SECTION 3: Hazards Identification
Emergency Overview: Irritating to the skin, eyes, and respiratory tract. May be harmful if swallowed. Prolonged exposure to iodide salts may produce a mild toxic syndrome.
Primary Routes of Exposure: Contact with skin and eyes. Inhalation of dust.
Eye Contact: Contact with eyes causes irritation. May cause redness and pain.
Skin Contact: Causes irritation to skin. Symptoms include redness, itching, and pain, pimples, boils, hives and blisters.
Inhalation: Causes irritation to the respiratory tract. Symptoms may include coughing and shortness of breath.
Ingestion: Ingestion of copper compounds may lead to vomiting, exhaustion, anemia, convulsions and coma.
Acute Health Effects: Irritating to skin, eyes and respiratory tract. Inhalation of copper dusts may cause chills, muscle ache, nausea, fever and dry throat.
Chronic Health Effects: Chronic ingestion of iodides may produce iodism. Symptoms include skin rash, running nose, headache and irritation of 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.
