Food‑sanitation grade available upon request. Compliance to
local food‑contact/sanitizer rules must be specified by the
buyer and will be confirmed on order.
| Applications | Packaging | Storage & Safety |
|---|---|---|
|
• Water & wastewater disinfection; shock chlorination.
• Food plant sanitation/CIP (where permitted); surface disinfection. • Cooling towers/industrial biocide; bleaching (textile/pulp) and odor control. |
• 25 L and 30 L HDPE jerricans; 200 L drums; 1,000 L IBCs;
bulk tank.
• Vented caps; UN/DG‑rated packaging; palletized & shrink‑wrapped. |
• Dangerous Goods — UN 1791 Class 8. Keep cool (5–25 °C),
shaded, and ventilated; protect from metals and organic
contaminants.
• **Do not mix with acids or ammonia.** Mixing with acids releases toxic chlorine gas. |
Use only according to local regulations and permits for the
intended application (e.g., drinking water limits and chlorate
specifications). For detailed handling, transport and PPE, follow
the SDS.
