Routes of Entry: Inhalation:YES Skin:YES Ingestion:NO
Health Hazards Acute and Chronic:IMPORTANT: WELDING ELECTRODES ARE A
NON-HAZARDOUS SOLID AT AMBIENT TEMPERATURES. THE FUMES AND GASES
PRODUCED WHILE WELDING DURING NORMAL USE FOLLOWS:WELDING GENERATES
FUMES, GASES, AND ELECTROMAGNETI C RADIATION WITH KNOWN ADVERSE
HEALTH EFFECTS. COMPOSITION OF WELDING EMISSIONS VARIES
SUBSTANTIALLY WITH THE WELDING PROCESS. EXPOSURE: ACTUAL EXPOSURE
SHOULD BE MONITORED IN THE OPERATOR'S BREATHING ZONE. POSSIBLE
EFFECTS OF EXPOSURE: SHORT TERM EXPOSURE TO WELDING FUME MAY RESULT
IN DISCOMFORT, DIZZINESS, NAUSEA AND DRYNESS OR IRRITATION OF
THROAT. LONG TERM EXPOSURE TO WELDING FUME, GASES, OR DUST MAY
(CONTD. SEE "TOXICOLOGICAL")
Explanation of Carcinogenicity:INGREDIENTS:SILVER (SOLUBLE COMPOUNDS),
LEAD, AND WELDING FUMES ARE IDENTIFIED AS SUSPECTED OR CONFIRMED
CARCINOGENS. NICKEL AND CHROMIUM SHOULD CONSIDERED POSSIBLE
CARCINOGENS PER OSHA 29 CFR 1910.1 200.
Effects of Overexposure:ROUTES OF ENTRY: (1) INHALATION OF FUME. (2)
BURNS FROM ELECTROMAGNETIC RADIATION. SIGNS AND SYMPTOMS OF
OVEREXPOSURE TO WELDING FUMES: INHALATION: DISCOMFORT, DIZZINESS,
NAUSEA, AND DRYNESS OR IRRITA TION OF THROAT. LONG TERM EXPOSURE TO
WELDING FUME, GASES, OR DUST: PULMONARY IRRITATION OR
PNEUMOCONIOSIS. LONG TERM EXPOSURE TO IRON FUME MAY PRODUCE
SIDEROSIS, WHICH IS GENERALLY REGARDED AS BENIGN . SKIN: BURNS.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH IMPAIRED PULMONARY
FUNCTION OR ILLNESS MAY HAVE SYMPTOMS EXACERBATED BY IRRITANTS
CONTAINED IN WELDING FUMES.

First Aid:REMOVE FROM DUST OR FUME EXPOSURE. IF BREATHING HAS STOPPED
PERFORM ARTIFICIAL RESPIRATION. SUMMON MEDICAL AID IMMEDIATELY.
READ AND UNDERSTAND THE MANUFACTURER'S INSTRUCTIONS AND THE
PRECAUTIONARY LA BEL ON THE PRODUCT. SEE AMERICAN NATIONAL STANDARD
Z49.1, SAFETY IN WELDING AND CUTTING PUBLISHED BY THE AMERICAN
WELDING SOCIETY, PO BOX 351040, MIAMI, FL 33135 AND OSHA

WASHINGTON DC 20402 FOR MORE DETAILED INFORMATION.

Flash Point:NONE
Extinguishing Media:THIS ALLOY IS NONCOMBUSTIBLE. USE EXTINGUISHING
MEDIA APPROPRIATE TO THE SURROUNDING FIRE.
Fire Fighting Procedures:IF THIS MATERIAL IS REDUCED TO POWDER FORM,
CAUTION MUST BE USED TO PREVENT FIRE OR EXPLOSION. TO EXTINGUISH A
METAL POWDER FIRE USE DRY SAND, DRY GRAPHITE OR OTHER CLASS "D"
FIRE EXTINGUISHING POWDER .
Unusual Fire/Explosion Hazard:NO UNUSUAL FIRE OR EXPLOSION HAZARDS ARE
ASSOCIATED WITH THIS MATERIAL.

Spill Release Procedures:NOT APPLICABLE.

Handling and Storage Precautions:WEAR HEAD AND BODY PROTECTION WHICH
HELPS TO PREVENT INJURY FROM RADIATION, SPARKS, FLAME, AND
ELECTRICAL SHOCK. TRAIN EMPLOYEE NOT TO TOUCH LIVE ELECTRICAL PARTS
AND TO INSULATE HIMSELF FROM WORK AND GROUND. WELDERS SHOULD NOT
WEAR SHORT SLEEVE SHIRTS, SHORT PANTS, OR CUTOFFS.
Other Precautions:USE EXHAUST TO CLEAR WELDING FUMES. MAKE SURE INHALED
AIR DOES NOT CONTAIN FUMES ABOVE PERMISSIBLE LEVELS. FOR OTHER
SAFETY INFORMATION ON WELDING AND CUTTING, SEE AMERICAN STANDARD
Z49.1-1980. SAFE TY IN WELDING AND CUTTING, AND WELDING HANDBOOK,
VOL. 1, CHAPTER 9, SAFE PRACTICES IN (CONTD. SEE "S TATE
REGULATORY")

Respiratory Protection:USE RESPIRABLE FUME RESPIRATOR OR AIR SUPPLIED
RESPIRATOR WHEN WELDING, BRAZING OR SOLDERING IN CONFINED SPACE OR
WHERE LOCAL EXHAUST OR VENTILATION DOES NOT KEEP EXPOSURE BELOW
PEL, TLV OR STEL. TRAI N THE EMPLOYEE TO KEEP HIS HEAD OUT OF THE
FUMES. SEE ANSI/ASC Z490 1 SECTION 5.
Ventilation:USE ENOUGH VENTILATION, LOCAL EXHAUST AT THE ARC (OR
FLAME), OR BOTH, TO KEEP THE FUMES AND GASES BELOW PEL'S, TLV'S OR
STEL'S IN THE WORKERS BREATHING ZONE.
Protective Gloves:WELDER'S GLOVES.
Eye Protection:WEAR HELMET OR USE FACE SHIELD WITH FILTER LENS OF
APPROPRIATE SHADE NUMBER.
Other Protective Equipment:WEAR HEAD AND BODY PROTECTION TO PREVENT
INJURY FROM RADIATION, SPARKS, ELECTRICAL SHOCK. SEE ANSI Z49.1
INCLUDES WELDER'S GLOVES, FACE SHIELD, ARM PROTECTORS, APRON, HATS,
SHOULDER PROTECTION.
Work Hygienic Practices:WEAR DARK AND SUBSTANTIAL CLOTHING.USE
APPROPRIATE 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.
Supplemental Safety and Health
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'S GLOVES AND A PROTECTIVE FACE SHIELD,
ANDMAY INCLUDE ARM PROTECTORS, APRONS, HATS, SHOULDER PROTECTION,
AS WELL AS DARK SUBSTANTIAL CLOTHING.

HCC:N1
Appearance and Odor:BARE PRODUCTS: SILVER OR COPPER. PASTE PRODUCTS:
GRAY OR COPPER IN APPEARANCE.

AVOID CONTACT WITH MINERAL ACIDS AND OXIDIZING AGENTS WHICH MAY
GENERATE HYDROGEN GAS; THE EVOLUTION OF HYDROGEN GAS; THE EVOLUTION
OF HYDROGEN MAY BE AN EXPLOSION HAZARD.
Stability Condition to Avoid:MOST WELDING, EVEN WITH PRIMITIVE
VENTILATION, DOES NOT PRODUCE EXPOSURES INSIDE THE WELDING HELMET
ABOVE 5MG/M3. THAT WHICH DOES, SHOULD BE CONTROLLED.
Hazardous Decomposition Products:VARIOUS ELEMENTAL METALS AND METAL
OXIDES MAY BE GENERATED FROM MELTING OR DROSS HANDLING OPERATIONS.

Waste Disposal Methods:PREVENT WASTE FROM CONTAMINATIING SURROUNDING
ENVIRONMENT. DISCARD ANY PRODUCT, RESIDUE, DISPOSABLE CONTAINER OR
LINER IN ANY ENVIRONMENTALLY ACCEPTABLE MANNER. IN FULL COMPLIANCE
WITH FEDERAL, STATE AND LOCAL REGULATIONS.

Toxicological Information:(CONTD. FROM "HEALTH HAZARDS") CONTRIBUTE TO
PULMONARY IRRITATION OR PNEUMOCONIOSIS. LONGG TERM EXPOSURE TO IRON
FUME MAY PRODUCE SIDEROSIS, WHICH IS GENERALLY REGARDED AS BENIGN.
NICKEL AND CHROMIUM SHOULD BE CONSIDERED A POSSIBLE CARCINOGEN PER
OSHA 29 CFR 1910.1200. CERTAIN NICKEL COMPOUNDS HAVE BEEN
IMPLICATED BASED ON EXPERIENCE IN SOME NICKEL REFINING OPERATIONS.
THE SPECIFIC COMPOUNDS, HOWE VER, HAVE NOT BEEN DETERMINED AND A
DIRECT ASSOCIATION BETWEEN NICKEL IN WELDING FUME AND CANCER HAS
NOT BEEN DETERMINED. SOME COMPOUNDS OF HEXAVALENT CHROMIUM HAVE
BEEN REPORTED (CONTD. SEE "ECOLOGI CAL").

ASSOCIATION HAS BEEN ESTABLISHED BETWEEN CHROMIUM IN WELDING FUME
AND DEVELOPMENT OF CANCER. EXPOSURE LIMITS SHOULD BE MAINTAINED
BELOW RECOMM ENDED LEVELS. EXPOSURE LIMITS: WELDING FUMES AND GASES
CANNOT BE CLASSIFIED SIMPLY. COMPOSITION AND QUANTITY OF BOTH ARE
DEPENDENT UPON METAL BEING WELDED, PROCESS, PROCEDURE AND
ELECTRODES USED. OTH ER CONDITIONS WHICH ALSO INFLUENCE COMPOSITION
AND QUANTITY OF FUMES AND GASES TO WHICH WORKERS MAY BE EXPOSED
INCLUDE: COATING ON METAL BEING WELDED (SUCH AS PAINT, PLATING OR

SARA Title III Information:(CONTD. FROM "ECOLOGICAL") GALVANIZING), THE
NUMBER OF WELDERS AND THE VOLUME OF WORK AREA, THE QUALITY AND
AMOUNT OF VENTILATION, THE POSITION OF 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 DEGREASING ACTIVITIES). WHEN ELECTRODE IS CONSUMED, THE FUME
AND GAS DECOMPOSITION PRODUCTS ARE DIFFERENT IN PERCENT AND FORM
FROM THE INGREDIENTS LISTED IN ELECTRODES AND FLUX. FUME AND GAS
DECOMPOSITION PRODUCTS, AND NOT INGREDIENTS IN ELECTRODE ARE
IMPORTANT. (CONTD. SEE "FEDERAL REGULAT ORY")
Federal Regulatory Information:(CONTD. FROM "SARA I I I") THE
CONCENTRATION OF A GIVEN FUME OR GAS COMPONENT MAY DECREASE OR
INCREASE BY MANY TIMES THE ORIGINAL CONCENTRATION IN THE ELECTRODE.
ALSO, NEW COMPOUND NOT IN THE ELECTROD ES MAY FORM. DECOMPOSITION
PRODUCTS OF NORMAL OPERSTION INCLUDE THOSE ORINGINATING FROM THE
VOLATILIZATION, REACTION, OR OXIDATION OF THE MATERIALS LISTED IN
THE ELECTRODES AND FLUX, PLUS THOSE FROM T HE BASE METAL AND
COATING, ETC., AS NOTE ABOVE. MOST WELDING, EVEN WITH PRIMITIVE
VENTILATION, DOES NOT PRODUCE EXPOSURES INSIDE THE WELDING HELMET
ABOVE 5 MG/M3. THAT WHICH DOES, SHOULD BE CONTROLLED.
