Health Hazards: May cause eye or respiratory irritation if inhaled, excessive ingestion may cause gastrointestinal discomfort
Environmental Hazards: Not considered dangerous to the environment at typical use levels

Composition / Information on Ingredients

Chemical Name: Sodium Bicarbonate
Synonyms: Baking soda, bicarbonate of soda
Concentration: 99% - 100%, food grade purity
Impurities: Small amounts of sodium carbonate, moisture possible by specification

First Aid Measures

Inhalation: Move to fresh air if dust inhaled, rinse mouth, seek medical attention if irritation persists
Skin Contact: Wash skin thoroughly with soap and water
Eye Contact: Rinse eyes immediately with water for at least 15 minutes, remove contact lenses, seek medical advice for discomfort
Ingestion: Rinse mouth with water, do not induce vomiting, consult medical attention for large ingestion or symptoms

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, foam, dry chemical or carbon dioxide
Specific Hazards: Substance does not burn, may decompose at high temperature to release carbon dioxide, poses suffocation risk in confined spaces
Protective Equipment: Firefighters should use standard protective gear and self-contained breathing apparatus
Special Instructions: No special procedures needed beyond routine fire response

Accidental Release Measures

Personal Precautions: Avoid inhaling dust, ensure good ventilation, wear protective clothing and goggles
Environmental Precautions: Prevent large amounts from entering drains or waterways
Spill Cleanup Methods: Sweep up material carefully to prevent dust formation, shovel into containers for disposal, rinse area with water if needed

Handling and Storage

Safe Handling: Avoid generating dust, handle with clean, dry hands or utensils, wash hands after use
Storage Conditions: Store in cool, dry, well-ventilated area, in tightly closed containers, away from acids and moisture
Incompatible Materials: Acids, strong oxidizers, aluminum powder
Specific Uses Noted: Food ingredients, cleaning, pharmaceuticals as per appropriate good practices

Exposure Controls and Personal Protection

Control Parameters: No established workplace exposure limits for sodium bicarbonate
Engineering Controls: Use local exhaust or general ventilation to control dust
Personal Protective Equipment:

  • Respiratory Protection: Approved dust mask for large-scale handling or when dust occurs
  • Eye Protection: Safety goggles recommended during bulk handling
  • Skin Protection: Protective gloves suggested for prolonged exposure
  • Hygiene Measures: Wash hands before eating and after handling, keep work clothes separate if handling bulk material

Physical and Chemical Properties

Stability and Reactivity

Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Reacts with acids to release carbon dioxide gas
Hazardous Reactions: Contact with acids causes rapid evolution of carbon dioxide; may react with aluminum at high temperatures
Decomposition Products: Above 50°C, forms sodium carbonate, water, carbon dioxide

Toxicological Information

Acute Toxicity: Low toxicity, oral LD50 (rat) > 4,220 mg/kg
Inhalation: Dust may cause mild irritation to respiratory tract
Skin Contact: Generally non-irritating
Eye Contact: Mild, temporary irritation possible with dust exposure
Chronic Effects: No known long-term health effects from usual exposure
Carcinogenicity: Not classified as carcinogen by IARC, NTP, OSHA
Other Data: Non-toxic at levels used in food, large ingestion may upset electrolyte balance

Ecological Information

Ecotoxicity: No evidence of significant toxicity to aquatic life at reasonable concentrations
Mobility: Dissolves readily in water, may increase local alkalinity
Persistence and Degradability: Inorganic compound, does not bioaccumulate or persist
Bioaccumulative Potential: Not bioaccumulative
Other Adverse Effects: Large releases may alter pH of waterways, consultation with regulators recommended for bulk discharges

Disposal Considerations

Waste Treatment Methods: Dispose of in accordance with local, regional, and national regulations
Product Disposal: Small quantities can go to sewer with water, larger batches to landfill following regulatory guidance
Packaging: Rinse containers before recycling or disposal, avoid contaminating land and water
