Section 3: Hazard Identification
EMERGENCY OVERVIEW: The alloys as sold in solid form are generally not considered hazardous. However, if the process
involves grinding, melting, cutting or any other process that causes a release of dust or fumes, hazardous levels of airborne
particulates could be generated.
PRIMARY ROUTES OF ENTRY: Inhalation, Skin contact.. TARGET ORGANS: Skin, Respiratory tract
HUMAN EFFECTS AND SYMPTOMS OF OVEREXPOSURE: Listed below are certain potential health hazards, which apply
to the hazardous ingredients, found in the subject alloy(s).
SILVER: Excessive or chronic exposure, skin contact or inhalation, may lead to a condition called Argyrosis - a local or
generalized discoloration of the eyes, skin and mucous membrane, where gray/blue patches of pigmentation are
formed.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Individuals who may have had allergic reactions to metals
or sensitivity, may encounter skin rash or dermatitis, if skin contact with this product occurs. Persons with impaired pulmonary
functions, may incur further impairment if dust or fumes are inhaled
CARCINOGENIC REFERENCES: Silver is a questionable carcinogen with experimental tumorigenic data
Section 4: First Aid Meas ures
FIRST AID FOR EYES: Dust or powder should be flushed from the eyes with running water for 15 minutes. If irritation
persists obtain medical assistance.
FIRST AID FOR SKIN: Skin cuts and abrasions can be treated by standard first aid. Skin contamination with dust or powder
can be removed with soap and water. If irritation persists obtain medical assistance.
FIRST AID FOR INGESTION: Obtain medical assistance at once.

Silver 鈥? Core Material
FIRST AID FOR INHALATION: Breathing difficulty, caused by inhalation of dust or fume requires removal to fresh air.
If breathing has stopped perform artificial respiration and seek medical assistance at once.
Section 5: Fire Fighting Measures
FLASH POINT: Non-flammable as a solid
EXTINGUISHING MEDIA: This material is non-combustible, in solid form. Use appropriate extinguishing agent for surrounding
fires. Do not use water to extinguish fires around operations involving mo lten metal, due to the potential for steam explosion.
SPECIAL FIRE FIGHTING PROCEDURES: Self-contained breathing apparatus should be worn when fighting metal dust
fires. High levels of dust or fine particles in the air may ignite or explode.
Section 6: Accidental Release Measures
SPILL OR LEAK PROCEDURES: In solid form this material poses no special clean-up problems. Use normal clean up
procedures; wet sweeping or HEPA vacuum, for clean up of dust or powder. Do not use compressed air for cleaning.
Section 7: Storage and Handling
In solid form this material poses no special problems. Store metal in a dry area. Do not store adjacent to acids.
Section 8: Exposure Control/Personal Protection
EYE PROTECTION REQUIREMENTS: Safety glasses are recommended.
SKIN PROTECTION REQUIREMENTS: Protective gloves are recommended, to prevent mechanical irritation.
RESPIRATORY PROTECTION: Not normally required. Use an appropriate NIOSH approved respirator if airborne dust
concentration exceed the OSHA, PEL or ACGIH , TLV
OTHER PROTECTIVE EQUIPMENT: Eye wash fountain should be readily available in areas of use or handling.
EXPOSURE LIMITS: Not established for product as whole. Refer to Section 2.
VENTILATION REQUIREMENTS:
LOCAL EXHAUST: Recommended, when cutting, grinding or melting or any other operation where dust or fumes are created
GENERAL: Recommended
ENVIRONMENTAL SURVEILLANCE: If the operation generates dust or fumes, exposure to airborne materials should be
determined by having air samples taken in the employees breathing zone and work area.

Section 10: Reactivity
STABILITY: This is a stable material. HAZARDOUS POLYMERIZATION: Will not occur.
INCOMPATIBILITIES: Acetylene, Ammonia, Acids and Strong Oxidizers.
DECOMPOSITION PRODUCTS: None under proper usage conditions.
CONDITIONS TO AVOID: Conditions which create dust or fumes.
Section 11: Toxicological Information
There is no information on the toxicity of this alloy. Under normal use of the solid form of this material there are few health hazards.
Welding, cutting grinding or any process creating dust, fume or oxide may cause hazardous levels of certain elements, as addressed
in Section 2.
Section 12: Ecological Information
In solid form this material poses no special environmental problems. Metal powder or dust may have significant impact on air and
water quality. Emissions, spills and releases to the environment should be controlled immediately.
Section 13: Disposal Considerations
Because of its high intrinsic value this material should be reclaimed. Dispose of in accordance with all applicable Federal, State and
Local Regulations.
