Storage & Handling
- Recommended Storage
- Keep containers tightly closed in a cool, dry, well-ventilated place away from direct sunlight, acids and metals; protect from moisture (hygroscopic). Avoid raising dust.Adjudicated
- Handling Precautions
- Use standard chemical PPE — splash goggles, gloves, lab coat. Refer to SDS for hazard-specific PPE requirements.Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- Acids (violent exothermic reaction releasing carbon dioxide); aluminum and powdered aluminum; zinc and other metals; strong oxidizing agents; fluorine; water and moisture.Adjudicated
- Shelf Life
- 18 monthsnuroil.comStored moisture-free; after the expiry date the product should be re-tested and may be used further if it still complies. (Note: the sentence appears on a Soda Ash Dense data sheet but reads "Soda Ash light" as printed.)
For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
