Chemical Name: Sodium Tetraborate Decahydrate
Concentration: 99-100%
CAS Number: 1303-96-4
Impurities: Less than 1% trace impurities not classified as hazardous
Inhalation: Move affected person to fresh air, loosen any tight clothing, seek medical advice if symptoms persist such as coughing, wheezing, or shortness of breath
Skin Contact: Wash skin with plenty of water and soap, remove contaminated clothing, seek medical attention if irritation or rash develops
Eye Contact: Rinse cautiously with water for at least 15 minutes while holding eyelids open, remove contact lenses before rinsing, continue rinsing, seek medical evaluation for persistent irritation or pain
Ingestion: If swallowed, rinse mouth with water, do not induce vomiting, drink water to dilute if conscious, seek immediate medical help for large quantities or persistent symptoms
Suitable Extinguishing Media: Water spray, dry chemical powder, foam, carbon dioxide; cool containers with water spray to prevent bursting if exposed to flames
Unsuitable Media: None known for sodium tetraborate
Specific Hazards: Non-flammable, does not emit flammable vapors; at high temperatures, may emit irritating or toxic fumes such as boron oxides
Protective Equipment for Firefighters: Full protective gear and self-contained breathing apparatus recommended in case of fire involving nearby combustibles
Firefighting Instructions: Avoid breathing dust or fumes, isolate area and keep out unnecessary personnel; cool exposed containers
Personal Precautions: Use dust mask, chemical-resistant gloves, eye protection, avoid contact with skin and eyes, ventilate area
Spill Containment: Avoid generating airborne dust, sweep up carefully and place in labeled containers, avoid uncontrolled release into sewage, soil, or waterways
Clean-Up Methods: Vacuum or wet-sweep for large spills, wash spill site after material pickup, prevent further release or spread
Disposal: Dispose of collected material according to local, national, or regional environmental regulations
Safe Handling Instructions: Avoid dust generation and inhalation, do not eat or drink while handling, wash thoroughly after use, use only with adequate ventilation
Storage Recommendations: Store in tightly closed containers, keep in a cool, dry, well-ventilated area, avoid exposure to moisture or water, store away from acids
Technical Measures: Use appropriate containers to prevent moisture ingress and maintain product integrity
Incompatible Materials: Acids and strong oxidizing agents, which may generate heat or hazardous gases
Exposure Limits: OSHA PEL: 10 mg/m3 (total dust), 5 mg/m3 (respirable fraction); ACGIH TLV: 2 mg/m3 (inhalable borate dust)
Engineering Controls: Local exhaust ventilation, process enclosures, dust collection systems to control airborne dust
Personal Protective Equipment: Dust mask or respirator (for high dust levels), chemical-resistant gloves (nitrile, neoprene), safety goggles, protective clothing as needed
Hygiene Measures: Wash hands and face after handling, change contaminated clothing, do not use near food or beverages
Appearance: White, odorless crystalline solid or powder
Odor: Odorless
Solubility in Water: Soluble (approx. 50 g/L at 20°C)
pH (1% solution): About 9.2
Melting Point: 741°C (anhydrous), dehydrates at lower temperatures
Boiling Point: Decomposes before boiling
Vapor Pressure: Not applicable (non-volatile)
Density: Approximately 1.7 g/cm3 (decahydrate)
Flash Point: Not flammable
Chemical Stability: Stable under recommended storage and handling conditions
Thermal Decomposition: May decompose at high temperatures to boron oxides and water
Reactivity: Reacts with strong acids to release boric acid and heat
Conditions to Avoid: Moisture, exposure to acids, prolonged exposure to air, excessive heat
Incompatible Materials: Acids, strong oxidizers
Hazardous Decomposition Products: Boron oxides, sodium oxide fumes if heated to decomposition
Acute Toxicity: Oral LD50 (rat): about 2660 mg/kg; skin and eye irritation possible
Chronic Toxicity: Repeated or prolonged exposure by inhalation or ingestion may affect reproductive organs, possible influence on fertility with long-term exposures above regulatory limits
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Symptoms of Overexposure: Eye redness, burning sensation, dry or cracked skin, stomach upset with high amounts ingested
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, OSHA
Mutagenicity/Teratogenicity: Classified as possible hazard to fertility or unborn child with significant, long-term exposure
Aquatic Toxicity: Moderately toxic to aquatic life in high concentrations; aquatic LC50 for fish: approximately 100-200 mg/L
Persistence and Degradability: Borates occur naturally, do not degrade rapidly, and move through soil and water
Bioaccumulation: Not expected in aquatic organisms
Mobility in Soil: Water soluble, readily moves with runoff
Other Ecological Effects: Plants exposed to high levels may show growth inhibition; significant soil release can alter pH
