UN 1760 — Compounds, tree or weed killing, liquid (corrosive)
Placard: Corrosive. ERG Guide 154. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 1760 is Compounds, tree or weed killing, liquid (corrosive), a corrosive liquid herbicide/pesticide formulation assigned to ERG Guide 154. The active ingredient and solvent package control toxicity, flammability and runoff risk.
Hazard overview: UN 1760 presents corrosive liquid, toxic formulation and environmental runoff hazards. Some products may be solvent-based and combustible, so responders should verify the SDS before choosing foam, water or dry chemical.
Response guidance: For a UN 1760 incident, responders should verify the product with shipping papers, package markings, SDS and ERG Guide 154. Establish incident command, isolate the area, stay upwind, prevent incompatible contact, control runoff and choose entry or fire-control actions based on monitoring, SDS and local SOP.
Firefighter training notes: Training for UN 1760 should emphasize formulation-dependent pesticide/herbicide hazards, corrosive burns, vapor/mist control, runoff protection and SDS-driven PPE. Use ERG 154, SDS and local SOP.
Regulatory context: Compounds, tree or weed killing, liquid (corrosive) is regulated as a hazardous material for transportation and emergency response purposes. Transportation, workplace exposure, spill reporting, pesticide/waste handling where applicable, storage and environmental requirements may vary by formulation, concentration, 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: Compounds, tree or weed killing, liquid (corrosive) should be stored in compatible corrosion-resistant containers with secondary containment, away from incompatible chemicals, heat, ignition sources if solvent-based and unauthorized access. Prevent leaks and environmental runoff according to SDS.
UN 1760 Quick Details
Common Hazards of UN 1760
- CORROSIVE liquid formulation; inhalation, ingestion or skin/eye contact may cause severe injury.
- May also contain toxic herbicide or pesticide ingredients depending on formulation.
- Vapors or spray mist may irritate eyes, skin and respiratory tissue.
- Some solvent-based products may be combustible; verify flash point from SDS.
- Fire may produce irritating, corrosive and/or toxic gases.
- Runoff may be corrosive, toxic and environmentally harmful.
- Exact hazards vary by active ingredient, solvent and concentration.
Chemical Identity & Physical Properties
Varies widely - typically colored liquid (amber, brown, or clear) with chemical or solvent odor. Corrosive nature causes immediate tissue damage on contact.

| Appearance | Varies widely - typically colored liquid (amber, brown, or clear) with chemical or solvent odor. Corrosive nature causes immediate tissue damage on contact. |
| Flash Point | Varies by formulation - typically 23-60C (73-140F) for organic solvent-based products |
| Boiling Point | Varies by formulation - typically 100-200C (212-392F) depending on solvent base |
| Vapor Density | Varies - typically 3-5 (heavier than air) for organic solvent formulations |
| Water Reactivity | May react with water generating heat; dilution may be hazardous due to corrosivity |

PPE Requirements
Use positive-pressure SCBA for vapor, mist, spray or fire exposure. Chemical-resistant gloves, boots, eye/face protection and suit material should be selected from the product SDS because formulations vary.
Isolation & Evacuation
First Actions for a UN 1760 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.
- Avoid breathing vapors, fumes, dust, mist or spray and avoid skin or eye contact.
- Do not touch or walk through spilled material unless properly trained and wearing appropriate protective equipment.
- Prevent product, dust, solution or runoff from reaching drains and waterways where practical.
- Ventilate closed spaces before entering, but only if properly trained, equipped, monitored and authorized by incident command.
- Isolate the spill or leak area and expand the perimeter if vapor, dust, fire involvement, water reaction or unknown concentration is present.
- Use ERG Guide 154, shipping papers, SDS, air monitoring and incident command for protective actions.
