Hasa Pool Acid is used to reduce pH of waters in swimming pools, spas, hot tubs, and recreational waters. It is a
solution of sulfuric acid in water. Sulfuric acid is listed as a toxic chemical at 40 CFR 372.65 under Part 372, 鈥淭oxic
Chemical Release Reporting 鈥? Community Right-to-Know,鈥? regulations promulgated pursuant to Section 313 Title III of
the Superfund Amendments and Reauthorization Act of 1986 [42 U.S.C. 11023 and 11048]. This product is excluded
