Precautionary Statements: Avoid generating and breathing dust, use personal protective equipment where necessary
Pictogram: None required under GHS
Signal Word: None
Potential Health Effects: Eye and respiratory irritation from airborne dust; symptoms may include watery eyes, coughing, sneezing
Chemical Name: Calcium Carbonate
CAS Number: 471-34-1
Content: More than 98% calcium carbonate by weight
Impurities: May contain trace amounts of magnesium carbonate and silica depending on source and processing
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, remove contact lenses if present and easy to do; seek medical attention if irritation persists
Skin Contact: Wash affected area thoroughly with mild soap and water; remove contaminated clothing and wash before reuse
Inhalation: Move exposed person to fresh air; seek medical help if coughing or difficulty breathing persists
Ingestion: Rinse mouth with water; typically non-toxic in small quantities, but seek medical advice if large amounts have been swallowed or if adverse reactions occur
Note to Physician: Treat symptomatically
Suitable Extinguishing Media: Use standard media such as water spray, dry chemical, foam, or carbon dioxide
Specific Hazards: Calcium carbonate is non-flammable, does not contribute to combustion
Thermal Decomposition: Above 825°C, releases carbon dioxide gas and forms calcium oxide
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective clothing
Hazardous Combustion Products: None under normal storage and handling; if exposed to extreme heat, carbon dioxide may be released
Spill or Leak Procedures: Avoid generating airborne dust; sweep or shovel material into suitable container for reuse or disposal
Environmental Precautions: Prevent material from entering drains, watercourses, or soil in excessive amounts
Personal Precautions: Wear dust mask, goggles, gloves; ventilate area
Methods for Cleanup: Use wet methods or vacuum equipped with HEPA filter to minimize dust; avoid dry sweeping of large spills
Handling: Minimize dust creation during transfer and storage; ensure good ventilation in processing areas; avoid inhalation and contact with eyes or skin
Storage: Store in tightly closed containers in cool, dry, well-ventilated area away from strong acids; take measures to prevent moisture absorption and caking
Incompatible Materials: Strong acids (generates carbon dioxide), ammonium salts
Specific Requirements: Use only clean, dry equipment; keep away from food and feedstuffs
Occupational Exposure Limits: OSHA PEL (Total dust): 15 mg/m3; ACGIH TLV (Inhalable): 10 mg/m3
Engineering Controls: Use local exhaust or general ventilation to keep airborne concentrations below permissible limits
Respiratory Protection: Dust mask or respirator for concentrations above occupational exposure limits or in confined spaces
Eye Protection: Safety goggles or face shield where dust hazard exists
Skin Protection: Gloves and long sleeves advised to reduce skin contact
General Hygiene: Wash hands thoroughly after handling; do not eat, drink, or smoke in work areas
Appearance: Fine white to off-white powder or crystalline solid
Odor: Odorless
pH (in water): Typically 9.5 (10% suspension)
Melting Point: Decomposes above 825°C
Boiling Point: Not applicable
Solubility in Water: Poorly soluble (<0.0013 g/100 mL at 25°C)
Vapor Pressure: Not applicable
Specific Gravity: Approximately 2.7 (water = 1)
Flash Point: Not flammable
Evaporation Rate: Not applicable
Partition Coefficient (n-octanol/water): Not available
Other Properties: Stable under normal storage conditions
Chemical Stability: Stable under recommended storage conditions
Conditions to Avoid: Exposure to acids, humidity, excessive heat
Incompatible Materials: Contact with strong acids produces carbon dioxide; avoid mixing with ammonium salts
Hazardous Decomposition Products: Carbon dioxide released at high temperatures
Reactivity/Polymerization: Does not undergo hazardous polymerization
Acute Toxicity: Not considered toxic; high dust exposure can cause temporary respiratory or eye irritation
Chronic Toxicity: Prolonged inhalation may aggravate existing respiratory conditions
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, OSHA
Mutagenicity: No evidence of genetic damage in relevant studies
Reproductive Effects: Not known to cause reproductive harm
Routes of Exposure: Inhalation of dust, contact with eyes and skin, ingestion
Symptoms: Coughing, sneezing, mild eye and skin irritation
Ecotoxicity: Expected to have minimal environmental impact in normal use; not toxic to aquatic or terrestrial organisms
Mobility: Not significantly mobile in soil or water
Persistence and Degradability: Stable and not readily degradable; remains in environment as carbonate mineral
Bioaccumulation: No evidence of bioaccumulation in aquatic organisms
Other Adverse Effects: Excessive quantities may alter soil pH; avoid large uncontrolled releases
Waste Disposal Methods: Dispose in accordance with local, regional, and national regulations; can often be recycled or reused depending on contamination levels
