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

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 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.

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.

HCC:N1
Appearance and Odor:ELECTRODE: METAL 0.035 IN. DIAMETER; ROLL.

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)

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.

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:(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")

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".
