Hazards From Combustion: Hydrogen chloride gas, copper fumes
Protective Equipment: Full fire gear, self-contained breathing apparatus
Fire-Fighting Instructions: Evacuate area, prevent runoff to sewers, cool containers exposed to fire

Accidental Release Measures

Personal Precautions: Use personal protective equipment; avoid contact with skin and eyes.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains, waterways, or soil.
Cleanup Methods: Sweep up gently using non-sparking tools. Collect in suitable container for disposal. Ventilate affected area.
Spill Response: Store collected material in properly labeled chemical waste container.

Handling and Storage

Safe Handling: Use only in well-ventilated areas. Avoid dust formation and contact with eyes, skin, or clothing.
Storage Conditions: Store in tightly closed containers in cool, dry, well-ventilated location, away from sources of humidity and incompatible materials such as strong acids and bases.
Incompatibles: Strong oxidizing agents, metals such as sodium, potassium, magnesium

Exposure Controls and Personal Protection

Exposure Limits: Occupational exposure levels for copper dust/fume: OSHA PEL – 1 mg/m³ (fume)
Engineering Controls: Use local exhaust ventilation to minimize airborne dusts and vapors.
Personal Protective Equipment: Chemical-resistant gloves, laboratory coat, splash-resistant goggles, appropriate respirator in dust-generating areas.
Hygiene Measures: Wash thoroughly after handling. Change contaminated clothing.
