| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Irritating to skin, eyes and respiratory tract. Inhalation hazard if dehydrated to a fine dust or fume. |
| Primary Routes of Exposure: | Ingestion, inhalation (of dust or fume) |
| Eye Contact: | The dust (after dehydration or water slurry) causes mild to moderate irritation of the eyes. |
| Skin Contact: | The powder causes mild to moderate irritation of the skin. |
| Inhalation: | Hazard associated with inhalation of dried fine dust or fume. Irritating to nasal cavity and respiratory tract. |
| Ingestion: | Ingestion can cause irritation of the mouth, throat, and esophagus |
| Acute Health Effects: | Irritating to skin, eyes and respiratory tract. Ingestion can lead to gastrointestinal effects, vomiting and nausea. |
| Chronic Health Effects: | Long term skin or inhalation exposure to powder may lead to an allergic reaction in some susceptible individuals. |
| 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. |
| SECTION 5: Fire Fighting Measures | |
|---|---|
| Flash Point: | not applicable |
| Autoignition Temperature: | 68°F as dust |
| Explosion Limits: | unknown |
| Extinguishing Medium: | Class D metal fire agent, dry salt or sand. |
| Special Fire Fighting Procedures: | Burning metal produces zirconium dioxide fumes. Fire fighters should be equipped with a self-contained breathing apparatus. |
| Hazardous Combustion and Decomposion Products: | Zirconium oxide as an oxidation product. |
| Unusual Fire or Explosion Hazards: | Material may spontaneously ignite on exposure to air, especially in the form of a dry fine dust. |
| SECTION 6: Accidental Release Measures | |
|---|---|
| Spill and Leak Procedures: | In the case of a spill, the fine powder should be covered with sodium carbonate or dolomite in order to reduce the formation of dust. Sweep up the mixture. |
| SECTION 7: Handling and Storage | |
|---|---|
| Handling and Storage: | Store and handle the material under an inert atmosphere of nitrogen or argon. |
| 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. |
| Ventilation: | If in the form of a dry fine dust, handle the material in an efficient fume hood. |
| Respirator: | If handling material in the form of a dry 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. |
