Inhalation: Move affected person to fresh air; seek medical attention if symptoms persist such as coughing, shortness of breath, throat irritation.
Skin Contact: Remove contaminated clothing; wash skin thoroughly with soap and water; consult a doctor if irritation or rash appears.
Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if present and easy to do; continue rinsing; obtain medical attention if irritation persists.
Ingestion: Rinse mouth, do not induce vomiting; get medical help immediately if feeling unwell or if large amounts swallowed.
Symptoms/Effects: Irritation of skin, eyes, respiratory system; possible metal fume fever with prolonged exposure.
Extinguishing Media: Use dry chemical powder, dry sand, or Class D extinguishers for metal fires; do not use water or foam.
Hazards from Combustion: Produces toxic oxides of copper and calcium; fumes and smoke may contain irritating or corrosive compounds.
Firefighter Protection: Wear full protective clothing and self-contained breathing apparatus; keep a safe distance from fire.
Special Procedures: Cool surrounding containers with dry agents if exposed to fire; contain runoff if possible.
Personal Precautions: Evacuate nonessential personnel; use personal protective equipment including gloves, goggles, and respirator if ventilation inadequate.
Environmental Precautions: Prevent entry into waterways, sewers, basements, or confined areas; notify authorities if material contaminates environment.
Containment Methods: Isolate spill area; scoop up spilled material into suitable containers using non-sparking tools.
Cleanup Procedures: Sweep or vacuum up material; avoid generating dust; dispose of in accordance with local regulations.
Disposal of Contaminated Material: Treat as hazardous waste; follow disposal considerations below.
Handling: Avoid contact with eyes, skin, and clothing; prevent dust or fume formation; use in a well-ventilated area; ground all equipment for static discharge.
Storage: Store in tightly closed containers in a cool, dry, well-ventilated area; keep away from acids, moisture, oxidizers, and combustible materials; segregate from incompatible substances.
Other Precautions: Use only tools and equipment rated for alloy handling; maintain good housekeeping to prevent accumulation of dust or scraps.
Exposure Limits: OSHA PEL for copper fume: 0.1 mg/m3; OSHA PEL for calcium metal: not established; consult ACGIH and NIOSH for guidance.
Engineering Controls: Local exhaust ventilation; enclosed handling systems where practical; eye wash stations and safety showers recommended.
Personal Protective Equipment: Protective gloves (nitrile, rubber), safety goggles or face shield, flame-resistant clothing, approved respirator if dust/fume present.
Hygiene Measures: Wash hands before eating or drinking; do not eat, drink, or smoke in work area; remove contaminated clothing immediately.

Boiling Point: Copper: 2562°C, Calcium: 1484°C (not directly relevant for alloy)
Density: 8.4–8.9 g/cm3
Solubility in Water: Insoluble
Vapor Pressure: Negligible at room temperature
pH: Not applicable
Flash Point: Not applicable
Evaporation Rate: Not applicable
Upper/Lower Flammability Limits: Not determined for alloy
Partition Coefficient (n-octanol/water): Not determined
Auto-ignition Temperature: Not applicable
Chemical Stability: Stable under recommended conditions of handling and storage
Reactivity: Reacts with strong acids; generates hydrogen gas when in contact with water or moisture; may react with oxidizers to create heat
Hazardous Reactions: Exposure to water may result in formation of flammable/explosive hydrogen gas
Hazardous Decomposition Products: Copper oxides, calcium oxides, hydrogen gas
Conditions to Avoid: Exposure to water or moisture; open flames; incompatible materials such as acids and oxidizers.
Acute Toxicity: Inhalation of dust or fumes can cause irritation to lungs and possible metal fume fever; ingestion may lead to nausea, vomiting, abdominal pain; skin and eye exposure causes irritation.
Chronic Effects: Prolonged or repeated exposure to copper dust or fumes may cause respiratory tract irritation, liver and kidney damage; calcium dust exposure may result in local tissue injury.
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Sensitization: Not a known sensitizer but may aggravate existing allergies or asthma.
Carcinogenicity: Copper and calcium are not classified as carcinogenic by IARC, NTP, or OSHA.
Reproductive Toxicity: No known reproductive hazards.
Target Organs: Respiratory system, skin, eyes, gastrointestinal tract.
Aquatic Toxicity: Toxic to aquatic life in both short- and long-term exposure due to copper solubility in water; calcium compounds may raise pH, impacting aquatic organisms.
Persistence and Degradability: Metallic copper and calcium are not biodegradable; persistent in environment.
Bioaccumulation Potential: Copper may accumulate in aquatic organisms; calcium less likely to bioaccumulate.
Soil Mobility: Limited mobility in soil; particles may remain near release point for extended periods.
Other Information: Do not allow material to enter drains, watercourses, or soil; authorities should be notified if environmental contamination occurs.
Waste Management: Dispose of in accordance with local, regional, national, and international regulations for hazardous waste.
Recommended Disposal Methods: Recycle material if possible via approved metal recyclers; unused material and process residues considered hazardous waste.
Containers: Empty containers retain product residues; handle with care and dispose through certified waste management companies.
