Inhalation: Move person to fresh air. Get medical attention if symptoms develop.
Skin Contact: Remove contaminated clothing. Wash skin with plenty of soap and water. Seek medical help if irritation persists.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Get medical attention if irritation occurs.
Ingestion: Rinse mouth. Do not induce vomiting. Seek immediate medical advice.
Symptoms and Effects: Ingestion can cause nausea, vomiting, abdominal pain. Eye exposure may result in redness, tearing, or pain.
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide.
Specific Hazards: Product itself does not burn, but heated material releases toxic copper fumes and hydrogen chloride gas.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear.
Advice for Firefighters: Prevent run-off from entering drains or water sources. Cool containers with water spray.
Personal Precautions: Wear protective clothing, gloves, goggles, and suitable respiratory protection. Keep unprotected individuals away.
Environmental Precautions: Do not allow product to reach sewage systems or waterways. Contain spill to prevent environmental contamination.
Methods for Clean-Up: Sweep up and place into suitable labeled containers for disposal. Do not dry sweep. Wash spill site after material pickup. Ventilate area well.
Handling: Avoid breathing dust. Avoid direct contact with skin and eyes. Handle in well-ventilated areas. Do not mix with acids or reducing agents.
Storage: Store in tightly closed containers in a cool, dry, well-ventilated place. Keep away from incompatible materials, foodstuffs, and animal feed. Store at room temperature. Protect from moisture and direct sunlight.
Specific End Uses: Industrial, agricultural, and laboratory use only.
Occupational Exposure Limits: Copper compounds (as Cu): ACGIH TLV 1 mg/m3 (dust and mists), OSHA PEL 1 mg/m3
Engineering Controls: Provide local exhaust ventilation. Use closed system transfer where possible.
Personal Protective Equipment: Protective gloves (nitrile, PVC), chemical-resistant goggles, long-sleeved clothing, disposable coveralls if necessary. Dust mask or respirator approved for particulates.
Hygiene Measures: Wash hands before breaks and at the end of work. Remove contaminated clothing and wash before reuse.

Acute Toxicity: Oral LD50 (rat): 300–600 mg/kg
Skin Corrosion/Irritation: May cause skin irritation in prolonged or repeated exposure
Serious Eye Damage/Irritation: Causes eye irritation, redness, and discomfort
Respiratory Sensitization: Inhalation of dust may cause coughing, respiratory tract irritation
Chronic Effects: Prolonged exposure may affect liver and kidneys; chronic copper poisoning possible with high exposures
Carcinogenicity, Mutagenicity, Reproductive Toxicity: Not listed as carcinogen by IARC, NTP, OSHA; no known mutagenic or reproductive hazards from standard exposures
Ecotoxicity: Highly toxic to fish and aquatic organisms; LC50 (fish, 96h): <1 mg/L
Persistence and Degradability: Does not degrade rapidly in the environment
Bioaccumulation Potential: Copper accumulates in aquatic life, especially mollusks and crustaceans
Mobility in Soil: Strong adsorption to soil particles; low mobility unless in acidic or contaminated soils
Other Adverse Effects: May disrupt aquatic ecosystems and soil microbiology if released in large quantities
Waste Disposal Methods: Dispose of contents and container according to local, regional, and national regulations. Chemical residues should not be discharged to drain systems. Contaminated packaging should be emptied completely, rinsed, and then disposed or recycled according to local waste rules.
Special Precautions: Do not contaminate ponds, waterways, or ditches with chemical or used container
