Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 2719
Extinguishing Media
Water spray to keep containers cool; dry chemical or CO2 for surrounding fires; avoid organic materials
PPE Requirements
⚠️ Level B minimum with SCBA; full protective clothing; avoid all contact with skin and eyes due to oxidizer and toxicity
Isolation & Evacuation
ERG 141: Initial isolation 100m in all directions; protective action distance 300m downwind for large spill; 800m if fire involved
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 141).
First Actions for a UN 2719 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
- Consider initial downwind evacuation for at least 100 meters (330 feet).
