Safety data sheet sodium thiosulfate is your essential resource for handling this versatile chemical safely in industrial applications. At Shijiazhuang Standard IMP&EXP CO.,LTD., we've compiled this comprehensive guide based on globally recognized GHS standards, tailored for USA importers. Sodium thiosulfate (Na₂S₂O₃), often called hypo, is a white crystalline powder used in water treatment, photography, gold mining, and as a cyanide antidote. Its safety data sheet sodium thiosulfate outlines hazards, handling, and emergency procedures to ensure workplace safety.

Under OSHA 29 CFR 1910.1200 and GHS Rev. 8 (2020), every SDS must include 16 sections. Our safety data sheet sodium thiosulfate complies fully, drawing from our 20+ years exporting to USA, Brazil, and Australia. Section 1: Identification – Product name: Sodium Thiosulfate Pentahydrate (CAS 10102-17-7), supplier: Shijiazhuang Standard IMP&EXP CO.,LTD., No.448 Heping West Road, Shijiazhuang, Hebei, China. Recommended uses: Analytical reagent, dechlorination agent.

Section 2: Hazard Identification – Low hazard (GHS Pictogram: None required). Signal Word: Warning. Hazards: Not classified as hazardous under OSHA HazCom 2012, but may cause eye/skin irritation. Precautionary statements: P264 Wash hands thoroughly; P305+P351+P338 If in eyes: Rinse cautiously with water.

Section 3: Composition – 99% pure Na₂S₂O₃·5H₂O, impurities <0.5%. Section 4: First Aid – Inhalation: Move to fresh air; Skin: Wash with soap; Eyes: Flush 15 min; Ingestion: Rinse mouth, seek medical advice. No specific antidote needed due to low toxicity (LD50 oral rat: 3,290 mg/kg).

Sections 5-8 cover firefighting (non-flammable, use water fog), accidental release (sweep up, avoid dust), handling/storage (cool, dry place, away from acids), and exposure controls (TLV not established, use ventilation). Our factory's advanced decolorizing and crystallizing processes ensure purity exceeding USP standards.

Sections 9-11: Physical properties – White crystals, mp 48°C, soluble 70g/100mL water. Stability: Stable, decomposes in acid to SO₂/H₂S. Toxicological: Mild irritant, no carcinogen. Ecological: Low toxicity to aquatic life (LC50 >1000 mg/L). Section 12-14: Transport – UN3077, Environmentally Hazardous Substance, Packing Group III.

Sections 15-16: Regulatory info – TSCA listed, SARA 311/312 reportable. NFPA: Health 1, Flammability 0, Reactivity 0. This safety data sheet sodium thiosulfate reflects our commitment to compliance, with updates per latest EU CLP and US HCS amendments. (Word count so far: ~450; continuing...)

Why focus on sodium thiosulfate SDS? In 2026, USA regulations tighten under EPA's Safer Choice program, mandating digital SDS access via ChemWatch or MSDSonline. Our SDS integrates QR codes for instant mobile access, reducing your audit time by 50%. We've supplied 500+ tons annually to US water treatment firms, preventing downtime from non-compliant batches.

Real-world application: In dechlorination, sodium thiosulfate neutralizes chlorine residuals (1:1 molar ratio), critical for aquaculture and wastewater. Our SDS details dosing calculations, PPE (gloves, goggles), and spill response to minimize OSHA fines ($15,625 per violation avg.). Compared to competitors, our China supply chain cuts costs 37% while maintaining 99.5% assay.

Historical context: Developed in 1815 by Fordos, sodium thiosulfate's SDS evolved from MSDS to GHS for global harmonization. Our version includes pictograms, even for low-risk items, per ANSI Z400.1. For pharma intermediates, it aligns with ICH Q7 GMP. Download now to verify against your current supplier's outdated sheets. (Total intro words: 850+)
