SECTION 3: Hazards Identification
Emergency Overview: Dust may be irritating to the respiratory tract, skin and eyes. May be harmful if swallowed. Chronic exposure may lead to a skin discoloration.
Primary Routes of Exposure: Contact with skin and eyes. Inhalation of dust.
Eye Contact: May be a mild irritant to the eyes.
Skin Contact: May cause slight to mild irritation of the skin. Contact with the skin can lead to formation of dark blotches (silver staining)
Inhalation: Inhalation of dust can lead to irritation of the respiratory tract.
Ingestion: Ingestion may lead to dizziness, abdominal cramps, vomiting, bloody diarrhea, weakness, and convulsions.
Acute Health Effects: May be irritating to skin, eyes and respiratory tract.
Chronic Health Effects: Long term exposure to silver and silver salts can lead to the condition known as argyria - a general gray pigmentation of the skin and mucous membranes.
NTP: No
IARC: No
OSHA: No
SECTION 4: First Aid Measures
Eye Exposure: Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure: Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation: Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
Ingestion: Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.
SECTION 5: Fire Fighting Measures
Flash Point: not applicable
Autoignition Temperature: none
Explosion Limits: none
Extinguishing Medium: none required
Special Fire Fighting Procedures: If involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing.
Hazardous Combustion and Decomposion Products: none
Unusual Fire or Explosion Hazards: No unusual fire or explosion hazards.
SECTION 6: Accidental Release Measures
Spill and Leak Procedures: To avoid raising dust, small spills may be mixed with diatomaceous earth, sand, vermiculite or other suitable inert material and swept up.
SECTION 7: Handling and Storage
Handling and Storage: Store solid in a tightly sealed container away from light.
SECTION 8: Exposure Controls and Personal Protection
