NOTE: Fumes may be generated during the use of these electrodes. To appropriately assess inhalation hazards, one recommended way to determine the
composition and quantity of fumes and gases to which workers are exposed is to take an air sample in the workers breathing zone. See ANSI/AWS F1.1, from the
American Welding Society, 550 NW LeJeune Rd., Miami, FL 33126.
SARA SECTION 313 SUPPLIER INFORMATION: These products contain the following chemicals subject to the reporting requirements of Section 313 of the
Emergency Planning and Community Right-To-Know Act of 1986 (per 40 CFR 372). Thorium Oxide
SECTION 3 - HAZARD IDENTIFICATION
There are no immediate hazards with these electrodes. The chief acute health hazard associated with these products is inhalation of fumes during welding
operations. The Inhalation of fumes generated by welding or dusts and powders, formed if grinding operations are performed on the product. Those electrodes that
contain Thorium Oxide have a special hazard if dusts or powders are produced and inhaled during use or grinding of tips of the electrodes, as thorium compounds are
suspected of being cancer-causing compounds. When exposed to extremely high temperatures, these products will produce irritating oxides of cerium, thorium,
tungsten and zirconium. These electrodes present no significant fire hazard; however finely divided metal powder which may be generated during grinding of the tips
of electrodes, is highly flammable (especially when exposed to oxidizing compounds at elevated temperatures). In some circumstances, powdered tungsten can be
spontaneously flammable.
CARCINOGENICITY STATUS: Chemicals in these electrodes are listed, as follows.
THORIUM OXIDE: IARC-1, Carcinogenic to Humans ZIRCONIUM OXIDE: TLV-A4, Not Classifiable as to Human Carcinogenicity
The other components of these products are not found on the following lists: FEDERAL OSHA Z LIST, NTP, IARC, and CAL/OSHA, and therefore are not
considered to be, nor suspected to be, cancer-causing agents by these agencies.
CALIFORNIA SAFE DRINKING WATER AND TOXIC ENFORCEMENT ACT (PROPOSITION 65): Thorium Oxide is a component of some of these alloys and is
on the Proposition 65 list. The State of California requires the following information: WARNING: This product may contain chemicals, and when used
for welding may produce fumes or gases containing chemicals, known to the State of California to cause cancer, and/or birth defects (or other
reproductive harm.)
SECTION 4 - FIRST-AID MEASURES
SKIN: If the product’s fumes irritate the skin, begin decontamination with running water. Minimum flushing is for 15 minutes.
EYES: If the product’s fumes irritate the eyes, flush eyes under gently running water. Minimum flushing is for 15 minutes.
INHALATION: Move victim to fresh air. If necessary, use artificial respiration.
INGESTION: If swallowed call physician immediately! Do not induce vomiting unless directed by medical personnel. Rinse mouth with water if person is conscious.
Never give fluids or induce vomiting if person is unconscious, having convulsions, or not breathing.
VICTIMS OF CHEMICAL EXPOSURE MUST BE TAKEN FOR MEDICAL ATTENTION, ESPECIALLY IF ADVERSE EFFECTS CONTINUE AFTER FIRST-AID
TREATMENT. REFER TO SECTION 11 FOR ADDITIONAL TREATMENT INFORMATION!

 

SECTION 5 - FIRE-FIGHTING MEASURES
For Electrode:
FLASH POINT: Not applicable
AUTOIGNITION TEMPERATURE: Not determined.
FLAMMABLE LIMITS: Not applicable
FIRE EXTINGUISHING MATERIALS:

    

Water Spray : Halon:	YES (for cooling) Carbon Dioxide: YES
YES	Foam: YES Other: Any "ABC" Class.
Dry Chemical: YES

For Powders of Tungsten: Powders of Tungsten are considered
to be a Class D Fires. Use Soda Ash, Lime, DRY Sand (Purple K,
if available). DO NOT USE WATER
EXPLOSION SENSITIVITY TO MECHANICAL IMPACT: Not sensitive.
EXPLOSION SENSITIVITY TO STATIC DISCHARGE: The finely divided powders of these products may ignite if exposed to static electrical discharge.
FIRE HAZARDS: During a fire, irritating fumes (e.g., tungsten oxide compounds) may be generated.
FIRE-FIGHTING PROCEDURES: Structural firefighters must wear Self-Contained Breathing Apparatus and full protective equipment.
UNUSUAL FIRE AND EXPLOSION HAZARDS: When Thorium Oxide-containing electrodes are involved in a fire, incipient fire fighters must wear a respirator
approved for radionuclides. When exposed to extremely high temperatures, these products will produce irritating oxides of cesium, thorium, tungsten and zirconium
(depending on composition - see Section 2, Composition and Information on Ingredients). These electrodes present no significant fire hazard. Finely divided
tungsten powder, however, is highly flammable (especially when exposed to oxidizing compounds at elevated temperatures).
SECTION 6 - ACCIDENTAL RELEASE MEASURES
Not applicable.
SECTION 7 - HANDLING and STORAGE
All employees who handle these materials should be trained to handle them safely. Avoid breathing fumes during welding operations. Store these electrodes in a
cool, dry location, away from direct sunlight, sources of intense heat, or where freezing is possible. Store away from incompatible chemicals (see Section 10,
Stability and Reactivity). Inspect all incoming containers before storage to ensure they are properly labeled and not damaged. If these products are used during
welding operations, it is recommended that the requirements of the Federal Occupational Safety and Health Welding and Cutting Standard (29 CFR 1910 Subpart Q)
and the Standards of the American National Standards Institute for Welding and Cutting (ANSI Z49.1) be followed. Use ventilation and other engineering controls to
minimize potential exposure to fumes during welding operations or to dusts if tips of electrodes are ground. Follow good housekeeping practices to ensure powders
or dusts from grinding operations do not accumulate, which can be highly flammable and can pose special health hazards if from thorium-containing electrodes.
Tungsten-Thorium Oxide alloys are generally safe to handle during use and almost all normal conditions and environments. Special precautions must be taken
during the grinding or machining of tips of electrodes that contain Thorium Oxide to avoid the generation and subsequent inhalation of dusts from these
operations. Any dusts generated during these operations may be considered as “Source Material”, as defined by the Nuclear Regulatory Commission,
and therefore be subject to the requirements of 10 CFR, Parts 20 and 40. Routine wet mopping or vacuuming with an explosion-proof vacuum, fitted with a
HEPA filter may be considered to reduce accumulation of dusts.
SECTION 8 - EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: Use with adequate ventilation to ensure exposure levels are maintained below the limits provided in Section 2
(Composition and Information on Ingredients). Ensure eyewash/safety shower stations are available.
RESPIRATORY PROTECTION: If respiratory protection is needed, use only protection authorized in the U.S. Federal OSHA Standard (29 CFR 1910.134),
applicable U.S. State regulations, or the appropriate standards of Canada and its Provinces. It is suggested that NIOSH guidelines for Welding Fumes are followed.
For further information, see full MSDS for these products.
EYE PROTECTION: Safety glasses. When used during welding, wear safety glasses, goggles or faceshield with filter lens of appropriate shade number. (see
ANSI Z49.1, “Safety in Welding and Cutting”), as necessary.
HAND PROTECTION: Wear gloves that will protect against heat of metal product.
BODY PROTECTION: None needed for normal circumstances of use. Use body protection appropriate for task (i.e., leather apron, and coveralls).

Weling fumes and gases cannot be classified simply. The composition and quantity of both are dependent upon the metal beging welded, the process, procedure and electrodes used. Other conditions which also influence the composition and quantity of the fumes and gases to which workers may be exposed included: coatings on the metal being welded (such as paint , plating, fluxes, or galvanizing), the number of welders and the volume of work area, the quality and amount of ventilation, the position of the welder’s  head with respect to the fume plume, as well as the presence of contaminants in the atmosphere(such as chlorinated hydrocarbon vapors from cleaning and decreasing activities).

When the electrode is consumed, the fume and gas decomposition products generated may be different in percent and form to the ingredients listed in Section 2. Fume and gas decomposition products, 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 in the electrode.

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 materials shown in Section 2, plus those from the base metal and coating, etc.as noted above.

Reasonably expected decomposition products from normal use of these products include a complex of the oxides of the materials listed in Section 2, as well as carbon monoxide, carbon dioxide, ozone and nitrogen oxides. The fume limit for manganese may be reached before the general limit for welding fumes(5mg/m3) is reached.

One recommended way to determine the composition and quantity of fumes and gases to which worker’s breathing zone.

See applicable OSHA guidelines and ANSI/AWS F1.1 “Method for Sampling Airborne Particles Generated by Welding and Allied Process” and “Characterizations of Arc Welding Fume” available from the American Welding Society, 550 N.W. LeJeune Road, Miami,FL 33126

Electric arc welding or oxy fuel welding may create one or more of the following health hazards:

ARC RAYS AND HEAT RAYS: Arc rays from the welding process produce intense heat and strong ultraviolet rays that can burn eyes and skin.

ELECTRIC SHOCK: Electric shock can kill. Do not touch live electrical parts.

NOISE can damage hearing.

SHORT TERM (ACUTE) OVEREXPOSURE: Short-term overexposure to welding fumes may result in discomport such as fever, dizziness, nausea, or dryness or irritation of the nose, throat, eyes, and may aggravate pre-existing respiratory conditions.

LONG TERM (CHRONIC) OVEREXPOSURE: Long-term overexposure to welding fumes may harm your pulmonary and respiratory functions and may lead to siderosis(iron deposits in the lungs).

MANGANESE IN FUMES: Fumes from the normal use of this product contain significant quantities of manganese compounds. The Threshold Limit Value(TLV) for manganese is 0.2mg/m3 and will be exceeded before reaching the 0.5mg/m3 maximum.
