SECTION V - REACTIVITY DATA
HAZARDOUS DECOMPOSITION PRODUCTS:
Welding fumes cannot be classified simply. Their composition and quantity are dependent upon the metal being welded, the
process, procedures and electrodes used. Other conditions which also influence the composition and quantity of the fumes and
gases to which workers may be exposed include: coatings on the metal being welded (such as paint, plating, or galvanizing),number
of welds and volume of work area, quality and amount of ventilation, position of welder鈥檚 head with respect to thefume plume, as
well as the presence of contaminants in the atmosphere (such as chlorinated hydrocarbon vapors from cleaning and degreasing
activities).
When the electrode is consumed, the fume and gas decomposition products are different in percent and form from the ingredients
listed in Section II. Fume and gas decomposition products, not the ingredients in the electrode, are important. Decomposition
products include those originating from the volatilization, reaction, or oxidation of the materials shown in Section II plus those from
base metal, coating, etc. as noted above. These components are virtually always present as complex compounds and not as metals
(Characterization of Arc Welding Fume: American Welding Society).
Reasonably expected fume constituents from these products would include fluorides and complex oxides of iron, manganese,
silicon, and, when present, nickel, chromium, molybdenum, and copper. Gaseous reaction products may include carbon monoxide
and carbon dioxide. Ozone and nitrogen oxides may be formed by the radiation from the arc.
One recommended way to determine the composition and quantity of fumes and gases to which workers are exposed is to take an air
sample inside the welders helmet, if worn, or in the worker鈥檚 breathing zone. ANSI/AWS F1.1, available from the American
Welding Society, P.O. Box 351040, Miami, FL 33135.
SECTION VI - HEALTH HAZARD DATA
Threshold Limit Value: The ACGIH recommended general limit for welding fume NOC (Not Otherwise Classified) is 5mg/m3.
The ACGIH 1984-1985 preface states: 鈥淭he TLV-TWA should be used as guides in the control of health hazards and should not be
used as firm lines between safe and dangerous concentration.鈥? See Section V for specific fume constituents which may modify this
TLV.
Effects of Overexposure: FUMES AND GASES can be dangerous to your health.
SHORT-TERM (ACUTE) OVEREXPOSURE to welding fumes may result in discomfort such as: dizziness, nausea, or dryness or
irritation of nose, throat, or eyes.
LONG TEAM (CHRONIC) OVEREXPOSURE may lead to siderosis (iron deposits in the lung) and is believed by some
inves-tigators to affect pulmonary function.
ARC RAYS can injure eyes and burn skin.
ELECTRIC SHOCK can kill. See Section VII.
Emergency & First Aid Procedures: Call for medical aid. Employ first aid techniques recommended by the American Red Cross.
Carcinogenicity: NOT APPLICABLE
SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE/APPLICABLE CONTROL MEASURES
Read and understand the manufacture鈥檚 instructions and the precautionary label on this product. See American National Standard
Z-49.1, Safety in Welding and Cutting, published by the American Welding Society, P.O. Box 351040, Miami, FL 33135 and OSHA
Publication 2206 (29 C.F.R. 1910), U.S.Government Printing Office, Washington, D.C. 20402 for more detail on many of the
following:
Ventilation: Use enough ventilation, local exhaust at the arc, or both, to keep the fumes and gases below the TLV鈥檚 in the worker鈥檚
breathing zone and the general area. Train the welder to keep his head out of the fumes.
Respiratory Protection: Use respirable fume respirator or air supplies repirator when welding in confined space or where local
exhaust or ventilation does not keep exposure below TLV.
Eye Protection: Wear helmet or use face shield with filter lens. As a rule of thumb, start with a shade which is too dark to see the
weld zone. Then go to the next lighter shade which gives sufficient view of the weld zone. Provide protective screens
and flash goggles, if necessary, to shield others.
Protective Clothing: Wear head, hand and body protection which help to prevent injury from radiation, sparks and electrical
shock. See ANSI Z-49.1. At a minimum, this includes welder鈥檚 gloves and a protective face shield and may include arm
protectors, aprons hats, 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.
Procedure for Cleanup of Spills or Leaks: NOT APPLICABLE
Waste Disposal Method: Prevent waste from contaminating surrounding environment. Discard any product, residue, disposable
container, or liner in an environmentally acceptable manner, in full compliance with Federal, State and Local regulations.
