UN 2772 — Thiocarbamate pesticide, liquid, flammable, poisonous

Placard: Flammable. ERG Guide 131. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.

🚒☣️
⚠️ Verification required: Broad or variable material category; verify exact product, SDS and shipping papers.
⚠️ This page is a quick-reference aid. For real incidents: stage upwind, isolate, deny entry, request Hazmat early, and consult the current ERG + SOP/SOG.

Thiocarbamate pesticide, liquid, flammable, poisonous is a variable pesticide formulation shipped as a toxic flammable liquid. The active ingredient and solvent system must be verified before responders choose final tactics.

Hazard overview: Thiocarbamate pesticide may be highly toxic by inhalation, ingestion or skin absorption. Liquid or dust contact can irritate or burn skin and eyes depending on the formulation. Fire or heating may produce irritating, toxic and corrosive decomposition products.

Response guidance: For a Thiocarbamate pesticide, liquid, flammable, poisonous release, isolate the area, remove ignition sources if present, and keep runoff out of drains. Responders should use SCBA with chemical-resistant clothing and base tactics on SDS, shipping papers and monitoring.

Firefighter training notes: Train responders to identify the UN number, product name, placard, container type and exposure route before committing personnel to the hot zone.

Regulatory context: Use the proper DOT shipping description, ERG guide, SDS and site-specific response plan; do not substitute this summary for regulatory compliance.

Storage & handling: Store away from heat, sparks, oxidizers, drains and food/feed materials; segregate by pesticide formulation and SDS requirements.

Common Hazards of UN 2772

  • Thiocarbamate pesticide may be highly toxic by inhalation, ingestion or skin absorption.
  • Liquid or dust contact can irritate or burn skin and eyes depending on the formulation.
  • Fire or heating may produce irritating, toxic and corrosive decomposition products.
  • Runoff, wash water and contaminated absorbent can carry pesticide into drains or waterways.
  • Exact active ingredient, solvent carrier and concentration must be verified from SDS and shipping papers.
  • Flammable solvent vapors may form explosive mixtures with air.
  • Vapors can travel to ignition sources and flash back, especially in low or confined areas.
  • Containers may rupture or explode when heated.

Chemical Identity & Physical Properties

Liquid pesticide formulations, color varies by product (often amber to dark brown), may have mild to pungent odor depending on formulation and solvents used.

AppearanceLiquid pesticide formulations, color varies by product (often amber to dark brown), may have mild to pungent odor depending on formulation and solvents used.
Flash PointTypically 23-60°C (73-140°F), varies by formulation and solvent system
Boiling PointVaries widely by formulation, typically 150-300°C (302-572°F)
Vapor DensityGreater than 1 (heavier than air), typically 3-6 times air density
Water ReactivityNo violent water reaction is expected, but water can spread toxic pesticide contamination; verify formulation-specific SDS.
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.

Fireground Response Guidance — UN 2772

Extinguishing Media

Alcohol-resistant foam, dry chemical or CO2 are preferred for flammable solvent formulations; water spray may cool containers.

PPE Requirements

⚠️ SCBA with Level A or B chemical protection may be required; avoid all skin contact and use product-specific pesticide decon.

Level B minimum with SCBA required; full chemical-resistant suit, gloves, and boots; avoid all skin contact due to dermal toxicity

Isolation & Evacuation

Use ERG Guide 131 initial isolation, then adjust with SDS, shipping papers, wind, monitoring and amount released.
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 131).

First Actions for a UN 2772 Incident

  • Call 911 and the emergency response number shown on the shipping papers.
  • Keep unauthorized personnel away and establish an initial isolation perimeter.
  • Stay upwind, uphill and upstream; avoid low areas where vapors or runoff may collect.
  • Avoid breathing vapors, dust, mist or smoke and prevent skin and eye contact.
  • Do not touch damaged packages, leaking containers or spilled material without appropriate PPE.
  • Eliminate ignition sources; stop traffic, engines, smoking and open flames if it can be done safely.
  • Ventilate confined spaces only when responders are trained, equipped and monitoring conditions.
  • Use ERG, SDS, shipping papers and air monitoring to set final isolation, evacuation and decon actions.

UN 2772 covers Thiocarbamate pesticide, liquid, flammable, poisonous. Use the shipping papers and SDS to confirm the exact product before choosing tactics.

Yes. Exposure may be harmful or fatal by inhalation, ingestion or skin absorption, depending on concentration and formulation.

Yes. Keep ignition sources away because vapors can ignite and flash back from low or confined areas.

No violent water reaction is expected, but water can spread contamination and does not reduce toxicity.

Alcohol-resistant AFFF foam, CO2, dry chemical powder; regular foam may not be effective on polar solvents

Use SCBA and chemical-resistant protective clothing. Level A or B may be needed when vapors, splash risk or product identity is uncertain.
