Routes of Entry: Inhalation:YES Skin:YES Ingestion:YES
Reports of Carcinogenicity:NTP:YES IARC:YES OSHA:YES
Health Hazards Acute and Chronic:ACUTE: INHALATION: PARTICULATES MAY
IRRITATE RESPIRATORY TRACT. INGESTION: LARGE DOSES MAY CAUSE
NAUSEA, VOMITING, AND DIARRHEA. SKIN CONTACT: MAY CAUSE IRRITATION
AND ALLERGIC DERMATITIS WHEN CHROM E, COBALT, COPPER AND NICKEL
ARE PRESENT. EYE CONTACT: METAL DUST, FUME, OR POWDER MAY INFLAME
THE CONJUCTIVA. AIRBORNE PARTICULATE (CHIPS, DUST, POWDER) IS
ALWAYS A POTENTIAL PROBLEM. CHRONIC: RESPIR ATORY DISEASES, FROM
SHORTNESS OF BREATH TO PERMANENT DISABILITY MAY BE CAUSED BY
EXCESSIVE EXPOSURE TO DUST OR FUMES OF COBALT, NICKEL. CNS
DEPRESSION MAY BE CAUSED BY EXCESSIVE MANGANESE EXPOSURE.
Explanation of Carcinogenicity:INSOLUBLE NICKEL AND HEXIVALENT CHROMIUM
COMPOUNDS HAVE BEEN LINKED TO NASAL, BRONCHIAL AND LUNG CANCERS.
CHROMIUM AND ITS COMPOUNDS, COBALT AND ITS COMPOUNDS, AND NICKEL
AND ITS COMPOUNDS ARE CLASSIF IED AS CARCINOGENS BY NTP AND/ OR
IARC. OSHA REQUIRES THAT WELDING FUMES BE CONSIDERED AS CARCINOGENS
BECAUSE THEY ARE SO CLASSFIED BY IARC.
Effects of Overexposure:INHALATION: RESPIRATORY TRACT IRRITATION,
SHORTNESS OF BREATHE, COUGH, BRONCHITIS, CHILLS, "METAL FUME
FEVER", ASTHMA-LIKE SYMPTOMS, LOSS OF LUNG FUNCTION, SENSITIZATION
OR HYPERSENSITIVITY AND FIBRO SIS, CENTRAL NERVOUS SYSTEM
DEPRESSION, NASAL, BRONCHIAL AND LUNG CANCERS. INGESTION: NAUSEA,
VOMITING, AND DIARHEA. SKIN: IRRITATION, ALLERGIC DERMATITIS. EYES:
INFLAMATION OF THE CONJUNCTIVA.
Medical Cond Aggravated by Exposure:PERSONS WITH PRIOR DISEASES
INVOLVING PULMONARY SYSTEM, ALLERGIES INVOLVING METALS, AND
NEUROLOGIC, CIRCULATORY, HEMATOLOGIC OR RENAL SYSTEMS PROBLEMS MAY
BE AT FURTHER RISK IF HANDLINGTHESE MATERIALS.

First Aid:INHALATION: MOVE TO FRESH AIR. IF BREATHING STOPPED, PERFORM
ARTIFICIAL RESPIRATION. GET MEDICAL ATTENTION. INGESTION: NEVER
GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON. CONTACT POISON
CONTROL CENTER. HAVE CONSCIOUS PERSON DRINK 1 TO 2 GLASSES OF
WATER. DO NOT INDUCE VOMITING UNLESS LARGE AMOUNTS INGESTED.GET
MEDICAL ATTENTION. SKIN: REMOVE CONTAMINATED CLOTHS. WASH EXPOSED
SKIN WITH SOAP AND WATER. IF IRRITATION OCCURS, GET MEDICAL
ATTENTION. EYES: FLUSH WITH WATER FOR 15 MINUTES. IF IRRITATION
OCCURS, GET MEDICAL ATTENTION.

Flash Point:NONE
Lower Limits:NONE
Upper Limits:NONE
Extinguishing Media:THESE ALLOYS IN SOLID WROUGHT FORM ARE
NONCOMBUSTIBLE. USE EXTINGUISHING MEDIA APPRAOPRATE TO THE
SURROUNDING FIRE.
Fire Fighting Procedures: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.
HAZARDOUS COMBUSTION PRODUCTS: VARIOUS METAL OXIDES, CARBON
DIOXIDE, CARBON MONOXIDE. FINE PARTICULATES DISPERSED IN AIR
PRESENT AN EXPLOSION HAZARD.

Spill Release Procedures:SOLID FORM MATERIAL IS NOT A PROBLEMS. POWDER
OR DUST FORM: DO NOT DRY SWEEP, CLEAN-UP SHOULD BE CONDUCTED WITH A
VACUUM SYSTEM WITH AN HEPA FILTRATION SYSTEM. MINIMIZE AIRBORNE
GENERATION OF POWDER O R DUST. AVOID CONTAMINATION OF AIR AND
WATER. PROTECT CLEANUP PERSONNELAGAINST DUST INHALATION AND SKIN OR
EYE CONTACT. USE NON SPARKING TOOLS. FOLLOW OSHA 29 CFR 1910 120,
EMERGENCY RESPONSE.

Handling and Storage Precautions:THIS PRODUCT MUST BE HANDLED ACCORDING
TO THE SIZE, SHAPE AND QUANTITY OF MATERIAL INVOLVED. POWDERS
SHOULD BE MOVED OR TRANSPORTED TO MINIMIZE SPILL OR RELEASE
POTENTIAL. AVOID DUST INHALATION AND EY E OR SKIN CONTACT. WEAR
PERSONAL PROTECTIVE EQUIPMENT TO PREVENT CONTACT WITH SKIN AND
EYES.
Other Precautions:IN SOLID FORM THIS MATERIAL POSES NO SPECIAL
PROBLEMS. STORE METAL POWDER IN A DRY AREA AWAY FORM HEAT, IGNITION
SOURCES AND INCOMPATIBLES. PRACTICE GOOD PERSONAL HYGIENE AFTER
HANDLING DUST OR POWDER FORMS OF THIS MATERIAL. ESPECIALLY BEFORE
EATING, DRINKING, SMOKING OR APPLYING COSMETICS.

Respiratory Protection:USE NIOSH APPROVED RESPIRATORS AS SPECIFIED BY
AN INDUSTRIAL HYGIENIST OR QUALIFIED SAFETY PROFESSIONAL. LUNG
FUNCTION TESTS ARE RECOMMENDED FOR USERS OF NEGATIVE PRESSURE
DEVICES. USE A FUME RESPIRAT OR OR AN AIR SUPPLIED RESPIRATOR WHERE
LOCAL EXHAUST OR VENTILATION DOES NOT KEEP EXPOSURE BELOW THE OSHA
LIMITS FOR AIR CONTAMINATION.
Ventilation:LOCAL EXHAUST VENTILATION SHOULD BE USED TO CONTROL
EXPOSURE TO AIRBORNE DUST AND FUME EMISSIONS NEAR THE SOURCE BELOW
THE EXPOSURE LIMITS.
Protective Gloves:WEAR GLOVES TO PREVENT METAL CUTS AND SKIN ABRASIONS.
Eye Protection:WEAR SAFETY GLASSES. CONTACT LENSES SHOULD NOT BE WORN
FOR METAL DUST HANDLING.
Other Protective Equipment:PROTECTIVE CLOTHING SUCH AS UNIFORMS,
DISPOSABLE COVERALLS, SAFETY SHOES, ETC. MAY BE REQUIRED DURING
METAL HANDLING OPERATIONS AS APPROPRIATE TO THE CIRCUMSTANCES OF
EXPOSURE.
Work Hygienic Practices:PRACTICE GOOD PERSONAL HYGIENE AFTER HANDLING
DUST OR POWDER FORMS OF THIS MATERIAL. ESPECIALLY BEFORE EATING,
DRINKING, SMOKING OR APPLYING COSMETICS.

Ecological:IN SOLID FORM ALLOYS POSE NO ENVIRONMENTAL PROBLEMS. METAL
POWDERS OR DUSTS MAY HAVE IMPACT ON AIR AND WATER QUALITY.
AIRBORNE EMISSIONS, SPILLS, RELEASES TO ENVIRONMENT (DISCHARGE TO
STREAMS, SEWER SYSTEMS, SURFACE SOIL, ETC.) SHOULD BE CONTROLLED.
ECOTOXICITY: FEW PLANTS ACCUMULATE COBALT AT GREATER THAN 100 PPM,
LEVEL AT WHICH SEVERE PHYTOXICITY WOULD OCCUR. THERE IS LITTLE
TENDENCY FOR CHR OMIUM I I I BIOACCUMULATION ALONG FOOD CHAIN.
MOLYDENUM: (FATHEAD MINNOW), LC50: 370 MG/L/96 HRS. TERRESTRIAL
PLANTS CANCONTAIN ENOUGH MOLYDENUM TO BE TOXIC TO ANIMALS BUT STILL
GROW NORMALLY. (CONTD. SEE " TRANSPORT")

Transport Information:DOT SHIPPING: NOT REGULATED. (CONTD. FROM
"ECOLOGICAL")ENVIRONMENTAL DEGRADATION IN WATER. COBALT IS ADSORBED
GREATLY TO HYDROLYSATE OR OXIDATE SEDIMENTS. IT MAY BE TAKEN INTO
SOLUTION IN SMALL AMOUNT S THROUGH BACTERIOLOGICAL ACTIVITY. IN
WATER, MOLYBDENUM WILL PRECIPTATE OUT WITH NATURAL CALCIUM. IN
WATER, CHROMIUM I I I OXIDE IS EXPECTED TO ENENTUALLY PRECIPITATE
TO SEDIMENTS. IN AIR, CHROMIUM I I I OXIDE IS PRIMARILY REMOVED BY
FALLOUT AND PRECIPITATION. SOILS WITH A HIGH CHROMIUM CONTENT
(,0.2% ARE EXPECTED TO BE INFERTILE. THE HALF-LIFE OF CHROMIUM IN
SOILS MAY BE SEVERAL YEARS.
