UN 2771 — Thiocarbamate pesticide, solid, poisonous

Placard: Toxic. ERG Guide 151. 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.

UN 2771 is Thiocarbamate pesticide, solid, poisonous, a broad toxic pesticide solid category assigned to ERG Guide 151. Active ingredient and formulation must be verified.

Hazard overview: TOXIC pesticide solid; inhalation of dust, ingestion or skin absorption may cause severe poisoning. Dust can contaminate clothing, tools, soil and runoff. Most formulations are combustible or non-combustible depending on active ingredient and carrier; verify SDS.

Response guidance: For UN 2771, isolate the area, avoid skin contact and use SCBA where dust, vapor, mist or fire is present. Prevent contaminated runoff and verify exact formulation with SDS and ERG 151.

Firefighter training notes: Training for UN 2771 should emphasize formulation verification, skin absorption, SCBA use, pesticide decontamination, toxic runoff control and waste handling. Use ERG 151, SDS and local SOP.

Regulatory context: Thiocarbamate pesticide, solid, poisonous is regulated as a hazardous material for transport and emergency response. Storage, exposure, spill reporting, waste and fire-code duties depend on quantity, concentration and jurisdiction; verify shipping papers, SDS and local authority requirements.

Storage & handling: Thiocarbamate pesticide, solid, poisonous should be stored in a secure pesticide/toxic-material area with ventilation, secondary containment, restricted access and segregation from food, feed, drains, ignition sources and incompatibles.

UN 2771 Quick Details

UN 2771
Product name: Thiocarbamate pesticide, solid, poisonous
DOT Class: 6
Placard type: Toxic
ERG Guide: 151 (check current ERG)
Initial isolation: ERG 151: isolate spill 25-50m all directions; if fire isolate 800m initially, evacuate downwind areas

Common Hazards of UN 2771

  • TOXIC pesticide solid; inhalation of dust, ingestion or skin absorption may cause severe poisoning.
  • Dust can contaminate clothing, tools, soil and runoff.
  • Most formulations are combustible or non-combustible depending on active ingredient and carrier; verify SDS.
  • Fire may produce highly toxic pesticide decomposition products and irritating smoke.
  • Runoff may be toxic, persistent and harmful to waterways.
  • Avoid dust generation and all unprotected skin contact.
  • Exact active ingredient, concentration and formulation must be verified from shipping papers and SDS.

Chemical Identity & Physical Properties

Solid material, typically white to tan crystalline powder or granules, may have slight sulfurous or chemical odor, stable at room temperature.

Also known asThiocarbamate pesticidesDithiocarbamate pesticidesCarbamate herbicidesEPTC-type pesticides
AppearanceSolid material, typically white to tan crystalline powder or granules, may have slight sulfurous or chemical odor, stable at room temperature.
Flash PointVaries by formulation, typically >100C (212F) for solid pesticide products
Boiling PointNot applicable (solid decomposes before boiling)
Vapor DensityNot applicable (solid)
Water ReactivityGenerally stable in water, though some formulations may hydrolyze slowly
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.

Fireground Response Guidance — UN 2771

Extinguishing Media

Use dry chemical, CO2, foam or water spray as compatible with fire size. Cool containers from protection and contain toxic runoff.

PPE Requirements

⚠️ Level B minimum with SCBA; chemical-resistant suit required; avoid all skin contact due to high dermal toxicity

Use positive-pressure SCBA and chemical-resistant protective clothing. Level A may be needed for unknown formulation, heavy vapor/dust or high skin-absorption risk.

Isolation & Evacuation

ERG 151: isolate spill 25-50m all directions; if fire isolate 800m initially, evacuate downwind areas
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 151).

First Actions for a UN 2771 Incident

  • Call 911 and the emergency response number on the shipping paper, if available.
  • Keep unauthorized personnel away and establish incident command.
  • Stay upwind, uphill and upstream.
  • Avoid breathing vapor, dust, mist, smoke or fumes and avoid skin or eye contact.
  • Do not touch damaged containers or spilled material without proper training and PPE.
  • Prevent contaminated liquid, dust, runoff and decontamination waste from spreading.
  • Ventilate confined spaces only after monitoring and only if properly trained and equipped.
  • Use ERG Guide 151, SDS, shipping papers and monitoring to set isolation, evacuation and entry decisions.
