2. Hazard Identification

GHS Classification: Not considered hazardous under normal use and handling
Signal Word: None
Hazard Statements: May cause eye or skin irritation in sensitive individuals or under prolonged exposure
Precautionary Statements: Avoid inhalation of dust, minimize skin and eye contact, use only as directed with proper safety measures

3. Composition / Information on Ingredients

Chemical Name: Sodium Bicarbonate
Common Name: Baking Soda
Synonyms: Sodium hydrogen carbonate
Concentration: 99% or higher
Impurities: Minimal; trace levels of sodium carbonate, moisture

4. First Aid Measures

Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, seek medical attention if irritation persists
Skin Contact: Wash with plenty of soap and water, remove contaminated clothing, treat persistent irritation with medical evaluation
Inhalation: Move to fresh air, seek medical attention for breathing difficulty, provide oxygen if symptoms are severe
Ingestion: Rinse mouth, drink water to dilute, seek medical guidance in case of persistent discomfort or ingestion of large quantities

5. Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Specific Hazards from Chemical: Sodium bicarbonate does not burn but can degrade to sodium carbonate, water, and carbon dioxide under intense heat
Protective Equipment: Firefighters use self-contained breathing equipment, avoid inhalation of thermal decomposition products
Special Procedures: Cool exposed containers with water spray, ensure proper ventilation to prevent buildup of carbon dioxide gas

6. Accidental Release Measures

Personal Precautions: Use appropriate personal protective equipment such as gloves, safety glasses, dust mask
Environmental Precautions: Prevent entry to waterways or drainage systems as a large spill may increase local water alkalinity
Cleaning Methods: Sweep up spilled material, avoid dust generation, collect in suitable container for disposal or reuse, wash contaminated area with water

7. Handling and Storage

Safe Handling Instructions: Handle with care to prevent dust formation, do not ingest, minimize contact with skin and eyes, always wash hands after handling
Storage Requirements: Store in a cool, dry, well-ventilated place, keep containers tightly closed to maintain product quality, separate from acids and moisture sources
Incompatible Materials: Strong acids, acidic salts, ammonium compounds, and aluminum under certain conditions

8. Exposure Controls and Personal Protection

Occupational Exposure Limits: ACGIH recommends exposure limit for nuisance dust at 10 mg/m³ (total) and 3 mg/m³ (respirable fraction)
Engineering Controls: Ensure adequate local or general ventilation, especially during bulk transfer or mixing operations
Personal Protective Equipment: Safety glasses or goggles, dust mask or approved respirator for dusty conditions, chemical-resistant gloves for extended contact, protective clothing if handling large quantities

9. Physical and Chemical Properties

Appearance: White, crystalline powder
Odor: Odorless
Solubility: Soluble in water
pH: 8.3 (1% solution at 25°C)
Melting Point: Decomposes above 50°C (104°F)
Boiling Point: Not applicable
Vapor Pressure: Not applicable
Bulk Density: 1.0-1.2 g/cm³
Molecular Weight: 84.01 g/mol

10. Stability and Reactivity

Chemical Stability: Stable under normal dry, cool storage conditions
Reactivity: Reacts with acids, releasing carbon dioxide gas
Hazardous Reactions: May react with strong acids to produce heat and CO₂ gas, avoid moisture to prevent caking
Decomposition Products: Carbon dioxide, sodium carbonate, water vapor
Incompatibility: Acids, ammonium compounds, certain metals such as aluminum in the presence of moisture

11. Toxicological Information

Acute Toxicity: Low toxicity, oral LD₅₀ in rats: 4220 mg/kg
Skin and Eye Contact: May cause irritation from prolonged or repeated contact
Inhalation Exposure: Dust may cause respiratory irritation, symptoms include coughing or sneezing
Long-Term Exposure: Chronic exposure unlikely to cause significant health issues, though sensitive persons may experience irritation
Carcinogenicity: Not considered a carcinogen by IARC, OSHA, or NTP

12. Ecological Information

Ecotoxicity: Generally low risk to aquatic life at typical feed-grade concentrations, high releases could alter local water pH
Mobility: Dissolves and disperses readily in water
Persistence and Degradability: Degrades into naturally occurring substances (CO₂, water, sodium carbonate)
Bioaccumulation: Not bioaccumulative
Environmental Fate: Rapidly converted in the natural environment, avoid uncontrolled release to minimize pH disruption

13. Disposal Considerations

Waste Treatment Methods: Handle as non-hazardous waste, where allowed, dispose of in accordance with local, regional, and national regulations
Recommended Disposal: Landfill or controlled industrial waste site; can also be dissolved in water and flushed to sewer if approved by environmental authorities
Packaging Disposal: Recycle or dispose of empty packaging following local requirements, avoid reuse for food or animal feed containers unless thoroughly cleaned

14. Transport Information

UN Number: Not regulated for transport
Transport Hazard Class: Non-hazardous material
Packing Group: Not applicable
Proper Shipping Name: Sodium Bicarbonate, Feed Grade
Special Precautions: Prevent damage to packaging during transport, keep dry and sealed to prevent caking or contamination

15. Regulatory Information

TSCA Status: Listed
REACH Status: Registered
OSHA Status: Not classified as hazardous
GHS Compliance: Not dangerous goods; no specific labeling required beyond general safety precautions
Other Applicable Regulations: Meets feed additive regulations in many countries; ensure compliance with local agricultural, environmental, and occupational safety rules before distribution or use
