May be harmful if swallowed. Prolonged exposure may produce a Emergency Overview: mild toxic syndrome known as iodism. 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:Large oral doses may cause irritation to the gastrointestinal tract Acute Health Affects:Irritating to skin, eyes and respiratory tract. Chronic ingestion of iodides may produce iodism. Symptoms include skin rash, running nose, headache and Chronic Health Affects: irritation of mucous membranes. NTP:No IARC:No OSHA:No SECTION 4: First Aid Measures Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need Eye Exposure: assistance in keeping their eye lids open. Get immediate medical attention. Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if Skin Exposure: irritation persists. Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty Inhalation: in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce Ingestion: vomiting only if directed by medical personnel.
