Purity: Typically above 97% for industrial and research applications; impurities may include sodium salts, but these are typically below impurity reporting levels
Mixture or Pure Substance: Pure substance; bulk material does not contain additional hazardous additives according to supplier safety documentation
Stabilizers or Impurities: None commonly added intentionally, normal practice includes basic anti-caking agents below regulatory thresholds
Skin Contact: Immediately wash area with soap and water for several minutes, remove any contaminated clothing; seek medical attention if irritation persists
Eye Contact: Flush both eyes gently with plenty of water for ten to fifteen minutes, remove contact lenses if used, continue rinsing; medical advice should be sought for persistent discomfort
Inhalation: Move to fresh air, keep breathing calm and unlabored; if cough, discomfort, or irritation continue, professional medical help should be consulted
Ingestion: Rinse mouth, never induce vomiting unless directed by a medical professional; observe for symptoms of gastric distress or allergic reaction
Notes to Physician: Symptomatic treatment recommended; no specific antidote, supportive care based on symptoms and exposure assessment
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide can be used effectively on nearby combustibles
Specific Hazards: Combustion creates sulfur oxides, nitrogen oxides, and sodium oxides that can cause respiratory irritation; not expected to burn under normal warehouse fires, but can enhance toxic smoke
Protective Equipment for Firefighters: Wear full turnout gear with self-contained breathing apparatus
Firefighting Instructions: Keep containers cool with water spray to prevent rupture; minimize dust dispersion and runoff to storm sewers
Personal Precautions: Use chemical-resistant gloves, eye protection, and NIOSH-approved dust mask for large spills; ventilate area properly and avoid direct contact with substance
Environmental Precautions: Prevent large quantities from entering drainage, soil, or surface water; containment using absorbent inert material is widely effective
Cleanup Methods: Sweep or vacuum up, collect in sealable container for disposal; residue should be removed by wet wiping, avoiding dust formation
Special Procedures: Dispose material and contaminated cleanup supplies according to local regulations for laboratory or chemical waste
Precautions for Safe Handling: Handle powder or granules in well-ventilated areas; minimize dust formation by using personal protective equipment, and avoid skin, eye, or respiratory contact
Safe Storage Conditions: Store in tightly sealed containers, away from strong acids, strong oxidizers, and sources of ignition; maintain temperature between 15°C and 25°C, avoid humidity
Storage Incompatibilities: Acids (risk of decomposition and gas release), oxidizers, and reducers
Specific End Uses: Scientific research, chemical synthesis, not meant for food, drug, or cosmetic applications
Engineering Controls: Use local exhaust ventilation or fume hood; regular cleaning protocols to minimize dust accumulation
Exposure Limits: No occupational exposure limit values set by OSHA, ACGIH, or NIOSH as of last update; general dust limits may apply (<10 mg/m³ total); supplier recommendations suggest more stringent measures where excessive dust may occur
Personal Protective Equipment: Gloves made from nitrile or similar chemical-resistant material, splash-resistant safety glasses, and lab coat recommended during handling
Respiratory Protection: Dust mask or half-face respirator with particulate filter suitable for nuisance dust
Hygiene Measures: Regular handwashing after handling, separate eating and chemical handling spaces, prompt laundering of contaminated clothing
Appearance: Off-white to pale yellow crystalline powder
Odor: Odorless or faintly sweet
Odor Threshold: Not determined
pH: Slightly basic in aqueous solution (pH 7.5–9.0, 1% solution)
Melting Point/Freezing Point: No reliable data, decomposition may occur before melting
Boiling Point: Not applicable, decomposes before boiling
Flash Point: Not flammable by conventional testing
Evaporation Rate: Not relevant for solids
Flammability: Not a flammable material
Vapor Pressure: Negligible
Vapor Density: Not applicable
Solubility: Soluble in water; very limited solubility in most organic solvents
Partition Coefficient (n-octanol/water): Not determined
Auto-ignition Temperature: Not self-igniting
Decomposition Temperature: Estimated above 200°C
Viscosity: Not applicable to powders
Chemical Stability: Stable under normal ambient temperatures and pressures; sensitive to moisture over time (may clump, not hazardous)
Reactivity: Low reactivity with common materials; mild base
Conditions to Avoid: High humidity, excessive heat, open flames for bulk storage
Incompatible Materials: Strong acids (hydrolysis with possible gas evolution), oxidizing agents, ammonia-based chemicals
Hazardous Decomposition Products: Sulfur oxides, nitrogen oxides, sodium oxide fumes generated upon burning or intense heat
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: No known acute toxicity in animal studies for moderate single exposures; estimated LD50 (oral, rat) above 2000 mg/kg
Chronic Toxicity: No long-term exposure data in humans
Irritation: Mild to moderate irritation possible on contact with skin or eyes, rinsing usually sufficient
Sensitization: No reports on hypersensitivity reactions
Other Effects: Not mutagenic or carcinogenic based on available related compounds
Target Organs: Data not available for repeated exposure; normal precautions cover unknown risks
Eco-Toxicity: No measured aquatic toxicity data available; expected low toxicity to aquatic life at common concentrations
Persistence and Degradability: Compound expected to break down under natural environmental conditions; hydrolysis and basic microbial breakdown typical
Bioaccumulative Potential: Low—structural analysis suggests minimal potential for bioaccumulation
Mobility in Soil: Moderate mobility expected due to water solubility
Other Adverse Effects: No evidence of long-range environmental hazards, but chemical hygiene should keep releases to a minimum
Waste Treatment Methods: Treat as non-hazardous inorganic waste where local laws permit; incinerate or landfill in controlled manner through licensed facility
