Section 4 - Fire and Explosion Hazard Data
Flash Point: N/A
FLAMMABLE LIMITS: N/A
LEL: N/A

Extinguishing Media: Dry chemicals without Oxygen compounds.
Special Fire Fighting Procedures: Do not use Halon agents or water. Isolate and contain source of fire. Smother with dry chemical or blanket with dry argon or nitrogen gas.
Unusual Fire and Explosion Hazards(s): Powder will oxidize and burn rapidly and intensely when exposed to atmosphere or oxygen. Rare earth metals burn vigorously in halogen vapors above 392 F. May re-ignite after fire is extinguished. Probably will react violently with water and liberate hydrogen.
Section 5 - Reactivity Data
Stability: Stable
Conditions to Avoid: N/A
Incompatibility (Materials to Avoid): Oxygen, atmosphere, halogenated hydrocarbons, strong oxidizers.
Hazardous Decomposition or Byproducts : Hydrogen may be released when powders react with water.
Hazardous Polymerization: Will not occur.
Section 6 - Health Hazard Data
Health Hazards (Acute & Chronic): Under normal handling and use, exposure to Neo presents few or no health hazards. Skin or eye irritation in sensitive individuals may occur.

Section 7 - Precautions for Safe Handling and Use
Spill Procedure: Prevent integration of material with oxidizing substances. Brush up material and seal in an airtight container.
Waste Disposal Method: Store waste in water filled cans. Add powder to water. Store powder under inert atmosphere in non-combustible containers. Treat as a flammable solid. Keep powder away from ignition sources and oxidizers. Use water during machining processes to control sparking of the swarf.
Section 8 Control Measures
Respiratory Protection: With powders or dust use proper ventilation and/or respiratory protection.
Eye Protection: Protected goggles are recommended when working on finished parts or powder due to chipping and breaking tendencies.
Skin Protection: Protect open wounds, cuts, or abrasions from direct contact with dust or powder.
Ventilation: Local Exhaust: Use for dust and iron fumes when machining or pulverizing.
Work / Hygienic Practices: Always handle with care, do not risk fire.
WARNING: RARE EARTH MAGNETS ARE EXTREMELY POWERFUL! They have very strong magnetic forces which make them attract to other magnets and other ferromagnetic materials such as iron or steel. HANDLE WITH EXTREME CAUTION!
