UN 3019 — Organotin pesticide, liquid, poisonous, flammable
Placard: Toxic. ERG Guide 131. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
Organotin pesticide, liquid, poisonous, flammable is a liquid pesticide formulation assigned to UN 3019. 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: Organotin pesticides may cause serious systemic toxicity and persistent contamination; avoid all contact with liquid and vapors.
Response guidance: For UN 3019, 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 organotin pesticide formulation from shipping papers and SDS before close approach.
Firefighter training notes: Train responders to treat UN 3019 as a toxic pesticide release, verify the exact product, control runoff and avoid skin contact during rescue, containment and decon.
Regulatory context: UN 3019 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 3019 away from food, feed, drains, ignition sources where applicable and incompatible chemicals. Keep containers closed, labeled and protected from heat or physical damage.
UN 3019 Quick Details
Common Hazards of UN 3019
- Organotin pesticide 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
Liquid, color and odor vary depending on specific organotin compound and formulation. Typically pale yellow to amber liquid with mild to pungent organic odor. Product-specific appearance and odor should not be used as the only identification method.

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 3019 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.
