Section III 鈥? Physical
Welding consumables applicable to this sheet as shipped, consist of odorless, solid rods or wire, which have a metallic
luster. As shipped, these products are nonflammable, non-explosive, non-reactive, and non-hazardous
Section IV 鈥? Fire and Explosion Hazard
These items are not reactive, flammable, or explosive and essentially not hazardous at ambient temperatures. Welding
arcs and sparks can ignite combustibles and flammable products. If involved in a fire, these products may generate
irritating aluminum fumes and a variety of metal oxides. Emergency responders must wear personal protection
equipment suitable for the situation. Use the extinguishing media recommended for the burning materials and fire
situation. See ANSI Z49.1 鈥淪afety in Welding an 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.
Section V 鈥? Health Hazard Data
Welding 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.
Route of overexposure: The primary route of entry of the decomposition products is by inhalation. Skin contact, eye
contact, and ingestion are possible.
Effects of Acute (Short-Term) Overexposure: Short-term (acute) 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
chromium/chromate in fume can cause irritation of nasal membranes and skin. The presence of nickel compounds in
fume can cause metallic taste, nausea, tightness of chest, fever, and allergic reaction.
Excessive inhalation or ingestion of manganese can produce manganese poisoning. Overexposure to manganese
compounds may affect the central nervous system, symptoms of which are languor, sleepiness, muscular weakness,
emotional disturbances, and spastic gait resembling Parkinsonism. These symptoms can become progressive and
permanent if not treated. Excessive inhalation of fumes may cause 鈥淢etal Fume Fever鈥? with Flu-like symptoms such
as chills, fever, body aches, vomiting, seating, etc.
Pre-existing Medical Conditions Aggravated by Overexposure: Individuals with allergies or impaired respiratory
function may have symptoms worsened by exposure to welding fumes.
Effects of Chronic (Long-Term) Overexposure: Long-term (Chronic) 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 exposure. The changes seen are not necessarily associated with symptoms or
signs of reduced lung function or disease. In addiction, the changes on X-rays may be caused by non-work factors such
as smoking, etc. Nickel and chromium are considered carcinogenic. Long-term overexposure to nickel fumes may also
cause pulmonary fibrosis and edema. Overexposure to manganese compounds may affect the central nervous system,
symptoms of which are languor, sleepiness, muscular weakness, emotional disturbances, and spastic gait.
Excessive inhalation or ingestion of manganese can produce manganese poisoning. Overexposure to manganese
compounds may affect the central nervous system, symptoms of which are languor, sleepiness, muscular weakness,
emotional disturbances, and spastic gait resembling Parkinsonism. These symptoms can become progressive and
permanent if not treated. Excessive inhalation of fumes may cause 鈥淢etal Fume Fever鈥? with Flu-like symptoms such
as chills, fever, body aches, vomiting, seating, etc.
CARCINGOGENICITY: Certain hexavalent chromium compounds, nickel metal and compounds and respirable
crystalline silica are listed in the National Toxicology Program (NTP) Annual Report on Carcinogens, found to be a
potential carcinogen in the International Agency for Research on Cancer (IARC) Monographs, or listed by
OSHA/ACGIH as potential
California proposition 65: This product contains or produces a chemical known to the Stat of California to cause
cancer and birth defects (or other reproductive harm). (California Health and Safety Code 搂 25249.5 et seq.)
EU RoHS: Welding Wire and electrodes contain Chromium. When welded Welding products will produce Cr VI
(hexavalent chrome), however, the weld deposit does not contain Cr VI as it will be in the zero valent state or as Cr III
as an oxide. Finished products manufactured using welding wire and electrodes will not contain Cr VI
VI 鈥? Reactivity Data
Hazardous Decomposition Products: Welding fumes and gases cannot be classified simply. The composition and
quantity of both are dependent upon the metal being welding, the process, procedure and welding consumables used.
Other conditions which also influence the composition and quantity of the fumes and gases to which workers may be
exposed include: coating on the metal being welded (i.e. paint, painting, galvanizing), the number of welder, the
volume of the work area, the quality and the amount of ventilation, the position of the welders head with respect to the
fume plume, as well as the presence of contaminants in the atmosphere (such as chlorinated hydrocarbon vapors from
the cleaning and degreasing activities).
When an electrode is consumed, the fume and gas decomposition products generated are different in percent and form
from the ingredients listed in Section II. Fume and gas composition, and not the ingredients in the electrode, are
important. The concentration of a given fume or gas component may decrease or increase by many times the original
concentration. Also, new compounds not in the electrodes may form. Decomposition products of normal operation
include those origination from the volatilization, reaction or oxidation of the material shown in Section II, plus those
from the base metal coating, etc., as noted above.
Reasonable expected fume constituents of this product would include: Complex oxides of iron, manganese, silicon,
chromium, nickel, columbium, molybdenum, copper, carbon dioxide, carbon monoxide, ozone and nitrogen oxides.
Some products will also contain antimony, barium, molybdenum, aluminum, columbium, magnesium, strontium,
tungsten, and or zirconium. Fume limit for chromium, nickel and or manganese may be reached before limit of 5
mg/m3 of general welding fumes is reached.
Most welding, even with primitive ventilation, does not produce exposures within the welding helmet above 5mg/m3.
That which does should be controlled.
Section VII 鈥? Spill or Leak Procedures
This product is not hazardous per 49 CFR 172.101 by the U.S. Department of Transportation.
Section VIII 鈥? Special Protection Information
Ventilation: Use enough ventilation, local exhaust at the arc (or flame), or both, to keep the fumes and gases below the
PEL鈥檚, TLV鈥檚 and STEL鈥檚 in the workers breathing zone and general area. Train the employee to keep his head out of
the fumes. See ANSI/ASC Z49.1 Section 5.
Respirator Protection: Use respirable fume respirator or air-supplied respirator when welding in confined area, or
where local exhaust or ventilation does not keep exposure below TLV/PEL. Respirator selection and use should be
based on contaminant type, form and concentration. Follow OSHA 1910.134, OSHA 1910.1026, ANSI Z88.2 and
good industrial Hygiene practice.
IMPORTANT: SPECIAL VENTILATION AND/OR EXHAUST REQUIRED: Overexposure to manganese can
irreversibly affect the central nervous system resulting in impaired speech and movement. Fumes from the normal use
of this product contain manganese compounds. The TLV (Threshold Limit Value) for manganese exposure, 0.2
mg/m3, may be exceeded. Use enough ventilation, local exhaust and respirators to keep the workers鈥? breathing zone
and general area below the TLV for exposure to manganese.
Eye Protection: Arc Rays can injure your eyes. Wear helmet or face shield with filter lens of appropriate shade
number. See ANSI/ASC Z49.1 Section 4.2. Provide protective screens and flash goggles, if necessary, to shield
others.
Protective Clothing: Wear head and body protection, which help to prevent injury from radiation, sparks, flame and
electrical shock. See ANSI Z49.1. 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 employee not
to touch live electrical parts and to insulate him/herself from work and ground. Welders should not wear short sleeve
shirts or short pants.
Waste Disposal Method: Prevent waste for contamination surrounding environment. Discard any product of residue
in a disposable container or liner in an environmentally approved manner under full compliance with federal, state and
local regulations.
Emergency First Aid: Remove from dust of fume exposure immediately and seek medical attention. If breathing has
stopped perform artificial respiration and summon emergency medical aid.
