulations may be combustible or flammable depending on solvent content.
Response guidance: For UN 3066, isolate the area, avoid skin contact and use SCBA where vapor, dust, mist or fire is present. Contain runoff and verify controls with SDS and ERG 153.
Firefighter training notes: Training for UN 3066 should emphasize exposure routes, SCBA use, vapor/dust monitoring, decontamination, runoff containment and SDS/package verification. Use ERG 153, SDS and local SOP.
Regulatory context: Paint related material (corrosive) 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: Paint related material (corrosive) should be stored in tightly closed compatible containers with ventilation, secondary containment, restricted access and SDS-based segregation from incompatible materials.
UN 3066 Quick Details
Common Hazards of UN 3066
- CORROSIVE paint-related material; formulation may include acids, bases, solvents, resins or pigments.
- Skin, eye or respiratory contact can cause burns or injury.
- Some formulations may be combustible or flammable depending on solvent content.
- Dilution or water contact may generate heat or spread corrosive contamination depending on ingredients.
- Fire may produce toxic/corrosive smoke from solvents, resins and corrosive components.
- Runoff may be corrosive, toxic and environmentally harmful.
- Exact formulation must be verified from SDS and shipping papers.
Chemical Identity & Physical Properties
Variable liquid or paste material associated with paint formulations. May be clear to colored liquid with solvent-like or chemical odor. Corrosive properties indicate presence of acids or bases.

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 3066 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.
