Classification: Not considered hazardous according to OSHA Hazard Communication Standard
Signal Word: None
Pictograms: None required
Hazard Statements: May irritate eyes or respiratory tract with prolonged contact
Precautionary Statements: Avoid breathing dust, prevent eye and skin contact, practice good hygiene..
Potential Health Effects: Inhalation may cause mild respiratory irritation, ingestion might upset gastrointestinal tract, contact with eyes or skin can cause minimal irritation in sensitive individuals
Chemical Name: Calcium Bicarbonate
Common Name: Calcium hydrogen carbonate
CAS Number: 5743-26-0
Concentration: Pure or as indicated on product label
Impurities: Typical grades may contain trace amounts of magnesium, sodium, or potassium salts
Inhalation: Move to fresh air, provide oxygen if breathing is difficult, seek medical attention for persistent symptoms
Skin Contact: Wash area thoroughly with plenty of water and mild soap, remove contaminated clothing
Eye Contact: Rinse eyes gently for at least 15 minutes under running water, keep eyelids apart, seek attention if irritation persists
Ingestion: Rinse mouth, drink water to dilute, do not induce vomiting, seek medical oversight if large quantity consumed or symptoms appear
Notes to Physician: Treat symptomatically, check for signs of respiratory distress
Suitable Extinguishing Media: Product is not flammable; use media appropriate for surrounding fire, such as water spray, dry chemical, or CO2 foam
Unsuitable Extinguishing Media: None known; avoid direct stream on spilled material
Special Hazards: At high temperatures, decomposition releases carbon dioxide gas; excessive CO2 in enclosed spaces can cause suffocation
Protective Equipment for Firefighters: Wear standard protective gear and self-contained breathing apparatus
Personal Precautions: Avoid breathing dust, ventilate area, use appropriate PPE including dust mask, gloves, and goggles
Environmental Precautions: Prevent large amounts from entering drains, waterways, or soil; dilute with plenty of water if spillage is accidental and minimal
Clean-up Procedures: Sweep up material carefully, avoid dispersing dust, dispose in suitable waste container, rinse residues with water
Safe Handling: Minimize dust generation, avoid unnecessary contact, store chemical in a well-ventilated area, maintain proper labels and segregation from incompatible materials
Storage Conditions: Keep container tightly closed, avoid exposure to moisture and acidic vapors, store at room temperature in a dry, cool, well-ventilated location away from acids
Incompatibilities: Avoid contact with strong acids as it causes decomposition and release of carbon dioxide gas
Exposure Limits: No specific occupational exposure limits established for calcium bicarbonate
Engineering Controls: Use local exhaust or general ventilation to control airborne dust
Personal Protection: Wear safety glasses, gloves, and dust mask for normal use; for large-scale handling, use chemical-resistant clothing and positive pressure respiratory protection if ventilation is inadequate
General Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing before breaks and after work
Appearance: White powder or colorless crystals in solution
Odor: Odorless
pH: Slightly alkaline in solution, typically 7.5-8.5
Melting Point: Decomposes before melting
Boiling Point: Not applicable
Solubility: Soluble in water (forms only in solution), insoluble as a dry solid
Density: Varies by concentration in solution
Vapor Pressure: Not applicable
Partition Coefficient: Not applicable
Decomposition Temperature: Releases CO2 on heating above 50°C
Chemical Stability: Stable under normal conditions in aqueous solution, decomposes on drying or heating
Reactivity: Reacts with acids to yield carbon dioxide and calcium salts
Hazardous Decomposition Products: Carbon dioxide
Conditions to Avoid: Freezing, excessive heat, drying, and acidic conditions
Incompatible Materials: Strong acids, strong oxidizers
Acute Toxicity: No significant acute toxicity data for calcium bicarbonate
Chronic Exposure: Prolonged or repeated exposure may lead to irritation in sensitive individuals
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Symptoms: Mild irritation to respiratory tract, nausea, vomiting, or diarrhea if ingested in large quantities
Carcinogenicity: Not considered carcinogenic
Additional Data: Not mutagenic, non-teratogenic
Ecotoxicity: Not expected to be hazardous to aquatic or terrestrial environments in small amounts
Environmental Persistence: Decomposes in water, contributing to natural mineral cycles
Bioaccumulation Potential: Not bioaccumulative
Mobility in Soil: Soluble in water, moderate mobility
Other Adverse Effects: High levels in water may increase alkalinity and hardness, affect pH balance, and impact some aquatic organisms
Disposal Methods: Dispose according to local, regional, and national regulations; small quantities can be diluted and flushed to drain with plenty of water if permitted by local authority
Container Disposal: Rinse containers before discarding or recycling, do not reuse for food or beverage storage
Waste Classification: Not classified as hazardous waste under most regulations
UN Number: Not regulated for transport
Shipping Name: Calcium Bicarbonate, non-hazardous
Transport Hazard Class: Not applicable
