UN 3415 Quick Details
UN 3415
Product name: Sodium fluoride, solution
DOT Class: 6
Placard type: Toxic
ERG Guide: 154 (check current ERG)
Initial isolation: ERG 154: Initial isolation 25m in all directions; protective action distance 0.1km daytime, 0.2km nighttime for small spills; increase distances for large spills or fire involvement
Common Hazards of UN 3415
- TOXIC and/or CORROSIVE; inhalation, ingestion or skin contact with material may cause severe injury
- Contact with molten substance may cause severe burns to skin and eyes.
- Avoid any skin contact.
- Fire may produce irritating, corrosive and/or toxic gases.
- Runoff from fire control or dilution water may be corrosive and/or toxic and cause environmental
- Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive
- Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.).
- Corrosives in contact with metals may evolve flammable hydrogen gas.

⚠️ Level B minimum recommended; chemical-resistant gloves, splash goggles, face shield; SCBA for enclosed spaces or spills; acid-resistant protective clothing
Isolation & Evacuation
ERG 154: Initial isolation 25m in all directions; protective action distance 0.1km daytime, 0.2km nighttime for small spills; increase distances for large spills or fire involvement
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 154).
First Actions for a UN 3415 Incident
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Ventilate closed spaces before entering, but only if properly trained and equipped.
- Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
