Impurities: Typical preparations contain less than 1% unknown or unclassified trace contaminants

First Aid Measures

General Advice: Move away from exposure, consult medical help promptly
Inhalation: Remove person to fresh air, keep at rest, seek medical advice if symptoms like dizziness, coughing, or breathing difficulty develop
Skin Contact: Remove contaminated clothing, rinse with running water for several minutes, seek attention for persistent irritation
Eye Contact: Rinse eyes carefully for at least 15 minutes, lifting eyelids occasionally, seek immediate medical attention for redness or pain
Ingestion: Rinse mouth if person is conscious, do not induce vomiting, get medical advice promptly

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, water spray only in large fires and with caution
Unsuitable Extinguishing Media: Direct water jets may spread the chemical
Hazardous Combustion Products: Emits toxic fumes of copper oxides and acetic acid under fire conditions
Firefighter Protection: Wear self-contained breathing apparatus and full protective gear, avoid inhaling fumes
Special Procedures: Remove containers from fire zone if safe, cool exposed containers with water, prevent runoff into drains and waterways

Accidental Release Measures

Personal Precautions: Evacuate area if necessary, ensure adequate ventilation, use personal protective equipment to prevent skin and eye contact, avoid breathing dust
Environmental Precautions: Prevent entry into soil, drains, and water bodies, inform authorities if large amounts enter environment
Cleanup Methods: Pick up mechanically or use damp cloth, place in suitable closed container, wash spill site thoroughly with detergent and water, avoid raising dust during cleanup

Handling and Storage

Safe Handling: Handle in chemical fume hood or well-ventilated area, avoid contact with skin, eyes, and clothing, do not eat, drink, or smoke where chemical is used, wash hands after use
Storage Conditions: Store in cool, dry, well-ventilated location, keep container tightly sealed, protect from sunlight, moisture, incompatible materials such as strong oxidizers and acids, separate from food and feedstuffs

Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific limit data found for copper(I) acetate, limit for copper dust and mists recommended at 1 mg/m3 (ACGIH TLV)
Engineering Controls: Chemical fume hoods, local exhaust ventilation, maintain negative pressure in the lab
Personal Protective Equipment: Chemical safety goggles, rubber or neoprene gloves, laboratory coat, dust mask or respirator complying with approved standards, avoid contact lenses
Hygiene Measures: Remove contaminated clothing, wash thoroughly before breaks, after work, and if contamination occurs, do not bring personal items into chemical use areas

Physical and Chemical Properties

Stability and Reactivity

Chemical Stability: Stable under recommended handling and storage, sensitive to air and moisture
Reactivity: Reacts with acids, bases, strong oxidizers, generates flammable hydrogen gases with contact to metals
Hazardous Reactions: Exposure to moist air and light may cause slow oxidation
Hazardous Decomposition Products: Copper oxides, acetates, acetic acid fumes if heated strongly
Conditions to Avoid: Moisture, intense heat, and incompatible compounds increase risk of hazardous decomposition

Toxicological Information

Acute Toxicity: Ingestion leads to nausea, vomiting, abdominal pain, copper poisoning if high amounts are taken, LD50 in rats reported near 60 mg/kg
Skin Corrosion/Irritation: May cause redness, irritation, or rashes upon repeat contact
Serious Eye Damage/Irritation: Irritation and redness in case of direct contact, possible conjunctivitis
Respiratory Effects: Inhalation triggers coughing, shortness of breath, irritation to upper respiratory tract
Chronic Effects: Repetitive exposure can affect liver and kidneys, cause anemia, or disturb central nervous system
Carcinogenicity: Not classified as carcinogen; long term studies lacking
Other Data: People with preexisting conditions may be more sensitive, especially to copper exposure in blood and metabolism

Ecological Information

Aquatic Toxicity: Highly toxic to aquatic organisms including fish, may cause long-lasting harm in the water column
Persistence and Degradability: Does not readily break down in nature, copper accumulates in sediments
Bioaccumulative Potential: Copper can bioaccumulate in aquatic life, cause ecosystem damage
Mobility in Soil: Moderate mobility, binds to soil and sediments but may leach under acidic conditions
Other Adverse Effects: Should not enter surface waters, storm drains, or sewers due to risk to plants and animals

Disposal Considerations

Waste Disposal Methods: Treat as hazardous waste under local, regional, national regulations, collect solid residues in proper containers for approved disposal
Contaminated Packaging: Rinse containers, dispose in compliance with regulatory guidelines
