UN 2761 — Organochlorine pesticide, solid, poisonous
Placard: Toxic. ERG Guide 151. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2761 is Organochlorine pesticide, solid, poisonous, a broad toxic organochlorine pesticide solid category assigned to ERG Guide 151. Persistent contamination and toxic smoke are key.
Hazard overview: TOXIC organochlorine 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 2761, 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 2761 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: Organochlorine 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: Organochlorine 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.

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 2761 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.
