| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Material forms toxic and corrosive hydrofluoric acid with moisture. Causes delayed, deep, slow healing, painful burns. Toxic if swallowed. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin, eyes |
| Eye Contact: | Causes serious eye damage. Effects may not immediately appear. |
| Skin Contact: | Prolonged contact with skin can cause delayed deep slow healing painful burns. |
| Inhalation: | Dust or hydrofluoric acid fumes may cause severe irritation to the respiratory tract. |
| Ingestion: | Toxic if swallowed. May cause salivation, nausea, vomiting, diarrhea, and painful abdominal burns. |
| Acute Health Effects: | Fluoride poisoning may cause nausea, vomiting, diarrhea, weakness, coma, and respiratory paralysis. Hydrofluoric acid causes eye and skin burns and pulmonary edema. |
| Chronic Health Effects: | Prolonged exposure to soluble fluorine compounds can cause deterioration of bone and tooth structure, 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. 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. Do not induce vomiting. |
| SECTION 5: Fire Fighting Measures | |
|---|---|
| Flash Point: | not applicable |
| Autoignition Temperature: | none |
| Explosion Limits: | none |
| Extinguishing Medium: | none required |
| Special Fire Fighting Procedures: | If 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 toxic hydrofluoric acid fumes. |
| 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. 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 material in a tightly sealed bottle away from moisture. If possible, handle material in an efficient fume hood. Prolonged exposure to the atmosphere may lead to degradation of 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: | If possible, handle the material in an efficient fume hood. |
| Respirator: | In the absence of adequate ventilation a respirator should be worn. The use of a respiratory requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134. |
| Additional Protection: | No additional protection required. |
