| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | If inhaled or swallowed may cause fluoride poisoning. Early symptoms include nausea, diarrhea, weakness. Vapor of tetrahydrofuran can cause drowsiness and unconsciousness. |
| Primary Routes of Exposure: | Contact with skin and eyes and inhalation |
| Eye Contact: | Causes irritation. May cause serious damage. Effects may not immediately appear. |
| Skin Contact: | Causes defatting and irritation of the skin. Soluble fluoride may be corrosive to skin. Effects may not immediately appear. |
| Inhalation: | Irritating and harmful by inhalation. Inhalation may cause coughing, chest pains, nausea, dizziness, headache, drowsiness and unconsciousness. |
| Ingestion: | May cause salivation, nausea, vomiting, diarrhea, and abdominal pain. |
| Acute Health Effects: | Fluoride may cause nausea, vomiting, diarrhea, weakness, coma, and respiratory paralysis. THF is irritating to eyes and mucous membranes. May cause narcosis in high concentrations. |
| Chronic Health Effects: | Prolonged exposure to soluble fluorine compounds can cause deterioration of bone and tooth structure, and kidney damage. THF may cause liver and kidney damage. |
| 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. |
