Routes of Entry: Inhalation:YES Skin:YES Ingestion:YES
Reports of Carcinogenicity:NTP:YES IARC:YES OSHA:YES
Health Hazards Acute and Chronic:INHALATION: NUISANCE DUST MAY CAUSE
IRRITATION OF MUCOUS MEMBRANES/NOSE & THROAT, DIZZINESS, PULMONARY
IRRITANT, TIGHTNESS IN CHEST, METAL FUME FEVER, DRY THROAT,
COUGHING, LOW BACK PAIN, FATIGUE, & H EADACHE. SKIN: ALLERGIC
REACTIONS & DERMATITIS. INGESTION: METALLIC TASTE, NAUSEA, BURNS &
VOMITING. EYES: INJURY.
Explanation of Carcinogenicity:CHROMIUM & NICKEL ARE ANIMAL & HUMAN
CARCINOGENS.
Effects of Overexposure:INHALATION: POSSIBLE LUNG FIBROSIS, RESPIRATORY
HYPERSENSITIVITY/AFFECTS CENTRAL NERVOUS SYSTEM/MUSCULAR WEAKNESS,
TREMORS, SYMPTOMS SIMILAR TO PARKINSON'S DISEASE & SIDEROSIS
(BENIGN). ELECTRIC SHOCK CAN KILL. SHIELDING GASES CAN
DISPLACEBREATHING AIR & CAUSE ASPHYXIATION IN CONFINED WORK
SPACES/UNVENTILATED AREAS.
Medical Cond Aggravated by Exposure:RESPIRATORY ALLERGIC CONDITIONS.
SOME STUDIES SHOW A HIGHER LEVEL OF LUNG RELATED PROBLEMS AMONG
OLDER WORKERS WHO SMOKE THAN THOSE WHO DID NOT SMOKE.

First Aid:SKIN/EYES: FLUSH W/WATER FOR AT LEAST 15 MINS. INHALATION:
REMOVE VICTIM FROM THE WELDING AREA. IF VICTIM IS UNCONSCIOUS,
ADMINISTER OXYGEN. IF VICTIM IS NOT BREATHING, BEGIN RESUSCITATION.
INGESTION: EMPLOY THE FIRST AID TECHNIQUES RECOMMENDED BY THE
AMERICAN RED CROSS. OBTAIN MEDICAL ATTENTION IN ALL CASES.

Flash Point:NON-FLAMMABLE
Extinguishing Media:EXTINGUISHING MEDIA SUITABLE FOR SURROUNDING FIRE.
Fire Fighting Procedures:READ & UNDERSTAND ANSI Z49.1 "SAFETY IN
WELDING & CUTTING" & NFPA STANDARD 51B FOR FIRE PREVENTION IN
"CUTTING & WELDING PROCESSES" BEFORE USING THIS PRODUCT.
Unusual Fire/Explosion Hazard:PRODUCT IS NON-FLAMMABLE & NON-EXPLOSIVE,
AS SHIPPED. WELDING ARCS & SPARKS CAN IGNITE COMBUSTIBLES &
INITIATE FIRES & EXPLOSIONS.

Spill Release Procedures:IF THE FUMES ARE REMOVED BY FILTRATION/SOME
OTHER MEANS & AIR/GAS STREAM IS PUT BACK INTO THE ROOM, GASES MAY
BUILD UP TO TOXIC OR ASPHYXIATION LEVELS. GAS BUILD-UP SHOULD BE
MONITORED & IF EXCESSIVE SHOULD BE REMOVED/REDUCED TO SAFE LEVELS.

Handling and Storage Precautions:ARCS PRODUCE ULTRAVIOLET/INFRARED
RADIATION. SMAW ELECTRODES ARE METAL CORE RODS COATED W/FLUX. AVOID
PHYSICAL ACCIDENTS. READ LABELS.
Other Precautions:TRAIN WELDER TO AVOID ELECTRIC SHOCK BY MAINTAINING A
DRY WORK AREA, INSULATING FROM THE WORKPIECE & GROUND. DON'T TOUCH
LIVE ELECTRICAL PARTS. PREVENT INJURY FROM RADIATION/SPARKS/&
ELECTRIC SHOCK. K EEP HEAD OUT OF WELDING PLUME.

Respiratory Protection:USE A FUME RESPIRATOR OR AIR SUPPLIED RESPIRATOR
WHEN WELDING IN CONFINED SPACES/WHERE VENTILATION IS INADEQUATE IN
MAINTAINING EXPOSURE FUMES/GASES BY TAKI NG AN AIR SAMPLE FROM INSIDE HELMET.
Ventilation:USE ENOUGH VENTILATION, LOCAL EXHAUST AT THE ARC, OR BOTH
TO KEEP FUMES & GASES FROM THE WORKER'S BREATHING ZONE & Protective Gloves:DRY WELDER'S GLOVES
Eye Protection:FACE SHIELD W/PROTECTIVE LENSES
Other Protective Equipment:ARM/SHOULDER PROTECTORS, APRONS, HATS,
WELDER'S HELMET. SEE SUPP FOR LENSE SHADE RECOMMENDATIONS.
Work Hygienic Practices:INGESTION OF MATERIAL IS POSSIBLE VIA DIRTY
HAND CONTACT W/FOOD & MOUTH.
Supplemental Safety and Health
START W/LENSE SHADE THAT IS TOO DARK TO SEE THE WELD ZONE. THEN GO TO A
LIGHTER SHADE (LOWER NUMBER SHADE) WHICH GIVE SUFFICIENT VIEW OF
THE WELD ZONE. OTHER COATING INGREDIENTS (R 20% BY WT) SUCH AS
OXIDES/FLUORIDES OF AL, BA, CA, MG, K, NA, SR, & TI. WELDING
PRODUCES CHEMICALS KNOWN TO CAUSE CANCER BY THESTATE OF CA.

Spec Gravity:7-9

Appearance and Odor:BARE WIRE WELDING PRODUCTS ARE PRODUCED AS STRAIGHT
LENGTHS & COILED WIRES.

Stability Indicator/Materials to Avoid:YES
Hazardous Decomposition Products:CO/CO2/OZONE/OXIDES OF
NITROGEN/CHROMIUM II & III/NICKEL/COBALT/COPPER. WELDING
FUMES/GASES CANNOT BE EASILY CLASSIFIED.

Waste Disposal Methods:DISPOSE OF FUME, FLUX & WELD GRINDING RESIDUES
FROM THE WORK AREA, OR FROM FILTERS, IN ACCORDANCE W/LOCAL, STATE,
& FEDERAL REGULATIONS.
