| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Hydrofluoric acid may form upon contact with moisture, causing delayed, deep, slow healing, painful burns. If inhaled or swallowed, this compound may cause fluoride poisoning. |
| Primary Routes of Exposure: | Contact with skin and eyes. Inhalation of dust. |
| Eye Contact: | Causes burns to the eyes. May cause blindness. |
| Skin Contact: | Prolonged contact with skin causes delayed deep slow healing painful burns. |
| Inhalation: | (As dust) Causes chemical burns to the respiratory tract. |
| Ingestion: | If ingested, severe burns to the gastrointestinal tract may occur. |
| Acute Health Effects: | Burns to eyes and skin. Dust: Fluoride poisoning may cause nausea, vomiting, diarrhea, weakness, coma, respiratory failure and cardiovascular collapse. |
| Chronic Health Effects: | Prolonged exposure to hydrolysable fluorine compounds can cause deterioration of bone and tooth structure. |
| 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. Apply calcium gluconate jelly or water soluble calcium salts as antidote. Seek medical assistance. |
| 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. |

| Autoignition Temperature: | none |
| Explosion Limits: | none |
| Extinguishing Medium: | None. Material is non-flammable. |
| Special Fire Fighting Procedures: | If this product is involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing. |
| Hazardous Combustion and Decomposion Products: | If involved in a fire this material may emit corrosive fumes of hydrofluoric acid. |
| Unusual Fire or Explosion Hazards: | No unusual fire or explosion hazards. |
| SECTION 6: Accidental Release Measures | |
|---|---|
| Spill and Leak Procedures: | Small spills can be mixed with powdered sodium bicarbonate, lime, or calcium carbonate and swept up. Avoid raising dust. Spillage in areas not adequately ventilated may require an evacuation of area. Emergency response teams will require self-contained breathing apparatus. |
| SECTION 7: Handling and Storage | |
|---|---|
| Handling and Storage: | Store solid in a tightly sealed container away from moisture. Handle in a fume hood under a dry atmosphere of air or nitrogen. Prolonged exposure to the atmosphere may degrade the product. |
| SECTION 8: Exposure Controls and Personal Protection | |
|---|---|
| Eye Protection: | Always wear approved safety glasses when handling a chemical substance in the laboratory. |
| Skin Protection: | Wear protective clothing and gloves. Consult with glove manufacturer to determine the proper type of glove. |
| Ventilation: | The solid may form corrosive vapors. It should be handled in an efficient fume hood. |
| Respirator: | If in form of fine dust and ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134. |
| Additional Protection: | No additional protection required. |
