First Aid Measures

Inhalation: Move affected person to fresh air, support breathing as needed, seek immediate medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, rinse skin with plenty of water for at least 15 minutes, use mild soap, obtain medical advice if irritation continues
Eye Contact: Rinse cautiously with water for several minutes, lift eyelids to ensure complete flushing, remove contact lenses if easy, seek medical help if irritation stays
Ingestion: Rinse mouth, call poison center or doctor right away, avoid inducing vomiting unless directed by a medical professional, observe for abdominal pain or vomiting

Fire-Fighting Measures

Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide depending on the nature of the surrounding fire
Hazards from Combustion: Copper oxides and acetic acid fumes can form, both pose respiratory risk
Protective Equipment for Firefighters: Wear full protective gear including self-contained breathing apparatus, avoid inhaling combustion products, and approach from upwind

Accidental Release Measures

Personal Protection: Slip on gloves, safety goggles, and a lab coat; avoid breathing dust and limit spread with local ventilation
Environmental Precautions: Contain spill to keep copper compounds from reaching sewers or waterways, use inert materials like sand to dike and absorb
Clean-Up Methods: Collect the spilled substance carefully, sweep into a sealable container, dispose of as hazardous waste, ventilate area thoroughly after cleanup

Handling and Storage

Safe Handling: Avoid skin and eye contact, minimize dust formation, use only in well-ventilated settings, do not eat or drink while handling
Storage Conditions: Keep container tightly closed in a cool, dry, well-ventilated spot, protect from moisture, store away from strong acids and reducing agents
Compatibility Precautions: Do not store with oxidizing materials, ensure containers remain clearly labeled and tightly sealed between uses

Exposure Controls and Personal Protection

Occupational Exposure Limits: ACGIH TLV (Copper, dusts and mists): 1 mg/m³ TWA
Engineering Controls: Use process enclosures, exhaust ventilation, or other engineering controls to control airborne dust levels
Personal Protective Equipment: Wear chemical-resistant gloves, safety goggles, respirator mask in powder-handling operations, lab coat or apron, and closed-toe footwear
Hygiene Measures: Wash thoroughly after use, do not eat, drink, or smoke in areas where the chemical is used

Toxicological Information

Acute Toxicity: Oral LD50 (rat): 710 mg/kg, can cause vomiting, diarrhea, convulsions
Skin and Eye Effects: Skin and eye irritant, may cause rash and inflammation
Chronic Effects: Repeated exposure can result in liver and kidney damage, potential anemia from copper accumulation
Carcinogenicity: Not listed by IARC/NTP/OSHA as carcinogen, but copper compounds warrant careful handling
Sensitization: Not proven to sensitize, but skin irritation may increase with repeated exposure

Ecological Information

Aquatic Toxicity: Very toxic to aquatic organisms, LC50 (fish): 0.3-4.5 mg/L, may cause long-term harmful effects in aquatic environments
Persistence and Degradability: Not rapidly biodegradable, persists in soils and sediments
Bioaccumulation: Copper ions bioaccumulate in organisms like shellfish and algae, can transfer through food chains
Other Adverse Effects: Disrupts microbial activity in soil and water, impacts plant growth in contaminated regions

Disposal Considerations

Disposal Methods: Transfer waste to a licensed chemical waste contractor, avoid dumping into drains or waterways
Container Disposal: Rinse containers with water, neutralize washings, puncture and dispose of per local regulations
Precautions: Clearly label waste containers, segregate from general trash, follow state and federal hazardous waste guidelines
