Handling and Disposal
*
Spill Release Procedures: SMALL/LARGE SPILL: FINE TURNINGS SHOULD BE SWEPT OR
  VACUUMED. SCRAP METAL CAN BE RECLAIMED FOR RE-USE.
Neutralizing Agent: NONE SPECIFIED BY MANUFACTURER.
Waste Disposal Methods: USED OR UNUSED PRODUCT SHOULD BE DISPOSED OF IN
  ACCORDANCE WITH FEDERAL, STATE OR LOCAL LAWS AND REGULATIONS. DISPOSER MUST
  COMPLY WITH FEDERAL, STATE AND LOCAL DISPOSAL OR DISCHARGE LAWS.
Handling And Storage Precautions: KEEP CONTAINER CLOSED. IN WELDING, PRECAUTION
  SHOULD BE TAKEN FOR AIRBORNE CONTAMINANTS WHICH MAY ORIGINATE FROM COMPONENTS
  OF THE WELDING ROD.
Other Precautions: ARC OR GENERATED SPARK WHEN WELDING OR BURNING COULD BE A
  SOURCE OF IGNITION FOR COMBUSTION AND FLAMMABLE MATERIALS. AVOID GENERATION
  OF AIRBORNE FUME AND DUST.
