| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | If inhaled or swallowed, this compound may cause fluoride poisoning by reducing cellular calcium function. Early symptoms include nausea, vomiting, diarrhea and weakness. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin, eyes. |
| Eye Contact: | Causes burns and serious eye damage. Effects may not immediately appear. |
| Skin Contact: | Causes burning with redness and pain. Soluble fluoride may be corrosive. Effects may not immediately appear. |
| Inhalation: | Inhalation of dust may cause chemical burns to the respiratory tract, causing coughing, sore throat, and labored breathing. |
| Ingestion: | May cause salivation, nausea, vomiting, diarrhea, and abdominal pain. |
| Acute Health Effects: | Fluoride poisoning may cause nausea, vomiting, diarrhea, weakness, coma and respiratory paralysis. Causes burns to eyes, ulceration of skin. |
| Chronic Health Effects: | Prolonged exposure to soluble fluorine compounds can cause deterioration of bone and tooth structure, and kidney damage. Although less toxic than Chromium (VI), some animal studies show chromium (III) to act as a mutagen and tumorigen. |
| NTP: | Yes |
| IARC: | Yes |
| 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. |
