Applications
Chlorine dioxide generation for water treatment and disinfection; laboratory oxidizer and reagent.Adjudicated
Restrictions on Use: For trained industrial users only. Strong oxidizer: never mix with acids (releases toxic, explosive chlorine dioxide gas), combustibles, organics or reducing agents. Contaminated clothing can ignite.
Storage & Handling
- Recommended Storage
- Keep tightly closed in a cool, dry, well-ventilated area, separated from acids, combustibles, reducing agents and organics. Do not store on wooden pallets. Store locked up.Adjudicated
- Handling Precautions
- Use PPE including face shield, chemical-resistant gloves, and apron. Avoid contamination — never return unused material to the original container. Ground all transfer equipment.Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- Acids (release chlorine dioxide, toxic and explosive); reducing agents; combustible and organic materials, oils and solvents; finely powdered metals; hypochlorites; ammonium compounds.Adjudicated
