  • Not applicable
• SECTION IV - FIRE AND EXPLOSION HAZARD DATA
  • Non Flammable: See Section IX
• SECTION V - HEALTH HAZARD DATA
  • Route of Entry: Inhalation.
  • Effects of Overexposure: Metallic taste, headache.
  • Emergency and First Aid Procedure: Remove to fresh air and call physician.
  • Eye Hazard: See Section VIII.
  • Carcinogenicity: Nickel and Chromium with their compounds are known probable carcinogens.
  • See Note 2.
• SECTION VI - REACTIVITY DATA
  • Stability: Stable
  • Conditions to avoid: None
  • Incompatibility (Materials to Avoid): None.
  • Hazardous Decomposition Products: Under certain conditions, oxides of the metals listed in Section II may be present in the welding fumes.*
  • Hazardous Polymerization: Not applicable
  *Carbonates can decompose into CO2 and CO. TLV for CO is 50 PPM.
• SECTION VII - SPILL OR LEAK PROCEDURES
  • Not applicable
• SECTION VIII - SPECIAL PROTECTION INFORMATION (See Note 1)
  • Respiratory Protection: Weld fume respirator or air-line respirator for confined space or where exposures are above TLV.

  • Mechanical (General): Not applicable if local exhaust is adequate.
  • Eye Protection: Up to 5/32" diam., use #10 lens; for 3/16" diam., and larger use #12 lens.
  • Viewing electric arc without protection can result in severe eye damage.
  • Protective Gloves: Welder's protective gloves. Unprotected skin can be severely burned by the electric arc.
  • Other Protective Equipment: Equipment as required by welding conditions. Dark clothing should be worn to protect skin from electric arc burning.
• SECTION IX - SPECIAL PRECAUTIONS (See Note 1)
  • Other Precautions: Arc and sparks could be source of ignition of combustible products.
  • Nearby personnel should be warned against direct viewing of welding arc without the proper eye protection.
• NOTE 1
  • For additional information, see American National Standard Safety in Welding & Cutting Z49.1-1967
    (American Welding Society Publication Z49.1-1967).
• NOTE 2
  • State of California knows that welding produces compounds that can cause cancer, birth defects or other reproductive harm.
