UN 2807 Quick Details
UN 2807
Product name: Magnetized material
DOT Class: 9
Placard type: Miscellaneous
ERG Guide: 171 (check current ERG)
Initial isolation: ERG 171: No evacuation distances specified for magnetic materials; primary concern is magnetic field interference with navigation equipment, pacemakers, and electronic devices; maintain safe distance from sensitive equipment
Common Hazards of UN 2807
- Some may burn but none ignite readily.
- Containers may explode when heated.
- Some may be transported hot.
- For UN3508, Capacitor, asymmetric, be aware of possible short circuiting as this product is transported
- Polymeric beads, expandable (UN2211) may evolve flammable vapours.
- Inhalation of material may be harmful.
- Contact may cause burns to skin and eyes.
- Inhalation of Asbestos dust may have a damaging effect on the lungs.
Chemical Identity & Physical Properties
| Also known as | Magnetic materialsPermanent magnetsMagnetized metalMagnetic assembliesMagnetized articles |
| Appearance | Solid materials (metals, alloys, or composites) that have been magnetized and possess magnetic properties. Appearance varies widely depending on the specific material - typically metallic gray, black, or colored if coated. May be in various forms: blocks, bars, discs, or assembled components. |
| Flash Point | Not applicable (solid magnetic materials are typically non-flammable metals or alloys) |
| Boiling Point | Not applicable (varies by material; typically high melting point metals such as iron ~1538C, nickel ~1455C, or rare earth alloys) |
| Vapor Density | Not applicable (solid material) |
| Water Reactivity | No significant reaction under normal conditions; magnetic properties unaffected by water |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 2807
Extinguishing Media
Use appropriate extinguishing media for surrounding fire (dry chemical, CO2, water spray for cooling); magnetic materials themselves do not burn readily
PPE Requirements
⚠️ Standard firefighting PPE and SCBA; be aware of magnetic attraction to ferrous metals in equipment; handle with care around electronic devices and pacemakers
Isolation & Evacuation
ERG 171: No evacuation distances specified for magnetic materials; primary concern is magnetic field interference with navigation equipment, pacemakers, and electronic devices; maintain safe distance from sensitive equipment
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 171).
First Actions for a UN 2807 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.
- 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
