Fireground Response Guidance — UN 1448
Extinguishing Media
Dry chemical, sand, or CO2 preferred; avoid organic materials or combustibles near oxidizer
PPE Requirements
⚠️ Level B minimum with SCBA; full chemical-resistant suit recommended due to oxidizer and potential permanganate exposure
Isolation & Evacuation
ERG 141: isolate spill area at least 25-50m in all directions; if tank/rail car involved in fire, isolate 800m all directions
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 141).
First Actions for a UN 1448 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).
