UN 2764 — Triazine pesticide, liquid, flammable, poisonous
Placard: Flammable. ERG Guide 131. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2764 is Triazine pesticide, liquid, flammable, poisonous, a broad toxic flammable pesticide liquid category assigned to ERG Guide 131. Solvent and active ingredient drive response.
Hazard overview: TOXIC and FLAMMABLE pesticide liquid formulation; inhalation, ingestion or skin absorption may be fatal. Carrier solvent vapors may ignite and form explosive mixtures with air. Vapors are heavier than air and may travel to ignition sources and flash back.
Response guidance: For UN 2764, isolate the area, eliminate ignition sources and use SCBA. Keep vapors out of drains, cool containers from protection and contain toxic runoff using SDS and ERG 131.
Firefighter training notes: Training for UN 2764 should emphasize formulation verification, skin absorption, SCBA use, pesticide decontamination, toxic runoff control and waste handling. Use ERG 131, SDS and local SOP.
Regulatory context: Triazine pesticide, liquid, flammable, poisonous is regulated as a hazardous material for transport and emergency response. Storage, exposure, spill reporting, waste and fire-code duties depend on quantity, concentration and jurisdiction; verify shipping papers, SDS and local authority requirements.
Storage & handling: Triazine pesticide, liquid, flammable, poisonous should be stored in a secure pesticide/toxic-material area with ventilation, secondary containment, restricted access and segregation from food, feed, drains, ignition sources and incompatibles.
UN 2764 Quick Details
Common Hazards of UN 2764
- TOXIC and FLAMMABLE pesticide liquid formulation; inhalation, ingestion or skin absorption may be fatal.
- Carrier solvent vapors may ignite and form explosive mixtures with air.
- Vapors are heavier than air and may travel to ignition sources and flash back.
- Liquid can contaminate clothing, soil, drains and waterways.
- Fire may produce highly toxic pesticide decomposition products and irritating/corrosive smoke.
- Runoff may be toxic, persistent and environmentally harmful.
- Exact active ingredient, solvent and concentration must be verified from SDS.
Chemical Identity & Physical Properties
Clear to amber or colored liquid with mild to moderate chemical odor. Liquid at room temperature, typically dissolved in flammable organic solvents.

PPE Requirements
Use positive-pressure SCBA and chemical-resistant protective clothing. Level A may be needed for unknown formulation, heavy vapor/dust or high skin-absorption risk.
Isolation & Evacuation
First Actions for a UN 2764 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.
- Eliminate ignition sources if this can be done safely.
- Avoid breathing vapor, dust, 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 131, SDS, shipping papers and monitoring to set isolation, evacuation and entry decisions.
