Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, dry powder, carbon dioxide, foam, depending on surrounding materials
Unsuitable Extinguishing Media: Do not use water jet directly on substance
Hazardous Combustion Products: May include copper oxides, carbon dioxide, small amounts of carbon monoxide
Fire Hazards: Non-flammable under standard conditions, decomposes with heat to release toxic fumes
Special Protective Equipment for Firefighters: Wear full protective gear, including self-contained breathing apparatus
Firefighting Procedures: Cool containers with water from a safe distance, avoid breathing fumes, remain upwind

Accidental Release Measures

Personal Precautions: Wear protective clothing, gloves, safety goggles, and appropriate face protection, restrict access to area
Environmental Precautions: Prevent product from entering drains, waterways, and soil, keep away from vegetation
Methods for Clean-up: Shovel or sweep up dry material, place in a properly labeled container, avoid raising dust, ventilate area
Spill Response: Wash contaminated area with water and detergent, collect washings for disposal
Disposal of Cleanup Materials: Dispose according to local regulations for hazardous waste

Handling and Storage

Handling: Use only with adequate ventilation, minimize dust generation, avoid breathing dust or contact with skin and eyes, do not eat or drink in working area, wash hands after handling
Storage: Store in original tightly closed containers, keep in cool, dry, well-ventilated place away from acids and reducing agents, protect from moisture and direct sunlight
Storage Temperature: 2–30°C is best for long-term stability
Incompatible Materials: Avoid contact with acids, ammonium salts, strong oxidizers, strong reducing agents
Segregation Requirements: Store separately from chemicals that react with copper compounds

Exposure Controls and Personal Protection

Occupational Exposure Limits: ACGIH TLV for copper dust and mist: 1 mg/m³ (as Cu); OSHA PEL for copper dusts and mists: 1 mg/m³ (as Cu)
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits
Personal Protective Equipment: Wear chemical-resistant gloves, safety goggles or face shield, long-sleeved clothing, dust mask or respirator if dust exceeds limits
Environmental Controls: Control runoff and prevent release into sewers or natural water bodies
Hygiene Measures: Wash hands and face after handling, promptly remove contaminated clothing and wash before reuse
