UN 2807 — Magnetized material
Placard: Miscellaneous. ERG Guide 171. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
🚒☣️
⚠️ Verification required:
Broad or variable material category; verify exact product, SDS and shipping papers.
⚠️ This page is a quick-reference aid. For real incidents: stage upwind, isolate, deny entry, request Hazmat early, and consult the current ERG + SOP/SOG.
Magnetized material is a Class 9 entry for materials or assemblies with magnetic fields strong enough to affect transport safety. The primary issue is interference, not chemical toxicity.
Hazard overview: The hazard depends on field strength, shielding and packaging. Strong magnetic attraction can injure handlers or affect medical devices, navigation equipment and electronics.
Response guidance: Keep sensitive equipment and implanted-device wearers away from damaged packages. If fire is present, use media for the packaging and surrounding materials while maintaining awareness of magnetic attraction.

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
- Magnetic fields can interfere with navigation instruments, pacemakers and sensitive electronics.
- Strong magnets can attract ferrous tools, cylinders or debris suddenly and cause injury.
- Fire hazards depend on the packaging and the specific magnetic assembly, not the magnetic field alone.
- Heated containers or surrounding materials may fail or produce smoke.
- Some magnetized articles may contain brittle or sharp components if broken.
- Improper handling may damage aircraft, vehicle or communication equipment.
- Exact precautions depend on field strength, packaging and transport mode.
Chemical Identity & Physical Properties
The shipment may include blocks, discs, assemblies or packaged components. Appearance varies widely and may not reveal field strength.
| 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.

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
Use standard incident PPE appropriate to the packaging, fire and mechanical hazards. Avoid bringing loose ferrous tools or devices close to strong magnets.
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 or the responsible carrier/shipper if a transport incident creates damage or exposure concerns.
- Keep unauthorized personnel away from damaged packages or scattered magnetic assemblies.
- Keep magnetized material away from pacemakers, implanted medical devices and sensitive electronics.
- Use caution with ferrous tools, cylinders and equipment that may be pulled toward strong magnets.
- If fire is present, stay upwind and use extinguishing media suitable for the surrounding materials.
- Do not dismantle packages or assemblies unless trained for the specific shipment.
- Verify air-transport markings, shipping papers and carrier instructions before moving the load.
