Under what conditions: Only the packaging for this product will burn.
Extinguishing Media: This product will not burn; however, welding arcs and sparks can ignite combustible and flammable
materials. Use the extinguishing media recommended for the burning materials and fire situation. See ANSI Z49.1 鈥淪afety in
Welding and Cutting鈥? and 鈥淪afe Practices鈥? Code: SP, published by the American Welding Society, P. O. Box 351040, Miami, FL
33135, and NFPA 51B 鈥淐utting and Welding Processes,鈥? published by the National Fire Protection Association, Batterymarch Park,
Quincy, MA 02269 for additional fire prevention and protection information.
V. Reactivity Data
Stability: Stable (X) Unstable ( ) Polymerization will not occur
Incompatible products: None currently known
Hazardous decomposition products: Brazing fumes and gases cannot be classified simply. The composition and quantity of
both are dependent upon the material being worked, the process, procedures, and consumables 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 material
being worked (such as paint, plating or galvanizing), the number of welding operations and the volume of the work area, the quality
and amount of ventilation, the position of the worker鈥檚 head with respect to the fume plume, as well as the presence of contaminants
in the atmosphere (such as chlorinated hydrocarbon vapors from cleaning or painting activities). When the materials are consumed,
the fume and gas decomposition products generated are different in percent and form from the ingredients listed in Section II.
Decomposition products of normal operation include those originating from the volatilization, reaction, or oxidation of the ingredients,
plus those from the material being worked and the coatings etc. noted above.
Reasonably expected decomposition products from normal use of these products include a complex of the oxides of the
materials listed in Section II, as well as carbon monoxide, carbon dioxide, ozone and nitrogen oxides (refer to 鈥淐haracterization of
Arc Welding Fume鈥? available from the American Welding Society). THE FUME LIMIT FOR COPPER MAY BE REACHED BEFORE
3
THE GENERAL LIMIT FOR WELDING FUMES OF 5 mg/m IS REACHED. MONITOR FUMES FOR COPPER LEVELS. The only
way to determine the true identity of the decomposition products is by sampling and analysis. The composition and quantity of the
fumes and gases to which a worker may be overexposed can be determined from a sample obtained from inside the welder鈥檚
helmet, if worn, or in the workers breathing zone. See ANSI/AWS F1.1 鈥淢ethod for Sampling Airborne Particles Generated by
Welding and Allied Processes,鈥? available from the American Welding Society.
VI. Physical and Health Hazard Data
Electric arc working may create one or more of the following health or physical hazards. Fumes and gases can be dangerous to
your health. Electric shock can kill you. Arc rays can injure eyes and burn skin. Noise can damage hearing. Brazing alloys are
frequently used with a fluoride-type flux. If applicable, flux fume should be considered in evaluation of hazards.
Route of overexposure: The primary route of entry of the decomposition products is by inhalation. Skin contact, eye contact, and
ingestion are possible. Absorption by skin contact is unlikely. When these products are used as recommended by THE ESAB
GROUP, and ventilation maintains exposure to the decomposition products below the limits recommended in this section,
overexposure is unlikely.
Effects of acute (short-term) overexposure to the gases, fumes, and dusts may include irritation of the eyes, lungs, nose, and
throat. Some toxic gases associated with welding may cause pulmonary edema, asphyxiation, and death. Acute overexposure may
include signs and symptoms such as watery eyes, nose and throat irritation, headache, dizziness, difficulty in breathing, frequent
coughing, or chest pain. The presence of copper in fume can cause metal fume fever. Short term symptoms may include a metallic
taste in the mouth, dryness or irritation of the throat followed by coughing, shortness of breath, nausea, fever, body ache, and chills.
Symptoms usually disappear within 24 hours.
Pre-existing Medical Conditions Aggravated by Overexposure: Individuals with allergies or impaired respiratory function may
have symptoms worsened by exposure to welding fumes; however, such reaction cannot be predicted due to the variation in
composition and quantity of the decomposition products.

Effects of chronic (long-term) overexposure to air contaminants may lead to their accumulation in the lungs, a condition which
may be seen as dense areas on chest X-rays. The severity of the change is proportional to the length of the exposure. The
changes seen are not necessarily associated with symptoms or signs of reduced lung function or disease. In addition, the changes
on X-rays may be caused by non-work factors such as smoking, etc. Copper poisoning has been reported in the literature from
exposure to high levels of copper. Liver damage can occur due to copper accumulation in the liver; the damage is characterized by
cell destruction and cirrhosis. High levels of copper may cause central nervous system damage characterized by nerve fiber
separation and cerebral degeneration. Overexposure to phosphorus may cause necrosis of the mandible, termed 鈥減hossy jaw鈥?.
Overexposure to silver may result in argyria, a permanent pigmentation (gray to purple} of the skin and eyes. Exposure to high silver
levels has resulted in respiratory problems and stomach pains.
Exposure limits for the ingredients are listed in Section II. The ACGIH and the 1989 OSHA TWA for welding fume is 5 mg/m鲁. At
times the limit for a particular hazardous chemical is reached before the limit for welding fumes. TLV-TWAs should be used as a
guide in the control of health hazards and not as fine lines between safe and excessive concentrations. As noted in Section V, the
brazing fume is a mixture of many components. Therefore, a statutory computation of the equivalent exposure is required. The
equivalent exposure value for the brazing fume mixture shall always be less than one. When these products are used as
recommended by THE ESAB GROUP, and the preventive measures taught in this MSDS are followed, overexposure to hazardous
substances will not occur.
Emergency First Aid Measures: In case of emergency, call for medical aid. Employ first aid technique recommended by the Red
Cross. IF BREATHING IS DIFFICULT, give oxygen and call for a physician. FOR ELECTRIC SHOCK, disconnect and turn off the
power. If not breathing, begin artificial respiration, preferably mouth-to-mouth. If no detectable pulse, begin Cardio Pulmonary
Resuscitation (CPR). Immediately call a physician. FOR ARC BURN, apply cold, clean compresses and call a physician.
Carcinogenic Assessment (NTP Annual Report, IARC Monographs, Other): None
脢 WARNING: This product, when used for welding or cutting, produces fumes or gases which contain chemicals known to the State
of California to cause birth defects and, in some cases, cancer. (California Health & Safety Code 搂25249.5 et seq.)
VII. Precautions for Safe Handling and
Use/Applicable Control Measures
Read and understand the manufacturer鈥檚 instructions and the precautionary label on this product. See American National Standard
Z-49.1, 鈥淪afety in Welding and Cutting,鈥? 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, Superintendent of Documents, P.O. Box 371954,
Pittsburgh, PA 15250-7954 for more detail on many of the following:
Ventilation: Use enough ventilation, local exhaust at the arc, or both, to keep the exposure within legal limits. In the worker鈥檚
breathing zone and the general area, fumes and gases must be kept below the TLVs and the equivalent exposure must
compute to less than one. Train the welder to keep his head out of the fumes.
Respiratory Protection: Use respirable fume respirator or air supplied respirator when welding in confined space or where
local exhaust or ventilation does not keep exposure below TLVs.
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.
