|---|---|
| Emergency Overview: | May cause sensitization by inhalation and skin contact. May be irritating to skin, eyes and respiratory tract. Limited evidence of a carcinogenic effect. Possible risk of irreversible effects |
| Primary Routes of Exposure: | Ingestion, inhalation, skin contact |
| Eye Contact: | May cause mild to moderate irritation of the eyes. |
| Skin Contact: | May cause irritation of the skin. May cause sensitization in contact with skin. |
| Inhalation: | May be irritating to the nose, mucous membranes and respiratory tract. May cause sensitization by inhalation. |
| Ingestion: | No information on the physiological effects of ingestion. May be harmful if swallowed. |
| Acute Health Effects: | May cause sensitization by inhalation and skin contact. May be irritating to skin, eyes and respiratory tract |

| 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 soap and 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. |

|---|---|
| Flash Point: | no data |
| Autoignition Temperature: | no data |
| Explosion Limits: | no data |
| Extinguishing Medium: | Class D metal fire agent, dry salt or sand |
| 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, burning metal may produce mildly irritating fumes of cobalt oxide |
| Unusual Fire or Explosion Hazards: | Flammable solid. Dust may form explosive mixtures with air. |
| SECTION 6: Accidental Release Measures | |
|---|---|
| Spill and Leak Procedures: | Small spills can be mixed with vermiculite, ground limestone or soda ash and swept up. |
| SECTION 7: Handling and Storage | |
|---|---|
| Handling and Storage: | Store in a tightly sealed container in a cool, dry place. Use good housekeeping practice to avoid accumulation of spilled dust and so avoid the resulting fire hazard. |
| 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: | If ventilation is not available, a respirator should be worn. The use of respirators requires a Respiratory Protection Program to be in compliance with 29 CFR 1910.134. |
| Additional Protection: | No additional protection required. |
