First Aid Measures
Inhalation: Move to fresh air, support breathing as needed, seek medical attention if symptoms develop
Skin Contact: Remove contaminated clothing, rinse skin with plenty of water for at least 15 minutes, consult physician if irritation persists
Eye Contact: Rinse eyes with water for several minutes, remove contact lenses, seek medical attention if discomfort continues
Ingestion: Rinse mouth, drink water, do not induce vomiting, seek medical advice without delay
Self-Protection: Use gloves, respirators, and goggles for direct aid when risk of exposure is likely
Fire-Fighting Measures
Suitable Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or foam
Specific Hazards: May produce toxic copper and phosphorus oxides when heated
Protective Equipment: Wear full protective clothing, use self-contained breathing apparatus
Fire Fighting Instructions: Approach from upwind, prevent spillage from entering waterways, cool containers with water fog
Hazardous Combustion Products: Phosphorus oxides, copper oxides, irritating fumes
Accidental Release Measures
Personal Precautions: Wear proper protective equipment including respirators for dust control
Environmental Precautions: Prevent contamination of waterways, soil, and drains
Methods for Containment: Prevent dust formation, collect with shovel or vacuum device, avoid generating airborne particles
Cleanup Procedures: Place recovered material in secure containers for disposal; ventilate area thoroughly; wash spill site after material pickup
Notification: Report significant spills to environmental authorities as required by regulations
Handling and Storage
Safe Handling: Keep container tightly closed; handle in a well-ventilated area; use personal protective equipment; avoid creating or inhaling dust
Storage Requirements: Store in a cool, dry location away from incompatible substances such as acids or oxidizing agents
Storage Conditions: Store in corrosion-resistant containers; avoid exposure to moisture; keep away from food and drink
Packaging: Ensure proper labelling on containers; store below 25°C
Incompatibilities: Strong acids, oxidizers, ammonia compounds
Exposure Controls and Personal Protection
Exposure Limits: ACGIH TLV (Copper, metal dust and mist) 1 mg/m3 (TWA); OSHA PEL 1 mg/m3 (TWA)
Engineering Controls: Use local exhaust ventilation to minimize airborne levels
Personal Protective Equipment: Safety goggles for eyes, chemical-resistant gloves, lab coat, respiratory protection where ventilation insufficient

Toxicological Information
Acute Toxicity: Can cause gastrointestinal irritation, nausea, vomiting if ingested; inhalation may irritate respiratory tract
Chronic Effects: Prolonged skin contact may cause dermatitis; chronic copper exposure can lead to liver, kidney injury
Carcinogenicity: No evidence of carcinogenicity for copper pyrophosphate
Sensitization: May cause allergic reactions in sensitive persons through prolonged contact
Mutagenicity: No data available
Symptoms of Overexposure: Nausea, abdominal pain, headache, drowsiness, confusion at high exposures
Routes of Entry: Inhalation, skin, eyes, ingestion
Ecological Information
Aquatic Toxicity: Very toxic in aquatic environments, especially to fish and aquatic invertebrates due to copper ions
Persistence and Degradability: Partially persistent; copper ions do not break down, can accumulate in sediments
Bioaccumulation: Copper compounds may accumulate in biological tissue
Mobility: Slows movement through soils; dissolves in acidic water, increasing mobility
Additional Hazards: Avoid release to waterways, risk of ecosystem damage if large amounts enter soil or water
Disposal Considerations
Waste Treatment Methods: Collect and seal material in approved containers for disposal according to local regulations
RCRA Classification: May be classified as hazardous waste under RCRA depending on local regulations
