UN 2015 — Hydrogen peroxide, aqueous solution, stabilized, with more than 60% hydrogen peroxide
Placard: Oxidizer. ERG Guide 143. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 2015 is Hydrogen peroxide, aqueous solution, stabilized, with more than 60% hydrogen peroxide, a concentrated oxidizing hydrogen peroxide solution assigned to ERG Guide 143. It can decompose violently from heat, friction or contamination.
Hazard overview: STRONG OXIDIZER; concentrated hydrogen peroxide may explode from heat, friction or contamination. Accelerates burning and may ignite combustibles such as wood, paper, oil or clothing. Can react violently with fuels, organics, metals, reducing agents or incompatible absorbents.
Response guidance: For a UN 2015 incident, verify the product with shipping papers, container markings, SDS and ERG Guide 143. Establish incident command, isolate the area, stay upwind, prevent incompatible contact, control runoff or dust spread and base entry/fire-control actions on monitoring and local SOP.
Firefighter training notes: Training for UN 2015 should emphasize oxidizer contamination control, organic/fuel incompatibility, decomposition pressure, compatible PPE, water application limits and runoff control. Use ERG 143, SDS and local SOP.
Regulatory context: Hydrogen peroxide, aqueous solution, stabilized, with more than 60% hydrogen peroxide is regulated as a hazardous material for transportation and emergency response purposes. Storage, workplace exposure, emergency planning, spill reporting, waste handling and environmental requirements vary by exact product, concentration, quantity and jurisdiction. Verify current requirements through shipping papers, SDS, container markings and applicable DOT, OSHA, EPA, NFPA, state or local authority guidance.
Storage & handling: Hydrogen peroxide, aqueous solution, stabilized, with more than 60% hydrogen peroxide should be stored in compatible vented oxidizer-rated containers away from heat, sunlight, fuels, organics, metals, reducing agents and contamination. Use clean compatible secondary containment and follow SDS temperature limits.
UN 2015 Quick Details
Common Hazards of UN 2015
- STRONG OXIDIZER; concentrated hydrogen peroxide may explode from heat, friction or contamination.
- Accelerates burning and may ignite combustibles such as wood, paper, oil or clothing.
- Can react violently with fuels, organics, metals, reducing agents or incompatible absorbents.
- Decomposition can release oxygen, heat and pressure rapidly.
- Liquid and vapor/mist can cause severe burns to eyes, skin and respiratory tissue.
- Runoff may create fire/explosion hazards and spread oxidizer contamination.
- Containers may rupture or explode when heated or contaminated.
Chemical Identity & Physical Properties
Colorless to pale blue liquid with a slightly sharp odor. Strong oxidizer. Concentrated solutions (>60%) are highly reactive and unstable.
| 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 |

PPE Requirements
Use positive-pressure SCBA and chemical protective clothing compatible with strong oxidizers. Level A may be needed for concentrated solution, vapor/mist or unknown exposure levels.
Isolation & Evacuation
First Actions for a UN 2015 Incident
- CALL 911. Then call the emergency response telephone number on the shipping paper, if available.
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Avoid breathing dust, vapor, fumes, mist or smoke and avoid skin or eye contact.
- Keep fuels, oils, organics, metals, reducing agents and contaminated absorbents away from the oxidizer.
- Do not touch damaged containers or spilled material unless properly trained and wearing appropriate protective equipment.
- Ventilate closed spaces before entering, but only if properly trained, equipped, monitored and authorized by incident command.
- Isolate the spill or release area and expand the perimeter for fire involvement, water reaction, vapor generation, dust spread or unknown product identity.
- Use ERG Guide 143, shipping papers, SDS, air monitoring and incident command for protective actions.
