Inhalation: Move person to fresh air; keep at rest; seek medical advice if symptoms persist such as coughing or shortness of breath.
Skin Contact: Immediately wash affected area with soap and plenty of water for at least 15 minutes; remove contaminated clothing and do not reuse until washed; get medical attention for persistent irritation.
Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if present and easy to do; keep eye open while rinsing; immediate medical attention if redness or pain continues.
Ingestion: Do not induce vomiting; rinse mouth with water; if conscious, give water to drink; seek immediate medical advice or contact poison control.
Suitable Extinguishing Media: Water spray, foam, dry powder, carbon dioxide
Unsuitable Extinguishing Media: Do not use high-pressure water jets that may spread material
Fire Hazards: During combustion, releases toxic gases including nitrogen oxides, copper oxides, carbon oxides
Protection for Firefighters: Wear full protective gear, self-contained breathing apparatus
Advice: Move containers away from fire if safe to do so, avoid inhaling smoke, keep run-off out of drains and water bodies
Personal Precautions: Use personal protection such as gloves, goggles, laboratory coat; avoid breathing dust and direct contact
Environmental Precautions: Prevent further leakage or spillage; avoid discharge into drains, waterways or soil
Cleanup Methods: Sweep up and shovel spilled material; place in suitable closed containers for disposal; ventilate area; wash spill site after removal
Emergency Procedures: Notify responsible authorities if large amounts released or spill has entered natural environment
Handling: Work in well-ventilated area or chemical fume hood; avoid generation of dust; minimize contact with skin, eyes, and clothing; do not eat, drink, or smoke while using product; wash hands after handling
Storage Conditions: Store in original tightly closed container in cool, dry, well-ventilated location away from incompatible substances like strong acids and oxidizers; avoid exposure to moisture; ensure secondary containment if stored near drains
Occupational Exposure Limits: No established limits for the compound; copper: OSHA PEL TWA 1 mg/m³ (dust and mist)
Engineering Controls: Local exhaust ventilation or chemical fume hood strongly recommended
Personal Protection: Safety goggles, chemical-resistant gloves (nitrile or neoprene), laboratory coat
Respiratory Protection: Use approved dust mask or respirator if dust or aerosols generated, especially above exposure limits
Hygiene: Remove contaminated clothing and wash before reuse; avoid direct contact with skin and mucous membranes
Appearance: Blue to green crystalline powder
Odor: Faint or no odor
Solubility: Soluble in water, forms colored solution
Melting Point: Not well defined, decomposition at >200°C
Boiling Point: Not applicable (decomposes)

Auto-ignition Temperature: Not applicable
Explosive Limits: Data not available
Chemical Stability: Stable under normal laboratory conditions, decomposes under strong heating
Reactivity: Reacts with strong acids, oxidizing agents, reducing agents
Conditions to Avoid: Moisture, excessive heat, direct sunlight, incompatible materials
Decomposition Products: May release hazardous gases such as copper oxides, nitrogen oxides, carbon monoxide and carbon dioxide on strong heating or burning
Polymerization: Does not polymerize
Likely Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Effects: Irritation to skin, eyes, respiratory tract; may cause nausea, vomiting, diarrhea on swallowing
Chronic Effects: Prolonged or repeated exposure may cause skin and respiratory sensitization; copper accumulates in the body and may cause systemic toxicity; associated with liver and kidney effects
Toxicity Data: Imidazole oral LD50 (rat): 970 mg/kg; Copper(II) compounds oral LD50 (rat): 300 mg/kg; mixture can be harmful if swallowed
Symptoms: Redness, itching, respiratory discomfort, gastrointestinal upset
Carcinogenicity: Not classified as carcinogenic by IARC or NTP
Mutagenicity: Data not available for this complex compound
Reproductive Toxicity: No evidence to suggest concern for human health at laboratory exposure levels
Aquatic Toxicity: Very toxic to aquatic life due to copper ion; fish and invertebrates are particularly sensitive; imidazole can also cause harmful effects to water organisms
Persistence/Degradability: Imidazole ring subject to microbial breakdown in soil and water, persistent if released in large quantities
Bioaccumulation: Copper can accumulate in bottom sediments and biota
Mobility in Soil: Copper ions can bind strongly to soil particles, imidazole has high mobility in aqueous phase
Other Harmful Effects: Avoid making solutions or releasing powders near drains, stormwater, or natural waterways due to risk of toxicity to aquatic systems
Waste Treatment Methods: Collect all excess material, contaminated containers, and cleaning residues in labeled hazardous waste containers; do not flush into drains or sewers
Disposal Procedures: Dispose of this material and its container at a licensed chemical waste disposal facility; consult local regulations for proper disposal
Landfill Ban: Not suitable for landfill disposal in most regions
Incineration: High-temperature incineration with flue gas scrubbing recommended for complete destruction
Container Disposal: Containers should be triple-rinsed and managed as hazardous waste unless fully decontaminated
