First Aid Measures

Inhalation: Remove to fresh air. Seek medical attention if symptoms such as coughing or respiratory distress occur.
Skin Contact: Wash thoroughly with soap and water. Remove contaminated clothing.
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, keeping eyelids open. Remove contact lenses if present.
Ingestion: Rinse mouth. Do not induce vomiting. Call poison control or seek medical advice if large quantities are ingested or symptoms develop.

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Unsuitable Media: Avoid high-pressure streams which could spread powder
Hazardous Combustion Products: Carbon oxides, copper oxides, possible toxic fumes
Personal Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective clothing
Specific Hazards: Product does not readily burn but decomposes at high temperature to form copper oxides and carbon monoxide. Avoid inhalation of combustion products.

Accidental Release Measures

Personal Precautions: Use respiratory protection for dusty spills. Avoid contact with eyes and skin.
Environmental Precautions: Prevent entry into drains, soil, or waterways.
Clean-up Methods: Sweep up material and place in sturdy, well-labeled containers for disposal. Avoid creating airborne dust. Wash contaminated surfaces with water. Wear gloves and goggles.
Reporting: Notify authorities if large release enters environment or water supply.

Handling and Storage

Handling: Avoid generating dust during transfer. Wear appropriate protective gear. Practice good hygiene after handling.
Storage Conditions: Store in a cool, dry, ventilated area. Keep away from incompatible materials such as strong acids, alkalis, or reducing agents. Keep container tightly closed when not in use.
Storage Incompatibilities: Do not store with strong oxidizers or flammable chemicals. Avoid storage in metal containers susceptible to corrosion.

Exposure Controls and Personal Protection

Ventilation: Use local exhaust or general ventilation to minimize exposure.
Respiratory Protection: Dust mask or NIOSH-approved respirator for dust-producing tasks.
Eye Protection: Safety glasses or chemical splash goggles.
Skin Protection: Chemical-resistant gloves, lab coat or protective clothing.
Exposure Limits: Not established for copper gluconate; copper compounds (dust/mist) ACGIH TLV: 1 mg/m³ (as Cu); OSHA PEL: 1 mg/m³ (as Cu)

Toxicological Information

Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Acute Toxicity: Oral (rat) LD50: estimated > 1300 mg/kg
Chronic Effects: Prolonged ingestion of copper salts may cause anemia, liver, or kidney damage; possible gastrointestinal disturbances
Irritation: Causes eye irritation; mild skin irritation in some cases
Sensitization: Not expected to cause skin sensitization based on available data
Carcinogenicity: No component listed as carcinogen by IARC, NTP, or OSHA
Other Information: Occupational exposure limits relate to copper dusts and mists; excessive amounts have potential for systemic toxicity

Ecological Information

Ecotoxicity: Toxic in high concentrations to aquatic organisms due to copper content
Mobility: Soluble in water, can migrate in water systems
Persistence and Degradability: Compound not expected to degrade rapidly in environment, metal ions persist
Bioaccumulation: Copper may bioaccumulate in aquatic organisms
Other Adverse Effects: Spillage to local environment should be avoided, particularly watercourses

Disposal Considerations

Waste Disposal Methods: Dispose of material in accordance with local, regional, and national regulations. Do not allow entry to drains or surface water.
