UN 2015 Quick Details
UN 2015
Product name: Hydrogen peroxide, aqueous solution, stabilized, with more than 60% hydrogen peroxide
DOT Class: 5
Placard type: Oxidizer
ERG Guide: 143 (check current ERG)
Initial isolation: ERG 143: isolate spill 100m all directions; if tank/rail car involved in fire, isolate 800m all directions and evacuate 1600m downwind
Common Hazards of UN 2015
- May explode from friction, heat or contamination.
- These substances will accelerate burning when involved in a fire.
- May ignite combustibles (wood, paper, oil, clothing, etc.).
- Some will react explosively with hydrocarbons (fuels).
- Containers may explode when heated.
- Runoff may create fire or explosion hazard.
- TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe
- Fire may produce irritating and/or toxic gases.
Chemical Identity & Physical Properties
| Also known as | Hydrogen dioxidePeroxideHydroperoxideAlboneOxydol |
| CAS Number | 7722-84-1 |
| Appearance | Colorless to pale blue liquid with a slightly sharp odor. Strong oxidizer. Concentrated solutions (>60%) are highly reactive and unstable. |
| Flash Point | Not applicable (oxidizer) |
| Boiling Point | 150C (302F) at 100% concentration |
| Vapor Density | 1.2 (heavier than air) |
| Water Reactivity | Miscible with water; dilution generates heat and can cause violent decomposition if contaminated |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 2015
Extinguishing Media
Water spray for cooling only; no foam, no dry chemical; use water from distance
PPE Requirements
⚠️ Level A required for concentrated solutions; full face SCBA; chemical-resistant suit; avoid all organic materials
Isolation & Evacuation
ERG 143: isolate spill 100m all directions; if tank/rail car involved in fire, isolate 800m all directions and evacuate 1600m downwind
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 143).
First Actions for a UN 2015 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
