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.
Primary routes of entry:
Inhalation, Skin contact
Human effects and symptoms of exposure:
Listed below are certain potential health hazards which apply to
the hazardous ingredients found in the subject alloy(s):
Gold: Generally None Toxic
Skin: May cause contact dermatitis.
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:
Material is not listed in the Annual Report on Carcinogens as
prepared by the National Toxicology Program (NTP), as well as
the International Agency for Research on Cancer (IARC),
Monograph Series or OSHA.
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:
Obtain medical assistance at once.
Flash Point.................... Non-flammable as a solid 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.
Spill Response: Because of its high intrinsic value, and also because it is a non-renewable resource, this material should be reclaimed when possible. 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.
Eye Protection Requirements:
Safety glasses are recommended.
Skin Protection Requirements:
Protective gloves are recommended, to prevent mechanical
irritation.
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 or handling.
Exposure Limits:
Not established for product as a whole. Refer to Section
02 above.
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.
