UN 2757 — Carbamate pesticide, solid, poisonous
Placard: Toxic. ERG Guide 151. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2757 is Carbamate 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 2757, 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 2757 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: Carbamate 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: Carbamate 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 2757 Quick Details
Common Hazards of UN 2757
- 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
Typically appears as white to tan crystalline powder or granular solid with mild to no odor at room temperature. Various carbamate pesticides exist under this classification.

| Appearance | Typically appears as white to tan crystalline powder or granular solid with mild to no odor at room temperature. Various carbamate pesticides exist under this classification. |
| Flash Point | Varies by specific compound; typically >100C (>212F) for most carbamate solids |
| Boiling Point | Not applicable (decomposes before boiling); most carbamates decompose at 150-200C |
| Vapor Density | Not applicable (solid at room temperature) |
| Water Reactivity | Generally stable in water but slowly hydrolyzes; avoid strong acids or bases which accelerate decomposition |

PPE Requirements
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
First Actions for a UN 2757 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.
