Section 3 - Hazard ID and Emergency Overview
WARNING: Protect yourself and others. Read and understand this information. When this product is used for it's intended purpose
fumes and gases produced as a byproduct can be hazardous to your health. Aggravation of pre-existing respiratory or allergic conditions
may occur in some workers. Arc Rays can injure eyes and burn skin. Electric shock can kill.
SHORT-TERM EXPOSURE: Metallic taste; nausea; tightness of chest; fever; irritation of eyes, nose, throat and skin; loss of
consciousness/death due to welding gases or lack of oxygen.
LONG-TERM EXPOSURE: Adverse effects may result from long-term exposure to welding fume, gases, or dusts. These effects may
include skin sensitization, neurological damage, and respiratory disease such as bronchial asthma, lung fibrosis or pneumoconiosis.
Chromium and nickel, and their compounds, are on the International Agency for Research on Cancer (IARC) and the National
Toxicology Program (NTP) lists as posing a carcinogenic risk to humans.
EXPOSURE LIMITS: The ACGIH recommended exposure limit for total welding fumes is 5mg/m3. OSHA requires employers to
ensure exposures below individual constituent PEL's (See Section 3). Determine actual exposure by industrial hygiene monitoring.
Section 4 - First Aid Measures
EMERGENCY AND FIRST AID: Remove from exposure and obtain prompt medical attention. If victim is unconscious, administer
oxygen. If not breathing, resuscitate immediately. If flu-like symptoms (cough, muscle pain, fever, chills, insomnia, or mental confusion)
develop after use, obtain medical help immediately.
Section 5 - Fire and Explosion Hazard Data
Flammability: This material is not flammable. However, welding arc and sparks can ignite combustibles.
National Fire Protection Association (NFPA) Rating: Health - 2 Flammability - 0 Reactivity ?0
Note: The NFPA Health rating is based on the fumes generated during normal use.

Section 6 - Spill or Leak Procedure
Spill of Leak Procedure: Not Applicable
Section 7 - Handling and Storage
Precautions: None.
Section 8 - Exposure Controls & Personal
Read and understand the manufacturer's instructions and the precautionary label on this product. See American National Standard
Z49.1:1999, Safety in Welding, Cutting and Allied Processes published by the American Welding Society, 550 N.W. LeJeune Rd., Miami,
FL 33126 (www.aws.org); OSHA Safety and Health Standards, available from the U.S. Government Printing Office, Superintendent of
Documents, P.O. Box 371954, Pittsburgh, PA 15250-7954. (www.osha.gov).
VENTILATION: Use enough ventilation and/or local exhaust to keep fumes and gasses from you breathing zone and below all published
exposure limits (See Section 10). To avoid exposure to metal fumes additional ventilation may be needed when welding on coated metals,
such as painted, galvanized, or plated parts. Proper use of an appropriate respirator may be necessary when welding in a confined space,
or if ventilation is inadequate. Train the welder to keep his head out of the fumes.
RESPIRATORY PROTECTION: Use air-purifying fume respirator or air-supplied respirator when welding in confined space or where
local exhaust or ventilation does not keep exposure below PEL, TLV, REL and STEL levels.
EYE PROTECTION: Wear welding helmet or use face shield with filter lens, Shade No. 10 or darker. Provide protective screens or
flash goggles if necessary to shield others.
PROTECTIVE CLOTHING: Wear hand, head and body protection which help to prevent injury from radiation, sparks and electrical
shock (see ANSI-Z49.1). At a minimum, this includes welder's gloves and a protective face shield, and may include arm protectors,
aprons, hats, and shoulder protection as well as dark, substantial clothing. Train the welder not to touch live electrical parts and to insulate
himself from work and ground.
Section 9 - Physical and Chemical Properties
Welding wire is a solid metal, shaped as wire of various diameters, which may be gray or copper colored.
Density: 489.6 lbs/ft3 Melting Point: 2700 oF
Section 10 - Stability & Reactivity Information
Materials to Avoid: Avoid contact with mineral acids and oxidizing agents which may generate hydrogen gas.
Stability Condition to Avoid: None
Hazardous Polymerization: Will Not Occur
Hazardous Decomposition Products: Welders are exposed to a range of fumes and gases. Fume particles contain a wide variety of
oxides and salts of metals and other compounds, which are produced mainly from electrodes, filler wire and flux materials. Fumes from
the welding of stainless-steel and other alloys contain nickel compounds and chromium [VI] and [III]. Ozone is formed during most
electric arc welding, and exposures can be high in comparison to the exposure limit, particularly during metal inert gas welding of
aluminum. Oxides of nitrogen are found during manual metal arc welding and particularly during gas welding. Welders who weld painted
mild steel can also be exposed to a range of organic compounds produced by pyrolysis.
