UN 2629 — Sodium fluoroacetate
Placard: Toxic. ERG Guide 151. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2629 is Sodium fluoroacetate, a highly toxic fluoroacetate salt assigned to ERG Guide 151. Dust, solution and skin contact are major response concerns.
Hazard overview: HIGHLY TOXIC fluoroacetate salt; ingestion, inhalation of dust or skin contact may cause severe or fatal poisoning. Dust or solution can contaminate clothing, tools, soil and runoff. Non-combustible solid, but heating or fire may produce toxic and corrosive fluoride-containing fumes.
Response guidance: For UN 2629, isolate the area, avoid skin contact and use SCBA where dust, vapor, mist or fire is present. Prevent spread of contaminated runoff, cool containers from protection and verify controls with SDS and ERG 151.
Firefighter training notes: Training for UN 2629 should emphasize toxic exposure routes, skin absorption, SCBA use, dust/vapor control, decontamination, runoff containment and SDS verification. Use ERG 151, SDS and local SOP.
Regulatory context: Sodium fluoroacetate 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: Sodium fluoroacetate should be stored in tightly closed labeled containers in a secure toxic-material area with dust control, secondary containment, restricted access and SDS-based segregation.
UN 2629 Quick Details
Common Hazards of UN 2629
- HIGHLY TOXIC fluoroacetate salt; ingestion, inhalation of dust or skin contact may cause severe or fatal poisoning.
- Dust or solution can contaminate clothing, tools, soil and runoff.
- Non-combustible solid, but heating or fire may produce toxic and corrosive fluoride-containing fumes.

PPE Requirements
Use positive-pressure SCBA and full chemical protective clothing. Level A may be needed for heavy vapor, dust, splash risk or unknown concentrations; prevent all skin contact.
Isolation & Evacuation
First Actions for a UN 2629 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 dust, liquid, 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.
