Ingestion: NO
Carcinogenicity Inds - NTP: NO
IARC: NO
OSHA: NO
Effects of Exposure: EMERGENCY OVERVIEW: MINOR HEALTH HAZARD; NO UNUSUAL SPILL
  HAZARD. GREY OR BLACK METAL WITH NO ODOR. ACUTE: EYES: CAN CAUSE IRRITATION.
  SKIN: CAN CAUSE IRRITATION. INHALATION: CAN IRRITATE THROAT AND M ILDLY
  IRRITATE MUCOUS MEMBRANES; MAY EXPERIENCE METALLIC TASTE IN MOUTH. INGESTION:
  NOT AVAILABLE. ACUTE OVEREXPOSURE: CAN CAUSE METAL FUME FEVER. CHRONIC
  OVEREXPOSURE: CAN CAUSE PULMONARY EFFECTS, SI DEROSIS, BRONCHITIS, LACK OF
  COORDINATION, OR BENIGN PNEUMOCONIOSIS OF THE LUNGS (STANNOSIS).
Explanation Of Carcinogenicity: NONE.
Signs And Symptions Of Overexposure: SEE HEALTH HAZARDS.
Medical Cond Aggravated By Exposure: NOT AVAILABLE.
First Aid: EYES: FLUSH THOROUGHLY WITH RUNNING WATER TO REMOVE PARTICULATE FOR
  WASHING THOROUGHLY WITH SOAP AND WATER. SEEK MEDICAL ATTENT ION IF CONDITION
  PERSISTS. INHALATION: REMOVE TO FRESH AIR; IF CONDITION CONTINUES, CONSULT A
  PHYSICIAN. INGESTION: IF SIGNIFICANT AMOUNTS OF METAL ARE INGESTED, CONSULT
  PHYSICIAN.

Handling and Disposal
*
Spill Release Procedures: SMALL/LARGE SPILL: FINE TURNINGS SHOULD BE SWEPT OR
  VACUUMED. SCRAP METAL CAN BE RECLAIMED FOR RE-USE.
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: STORAGE: KEEP CONTAINER CLOSED. HANDLING: 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.

Fire and Explosion Hazard Information 
*
Flash Point Text: NONE
Lower Limits: NONE
Upper Limits: NONE
Extinguishing Media: DO NOT USE WATER ON MOLTEN METAL. MEDIA SUITABLE FOR
  SURROUNDING FIRE (FP N).
Fire Fighting Procedures: USE NIOSH APPROVED SCBA & FULL PROTECTIVE
  EQUIPMENT (FP N). STEEL WIRE DOES NOT PRESENTA FIRE OR EXPLOSION HAZARD UNDER
  NORMAL CONDITIONS. FINE METAL PARTICLES SUCH AS PRODUCED WHEN SAWING OR
  GRINDING  CAN BURN. HIGH CONCENTRATIONS OF METALLIC FINES IN THE AIR MAY
  PRESENT AN EXPLOSION HAZARD.
*
*
Respiratory Protection: APPROPRIATE DUST/FUME/MIST RESPIRATOR SHOULD BE USED TO
  AVOID EXCESS INHALATION OF PARTICULATES. IF EXPOSURE LIMITS ARE REACHED OR
  EXCEEDED, USE NIOSH APPROVED EQUIPMENT.
Ventilation: AS REQUIRED DEPENDING ON OPERATIONS AND SAFETY CODES.
Other Protective Equipment: EYE WASH & DELUGE SHOWER MEETING ANSI DESIGN
  CRITERIA (FP N). AS REQUIRED DEPENDING ON OPERATIONS AND SAFETY CODES.
Supplemental Safety and Health: MFR TRADE NAME/PART NO: OXYGEN, OR SULFUR IN
  STEEL.
