Comprehensive Guide: SDS for Sodium Thiosulfate – Everything You Need to Know

As a corporate purchasing manager or operations director in the USA, ensuring compliance with OSHA's Hazard Communication Standard (HazCom 2012) is non-negotiable when handling chemicals like sodium thiosulfate. That's where our detailed sds for sodium thiosulfate comes in. This Safety Data Sheet (SDS) for sodium thiosulfate provides all critical information on identification, hazards, handling, storage, and emergency procedures, formatted to GHS standards for seamless integration into your supply chain.

Sodium thiosulfate, chemically known as Na₂S₂O₃·5H₂O (pentahydrate form), is a versatile inorganic compound widely used in water treatment, photography, gold mining leaching, pharmaceutical antidotes for cyanide poisoning, and as a dechlorinator in aquariums and pools. Its CAS number is 10102-17-7, and EINECS is 233-788-1. But why is the Sodium Thiosulfate SDS so crucial? It outlines potential health hazards (e.g., skin and eye irritation from dust), physical hazards (non-flammable but may release toxic sulfur oxides when heated), and environmental considerations.

Section 1: Identification – Product identifier: Sodium Thiosulfate Pentahydrate. Recommended use: Analytical reagent, antidote, fixer in photography. Supplier: Shijiazhuang Standard IMP&EXP CO.,LTD., No.448 Heping West Road, Shijiazhuang, Hebei, China. Emergency contact: +86-311-67665117. This ensures traceability back to our ISO-certified facility.

Section 2: Hazard Identification – GHS classification: Not a hazardous substance or mixture under OSHA HazCom. Signal word: None. Hazard statements: Causes serious eye irritation (H319), May cause respiratory irritation (H335). Pictograms: Exclamation mark. Precautionary statements include wearing protective gloves/eye protection and washing thoroughly after handling. Our SDS is fully aligned with USA regulations, unlike generic imports that risk fines up to $14,502 per violation.

Section 3: Composition/Information on Ingredients – Pure sodium thiosulfate pentahydrate, 99% min purity. Impurities: Heavy metals <10ppm, iron <2ppm, ensuring pharmaceutical-grade quality for your operations.

Section 4: First-Aid Measures – Inhalation: Move to fresh air; Skin: Wash with water; Eyes: Rinse 15 minutes, seek medical attention; Ingestion: Rinse mouth, do not induce vomiting. Most important symptoms: Mild irritation. Notes for physician: Treat symptomatically.

Section 5: Fire-Fighting Measures – Non-combustible. Extinguishing media: Water spray, foam, CO2. Specific hazards: Decomposes above 300°C releasing SO2, SO3. Firefighters should use self-contained breathing apparatus.

Section 6: Accidental Release Measures – Personal precautions: Avoid dust formation. Environmental precautions: Prevent entry into drains. Methods: Sweep up, vacuum if no ignition risk. Our bulk packaging minimizes spills, reducing cleanup time by 40%.

Section 7: Handling and Storage – Handling: Use in ventilated areas, ground containers to prevent static. Storage: Cool, dry, well-ventilated, away from acids/oxidizers. Shelf life: 2 years under proper conditions.

Section 8: Exposure Controls/Personal Protection – No OSHA PEL, but recommended TWA 5mg/m³ dust. PPE: Safety glasses, gloves (nitrile), dust mask (N95). Engineering controls: Local exhaust ventilation.

Section 9: Physical and Chemical Properties – Appearance: Colorless crystals. Odor: Odorless. pH: 6.0-7.5 (10% solution). Melting point: 48°C (dehydrates). Solubility: 70g/100ml water @20°C. Density: 1.69 g/cm³.

Section 10: Stability and Reactivity – Stable under normal conditions. Incompatible: Strong acids (releases SO2 gas), iodine (decolorizes). Hazardous polymerization: None.

Section 11: Toxicological Information – Acute oral LD50 (rat): 3,875 mg/kg. Skin/eye irritant. No carcinogenicity, reproductive toxicity per IARC/OSHA.

Section 12: Ecological Information – Low toxicity to aquatic life (LC50 >100mg/L). Biodegradable. Not bioaccumulative (log Pow negative).

Section 13: Disposal Considerations – Dispose as non-hazardous waste per local regs. RCRA non-hazardous.

Section 14: Transport Information – UN number: None. Not regulated by DOT/IMDG/IATA.

Section 15: Regulatory Information – TSCA listed. SARA 313: No. California Prop 65: No. Complies with REACH, FDA for pharma uses.

Section 16: Other Information – Revision date: 2026. NFPA: Health 1, Flammability 0, Reactivity 0. Disclaimer: For professional use only.

Your Top Pain Points When Sourcing SDS for Sodium Thiosulfate

You face skyrocketing costs and compliance headaches. Here's why:

• High Prices: Competitors charge 30-50% premiums due to inefficient China's supply chains – your ROI suffers.
• Low Quality: Impure products (<98%) lead to failed batches, recalls costing $100K+ annually.
• High Shipping Costs: Slow ocean freight from unreliable sources adds $0.20/kg, delaying production.
• Non-Compliant SDS: Generic sheets ignore USA-specific OSHA/GHS updates, risking shutdowns.
• Unreliable Delivery: 4-6 week waits disrupt your operations timeline.
• Poor Support: No OEM/ODM options for custom grades.

Scenario: A Texas water treatment plant lost $50K from contaminated sodium thiosulfate. Don't let this happen to you.
