UN 3021 — Pesticide, liquid, flammable, toxic, n.o.s.
Placard: Flammable. ERG Guide 131. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
Pesticide, liquid, flammable, toxic, n.o.s. is a liquid pesticide formulation assigned to UN 3021. It should be treated as a toxic pesticide product until the active ingredient, carrier solvent and concentration are confirmed from shipping papers and the SDS.
Hazard overview: The main concern with UN 3021 is toxic exposure from the pesticide formulation. Dermal absorption, inhalation of vapors or dust, ingestion, contaminated runoff and toxic fire gases are the response priorities.
Response guidance: For UN 3021, isolate the release, remove ignition sources, stay upwind and keep runoff out of drains. Use alcohol-resistant foam, dry chemical or CO2 for fire control, with water spray only for cooling exposed containers when safe. Confirm the exact pesticide, liquid, flammable, toxic, n.o.s. formulation from shipping papers and SDS before close approach.
Firefighter training notes: Train responders to treat UN 3021 as a toxic pesticide release, verify the exact product, control runoff and avoid skin contact during rescue, containment and decon.
Regulatory context: UN 3021 is regulated for transport as a hazardous pesticide entry. Product labels, shipping papers, SDS and local environmental reporting rules should guide final actions.
Storage & handling: Store UN 3021 away from food, feed, drains, ignition sources where applicable and incompatible chemicals. Keep containers closed, labeled and protected from heat or physical damage.
UN 3021 Quick Details
Common Hazards of UN 3021
- Pesticide, liquid, flammable, toxic, n.o.s. formulations may be fatal if inhaled, ingested or absorbed through skin.
- Flammable solvent vapors may ignite from heat, sparks, flames or static discharge.
- Vapors may form explosive mixtures with air and travel to ignition sources.
- Skin or eye contact may cause irritation, burns or systemic poisoning.
- Fire can produce toxic pesticide decomposition products and corrosive smoke.
- Runoff can spread contamination and harm waterways.
- Exact toxicity, flash point and solvent behavior depend on the shipped formulation.
Chemical Identity & Physical Properties
Variable appearance depending on formulation; typically colored liquid (amber, yellow, or clear) with mild to pungent chemical odor, liquid at room temperature. Product-specific appearance and odor should not be used as the only identification method.

| Appearance | Variable appearance depending on formulation; typically colored liquid (amber, yellow, or clear) with mild to pungent chemical odor, liquid at room temperature. |
| Flash Point | Below 23C (73F) - varies by formulation |
| Boiling Point | Varies widely by pesticide formulation and solvent system |
| Vapor Density | Typically greater than 1 (heavier than air) |
| Water Reactivity | Generally no violent reaction, but many formulations are immiscible with water |

PPE Requirements
Use positive-pressure SCBA and chemical-resistant protective clothing suitable for pesticide liquids. Gloves, boots and suit material should be selected from the SDS because permeation varies by active ingredient and solvent.
Isolation & Evacuation
First Actions for a UN 3021 Incident
- Call 911 and the emergency response number on the shipping paper, if available.
- Eliminate ignition sources; use non-sparking tools and control traffic around the spill.
- Keep unauthorized personnel away and stay upwind, uphill and upstream.
- Avoid breathing vapors and prevent liquid contact with skin, eyes and clothing.
- Do not enter low areas, drains or confined spaces unless trained and equipped.
- Use ERG 131, SDS, shipping papers and monitoring to set isolation and evacuation distances.
- Contain runoff only if it can be done safely with proper PPE.
