SECTION 3: Hazards Identification
Emergency Overview: Irritating to eyes, skin and respiratory tract. May be harmful if swallowed
Primary Routes of Exposure: Inhalation, skin, eyes
Eye Contact: Causes slight to mild irritation of the eyes.
Skin Contact: Causes slight to mild irritation of the skin. Contact with the skin can lead to formation of dark blotches (silver staining)
Inhalation: Irritating to the nose, mucous membranes and respiratory tract.
Ingestion: Ingestion may lead to dizziness, abdominal cramps, vomiting, bloody diarrhea, weakness, and convulsions.
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.
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
