Regulated Sanitizer/Oxidizer: Per the manufacturer SDS, this product is classified as a Sanitizer and Oxidizer water treatment chemical and is an EPA-registered pesticide product.
Installation & Compatibility
  • Storage Location: Store product tightly sealed in original containers in a cool, dry, well-ventilated area, away from combustible or flammable products.
  • Temperature Limits: Do not store where the average daily temperature exceeds 95°F, as storage above this temperature may result in rapid decomposition and evolution of chlorine gas.
