| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Thallium compounds are very toxic by inhalation and if swallowed. Irritating to skin, eyes and respiratory tract. Danger of cumulative effects. |
| Primary Routes of Exposure: | Ingestion, skin, inhalation of dust. |
| Eye Contact: | Causes severe irritation to the eyes. |
| Skin Contact: | Causes severe irritation of the skin causing redness, pain, itching, |
| Inhalation: | Very toxic by inhalation. Irritating to the nose, mucous membranes and respiratory tract. |
| Ingestion: | Very toxic if swallowed. Ingestion may result in swelling of the feet and legs, mental confusion, paralysis, angina-like pains. |
| Acute Health Effects: | Very toxic by inhalation and if swallowed. Acute poisoning results in pain of the extremities, fever, nausea and vomiting, jumbled speech, tremors, convulsions, kidney failure, and pulmonary edema. |
| Chronic Health Effects: | Danger of cumulative effects. Prolonged exposure to thallium compounds has been reported to lead to discoloration of the hair, which later falls out, joint pain, loss of appetite, fatigue, severe pain in the legs, albuminuria, and optic neuritis. Possible mutagen. |
| 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. |
