38、 in this section are intended to protect food from contamination and ensure that the materials used in the manufacture of automatic ice making equipment resist wear, penetration by vermin, and the effects of foods, heat, cleaning compounds, sanitizers, and other substances that may contact the mater

39、ials in the intended use environment. Materials used in unexposed non-food zone areas shall be exempt from all requirements in 4. 4.1 Conformance with NSF/ANSI 51 Materials shall conform to the requirements of NSF/ANSI 51 applicable to the zone in which the material is located. 4.2 Solder Solder con

40、taining lead as an intentional ingredient shall not be used in a food zone or splash zone. 5 Design and construction This section contains design and construction requirements for equipment covered within the scope of this Standard. 5.1 General sanitation 5.1.1 Equipment shall be designed and manufa

41、ctured to prevent the harborage of vermin and the accumulation of dirt and debris, and to permit the inspection, maintenance, servicing, and cleaning of the equipment and its components. 5.1.2 Equipment shall be designed and manufactured so that water intended for ice production may be added, proces

42、sed, and/or finished, so that ice may be dispensed, removed, and/or served in a sanitary manner. 5.1.3 Food zones shall be readily accessible and easily cleanable or shall be designed for in-place cleaning. Units may be located behind removable access panels, since daily cleaning is not required. 5.

43、1.4 Food zones for which in-place cleaning is intended shall be designed and manufactured so that cleaning and sanitizing solutions may be circulated or passed throughout the fixed system. The design shall ensure that cleaning and sanitizing solutions contact all food contact surfaces. The system sh

44、all be self-draining or capable of being completely evacuated. Equipment and appurtenances designed for in-place cleaning shall have a section of the cleaned area accessible for inspection or shall provide for other acceptable inspection methods. The manufacturer shall provide written instructions f

45、or the cleaning and sanitizing of all food zone surfaces for which in-place cleaning is intended. The type and concentration of sanitizing agent recommended in the instructions by the manufacturer shall: comply with 40 CFR 180.9403; or be registered with the USEPA Office of Pesticides Program, Antim
