16、In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036. Copyright 2016 American Water Works Association. All Rights Reserved. viii Int

17、ernational (NSF*) to develop voluntary third-party consensus standards and a certification program for direct and indirect drinking water additives. Other members of the original consortium included the Water Research Foundation (formerly AwwaRF) and the Conference of State Health and Environmental

18、Managers (COSHEM). The American Water Works Association (AWWA) and the Association of State Drinking Water Administrators (ASDWA) joined later. In the United States, authority to regulate products for use in, or in contact with, drinking water rests with individual states. Local agencies may choose

19、to impose requirements more stringent than those required by the state. To evaluate the health effects of products and drinking water additives from such products, state and local agencies may use various references, including two standards developed under the direction of NSF: NSF/ANSI 60, Drinking

20、 Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. Various certification organizations may be involved in certifying products in accor- dance with NSF/ANSI 60. Individual states or local agencies have authority to accept or accredit certificati

21、on organizations within their jurisdictions. Accreditation of certi- fication organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 60 does not stipulate a maximum allowable level (MAL) of a contaminant for substances not regula

22、ted by a USEPA final maximum contaminant level (MCL). The MALs of an unspecified list of “unregulated contaminants” are based on toxicity testing guidelines (noncarcinogens) and risk characterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on the c

23、ertifier. ANSI/AWWA B603 addresses additives requirements in Sec. 4.3.2 of the standard. The transfer of contaminants from chemicals to processed water or to the residual sol- ids is becoming a problem of great concern. The language in Sec. 4.3.2 is a recommen- dation only for direct additives used

24、in the treatment of potable water to be certified by an accredited certification organization in accordance with NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects. However, users of the standard may opt to make this certification a requirement for the product. Users of this standard shou

25、ld also consult the appropriate state or local agency having jurisdiction in order to 1.

The products themselves are noncombustible but will accelerate the burning of combustible materials. They react wit

28、h many materials and care should be exercised in their handling, storage, and use. Therefore, contact with all combustible materials or chemicals must be avoided. These include but are not limited to wood, cloth, organic materials, and charcoal. Avoid contact with acids, peroxides, sulfites, oxalate

29、s, and other oxidizable inorganic chemicals. Permanganates should be segregated from ammonium compounds, metallic powders, phosphorus, hydrogen peroxide, carbon, metal hydrides, hydrazine, hydroxylamines, antifreeze, hydraulic oils, and formaldehyde. The products should be stored in a cool, dry area

30、 in closed containers and should be protected from physical damage. Concrete floors are preferred. Avoid wooden decks. Protect the liquid sodium permanganate solution from freezing. Spills of dry potassium permanganate should be swept up and transferred to clean metal drums and disposed of according

31、 to federal, state or provincial, and local reg- ulations. Spilled dry potassium permanganate should not be returned to the origi- nal drums that contain uncontaminated product. After the permanganate has been cleaned up, the residual permanganate on the floor should be flushed with water into a san

32、itary sewer, complying with federal, state or provincial, and local regulations. Spills of liquid sodium permanganate solution should be collected and disposed of properly. Contain and dilute spillage to approximately 6 percent with water and reduce the permanganate with sodium thiosulfate, sodium b

33、isulfite, or sodium metabisulfite. Deposit sludge in an approved landfill or, where permitted, flush into a sanitary sewer with large quantities of water. When handling either potassium permanganate or sodium permanganate, good safety procedures must be observed. These include the use of safety gogg

34、les, safety glasses with side shields, or face shields; impervious rubber or PVC gloves; and aprons. A NIOSHMSHA-approved respirator meeting general industry standards as described in ANSI/ASSE* Z88.2, American National Standard Practices for Respiratory Pro- tection, latest revision, is recommended

36、lothing becomes spotted when handling the liquid sodium permanganate, wash off immediately with large quantities of water. Permanganates are corrosive to the eyes and can cause severe burns. If exposed to permanganate, immediately flush the affected eye with water for 15 minutes while holding the ey

37、elid open. Consult a physician immediately. For additional safety aspects, refer to safety data sheets (SDSs) available from the chemical supplier or manufacturer. III. Use of This Standard. It is the responsibility of the user of an AWWA standard to determine that the products described in that sta

38、ndard are suitable for use in the particular application being considered. III.A. Purchaser Options and Alternatives. The fo llowing information should be provided by the purchaser: 1. Standard usedthat is, ANSI/AWWA B603, Permanganates, of latest revision. 2. Whether compliance with NSF/ANSI 60, Dr

39、inking Water Treatment ChemicalsHealth Effects, is required. 3. Quantity required. 4. Details of other federal, state or provincial, and local requirements (Sec. 4). 5. Grade desiredtechnical, free-flowing, or other dry crystals, or liquid solu- tion. Physical and chemical requirements are provided

40、in the standard for both the dry technical and free-flowing grades (Sec. 4.1.1) and the liquid products (Sec. 4.1.2). Chemical requirements for dry potassium permanganate are provided for technical and free-flowing grades (Sec. 4.2). If a grade other than technical, free-flowing, or liquid product i

41、s desired, the purchaser must specify the requirements of the grade desired. 6. Whether the purchaser will reject product from containers or packaging with missing or damaged seals. The purchaser may reject product from bulk containers or packages with missing or damaged seals unless the purchasers

42、tests of representative samples, conducted in accordance with Sec. 5.3, 5.4, and 5.5, demonstrate that the product meets the standard. Failure to meet the standard or the absence of, or irregu- larities in, seals may be sufficient cause to reject the shipment. 7. Form of shipmentbulk, container size
