Common Hazards of UN 1710
- Toxic by ingestion.
- Vapors may cause dizziness or asphyxiation, especially when in closed or confined areas.
- Exposure in an enclosed area may be very harmful.
- Contact may irritate or burn skin and eyes.
- Fire may produce irritating and/or toxic gases.
- Runoff from fire control or dilution water may cause environmental contamination.
- Some of these materials may burn, but none ignite readily.
- Most vapors are heavier than air.

Fireground Response Guidance — UN 1710
Extinguishing Media
Alcohol-resistant foam, CO2, dry chemical, water spray for cooling
PPE Requirements
⚠️ Level B minimum with SCBA; butyl rubber or nitrile gloves; chemical-resistant suit for liquid contact
Isolation & Evacuation
ERG 160: isolate spill/leak area immediately for at least 50m in all directions; in case of large spill, consider initial downwind evacuation for at least 300m
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 160).
First Actions for a UN 1710 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.
- Many gases are heavier than air and will spread along the ground and collect in low or confined areas
- Ventilate closed spaces before entering, but only if properly trained and equipped.
- Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
- Consider initial downwind evacuation for at least 100 meters (330 feet).
