Storage & Handling

Recommended Storage
Cool, dry, well-ventilated area in compatible containers (lined steel, HDPE, FRP — verify per concentration). Segregate from bases, oxidizers, metals, and cyanides.Class-level guidance — not product-specific; the SDS controls.
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
Bases, active metals (aluminium, zinc), cyanides, sulfides, oxidizing agents. Reacts violently with organic anhydrides.Class-level guidance — not product-specific; the SDS controls.
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.
