Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: Avoid high-pressure water streams
Specific Hazards: Copper oxides can form in fire, possible generation of irritating fumes
Protective Equipment for Firefighters: Wear full protective gear including self-contained breathing apparatus, use water spray to cool containers near fire

Accidental Release Measures

Personal Precautions: Evacuate area, keep unnecessary personnel away, use respiratory protection in dusty environments
Environmental Precautions: Prevent release into sewers, drains, or waterways to avoid harm to aquatic life
Methods for Cleanup: Sweep or shovel material into appropriate container for disposal, avoid raising dust, ventilate affected area well

Handling and Storage

Handling: Use with adequate ventilation, avoid breathing dust or getting material on skin, remove contaminated clothing, keep away from food and drink
Storage: Store in a sealed container, keep in a dry place at ambient temperature, separate from acids and incompatible chemicals, label container clearly, avoid moisture intrusion

Exposure Controls and Personal Protection

Exposure Limits: ACGIH TLV for copper dust and mists: 1 mg/m³, OSHA PEL: 1 mg/m³ (as copper)
Engineering Controls: Use local exhaust ventilation to keep airborne concentrations below recommended exposure limits, enclose processes as needed
Personal Protective Equipment (PPE): Safety goggles for splash protection, gloves resistant to chemicals, laboratory coat or apron, dust mask or respirator if airborne dust is generated
Hygiene Measures: Wash hands thoroughly after handling, keep contaminated clothing out of common areas, avoid eating or smoking near material
