=====================  Hazards Identification  =====================

Reports of Carcinogenicity:NTP:UNKNOWN	  IARC:UNKNOWN	  OSHA:YES
Health Hazards Acute and Chronic:ELECTRIC ARC-WELDING MAY CREATE ONE OR
    MORE OF THE FOLLOWING HEALTH HAZARDS: FUMES AND GASES CAN BE
    DANGEROUS TO YOUR HEALTH. ARC RAYS CAN INJURE EYES AND BURN SKIN.
    ELECTRIC SHOCK CAN KILL. SHORT TER M OVEREXPOSURE TO WELDING FUMES
    MAY RESULT IN DISCOMFORT SUCH AS: DIZZINESS, NAUSEA, DRYNESS OR
    IRRITATION OF NOSE, THROAT, EYES, TIGHTNESS IN CHEST, FEVER AND
    ALLERGIC REACTIONS. LONG TERM (CHRONIC)  OVEREXPOSURES TO WELDING
    FUMES MAY LEAD TO SIDEROSIS (IRON DEPOSIT IN LUNGS) AND IS BELIEVED
    BY SOME INVESTIGATORS TO AFFECT PULMONARY FUNCTION. CHROMIUM
    COMPOUNDS ARE REQUIRED TO BE CONSIDERED CARCIN OGENIC BY OSHA.
Explanation of Carcinogenicity:CHROMIUM COMPOUNDS ARE CONSIDERED
    CARCINOGENIC BY OSHA.
Effects of Overexposure:SHORT TERM OVEREXPOSURE TO WELDING FUMES MAY
    RESULT IN DISCOMFORT SUCH AS: DIZZINESS, NAUSEA, DRYNESS OR
    IRRITATION OF NOSE, THROAT, EYES, TIGHTNESS IN CHEST, FEVER AND
    ALLERGIC REACTIONS. LONG TERM ( CHRONIC) OVEREXPOSURES TO WELDING
    FUMES MAY LEAD TO SIDEROSIS (IRON DEPOSIT IN LUNGS) AND IS BELIEVED
    BY SOME INVESTIGATORS TO AFFECT PULMONARY FUNCTION.

=======================  First Aid Measures  =======================

First Aid:REMOVE TO FRESH AIR, OBTAIN MEDICAL ATTENTION. EMPLOY FIRST
    AID TECHNIQUES RECOMMENDED BY THE AMERICAN RED CROSS.

=====================  Fire Fighting Measures  =====================

Extinguishing Media:SEE BELOW.
Fire Fighting Procedures:WELDING ARC AND SPARKS CAN IGNITE COMBUSTIBLES
    AND FLAMMABLES. REFER TO AMERICAN NATIONAL STANDARD Z49.1 FOR FIRE
    PREVENTION DURING THE USE OF WELDING AND ALLIED PROCEDURES.
Unusual Fire/Explosion Hazard:WELDING ARC AND SPARKS CAN IGNITE
    COMBUSTIBLES AND FLAMMABLES.

======================	Handling and Storage  ======================

Handling and Storage Precautions:READ AND UNDERSTAND MANUFACTURER'S
    INSTRUCTIONS AND THE PRECAUTIONARY LABEL ON  PRODUCT. USE ENOUGH
    VENTILATION, LOCAL EXHAUST AT ARC, OR BOTH, TO KEEP FUMES AND GASES
    FROM  WORKER'S BREATHING ZONE AN D GENERAL AREA. USE EXHAUST SYSTEM
    TO CLEAR WELDING FUMES.
Other Precautions:FOR ADDITIONAL SAFETY INFORMATION ON WELDING AND
    CUTTING, SEE AMERICAN STD. Z49-1-1983, SAFETY IN WELDING AND
    CUTTING, AND THE WELDING HANDBOOK, VOL. 1 CHAPTER 9, SAFE PRACTICES
    IN WELDING/CUTTING. AV AILABLE FROM AMERICAN WELDING SOCIETY, INC.

    305-443-9353.

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:USE RESPIRABLE FUMES RESPIRATORY OR AIR SUPPLIED
    RESPIRATOR WHEN WELDING IN A CONFINED SPACE OR WHERE LOCAL EXHAUST
    OR VENTILATION DOES NOT KEEP EXPOSURE BELOW THE RECOMMENDED
    EXPOSURE LIMIT.
Ventilation:USE ENOUGH VENTILATION, LOCAL EXHAUST AT THE ARC, OR BOTH,
    TO KEEP FUMES AND GASES FROM THE WORKER'S BREATHING ZONE AND
    GENERAL AREA.
Protective Gloves:AT A MINIMUM WELDER'S GLOVES
Eye Protection:HELMET OR USE FACE SHIELD WITH FILTER LENS.
Other Protective Equipment:WEAR HAND, HEAD, BODY PROTECTION TO PREVENT
    INJURY FROM RADIATION, SPARKS AND ELECTRICAL SHOCK. SEE ANZI
    A49-1.THIS INCLUDES PROTECTIVE FACE SHIELD, WELDER'S GLOVES, AND
    MAY INCLUDE (CONTD. SEE BELOW)
Work Hygienic Practices:(CONTD FROM ABOVE) ARM PROTECTORS, APRONS,
    HATS, SHOULDER PROTECTION, AS WELL AS DARK SUBSTANTIAL CLOTHING.
    TRAIN WELDER NOT TO TOUCH LIVE ELECTRICAL PARTS AND TO INSULATE
    HIMSELF FROM WORK AND GROUND.
Supplemental Safety and Health
TRAIN WELDER TO KEEP HIS HEAD OUT OF THE FUMES. PROVIDE PROTECTIVE
    SCREENS AND FLASH GOGGLES, IF NECESSARY TO SHIELD OTHERS. FILTER
    LENS SELECTION;  AS A RULE OF THUMB, START WITH A SHADE THAT IS TOO
     DARK TO SEE THE WELD ZONE. THEN GO THE NEXT LIGHTER SHADE WHICH
    GIVES SUFFICIENT VIEW OF THE WELD ZONE.

==================  Physical/Chemical Properties  ==================

HCC:N1
Appearance and Odor:EACH ELECTRODE: METAL ROD; 0.156 IN. DIAMETER BY 14
    INCHES LONG

=================  Stability and Reactivity Data  =================

Stability Indicator/Materials to Avoid:YES
NONE.
Stability Condition to Avoid:NONE: UNLESS OTHERWISE SPECIFIED.
Hazardous Decomposition Products:COMPOSITION  AND QUALITY OF WELDING
    FUMES AND GASES ARE DEPENDENT ON THE METAL WELDED, THE PROCESS,
    PROCEDURE, AND ELECTRODES USED, COATINGS ON WELDED METAL (PAINT,
    PLATING, GALVANIZING), (CONTD. BELOW)

===================  Toxicological Information	===================

Toxicological Information:HAZARDOUS DECOMPOSITION PRODUCTS: THE
    COMPOSITION AND QUALITY OF WELDING FUMES AND GASES ARE DEPENDENT
    UPON THE METAL BEING WELDED, THE PROCESS, PROCEDURE, AND ELECTRODES
    USED. OTHER CONDITIONS WHICH  ALSO INFLUENCE THE COMPOSITION AND
    QUALITY OF THE FUMES AND GASES TO WHICH WORKERS MAY BE EXPOSED
    INCLUDE: COATINGS ON THE METAL BEING WELDED (SUCH AS PAINT,
    PLATING, OR GALVANIZING), THE NUMBER OF WE LDERS, THE VOLUME OF THE
    WORK AREA, THE QUALITY AND AMOUNT OF VENTILATION, POSITION OF
    WELDER'S HEAD WITH RESPECT TO THE FUME PLUME, AS WELL AS THE
    PRESENCE OF CONTAMINANTS IN THE ATMOSPHERE (CHLORINA TED (CONTD.
    SEE ECOLOGICAL)

=====================  Ecological Information  =====================

Ecological:(CONTD. FROM "TOXICOLOGICAL") HYDROCARBON VAPORS FROM
    CLEANING AND DEGREASING ACTIVITIES). WHEN THE ELECTRODE IS
    CONSUMED, THE FUMES AND GAS DECOMPOSITION PRODUCTS, ARE NOT THE
    INGREDIENTS IN THE ELEC TRODE, BUT ARE COMPOUNDS GENERATED FROM THE
    WELDING OPERATION FUME AND GAS DECOMPOSITION PRODUCTS. THE
    CONCENTRATION OF A GIVEN FUME OR GAS COMPONENT MAY DECREASE OR
    INCREASE BY MANY TIMES THE ORIGINA L CONCENTRATION IN THE
    ELECTRODE. ALSO, NEW COMPOUNDS NOT IN THE ELECTRODE MAY FORM.
    DECOMPOSITION PRODUCTS OF NORMAL OPERATION INCLUDE THOSE
    ORIGINATING FROM THE VOLITION, REACTION, OR OXIDATION OF T HE
    ELECTRODE PLUS (CONTD SEE "SARA")

====================  Disposal Considerations  ====================

Waste Disposal Methods: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, AN D LOCAL REGULATIONS.

=====================  Regulatory Information  =====================

SARA Title III Information:(CONTD. FROM "ECOLOGICAL") THOSE FROM THE
    BASE METAL AND COATING, ETC. REASONABLE EXPECTED FUME CONSTITUENTS
    OF THESE PRODUCTS COULD INCLUDE PRIMARILY OXIDES OF IRON;
    SECONDARILY COMPLEX OXIDES OF MAN GANESE, SILICON, NICKEL,
    CHROMIUM, MOLYBDENUM AND VANADIUM. THE PRESENT OSHA PERMISSIBLE
    EXPOSURE LIMITS FOR HEXAVALENT CHROMIUM IS 0.05 MG/M3 AND FOR
    NICKEL  1 MG/M3, WHICH WILL RESULT IN A SIGNIFICA NT REDUCTION FROM
    THE 5 MG/M3 GENERAL FUME LEVEL. GASEOUS REACTION PRODUCTS MAY
    INCLUDE CARBON MONOXIDE AND CARBON DIOXIDE. OZONE AND NITROGEN
    OXIDES MAY BE FORMED BY THE RADIATION FROM THE ARC, IN AD DITION TO
    THE (CONTD. SEE BELOW)
Federal Regulatory Information:(CONTD. FROM ABOVE)SHIELDING GASES LIKE
    ARGON AND HELIUM WHENEVER THEY ARE EMPLOYED. ONE RECOMMENDED WAY TO
    DETERMINE THE COMPOSITION AND QUANTITY OF FUMES AND GASES TO WHICH
    WORKERS ARE EXPOSED IS TO  TAKE AN AIR SAMPLE FROM INSIDE THE
    WELDER'S HELMET IF WORN OR IN THE WORKER'S BREATHING ZONE. SEE AWS
    F1.1 AND AWS F1.2 - 1985, AVAILABLE FROM THE AMERICAN WELDING
    SOCIETY. SEE AWS PUBLICATION: "FUME S AND GASES IN THE WELDING
    ENVIRONMENT".
