Protective Equipment for Firefighters: Full protective clothing, self-contained breathing apparatus recommended
Precautions: Avoid inhalation of fumes or smoke. Dike runoff water to prevent environmental contamination.
Personal Precautions: Wear gloves, goggles, lab coat or apron. Avoid generating dust.
Spill Response: Sweep up carefully. Place spill residue into a properly labeled container for disposal. Wash area with copious water.
Environmental Precautions: Prevent entry into drains, sewers, waterways. Notify relevant authorities if water contamination occurs.
Cleanup Methods: Scoop up material, clean area fully to minimize dust formation.
Handling: Keep container tightly closed. Avoid creating or breathing dust. Use only with adequate ventilation. Keep out of reach of children and unauthorized users.
Hygiene Recommendations: Wash hands after handling. Do not eat, drink, or smoke in work area.
Storage: Store in a dry, cool, well-ventilated place away from incompatible materials like strong acids or oxidizers. Prevent moisture ingress. Store in original, clearly labeled containers.
Engineering Controls: Use with local exhaust or in a chemical fume hood. Ensure eye-wash stations and emergency showers are nearby.
Personal Protective Equipment: Chemical-resistant gloves (nitrile recommended), laboratory coat, safety goggles or face shield, dust mask or respirator as needed.
Occupational Exposure Limits: OSHA PEL for copper dust and mists: 1 mg/m³ (TWA). ACGIH TLV: 1 mg/m³ (TWA, inhalable fraction).
Environmental Protection: Employ appropriate measures to avoid contamination during handling—including spill containment.

Polymerization: Not expected
Routes of Exposure: Inhalation, ingestion, skin, eyes
Symptoms of Exposure: Coughing, irritation, nausea, vomiting, diarrhea, redness or pain to skin and eyes
Acute Toxicity: LD50 (oral, rat) estimated > 300 mg/kg (for copper salts)
Chronic Effects: Prolonged exposure may cause liver and kidney effects, or anemia due to copper accumulation
Carcinogenicity: Not listed as carcinogen by IARC, NTP, OSHA
Other Data: Individuals with Wilson’s disease or other copper storage disorders may face health risks at lower exposures.
Aquatic Toxicity: Toxic to aquatic organisms, may cause long lasting effects in aquatic environments
Mobility in Soil: Copper binds strongly to soils; runoff may impact local water quality
Bioaccumulation Potential: Copper may bioaccumulate in aquatic life and plants
Degradability: Inorganic compound, not biodegradable but may be chemically transformed or partitioned into soil/sediment
Other Adverse Effects: Avoid release to the environment—copper accumulation can harm plants and fish.
