| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Irritating to skin and eyes. Due to auto ignition of drying slurry, an inhalation hazard exists due to burning copper fume and contact with skin can produce thermal burns. |
| Primary Routes of Exposure: | Ingestion, inhalation. Contact with skin and eyes. |
| Eye Contact: | The dust (after dehydration of water slurry) causes mild to severe irritation or burns to the eyes. |
| Skin Contact: | The powder causes irritation and may cause burns upon auto ignition when dry. |
| Inhalation: | Hazard associated with inhalation of dried fine dust or fume. May be irritating to nasal cavity and respiratory tract. |
| Ingestion: | Ingestion can cause irritation of the mouth, throat, and esophagus |
| Acute Health Effects: | Powder is irritating to skin and eyes and may cause burns. May be irritating to the respiratory tract. Ingestion can lead to gastrointestinal effects, vomiting and nausea. |
| Chronic Health Effects: | No information available on long-term chronic effects. |
| 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: | unknown |
| Explosion Limits: | unknown |
| Extinguishing Medium: | Class D metal fire agent, dry salt or sand. |
| 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. |
| Hazardous Combustion and Decomposion Products: | Copper oxide as an oxidation product. |
| Unusual Fire or Explosion Hazards: | Material will spontaneously ignite on exposure to air if allowed to dry. |
| 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 and deactivated with aqueous hypochlorite common household bleach before cleanup to avoid fires. |
| 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. |
