UN 2810 — Compounds, tree or weed killing, liquid (toxic)
Placard: Toxic. ERG Guide 153. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
Compounds, tree or weed killing, liquid (toxic) is a broad UN entry for herbicide or arboricide formulations. The active ingredient and carrier solvent must be confirmed before final tactics.
Hazard overview: The shared hazard is toxic exposure by inhalation, ingestion or skin contact. Some formulations also contain combustible solvents, so fire and vapor behavior can vary significantly.
Response guidance: Isolate the area, avoid contact and keep product out of drains and soil. Use foam, dry chemical or carbon dioxide according to the SDS and container label, and collect runoff as contaminated waste.
Firefighter training notes: Train crews to treat UN 2810 as a formulation-dependent pesticide entry. Do not assume the active ingredient; use SDS, labels and shipping papers before selecting foam, decon or waste tactics.
Regulatory context: UN 2810 is a Class 6 toxic shipment. Product labels, pesticide regulations, SDS data and local environmental reporting rules may control cleanup and disposal.
Storage & handling: Store tightly closed in compatible containers away from food, feed, oxidizers and ignition sources when solvent-based. Provide secondary containment and protect from heat.
UN 2810 Quick Details
Common Hazards of UN 2810
- This entry covers variable toxic herbicide or arboricide liquids; exact hazards depend on formulation.
- Inhalation, ingestion or skin absorption may cause serious poisoning.
- Many products contain solvents or carriers that can burn or produce toxic smoke.
- Liquid contact can irritate or injure skin and eyes and contaminate PPE.
- Fire may produce toxic pesticide, solvent and decomposition vapors.
- Runoff can contaminate soil, drains and waterways and may harm aquatic life.
- SDS and shipping papers are essential because active ingredients vary widely.
Chemical Identity & Physical Properties
These products may be clear, amber or dark liquids with mild to pungent odors. Physical properties depend on the active ingredient, solvent base and concentration.
| Also known as | Herbicide liquidTree killing compoundWeed killing compoundPhytocide solutionArboricide liquid |
| Appearance | Various colored liquids (amber, brown, or clear) with odors ranging from mild to pungent, depending on active ingredient formulation. Liquid at room temperature. |
| Flash Point | Varies by formulation; typically 60-93C (140-200F) for petroleum-based carriers, some formulations may be lower |
| Boiling Point | Varies by formulation; typically 100-200C (212-392F) depending on solvent base and active ingredients |
| Vapor Density | Generally heavier than air (>1); typical range 2-4 depending on carrier solvent |
| Water Reactivity | No significant reaction with water; may form emulsions or separate layers depending on formulation |

PPE Requirements
Use SCBA and chemical-resistant clothing for initial spill entry. Gloves, boots and eye protection must be selected for the pesticide formulation and carrier solvent.
Isolation & Evacuation
First Actions for a UN 2810 Incident
- Call 911 and the emergency response number shown on the shipping papers or container documents.
- Keep unauthorized personnel away and establish an isolation perimeter before entry.
- Stay upwind, uphill and upstream; keep responders out of vapors, dusts and runoff.
- Avoid breathing vapors, dust, mist or smoke and avoid skin or eye contact.
- Do not touch damaged containers or spilled material unless properly trained and protected.
- Ventilate confined spaces only when personnel are trained, equipped and monitored.
- Use ERG guidance, SDS, shipping papers and air monitoring to confirm protective actions.
