Common Hazards of UN 1507
- These substances will accelerate burning when involved in a fire.
- Some may decompose explosively when heated or involved in a fire.
- May explode from heat or contamination.
- Some will react explosively with hydrocarbons (fuels).
- May ignite combustibles (wood, paper, oil, clothing, etc.).
- Containers may explode when heated.
- Runoff may create fire or explosion hazard.
- Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or

Fireground Response Guidance — UN 1507
Extinguishing Media
Water spray or fog acceptable; avoid organic materials and combustibles near oxidizer
PPE Requirements
⚠️ Level C minimum for spills; Level B with SCBA if fire or decomposition occurring; dust-proof chemical goggles and nitrile gloves
Isolation & Evacuation
ERG 140: isolate spill 50m all directions; if fire or large spill isolate 800m initially, protect personnel downwind
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 140).
First Actions for a UN 1507 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).
