UN 2760 — Arsenical pesticide, liquid, flammable, poisonous
Placard: Flammable. ERG Guide 131. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2760 is Arsenical pesticide, liquid, flammable, poisonous, a broad toxic flammable arsenical pesticide liquid category assigned to ERG Guide 131. Vapor ignition and arsenic runoff are key.
Hazard overview: TOXIC and FLAMMABLE arsenic-containing 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 2760, 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 2760 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: Arsenical 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: Arsenical 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 2760 Quick Details
Common Hazards of UN 2760
- TOXIC and FLAMMABLE arsenic-containing 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
Flammable liquid containing arsenic compounds, typically clear to amber colored with a solvent-like or chemical odor. Physical properties vary depending on specific formulation and carrier solvent.
| Also known as | arsenical pesticide solutionarsenic-based pesticide liquidflammable arsenic pesticideliquid arsenic agricultural chemical |
| Appearance | Flammable liquid containing arsenic compounds, typically clear to amber colored with a solvent-like or chemical odor. Physical properties vary depending on specific formulation and carrier solvent. |
| Flash Point | Below 23°C (73°F) - Class 3 flammable liquid |
| Boiling Point | Varies by formulation, typically 60-150°C (140-302°F) depending on solvent base |
| Vapor Density | Heavier than air (typically >1), vapors accumulate in low areas |
| Water Reactivity | No violent reaction with water, but may hydrolyze releasing toxic arsenic compounds; spills should not be flushed to waterways |

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 2760 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.
