SECTION 3: Hazards Identification
Emergency Overview: Irritating to skin, eyes and respiratory tract. May affect thyroid and kidney functions
Primary Routes of Exposure: Ingestion
Eye Contact: Causes moderate irritation of the eyes.
Skin Contact: Causes moderate irritation of the skin. Contact with the skin can lead to formation of dark blotches (silver staining)
Inhalation: May cause difficulty in breathing and irritate mucous membranes and respiratory tract.
Ingestion: No specific information is available on the physiological effects of ingestion. May cause gastrointestinal irritation, nausea, and vomiting.
Acute Health Effects: 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. Perchlorates reversibly inhibit thyroid iodine uptake. Kidney function may be affected.
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: no data
Autoignition Temperature: no data
Explosion Limits: no data
Extinguishing Medium: Water spray
Special Fire Fighting Procedures: Spray closed containers with water until fire is out. Avoid contact with combustible material. Fire fighters should be equipped with a NIOSH approved self-contained breathing apparatus.
Hazardous Combustion and Decomposion Products: If involved in a fire this material may emit corrosive hydrogen chloride fumes.
Unusual Fire or Explosion Hazards: Releases oxygen on heating. May decompose explosively under fire fighting conditions. Do not mix with combustibles.
SECTION 6: Accidental Release Measures
Spill and Leak Procedures: Do not mix spilled powder with any combustible materials, such as sawdust. Sweep up the solid and dilute with water.
SECTION 7: Handling and Storage
Handling and Storage: Store in a tightly sealed container in a cool dry place away from combustible and flammable materials. If the container is left open, salt may adsorb moisture from the atmosphere
SECTION 8: Exposure Controls and Personal Protection
Eye Protection: Always wear approved safety glasses when handling a chemical substance in the laboratory.
Skin Protection: Wear protective clothing and gloves
Ventilation: If possible, handle the material in an efficient fume hood.
Respirator: If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134.
Additional Protection: No additional protection required.
