UN 1169 — Extracts, aromatic, liquid
Placard: Flammable. ERG Guide 127. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 1169 is Extracts, aromatic, liquid, a Class 3 flammable aromatic hydrocarbon entry assigned to ERG Guide 127. It can produce heavy vapors, flashback hazards and toxic smoke during fire.
Hazard overview: UN 1169 presents flammable vapor, flashback and aromatic hydrocarbon exposure hazards. Vapors may collect in low areas, spilled liquid may float on water, and fire can produce irritating or toxic smoke.
Response guidance: For a UN 1169 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 Class B fire-control agents from a protected position.
Firefighter training notes: Training for UN 1169 should emphasize flammable liquid vapor travel, flashback, sewer vapor explosion risk, foam compatibility, container cooling and atmospheric monitoring. Common errors include standing downwind, allowing runoff into drains and ignoring low-area vapor collection. Use ERG 127, SDS and local SOP.
Regulatory context: Extracts, aromatic, liquid 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: Extracts, aromatic, liquid 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 1169 Quick Details
Common Hazards of UN 1169
- FLAMMABLE aromatic hydrocarbon liquid; vapors may ignite and form explosive mixtures with air.
- Vapors are heavier than air and may collect in low, confined or sewer areas.
- Liquid may float on water and spread fire across surfaces.
- Vapor exposure may cause dizziness, headache or respiratory irritation.
- Fire may produce irritating or toxic smoke.
- Runoff to sewer may create fire, explosion or environmental hazards.
- Containers 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 using SDS, product concentration and incident command.
Isolation & Evacuation
First Actions for a UN 1169 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.
