Storage & Handling
- Recommended Storage
- Keep tightly closed in acid-resistant containers in a cool, dry, ventilated area, away from water, bases, organics and metals. To dilute, add the acid slowly to water while stirring; never add water to the acid.Adjudicated
- Handling Precautions
- Use full PPE including face shield, acid-resistant gloves and apron. Add acid to water slowly with stirring; never reverse. Ventilation required.Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- Water (violent reaction with heat and spattering); bases; organic and combustible materials; reducing agents; chlorates, permanganates, nitrates, picrates, fulminates and carbides; cyanides and sulfides (release toxic gases); powdered metals and most metals (release flammable hydrogen).Adjudicated
- Shelf Life
- Consult Technical Services for product-specific shelf life
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.
