Material Safety Data Sheet: Sodium Bicarbonate Industrial Grade

1. Identification

Product Name: Sodium Bicarbonate Industrial Grade
Common Names: Baking soda, Bicarbonate of soda
CAS Number: 144-55-8
Recommended Use: Industrial applications including water treatment, chemical manufacturing, food processing, cleaning
Manufacturer Information: [Contact details provided by supplier]
Emergency Contact Number: Refer to supplier information or local emergency service.

2. Hazard Identification

Classification: Not classified as hazardous under GHS for most uses
Physical Hazards: May produce dust; slips possible due to spills
Health Hazards: May cause mild irritation to eyes and skin; inhalation of dust could lead to mild respiratory symptoms
Environmental Hazards: Large quantities in waterways may raise pH and disrupt aquatic habitats
Label Elements: Not classified as a dangerous substance, so no standard pictogram or signal word required

3. Composition / Information on Ingredients

Chemical Name: Sodium Bicarbonate
Synonyms: Baking soda, sodium hydrogen carbonate
Formula: NaHCO₃
Purity: Typically greater than 99%
Impurities: Traces of sodium carbonate or sodium chloride may be present depending on source

4. First Aid Measures

Inhalation: Move person to fresh air; seek medical attention for persistent symptoms
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes
Skin Contact: Rinse skin with water; remove contaminated clothing
Ingestion: Rinse mouth with water; if discomfort persists, consult a healthcare professional

5. Fire-Fighting Measures

Suitable Extinguishing Media: Use extinguishing method suitable for surrounding fire; sodium bicarbonate itself is not flammable
Special Hazards: Releases carbon dioxide (CO₂) when heated, which may contribute to confined space pressure buildup
Protective Equipment: Firefighters should wear standard protective clothing with self-contained breathing apparatus in occupational fires

6. Accidental Release Measures

Personal Precautions: Avoid generating dust; wear dust mask and protective eyewear
Environmental Precautions: Prevent bulk discharge to drains or surface water, particularly in sensitive aquatic areas
Clean-up Methods: Sweep up material, avoid dry sweeping if large volumes are present; use a vacuum fitted with HEPA filter for dust; place recovered material in proper containers for reuse or disposal

7. Handling and Storage

Handling: Avoid breathing dust; use with adequate ventilation; minimize dust creation; wash thoroughly after handling
Storage Conditions: Store in dry, cool, well-ventilated area; keep containers tightly closed; avoid contact with acids; separate from incompatible materials such as strong acids

8. Exposure Controls and Personal Protection

Exposure Limits: No specific occupational exposure limit assigned; general particulate limits may apply
Engineering Controls: Use general or local exhaust to control airborne dust; provide eye wash stations where heavy use occurs
Personal Protective Equipment: Wear safety goggles, gloves, and dust mask or respirator (if exposure is likely to exceed general dust limit); use protective clothing as needed

9. Physical and Chemical Properties

Appearance: White, crystalline powder
Odor: Odorless
pH (1% solution): 8.2 – 8.6
Melting Point: Decomposes above 50°C
Boiling Point: Not applicable
Solubility in Water: Moderately soluble; approximately 96 g/L at 20°C
Specific Gravity: 2.2 g/cm³
Vapor Pressure: Not applicable
Partition Coefficient: Log P not relevant for ionic substances

10. Stability and Reactivity

Chemical Stability: Stable under recommended conditions
Reactivity: Reacts with acids to release carbon dioxide gas; incompatible with strong acids; avoid prolonged exposure to heat or moisture
Hazardous Decomposition Products: Carbon dioxide, sodium carbonate

11. Toxicological Information

Acute Toxicity: Oral LD₅₀ (rat): 4220 mg/kg; low toxicity
Skin Corrosion/Irritation: Not a skin irritant at typical concentrations
Eye Damage/Irritation: May cause mild eye irritation
Sensitization: Not classified as a skin or respiratory sensitizer
Chronic Effects: Data available does not indicate significant chronic health risks
Carcinogenicity: Not listed by IARC, NTP, or OSHA
Mutagenicity: Not mutagenic based on current studies

12. Ecological Information

Ecotoxicity: Large quantities may affect aquatic life by changing the pH of water bodies
Persistence and Degradability: Readily dissociates in water to naturally occurring ions
Bioaccumulation Potential: Not expected to bioaccumulate
Mobility in Soil: High mobility due to solubility in water
Other Adverse Effects: No known long-term threat in usual usage; maintaining normal concentrations is important for environmental balance

13. Disposal Considerations

Waste Treatment Methods: Dispose of excess or waste through landfill or approved waste facility
Procedures: Avoid disposing large quantities into water sources; follow local regulations for non-hazardous waste; reuse or recycle where possible

14. Transport Information

UN Number: Not regulated as hazardous for transport
Transport Hazard Class: Not assigned
Packing Group: Not assigned
Special Precautions: Protect from moisture; keep in closed containers during transport to prevent contamination or caking
Labeling: No special labeling required under international road, sea, or air transport regulations

15. Regulatory Information

Inventory Listing: Listed on TSCA (USA), EINECS/ELINCS (EU), DSL (Canada), and other global inventories
Regulatory Status: Not classified as hazardous under OSHA, GHS, or EU REACH; food grade has additional regulatory controls
Other Regulations: Compare local workplace safety and environmental requirements; monitor for occupational exposure dust limits under national guidelines
