| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | This material is a strong, corrosive fuming acid. The material is extremely corrosive to skin, eyes, mucous membranes and respiratory tract. Can release toxic fumes of hydrogen fluoride. |
| Primary Routes of Exposure: | Ingestion, inhalation, eyes and skin |
| Eye Contact: | Severe corrosive to the eyes. Exposure can lead to permanent eye damage. |
| Skin Contact: | Severe corrosive to skin. Material can be absorbed through the skin. Unless treated, contact can lead to deep and painful chemical burns. |
| Inhalation: | Material is a fuming liquid releasing toxic and corrosive vapors. Inhalation can lead to burning of the mucous membranes and lungs. |
| Ingestion: | Material is toxic and corrosive. Ingestion may be fatal unless immediate treatment is available. |
| Acute Health Effects: | Severe corrosive to eyes, skin, mucous membranes and respiratory tract. Ingestion may be fatal. |
| Chronic Health Effects: | The health effects resulting from prolonged exposure to this compound have not been thoroughly investigated. |
| 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. |
