| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Thallium compounds, especially if water soluble, are highly poisonous by ingestion. Thallium compounds have been used as a rat poison. |
| Primary Routes of Exposure: | Ingestion |
| Eye Contact: | May cause slight to mild irritation of the eyes. |
| Skin Contact: | May cause slight to mild irritation of the skin. Harmful in contact with skin. |
| Inhalation: | May be irritating to the nose, mucous membranes and respiratory tract. Thallium poisoning may occur. |
| Ingestion: | Ingestion may result in swelling of the feet and legs, mental confusion, paralysis and angina-like pains. Very toxic if swallowed. |
| Acute Health Effects: | Acute poisoning, after 1-10 days, results in pain of the extremities, fever, difficulty in moving, vomiting, followed by jumbled speech, tremors, convulsions, kidney failure, and pulmonary edema. |
| Chronic Health 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. |
