LD50 LC50 Mixture:ORAL (RAT) IS UNKNOWN.
Health Hazards Acute and Chronic:WELDING RODS ARE NON-HAZARDOUS SOLID
AT AMBIENT TEMPERATURES. WELDING GENERATES FUMES, GASES AND
ELECTROMAGNETIC RADITION WITH KNOWN ADVERSE HEALTH EFFECTS. THE
COMPOSITION OF WELDING EMISSIONS VARIES SUBSTANTIALLY WITH THE
WELDING PROCESS. SHORT TERM EXPOSURE TO WELDING FUMES MAY RESULT IN
DISCOMFORT, DIZZINESS, NAUSEA, AND DRYNESS OR IRRITATION OF THE
THROAT. LONG TERM EXPSOURE TO WELDING FUME, GASES, OR DUST MAY
CONTRIBUTE TO PULMONARY IRRITATION OR PNEUMOCONIOSIS. LONG TERM
EXPOSURE TO IRON FUME MAY PRODUCT SIDEROSIS, WHICH IS GENERALLY
REGARDED AS BENIGN.
Explanation of Carcinogenicity:NICKEL AND CADMIUM SHOULD BE CONSIDERED
POSSIBLE CARCINOGENS PER OSHA 29CFR 1910.1200. THE SPECIFIC
COMPOUNDS, HOWEVER HAVE NOT BEEN DETERMINED AND A DIRECT
ASSOCIATION BETWEEN NICKEL IN WELDING FUME AND CANCER HAS NOT BEEN
DEMONSTRATED. CADMIUM OXIDE FUME(S) ASSOCIATED WITH INDUSTRIAL
WELDING PROCESSES ARE SUSPECTED OF INDUCING CANCER.
Effects of Overexposure:EXPOSURE TO WELDING FUMES: DISCOMFORT,
DIZZINESS, NAUSEA, DRYNESS, IRRITATION, PNEUMOCONIOSIS, SIDEROSIS.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH IMPARED PULMONARY
FUNCTION OR ILLNESS MAY HAVE SYMPTOMS EXACERBATED BY IRRITANTS
CONTAINED IN WELDING FUME.

First Aid:MOVE FROM DUST OR FUME EXPOSURE. IF BREATHING HAS STOPPED
PERFOM ARTIFICIAN RESPIRATION. SUMMON MEDICAL AID IMMEDIATELY.

Flash Point:NONE
Autoignition Temp:Autoignition Temp Text:NONE
Lower Limits:NONE
Upper Limits: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.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

Handling and Storage Precautions:USE EXHAUST SYSTEM TO CLEAR WELDING
FUMES. MAKE SURE THAT INHALED AIR DOES NOT CONTAIN FUME CONSTUENTS
ABOVE PERMISSABLE LEVELS.
Other Precautions:ADDITIONAL SAFETY INFORMATION ON WELDING AND CUTTING
SEE AMERICAN STANDARD Z49.1-1980, SAFETY IN WELDING AND CUTTING,
AND WELDING HANDBOOK, VOLUME 1, CHAPTER 9, SAFE PRACTICES IN
WELDING AND CUTTING, AVAILABLE FROM AMERICAN WELDING SOCIETY, INC

305-443-9353.

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. MOS T WELDING, EVEN WITH PRIMITIVE VENTILATION,
DOES NOT PRODUCE EXPOSURES INSIDE THE WELDING HELMET ABOVE 5 MG/M3.
THAT WHICH DOES , SHOULD BE CONTROLLED.
Ventilation:USE ENOUGH VENTILATION, LOCAL EXHAUST AT THE ARC (OR
FLAME), OR BOTH, TO KEEP THE FUMES AND GASSES BELOW PEL'S, TLVS, OR
STELS IN THE WORKER'S BREATHING ZONE.
Protective Gloves:WELDER'S GLOVES
Eye Protection:WEAR HELMET OR FACESHEILD WITH FILTER LENS OF
APPROPRIATE SHADE.
Other Protective Equipment:PROVIDE PROTECTIVE SCREENS AND FLASH
GOGGLES, IF NECESSARY TO SHEILD OTHERS. WEAR HEAD AND BODY
PROTECTION WHICH HELP TO PREVENT INJURY FROM RADIATION, SPARKS,
FLAME AND ELECTRICAL SHOCK.
Work Hygienic Practices:TRAIN THE EMPLOYEE TO KEEP HIS HEAD OUT OF THE
FUMES. TRAIN THE EMPLOYEE NOT TO TOUCH LIVE ELECTRICAL PARTS AND TO
INSULATE HIMSELF FROM WORK AND GROUND.
Supplemental Safety and Health
BODY PROTECTION - ARM PROTECTORS, APRONS, HATS, SHOULDER PROTECTION, AS
WELL AS DARK SUBSTANTIAL CLOTHING. WELDERS SHOULD NOT WEAR SHORT
SLEEVE SHIRTS, SHORT PANTS, OR CUTOFFS.

HCC:N1
Evaporation Rate & Reference:NONE (METAL)
Solubility in Water:NO
Appearance and Odor:METAL WELDING RODS.

Stability Indicator/Materials to Avoid:YES
AVOID CONTACT WITH MINERAL ACIDS AND OXIDIZING AGENTS WHICH MAY
GENERATE HYDROGEN GAS, THE EVOLUTION OF HYDROGEN MAY BE AN
EXPLOSION HAZARD.
Hazardous Decomposition Products:VARIOUS METALS AND METAL OXIDES MAY BE
GENERATED FROM MELTING OR DROSS HANDLING OPERATIONS.

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, AND LOCAL REGULATIONS.
