Potential health effects (overview):
The material in either solid or alloy form is generally not considered
hazardous. However, if the process involves grinding, melting, cutting,
or any other process that causes a release of fumes, hazardous levels
of airborne particulates could be generated.
Eye: May cause eye irritation
Skin: May cause skin irritation or discoloration
Ingestion: May cause irritation of the digestive tract. Effects may be cumulative.
Inhalation: May cause respiratory tract irritation. Inhalation of fumes may
cause metal fume fever, which is characterized by flue-like symptoms with metallic
taste, fever, chills, cough, weakness, chest pain, muscle pain and increased white
blood cell count.
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.
Chronic: Chronic inhalation or ingestion of silver salts may cause argyria
characterized by a permanent blue-gray discoloration of the eyes, skin, mucous
membranes and internal
organs.
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 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.
First Aid for Ingestion:
Do not induce vomiting. If conscious and alert, rinse out mouth
and drink 2-4 cupfuls of milk or water. Obtain medical assistance
at once.
Flash Point.................... Not Applicable Autoignition Temperature....... Not Applicable Flammable Limits in Air........ Flammable limit in air, % by vol. LEL (Lower Explosive Limit) : Not Applicable UEL (Upper Explosive Limit) : Not Applicable Fire Extinguishing Media: This material is non-combustible. Use appropriate extinguishing agent for surrounding fires. Do not use water to extinguish fires around operations involving molten metal, due to the potential for a steam explosion. Firefighting Procedure: 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. Fire and explosion hazards. This is a stable material and will not burn or ignite. May decompose upon heating to produce corrosive and/or toxic fumes.
Spill Response: Because of its high intrinsic value, and also because it is a non-renewable resource, this material should be reclaimed when possible. Spills/Leaks: Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately. Avoid generating dusty conditions. Provide ventillation; wear proper personal protective equipment. Disposal considerations: Because of its high intrinsic value, and also because it is a non-renewable resource, this material should be reclaimed when possible. When reclaiming is not feasible and disposal the only alternative, then it should be done in accordance with all applicable federal, state, and local regulations.
In solid form this material poses no special problems. Store metal in a dry area. Do not store adjacent to acids. Wash hands thoroughly after using. Wash hands before eating. Avoid contact with eyes, skin and clothing. Avoid inhalation and ingestion.
Eye Protection Requirements:
Safety glasses are recommended.
Skin Protection Requirements:
Protective gloves are recommended, to prevent skin exposure.
Respiratory Protection:
Use an appropriate NIOSH approved respirator if airborne
dust concentrations exceed the PEL or TLV.
Other protective equipment:
Eye wash fountain should be readily available in areas of
use of handling.
Exposure Limits:
Chemical Name ACGIH NIOSH OSHA-Final PELS
Silver 0.01 mg/m3 TWA(dust) 0.01 mg/m3 TWA 10 mg/m3 IDHL (dust)
OSHA
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 employee breathing zone and work area.

No hazardous ingredients in this material. RTECS#: VW3500000 LD50/LC50 Information: Not available Carcinogenicity: Not listed by ACGIH, IARC, NTP, or CA Prop 65 IARC: Group 4 Teratogenicity: Not available Reproductive Effects: Not available Neurotoxicity: Not available Mutagenicity: Not available
Environmental: When used and/or disposed of as indicated, no adverse
environmental effects are foreseen.
Mobility: Non-volatile/Insoluble in water.
Degradability: Not biodegradeable
Product and packaging must be disposed of in accordance with local and national regulations. Because it is a non-renewable resource and has economic value, waste material is usually a candidate for recycling. Unused product may be returned for reclamation provided it has been purchased from SPI Supplies. Contact SPI Supplies sending information about lot number and approximate time of purchase.
