(a)General requirements. All chemicals used in pools and/or spray grounds shall be handled and stored in accordance with manufacturers' recommendations and applicable law. Only chemicals used by the United States Environmental Protection Agency, specified as food additives by the United States Food and Drug Administration as potable use approved by NSF, or by the State Commissioner of Health, shall be used. Each chemical shall be kept covered and stored in the original, labeled container with the identity of the chemical and appropriate hazard warnings clearly labeled, away from flame and heat sources, and in a clean, dry, well-ventilated place which prevents unauthorized access to the chemicals. The facility shall maintain the manufacturer's instructions for all chemicals in the facility.
(b)Mixing. When mixing a chemical solution the pool operator shall mix the chemical in water. Each chemical or chemical solution shall be separately applied. Chemicals shall not be combined or mixed together prior to application. Clean inert materials shall be used for container and mixing tools, and mixing shall be done by pouring the chemical into water. Mixing shall not be accomplished by pouring water into the chemical.
(c)Method. The method for addition of pool water treatment chemicals shall be specified in the pool safety plan. The method of chemical addition shall protect the patron from contact with concentrated chemicals. The method shall provide adequate distribution of the chemical throughout the pool and distribution shall be verified by pool water testing prior to bather exposure.
(d)Smoking. Smoking shall be prohibited in the chemical storage area or by anyone who is handling chemicals.
(e)Carbon dioxide (CO2 ). CO2 cylinders should be stored in a protective enclosure at the exterior of occupied structures. CO2 cylinders used in the interior of occupied structures shall be placed only in a ventilated enclosure pursuant to 24 RCNY Health Code § 165.47.
(f)Hypochlorite. Hypochlorite shall be used with extreme caution during handling or mixing. When using calcium hypochlorite, the pool operator shall not mix or contaminate the hypochlorite with organic matter or any foreign material (such as household products, soap products, ammonia, paint products, solvents, acids, vinegar, or dirty rags) which may result in fire or decomposition explosion.
