| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Very toxic by inhalation and if swallowed. Irritating to skin, eyes and respiratory tract. Prolonged exposure to iodide salts may produce a mild toxic syndrome known as iodism. Danger of cumulative effects. |
| Primary Routes of Exposure: | Ingestion, inhalation. |
| Eye Contact: | Causes slight to mild irritation of the eyes. |
| Skin Contact: | Causes irritation to skin. Symptoms include redness, itching, and pain, pimples, boils, hives and blisters. |
| Inhalation: | Very toxic by inhalation. Irritating to the nose, mucous membranes and respiratory tract. |
| Ingestion: | Very toxic if swallowed. Ingestion of small amounts results in swelling of the feet and legs, mental confusion, pain, paralysis, and death. |
| Acute Health Effects: | Very toxic by inhalation and if swallowed. Acute poisoning results in swelling of the feet and legs, mental confusion, angina-like pains, paralysis, weakness, and death. |
| Chronic Health Effects: | Danger of cumulative effects. Prolonged exposure to thallium compounds causes discoloration of the hair, which later falls out, joint pain, loss of appetite, fatigue, severe pain in the legs, albuminuria, and optic neuritis. |
| 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. |
