Combustion Products: Sulfur oxides, nitrogen oxides, sodium oxide, carbon monoxide, carbon dioxide
Personal Precautions: Evacuate area not involved in containment; wear chemical-resistant gloves, protective eyewear, and dust mask or respirator
Environmental Precautions: Avoid entry to drains, water bodies, or soil; contain any run-off with absorbent non-combustible material (vermiculite, sand)
Cleanup Methods: Collect spilled material using spark-proof tools and dispose in proper chemical waste container; ventilate area well
Decontamination: Wash spill site with mild detergent and water after collection
Follow-Up: Report larger releases to regulatory bodies per local requirements
Handling Guidelines: Use only in a well-ventilated environment; avoid creating dust clouds; ensure containers are tightly closed during use
Storage Recommendations: Store in original, clearly labeled containers; keep in cool, dry, well-ventilated area away from acids, oxidizers, moisture
Special Notes: Keep product away from food, drink, and incompatible materials; handle only with proper PPE
Incompatible Materials: Strong acids, oxidizers, chlorinated compounds
Safe Practices: Use grounded equipment; wash hands after handling; avoid storing with household chemicals or bases
Exposure Limits: No established occupational exposure limits for this substance
Engineering Controls: Use fume hood, local exhaust ventilation, dust suppression systems
Personal Protective Equipment: Chemical splash goggles, gloves (nitrile or neoprene), long-sleeved lab clothing or coverall, dust mask (minimum N95 rated), safety footwear
Hygiene Measures: Wash thoroughly after handling, remove contaminated clothing and wash before reuse
Respiratory Protection: Respirator for dust in absence of adequate ventilation

Reactivity: Reacts with strong oxidizers; generates toxic gases with acids
Hazardous Decomposition Products: Sulfur dioxide, nitrogen oxides, carbon oxides, sodium compounds
Conditions to Avoid: High humidity, strong sunlight, open flames, incompatible chemicals
Polymerization: Not anticipated under recommended storage conditions
Likely Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Effects: Irritation to skin, eyes, and respiratory tract; ingestion results in gastrointestinal issues like nausea or diarrhea
Chronic Effects: Prolonged exposure increases risk of dermatitis, possible liver effects
Toxicity Data: Oral LD50 (rat): Estimated >2,000 mg/kg, due to limited studies
Skin Sensitization: Data lacking, treat as potential irritant
Carcinogenicity: No classification by IARC, NTP, or OSHA
Other Health Effects: Not classified as mutagenic or reproductive hazard on current evidence
Aquatic Toxicity: Toxic to fish, daphnia, and aquatic organisms; chronic effects likely on continuous exposure
Persistence/Degradability: Partially biodegradable, but slow under environmental conditions
Mobility in Soil: Highly mobile in water due to sodium salt character
Bioaccumulation: Low predicted potential based on water solubility
Other Adverse Effects: Potential risk for eutrophication in waterways from high sulfur and nitrogen release
Waste Treatment Methods: Dispose through licensed chemical waste contractor equipped to handle hazardous substances
Disposal of Packaging: Rinse thoroughly, then treat as hazardous waste; follow local laws for container recycling or incineration
Universal Guidelines: Do not discharge into surface waters, sewers, or soil; comply with local, regional, and national disposal regulations
