GHS Pictograms: Exclamation mark
Precautionary Statements: Use with ventilation, avoid breathing dust, wear protective gloves and eye protection, wash hands after handling, keep out of reach of children
Copper Oxide (CuO): 99% or higher by weight
Other Constituents: May include trace levels of impurities not contributing to hazard classification
Occupational Exposure Limits: Refer to OSHA PEL and ACGIH TLV guidelines for copper dust and fume
Inhalation: Move to fresh air, monitor breathing, seek medical care if symptoms continue
Skin Contact: Wash with plenty of soap and water, remove contaminated clothing, medical attention if irritation remains
Eye Contact: Rinse carefully with water for at least 15 minutes, remove contact lenses, contact a physician in case of persistent pain
Ingestion: Rinse mouth, drink water to dilute, do not induce vomiting, contact poison control right away
Important Notes: Provide this sheet to medical personnel, no specific antidote for copper oxide poisoning
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, or foam for surrounding fire, copper oxide itself does not burn
Unsuitable Media: Avoid water spray on molten copper oxide
Special Hazards: May release toxic copper fumes if involved in a fire, dust may create hazardous conditions
Protective Equipment: Firefighters to use full protective gear and self-contained breathing apparatus
Precautions: Cool containers exposed to fire with water spray, avoid breathing fumes
Personal Precautions: Wear appropriate PPE including gloves, goggles, dust mask or respirator
Environmental Precautions: Prevent product from entering drains, soil, and waterways, alert authorities if large spill occurs
Cleanup Methods: Use damp methods or HEPA-filtered vacuum, avoid creation of dust clouds, collect residue in clearly labeled containers, dispose according to regulations
Decontamination: Clean area thoroughly with water after material removed
Handling: Use only in well-ventilated areas, avoid generating dust, wash hands before eating or drinking, keep work area clean to prevent accidental release
Storage: Store in tightly closed containers in dry, cool, well-ventilated space, keep away from acids and incompatible materials, segregate from food and animal feed, label containers with hazard information
Exposure Limits: OSHA PEL for copper dust and mist 1 mg/m³ (TWA), ACGIH TLV 1 mg/m³ (TWA)
Engineering Controls: Local exhaust ventilation, process enclosures, dust collection systems
Personal Protective Equipment: Approved dust respirators or masks, chemical-resistant gloves, safety goggles, protective clothing
Hygiene Measures: Wash hands before breaks and after handling, avoid contact with skin, eyes, and clothing

Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Effects: Harmful by ingestion and inhalation, causes irritation to eyes, skin, and respiratory tract, may cause nausea or vomiting
Chronic Effects: Prolonged exposure can affect liver and kidneys, cause anemia, copper poisoning symptoms (vomiting, abdominal pain, jaundice)
Carcinogenicity: Not classified as a carcinogen by OSHA, IARC, or NTP at usual exposure levels
Other Effects: Allergic skin reactions uncommon but possible for susceptible persons
Aquatic Toxicity: Copper oxide toxic to aquatic life, acute and long-term effects on fish and invertebrates
Persistence and Degradability: Not readily biodegradable, persistent in soil and water
Bioaccumulation: Copper can bioaccumulate in aquatic organisms
Mobility in Soil: Low solubility means limited mobility, but can migrate with surface water
Other Information: Limit release to environment whenever possible, avoid uncontrolled disposal in sewers or waterways
Waste Disposal Methods: Dispose of in accordance with local, state, national regulations, consult approved waste disposal operators
Container Handling: Empty containers retain product residues, handle contaminated packaging in the same way as product
Special Considerations: Don’t reuse packaging, avoid disposal in regular trash if possible, secure as hazardous waste if regulatory threshold met
UN Number: Not regulated under most international transportation regulations in standard amounts
DOT/IATA/IMDG Labels: Typically not dangerous goods, check with carrier in case of bulk shipment
Special Precautions: Prevent package damage during transit, keep containers sealed, indicate hazard class if applicable
Transport in Bulk: Follow warehouse and carrier safety rules, use approved containers
OSHA: Listed as hazardous chemical under the HCS
SARA Title III: Subject to reporting for releases above reportable quantities
TSCA: Listed in the United States TSCA inventory
WHMIS: Classified under Canadian regulations
