UN 1286 — Rosin oil
Placard: Flammable. ERG Guide 127. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 1286 is Rosin oil, a Class 3 flammable hydrocarbon liquid assigned to ERG Guide 127. It can produce heavy vapors, flashback hazards and floating fuel fires if spilled near water or drains.
Hazard overview: UN 1286 presents hydrocarbon vapor, surface-spread fire and environmental runoff hazards. Vapors may collect in low or sewer areas, and floating liquid can carry fire across water surfaces.
Response guidance: For a UN 1286 incident, responders should confirm the product using shipping papers, container markings, SDS and ERG Guide 127. Establish incident command, isolate the area, stay upwind and uphill, remove ignition sources when safe, keep vapors or runoff out of sewers and use compatible fire-control agents from a protected position.
Firefighter training notes: Training for UN 1286 should emphasize hydrocarbon vapor travel, flashback, surface-spreading fuel, sewer vapor explosion risk, foam use and runoff control. Use ERG 127, SDS and local SOP.
Regulatory context: Rosin oil is regulated as a hazardous material for transportation and emergency response purposes. Transportation, workplace exposure, spill reporting, waste handling, storage and environmental requirements may vary by formulation, quantity and jurisdiction. Verify current requirements through shipping papers, SDS, facility documents and applicable DOT, OSHA, EPA, NFPA, state or local authority guidance.
Storage & handling: Rosin oil should be stored in tightly closed compatible containers in a cool, dry, well-ventilated flammable-liquid storage area. Keep away from heat, sparks, open flames, oxidizers and incompatible materials, with bonding/grounding, secondary containment and drain protection where required.
UN 1286 Quick Details
Common Hazards of UN 1286
- FLAMMABLE hydrocarbon liquid; may be ignited by heat, sparks or flames.
- Vapors may form explosive mixtures with air, especially when heated or aerosolized.
- Vapors are heavier than air and may collect in low, confined or sewer areas.
- Liquid floats on water and may spread fire across surfaces.
- Runoff to sewer or waterways may create fire and environmental hazards.
- Fire may produce irritating or toxic smoke.
- Containers or tanks may rupture or explode when heated.

PPE Requirements
Use positive-pressure SCBA for fire, heavy vapor or confined-space exposure. Chemical-resistant gloves, splash protection and protective clothing should be selected from SDS; avoid skin contact with liquid and contaminated runoff.
Isolation & Evacuation
First Actions for a UN 1286 Incident
- CALL 911. Then call the emergency response telephone number on the shipping paper, if available.
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Eliminate ignition sources if it is safe to do so.
- Do not touch or walk through spilled liquid unless properly trained and wearing appropriate protective equipment.
- Ventilate closed spaces before entering, but only if properly trained, equipped and authorized by incident command.
- Isolate the spill or leak area for at least 50 meters (150 feet) in all directions.
- For large spills, fire involvement or strong vapor movement, expand isolation and consider downwind evacuation based on monitoring and incident command.
- Use ERG Guide 127, shipping papers, SDS and local SOP for protective actions and entry decisions.
